- In this video I am sealing the roof with an acrylic elastomeric reflective roof coating in order to seal it up from those pesky hard-to-find leaks that occur on low-slope roofs.
This Lanco White-Seal Elastomeric Roof Sealer features a rubberized formula that will protect your roof. It reflects sun rays to lower your energy costs and it provides you with weatherproofing that won't crack, peel or crumble. This sealer can be used to waterproof a wide range of roofs including conventional bituminous built-up roofs, metal, concrete, bonded tar and more.

As a professional painting contractor for 50 years, painting, a roof is an extremely good idea! So many misleading comments that are totally wrong! My personal residence has been painted since 1961 still going on the original roof! Why more people do not paint their roots beyond me
Wow. Replacing shingles must be a scam then.
@@reliefmango6🤣😂dairyhill9400 Just wants to paint roofs ..😂
@@user-vq1lr6nh4v I mean industrial buildings don't mess with shingles, they just paint white reflective elastomeric every 10 years for $2000 instead and it works damn well.
@@reliefmango6 This stuff keeps the wind from getting up under the shingles if applied correctly.
Simple math, your average single roof has a 10-25 yr lifespan but the insurance companies give any roof that is 10yo a zero cost. If your roof shingles are in good shape, pull a permit for elastomeric roof paint and reset the clock. Note that if you are really going per product approvals we are talking 50-100sf a 5gal bucket and make sure to treat cracks and joints with other products.
Great job, i did this 4 years ago against everyone saying not to. It was the best thing i did, it gets windy and blows shingles off in our area and i no longer have those issues but the neighbors do. In a few years i'm going to hit it again with 2 coats just cause.
do you feel a great difference in temperture during the summer time inside your house?
How has it held up and did you notice improvement in temperatures throughout your house
whats state your in im in Fl thinking about doin it
@@JoeGarcia-cg1pp just be careful though sometimes moisture can end up getting under the cracked area and rot the wood underneath
@@akanesoratobu8889 Yes I used silcone white for a roof that is in direct sunlight if you put a white coat on, then you should drop you attic temrpreture 30 degrees and your AC bill 20-30%. Just keep if you use on regular shingles you are choking the breathablity of your roof off. Make sure you have good attic ventazlation or you may get mold. I think the white liquid rubber will do the same
I painted my roof in Bullhead City Arizona with Snow Seal, it dropped my electric bill by 30 percent and stopped a roof leak... its a great product.
Worked in Arizona in August with temperatures over 120 degrees in the shade.
brand?
@@coleccionistademetales Ames Snow Seal. There are other good brands as well. If you want to get serious, spend the bucks and get a silicone based roof coating. There's one out there with a 50 year warranty.
Don't cheap out and barely coat it like this guy did. This is a very poor job.
I have used this product.
1. make sure the roof is clean first.
2. make sure to mix the product well.
3. It will not stop all leaks.
4. It will reflect a lot of heat from the sun. Very important when it is 115 degrees in Arizona.
5. It does last a long time. Must be pressure washed before recoating years later.
@@tedwalker1370 every 5 to 7 years recoat but once you achieve a certain film thickness, it takes less paint each time I’ve been doing mine since 1961
Make sure the keyways are sealed. If not, water will enter and travel horizontally until it reaches the gap between shingles and leaks. Don't ask me how I know this
Have used products like this for decades. Points to consider:
1. Sealing cracks requires the thicker paste version and mesh fabric, almost like fiberglass layup.
2. This is a plastic seal which will trap moisture coming from inside your house. Proper ventilation is absolutely required. Most folks don't realize that shingle roofs breath. Not with this coating.
3. The coating does protect the mineral coating on the shingles, which could help extend the life of the shingles. However, you cannot walk around on the roof without breaking the coating.
4. Multiple coats works much better than one thick coat.
Great video and yes it works!How I did it as an aluminum contractor:
Tint the paint gray then while youre rolling have someone follow the wet edge and scatter multi colored sand with a fertilizer spreader on lightest setting and youll be surprised hom much it ends up looking like a newly shingled roof😎
And vayla you have a house that looks like a mobile home!
