Awesome keep on truckin .. looks great....in the event....water was to find its way behind .....due to unsealed metal along the roof walls...say,...would the coating pull away from the walls like skin ... leaving air pockets, wrinkles, and water underneath?....
The finished thickness should be a minimum of .22 mills. But some coatings can be applied with a thicker coat. Yes the existing roof should be properly prepped and repaired before installing silicone.
Cut a hole in the roof the size of the vent hole on the bottom all the way down to the decking then you screw the top side of the one way vents approximately 4 screws through the flange into the deck and then you flash it or seal it like they did
Attaching the vents with screws is not preferred@@ReidJohnson35. Only use a mechanical attachment if necessary. Just be sure to flash according to the roofing system manufacturer specifications.
@@user-it7kg3pm4q Thank you for your comments. I appreciate your concern about the durability of silicone roof systems and the use of polyester tape at the seams. With over 40 years in the roofing industry, and having personally installed roof coatings for over two decades, I've adhered to various manufacturers' guidelines and industry standards which do provide options based on specific project needs and warranty requirements. Aastro Roofing Company is top rated in the industry and prides itself on quality work for a competitive price. While the use of seam tape can indeed extend the lifespan of a coating system, it is not a mandatory requirement for all systems. For instance, the system we discussed does not explicitly require reinforced seams for the standard warranty coverage, as outlined in the manufacturer’s guidelines henry.com/fileadmin/pdf/literature/HEN_RoofRestorationTrifold_FNL.pdf It’s important to match the system specifications to the client's needs, whether they prioritize budget or a longer warranty period. Our approach has always been to provide the best solution tailored to our clients' requirements, and we stand by the reliability and performance of our installations. We're committed to delivering quality and value, ensuring that each project is executed correctly from the start. Please feel free to further discuss any specific concerns or needs. I'm here to help ensure the best outcomes for your roofing projects, but please, first do some research.
This manufacturer requires 2 coats@@MisterJohnMorales However there are manufacturers that let you use 1 coat. In the end, it depends on the thickness of the final product. Even systems that only require one coat many times will need additional application in some areas if the desired thickness in not achieved.
Silicone can be solvent-borne or air-moisture-cured. Acrylic is water-based and can be good for adequately sloped or vertical surfaces. Acrylic is NOT okay with any ponding water. Silicone does very good with standing water. Silicone also doesn't break down in UV light like acrylic does. While there are situations where I will use acrylic, generally I favor silicone. Oh yeah, NOTHING sticks to silicone... except more silicone. Acrylic can be quite coat-able and paintable.
@@Dubya84 well said. Never use acrylic or water based coatings on a flat roof. It can be used as a base coat to add tensile strenght to a silicone roof coating but cannot stand alone on flat roofing surfaces. Only use acrylic if the roof is properly sloped and drains very well.
Agreed, But anytime we install a coating or recover system over a concrete deck, we use one way vents for residual moisture. It is just good for the roof system.
When I use silicone, Gaco is the superior product. I live in Vancouver and our primer/bleed trap is red. Had no issues yet. Used Henry's silicone and that was nowhere near the quality of the Gaco. The biggest thing when it comes to this stuff like the majority of roofs is your substrate. It's gotta be really clean , really dry and the bleed trap is a must. Cheers
Depends on how thick the layer of silicone is for how many years it says it should last. There's millage measurement guide you can look at that'll explain it and also a millage tool that'll allow you to check the thickness of it while applying
NDL warranties of 10-20 years are available from some manufacturers, most silicone products have limited lifetime warranties for the product. Expect to get 5-20 years of life expectancy depending on the application of the product
It depends on how much prep and repair work is necessary, also what type of surface it is covering. Silicone roof coating costs about $2-$3/ft to buy the product, application usually costs about $.50-$1/ft. So roughly $2.50-$4/ft cost before any profit, overhead, or prep work. Total cost for the system from a reputable company should start at $5-$6/sqft and go up from there.
@@nesq4104 if the product is not used or installed properly, it will definitely have issues. We have had great success with silicone and continue to do so. Unfortunately, South Florida homeowners insurance will not allow for life expectancy of more than 20 years before they will require the property owner to replace the roof system.
Danny Reviews We use a "Butter Grade" silicone to patch any problem areas such as drain ends where there may be gaps in the metal flashing or holes. Then We apply the silicone in one coat. No primer. We spread it thick with rollers. If you do it that way, it's one coat application and will last 10 years guaranteed.
It depends on the manufacturer, some require an acrylic primer base coat, some do not. It is preferred for aesthetics and tensile strength. Silicone has