@@johnrogan9420 a mobile home is a mobile home regardless of what the roof looks like lol
I bought a short sale Phoenix house in 2009 with this on the roof. Makes zero difference in heat gain. Last forever? If forever is 5-10 years. 99% of it lasts, but it starts cracking different places. That allows water to get in between the layers. When I ripped the roof off most of the roof was wet and rotting thru the wood deck and rafters. It rarely rains here in Phoenix and when I ripped off the roof it hadn't rained in months. Still soaking wet.
Does a really good job of trapping water and sealing it in.
Couldn’t agree more. This is absolutely NOT the way to go. LOL!
Thank you, that's logical information, cracks. I now know never use it. Was thinking it good but now the truth
That should always be a concern when coating anything; remember what undercoating used to do to cars? But it seems to work for some people, maybe for the ones who check it for cracks regularly, and re-apply it to stop them; it it doesn't crack, it won't likely trap moisture. My inclination, if attempting something like this, would be to staple down fiberglass mesh, then put the sealer on through it. I've done that (without the staples) to a few metal items that wouldn't stop rusting. It has protected a metal cabinet, which had been a rusty mess, in my bathroom for over 25 yeas.
@@pcno2832 yeah remember the undercoating days it was a gimmick. The dealer would add $1,000 to the car for undercoating, so a guy with spray cans of goop would coat the underneath. We used to get driveshafts that had been coated on one side and vibrated. Brand new car, vibrating.
Probably your product wasn't the silicone type.
Realistically, we cannot know if you are "in-defense" of traditional roofs because of incentive.
As a Paint Contractor for 40 years I agree 100% We had a client who needed a new roof but as a lark asked us to paint it, that was 25 years ago and it still looks great
Do you know if the insurance company accepted it as a roof replacement, by chance?
@@NineToes19 I don't remember how they dealt with it, We did the job and I still drive by, still looks great. The family sold the house and the roof is the same, thats as much as I know
@@willisjefferson5886
Thank you.
What kind of paint/sealer did you use?
@@godkung1 We went with Old School Latex paint on Asphalt shingles. We painted it Terracotta red. No prep, no wash. He hoped it would last 6 months, its still there
I have done this on a number of properties I have owned over the past 40 years. I started off using SiverDollar which was an aluminum paint with asbestos fibers in it, it had to be mixed VERY well before using but worked well and it was very messy since it had a petroleum base and you had to use paint thinner to get it off of you. The next time I did it I used white acrylic, worked good but became brittle ( cracked, when you walked on it). Ever since I have used a white elastomeric like you did, fills the cracks or small holes, dings or whatever. It doesn't crack because its a rubber. I have even used this on shingles so old that some tabs had lost 90% of their rock like granules, still worked and from standing in the yard looks like a brand new roof. I have read some of these post and a few have said you need to remove the old finish before recoating. That's just pure bullshit. I did however start by using a leaf blower at the top and walk down the roof to remove loose leaf stems or whatever. I'm ready to do this again its been 12 years since I did it last, still doesn't leak and the shingles that are on the house now were 30 yrs old when I did them 12 yrs ago. A contractor wanted 8k for a new roof, so I will be doing it again.
Very useful tips Thanks , I'm a bit skeptical maybe I'll reroof my garage we'll see .
You touch on one thing some commenters dont realize, this elastomeric coating does not crack. I am planning on putting this on top of a brand new roof when I re-roof my house mainly for the heat reflection, but I have put it on the flat roof of the house Wild Bill Cody lived in the late 1800's, this stuff can stretch and give even once it is dry. It is very popular here around Tucson, AZ. We arent quite as hot as Phoenix, but close.
"Pro tip : pay attention when you're up on a roof". This guy's a genious!
But wearing crocs on a roof doesn't seem like a smart idea.
One observation, you need s systematic approach, some areas look sparse while others are a foot thick (well maybe not a foot) the coverage does not look even. I am on 15 years with this stuff on my roof in south florida and I no longer hear the rain, the leaks stopped and my electric bill went down 20% in the summer. I have now about 6 coats. i put two coats on each tome about every 3-4 years just to keep preventative. Each time i use less product but i have a very systematic approach to ensure even coats. Even withstanded hurricane Irma.
I've had lots of comments asking about an update. I haven't been able to film one yet but the roof has been holding up quite well, and it feels and looks the same as the day I put it down.
What about a energy bill reduction due to much cooler temperatures in your attic?
@@FiveTimesLife @JohnBlOutdoors
This is the real question. The energy savings.
Yup, I'm curious too!
Most comments were around moisture in the roof. Suggest getting a wood moisture meter and spot checking from inside the attic. That would be the best way to identify problems.
why is there no response regarding energy savings and did it make the house cooler on the inside? people are curious!
Lanco white seal is good stuff. Manufacturer recommends a thickness of 20 mills about 2 credit cards thick. At that thick it would take you 8 coats. I've seen a shingle house that was coated like this and it was sealed so good that moisture couldn't go through the shingles. And there was condensation in the Attic. The homeowner had to install more vents in the Attic to let the moisture vapor out.
Shit..are you kidding me?? 8 coats??? It's pretty thin..not much heavier viscosity than latex house paint so Maybe you're right 👍
But that would require 50 fucking gallons
Sounds like mold will develop
Yes , I agree- Looks like crap 💩 too.
Plus its $200 bucket
Badass
so anyone who knows roofs knows its the granuels on the shingles that make the shingles last so painting helps them stay on good video
Our shingle.roof was dried out and needed replacement here in South Florida but we didn't have the money. We had a small leak. I used this product and painted the entire roof. 3 coats. It bought us 3 years! Didn't really lower any electric bills but it held that small leak at bay. We now have a new roof but this did the job in a pinch.
I used the same stuff to paint the steel decks on my 38 foot sailboat. Works great and now I can walk barefoot without burning my feet. The trick is paint an off white top coat as to not get snow blind.
Big mistake he made was back rolling over his initial roll. He was literally pulling the product back up off the shingles. You have to lay it on and leave it be. When it is real hot like he was working in, the coverage and workability goes way down. I used to use a mold/fungal spray first, let it sit for a day or so. Then spray a clear roof sealer on with a pump sprayer, let dry and cure a day or so. Then, go back with the elastomeric and lay it on, trying not too get too cute with it. If it is really hot, it is okay to spray the roof with water before applying, it cools it down, and the water evaporates pretty fast. I have done roofs like this that have lasted 15 years in South Florida, and The Keys. I used to put M9 in the product, it is a anti-mold, mildew fungicide that keeps molds etc... from growing in coastal zone tropical, and inland sub-tropical areas. Basically you are covering your roof in a big raincoat, and a clean base is always a good place to start. Poly/Styrene spray applications are expensive, but provide incredible insulating properties. The problem with that system is you have to keep painting it to keep the UV rays off of it. The best roof is a Bimini roof which is basically overlapping stepped concrete slabs that can take any hurricane winds, provide a monolithic slab that also insulates the building and you never have to put another roof on. It does require painting for aesthetic reasons as well as to protect concrete from weather. Insurance companies in Florida consider a 15 plus year old roof non-insurable, which begs the question about thirty year shingles? Everything is a racket.
I love your suggestion about the spray on fungicide....and....the clear sealer first before applying the coating.
I remember when they invented that rubberized roof coating material. I was working a/c and on a rooftop of a mall where it was poured/spread in patches here and there with standing water on many patches. The owner told me they had constant leakage until he found and used the rubber material. He only used it in patches as it was quite expensive at the beginning. But it stopped the leaks in areas where the rain water ponded.
I wondered sometime afterwards if this material could be used on a slopped shingled roof for a situation like in this video. Glad I finally got the answer. Other than dripping over the edge I never saw a reason why it couldn't be used. And if the shingles are whole and not breaking the appearance shouldn't be bad. Seems better than removing and replacing shingles. Maybe less expensive than using steel roofing too.
We have a simi-flat rock roof & I did this 4 years ago sweeping the rock up & coating the with Henry's DuraBrite & then replaced the rock & it worked great & it did indeed lower the temperature.
I did my roof 3 1/2 years ago in 2021, huge improvement. It does really help cool. I am in the Mojave Desert in California. Plus it helps waterproof the home. Pretty inexpensive for the benefit, I would definitely do it again. Nice work
This is the most interesting video I've ever seen for watching paint dry. Lol
What you mean is the distance! It will cover more lol
Thanks for doing this video. Very helpful as I am looking into doing this myself. I was looking into Lanco because it's a third of the cost of Henry's. We're located 200 miles one-way from the closest Home Depot that carries Lanco. This last winter, we were pummeled by a month of 14-25 degree weather on top of two-feet of snow that froze to the roof. My 2650-sf flat roof is only six years old and I've been quoted $28,000 to $40,000 for full applications of GAF HydroStop or Elastomeric on the old roof, with no warranties, or only the product warranty or a minimum 2-year warranty. One licensed contractor has offered a complete roof replacement with a two layer coat of Henry's TropiCool for $32,000 plus $115 per plywood sheet needing replacement (39 sheets)--he can't get up here until November and even that looks sketchy because they're now dealing with Hurricane Hilary damages. I figured with a four-inch brush as shown in one video, I can get it done before October, however, the Lanco Company TH-cam video says to spread the material thickly on the roof, not to roll it. I'm heading up to Carson City to pick up a few five gallon buckets to try it on problem areas before it rains again. My heart goes out to all that have been impacted by the weather, most recently those folks in Maui because some folks aren't going to be able to afford the sky-rocketing prices, considering all materials have to be shipped by boat. Even if you file a claim with your insurance company they may pay for it then not cover the roof going forward, increase your premium or cancel you anyway even if they don't cover it. It's a mess all over the country.
200 miles from HD, wow. Maybe you can have it shipped directly to you. I'm happy with the product, and you're right, you don't roll this product on, really just push it around nice and thick. That the best way even though I used a roller on my roof.
The tropi cool is a vastly superior product. Can walk on it barefoot on a 90 degree day and not even hot. Lasts way longer and does not crack like the latex.
Farther regards physical distance. Further regards progress through a process.
I used regular exterior grade latex paint on my roof. Not thick like you did, but just a regular coat of it because it actually does reflect the heat and keeps the house cooler.
My former employer used a similar product on our 11,000sqft industrial shop that had a plain galvanized metal 1:20 pitch roof. Yes, the roof was insulated, about what most red-iron construction uses. By adding that white coating, it not only sealed what leaks we had from the 25-year-old washer-gasket type screws, but also lowered our cooling cost (yes, an air conditioned industrial building) to the point where the whole thing paid for itself in just three years.
Whatever product we used, it was a two-stage process after the initial acid-etch/powerwashing. First a bonding primer was applied, then the rubberized white top coat was sprayed on. IIRC, our building used ~250 gallons of each product, primer/topcoat.
Henry's DuraBrite is the best I've found ... save money and animals .. coated my chicken coop and lowered summer Temps to comfortable in panhandle Texas.

I have often wondered about doing something like this. Seems like a quicker, easier and cheaper way to avoid complete tear down and replacement. So long as you do it while your roof is still in great shape. I did not consider moister through shingle. I know I have that moister barrier under shingles. That white tarp like looking material. Watched roofers put it on when I payed for a complete replacement. Ben 15 years about never had a leak.
I saw one guy use a push broom. It looked to work really well.
The stuff works well on metal/aluminum roofs. I usually pressure wash roof early, let dry, and then apply. I apply a thin coat every 2-3 years. I do not like thick coats.
switched over to this on 10 mobile homes and most started leaking after a couple of years, the aluminum roof coating works best on older mobile homes, also mildews after couple years.
I literally thought of doing the same thing; genius or dumb… time will tell. Thank for making the video!
Excellent work and the white paint will definitely reflect the sunlight I proved it for myself. So the inside of your home should be a bit cooler.
Thank you for going through all the extra trouble to film and edit this.

👍it looks nice 🌞
This works great for animal shade shelters . My hogs loved it. It would be an oven without it.
Works great on trailers. I have same trailer roof since 1969! My cooling bill is a fraction of being without it.
Just did my very low pitch roof. Had roll roofing on it that was not leaking, but the white granules were wearing thin in some areas. Two heavy coats . Let first coat thoroughly dry . Weather was very hot. Second heavy coat went on great and looks great. I'll remember posting this and be back next year this same time. I'll share the results. My concern is the heavy coat peeling after winter snow and spring rains . I used Duck brand white coating. 5 gallon bucket cost a 100 bucks. Covers great. We'll see how it holds up.........
Like to see how this holds b up after 5 years. I can see it maybe peeling and seeing that bond failing over time. With shingles being petroleum base and acrylic would have different expansion rates during freeze thaw. Its probably just a band aide for now but who knows. Any you tubers have any experiences with this or any other roof coatings please chime in.
The Mrs & I put this stuff on a low pitch asphalt shingle roof when We lived in FLA . Just stirred it & dumped it on the roof , used heavy nap rollers , worked like a champ . Before the roof was dark gray and yes one could fry an egg on it , easier to cool the place .
Two coats of Henry Acrylic white roof coating. It is now right at 19 years later and the roof is still totally intact! The stuff is amazing!
I loved your selection of background music. 🎶🎶
It would be great to have white roofs in the summer and black in the winter

I live in a mobilehome park and many residents have coated their roofs like this. No leaks and it extends the life of their roofs. They applied it over shingles.
I'm glad this video was recommended to me. This is my pending project at the moment. Excellent job.
There are so many houses in Tucson with rubberized roofs that there are actually multiple manufacturers *based* in Tucson. Elastek and Tucson Rubberized are the two biggest ones.
Roof coating is not a sealant. They only protect the existing roof from sun damage. They also help with energy efficiency. If you embed it with polyester fabric, then it will seal. It is not suggested to coat shingles because if you do not have proper ventilation, it will destroy your wood substrate.
So when I paint the wood on my house the wood will rot because it is sealed.😅😅😅😅
Excellent video. I like best the tractor to get it on the roof. Them 5 gallons buckets sure can be heavy.
It looks a lot better than you imagine it would have. 👍
Pls tell me how much this paint cost, how much did you need, and how long did it take you to paint the whole roof
Dude...we understand it doesn't matter which word you choose I've done that roof coating stuff before that Sun effect on the body is crucial...hopefully it fix the problem...
Thanks for an interesting vid. I'm looking into 100% silicone which apparently has some breathability, resists UV, and is less likely to crack.
You correctly said, "I'm on the second coat now. It's definitely going farther than the first coat".
It's a comparable, tangible, and measurable amount. Your first intuition is correct, and it furthers your goals of saving money on the roof. ;)
I believe this is the same rubber roof stuff used on a lot of Rvs. The mfg recommends refreshing the
roof coating every 8 years HOWEVER, before that is done, they want ALL of the old coating removed.
good luck with that.
!
Good advice about not falling off. My friend was powerwashing and fell off his roof, he is now paralyzed
That was no hawk.
That was a buzzard mistaken you for lunch, as slow as you were moving on that roof he thought you were dead 🤣
Cool job !
I've been using this product for years . If you put 3 coats on any roof it will last better then 20 years . I have a travel trailer that i did 30 years ago and no leak yet .
And what about flat roofs
@@debbujol5571 it will work great on a flat roof as well
I want to do this but the HOA won't allow it.
Its a great idea. It seals your roof , is cheap and reflects sunlight making your house cooler than it would be without it.
Did he cleanup his roof with soap and water? I use the highest silicone base roof paint as possible. Have done this for years and it pays to use the best quality roof paint possible. Two coats are suggested to cover roof properly. I use the highest silicone solution as possible on the valleys of the roof. Easy to do! I’m sold on this way of sealing an old roof.
This stuff definitely works, but increases your cost to replace the roof as roofers need to remove it, which tends to be more difficult
do you have to prime it before using this stuff?
their was a video where someone did this on their mobile home roof and since he didnt seal it correctly mostiture got underneath and rotted the sheath wood underneath.
@@akanesoratobu8889this looks like a trailer house they are putting it on now
The future tear-off was one of the first things I thought about. Those shingles were older 3tabs. The point being it likely will not be too long before the shingles need replacement (as well as possibly needing to replace some plywood) etc, etc. I'm curious how the tear off will go with the installed coating.
This stuff is absolutely amazing use it quite often had a tree limb hit a spot on my roof made a big dent in it I coded it with that several years ago it's like a big bowl of water up there never leeks
No, acrylic coatings cannot indefinitely handle standing water. They are not recommended for that application. They will peel in time. Only silicone coatings can, indefinitely, handle standing water. The only downside of silicone is that it tends to hold dirt.
I have a commercial building. It has a flat roof. We coated the roof with acrylic coating. It works well except where there's standing water. There it peels in time.
If you have pools of water keep an eye on them. When it peels, coat it with silicone coating.
We have a small park home in AZ where we snowbird. While walking the dog, I saw a guy putting this stuff on a roof and stopped to ask him about it. It's a small roof and he said it would cost about $1,500. But I got a quote for a new roof for $3,000 so the savings isn't great. Water can get through the smallest crevices. I'm skeptical that this stuff seals leaks. And I'm skeptical that it makes it cooler inside the house. I'd like to see a true before and after study on that one. Lastly, I just don't care for the look of the finished product. When considering all of this, I'm going with the new roof.
If you were here (Arizona) in the summertime when the long days beat 110 to over 120 degrees on your roof, you'd appreciate having a thick white roof. Not needed the rest of the year.
White rubberized roof coating absolutely work. My house has had it for at least the past 30 years in one form or another. Once we had a film of foam spread down first and then sealed with the coating. Now, there are so many coats of the sealant that the house is super insulated. Inside temp of the house in the peak of summer (AZ) with temps 100+ will max at 80 degrees. Then, flip on the evaporative cooler and it gets down to sub 70 in a couple of hours if desired. The coating works, and works better as your layers of the stuff deepen over the decades.
We use this to cover a concrete roof and it worked fine stopping the filtration of rain water through the concrete, but I won't put it on a shingle roof. If you live a trailer in Arizona, build a patio cover over the trailer as I seen done there.
I used this stuff on my metal roof, 30x18 shop and 15x15 porch in Florida. Dropped shop roof temp inside by 25 degrees. Dropped the porch temp on the back side by 31 degrees !! I’m a little scared to use it on shingles though
Is it holding up well? Thank you😊
getting ready to do my roof here in Florida, temperatures are creeping into the nineties already, So, wanna get it done soon, It Looks like a good product, Home depot, has product called Henry, Which is over $500 but it's a 100% silicone, I think I'll go with the lanco,? Hey thanks for the video, I had no idea I was gonna be entertained, by one of my favorite composers, Love me some Vivaldi. Thanks again,👍
It depends upon if you are talking about stretching the paint out or Covering more distance. Both are correct depending , Materials vs. Distance... good one none the ness...
I have this on my roof. I just go up each year and lay down another coat. 10 gallons a year. So about $250 a year. Cheaper than getting a new roof. I have a weird roof.
try liquid butyl rubber

White roofs in colder climates can be more likely to develop condensation, especially if they are under-insulated.
This can happen when warm, humid air gets into the roofing system through gaps, unsealed joints, or around penetrations during cold weather.
When the humid air hits a surface that's below the dew point, the moisture condenses, usually on the underside of the membrane.
Thx I’m 66 years old , I redid a roof with new shingles new sheathing 15 years ago, I got the 25 shingles I live in California, So no snow and not a ton of rain but I think for my 70th birthday I will do that have to redo the roof at all at least in my lifetime
My old Greek neighbor growing up painted water towers for a living. He would paint his roof shingles every 2 years with a silver coating. He never needed a new roof. Imagine what that weighed
We had an old greek guy paint the water tower in our town with American flags back in the '80s because he loved this country. The city has maintained and repainted the flags ever since!

I used a 100% silicone coating (Henry's Tropicool) on the roof of my 20" cargo trailer. The roof is sheet metal and I could not put my hand on the underside of the roof of areas where I had not applied the coating and the area where I had applied the coating, the roof was cool to the touch. AMAZING! So to say there is no heat gain difference between the old dark roof and this new white elastomeric coating is a bit hard to believe. Unless the elastomeric has very different heat transmissive qualities, I don't see how it does not keep the home cooler.
Looks like you worked pretty hard at that I hope it works out good for you👍😊
I have worked with Elastomeric before ,after being under rain water for a short period of time it bubbles and separates from the surface it was applied to. Now in a different situation itmight do better ,but if your in a rainy state avoid it like its a plagued.
I would definitely do this if we didn't live in a neighborhood with an HOA. The Texas sun is no joke.
The product might cost cheap but it's not a cheap product I've used a lot of time and never had an issues
Hope you don't trap moisture under roof causing rot in wood. Comp shingles are supposed to breath. Make sure you check your attic for possible rot and mildew buildup because of trapped moisture from the home that can't get out of your roof. It does look like your roof is well vented but I would not recommend sealing a roof this way.
as long as air can get in attic never have a issue
I think if you were to dip your roller INTO a pan of the paint (or even directly into bucket) - you'd use far less, it would spread farther... and it would go a lot further. By pouring it out onto the roof, you have that one giant "clump" you then have to spread - causing a lot of the paint to stay right there on that spot. Just food for thought. :)
A lot videos show people applying the product with paint brushes. There is a Lanco application video on TH-cam. They say not to roll it like paint, but to spread it. th-cam.com/video/kZJesRahTJs/w-d-xo.html
Rollers will spread it too thin, not appropriate for this type of product which is meant for completely sealing the roof.
My son and I just finished painting our roof with the white elastomeric paint using rollers. We used paint trays, and poured it on directly.
Pouring paint directly on the roof, and then spreading/rolling it downward from the top, letting gravity pull the paint down the roof slope works best …easy breezy! We used 13 x 5 gal buckets on a 2700 sf roof
As well as the temperature of the roof.. never paint in direct sunlight. Or heated surfaces. The paint will dry fast, and won't spread as far.
This is a great way to seal in moisture.
So, I always wondered if it could be done and here is a video proof ... Good Job guys ... Will my HOA approve this ?
For trailers ok but i would like to watch the guy who actually removes this type of sealed roof 25 years down the road. Extra labor and extra cost at future rates. What did you gain?
Expensive stuff? Nope, 7 buckets @ $105 = $735 with tax was cheap in my opinion. 10 years later he can do it again. That's 20 years for less than $2,000. Think of the cooler temp the home will be in the summer. Great job John! Thanks for sharing.
the problem is, you saw how it was applied, that's not stopping leaks... there were holes EVERYWHERE
@@notimportant3686 The holes should be plugged.
@@notimportant3686 this is for deflecting the suns rays why are you talking about leaking?
Oh never mind. I guess this is for leaks. I want to do this just for the heat reduction
That pitch doesn’t look like it should be shingled in the first place, that’s the reason for your leaks!!! SA Base & Cap. Only problem here is if any water/moisture builds up it’ll stay and rot everything.
John Bull, thanks for this, good job. I'm in Florida and will be doing this soon. Advantages here: 1. Energy Savings, less A/C needed. 2. Extends the life of the roof. 3. Protects against Hurricane winds!!! We've had 115 mph winds in our backyard, so far that has been the strongest. But the way the "Climate Change" is happening and our water around Florida, much warmer. stronger winds in our future. Roofs come off because the wind gets UNDER lose shingles, which no longer can happen after this Lanco application.....
I have State Farm and sent them photos of a small section of my roof that I painted with Lanco. Also the difference in the heat coming off the roof, 140+ to 107. I sent them the product information and how it's used around the World and they will write me a letter saying that this will NOT affect my Homeowners insurance!
Here's a suggestion for the NEXT roof you paint. Use a cheap push broom, cover a lot more area. THEN, use a cheap garden sprayer, and use that AFTER the broom. May need a roller too. OR, bite the bullet and buy a cheap $200-$300 sprayer, use it and then sell it...could ALWAYS rent one too!

In Florida also, inside my attic yesterday was 142 degrees....yikes! Thus why i am watching white roof videos.
So far, 139 here! Have some blown in insulation which helps, but just need to get the paint on it. On a test I did a few years ago, the shingle roof temp. was 140 and just over, where I painted a section white, 107! So who know how much cooler the attic would be, but never near 140!@@callmebigpapa
Wind getting under shingles will simply expose the flat sheathing, wind goes right over it. When roofs tear off it because the wind gets under the eaves and lifts up, combined with poor construction/ lack of adequate truss/joist connectors.
Apples and oranges. You're talking about the wooden part of the roof getting blown off and I'm talking about the shingles themselves being held on by this "paint" method. Here in Florida, see LOTS of roofs with patches of shingles blown off after a storm/hurricane and this would stop that from happening....@@Matasky2010
I'd like to see you spray that thick stuff through a garden sprayer.
I love diy videos when they break out the bobcat
I’m a handyman, I will tell you that most of this sealers work, but you have to do it again every other year , way better than paying thousands of dollars for a new roof.
Thank you .l was wondering how .love the fast motion. 😂😊 today is sept 17 24 . How long has it been .for your roof at this date.
can you provide an update on how this lasted through the summer/winter? any issues?
It's been about 9 months since installed. It's June and the weather is starting to heat up here in TN. The coating is holding up well. You can put your fingernail in the coating and see that it is still soft and pliable.
About to seal my first roof, great insight! Hitting the sub button
Good job brother, love your commitment... by the way, she is right!
I'm lazy, so I would just stand on the peak of the roof and keep pouring buckets down until the roof is covered. The gutters will catch the excess. Done in probably an hour.
I don't know about this product but I worked for a major roofing outfit here in PA they did all the rooves for the power company here and they always put silver coat on the brand new rooves they put down at the electric company's request swore it added a minimum of 5 years to the life of the roof
After reading the comments, I think the concerns around trapping in moisture are legit.
This product also solves a legit problem, but while possibly creating another. I think the root problem is that roofing shingles in hot climates aren't reflective to begin with. And they aren't durable enough. That causes consumers to do things like this.
If every shingle were individually coated prior to installation of the roof and dried prior to install, I think it would be fine. I think moisture could escape because the layering would still exist. And it would be both reflective and durable. That's water under the bridge at this point though.
Looks good and at least in Florida that white roof would save you a 100 a month in energy bill !
I did this to my home 20 years ago. My electricity bills were cut in half. I only had to do it once every 3 or 4 years maybe just to touch up...
That's great. It's been a few months now and so far it's looking good still.
@@JohnBullOutdoors
That's awesome. It's a good product.
No visible mold and mildew so far?
Can I this with flat roof? It should be easier since it has only modified bitumen.
Wait till your insurance company grabs a satellite picture of that
I think they use drones 😅
If building a new hour or replacing the roof on an existing house, would you need shingles at all or could this be spread over plywood and tar paper? It seems to me the seal would be better without the knooks and crannies of the shingles. Could definitely be wrong though.
Can we used this stuff inside the house too or the atic?
Good way to make shingles last longer
Buy gacco roofing sealant. Kind of expensive, bit it'll last you a long time and you'll have no leaks. It's not cheap, but we'll worth the investment
7:00 Further is a great distance that can’t be measured. You are going farther than the 1st coat :)
Farther / further, on the one hand, isn't difficult. Further applies to one's state of progress in some endeavor, whereas farther relates to distance (though exceptions almost certainly exist, and especially with local usage). However, when your endeavor relates to covering some distance - say - then you can use either, once it makes idiomatic sense. These adverbs are misused often, but nothing like the current confusion with the adjectives lesser / fewer; where fewer relates to some countable quantity, such as "fewer people", and less (or lesser) relates to a non specific quantity, such as "less rain today", though "fewer inches of rain today" would also be appropriate since one is being more specific.
Thanks for the video. I also would have some concerns about the "sealing up" of the roof, without first verifying that there is ample ventilation in the roof or ceiling cavities, assuming you have access to those, or the vents are visible from the outside.
Glad to see you wearing a wide brimmed hat along with the sun glasses. Keep safe!
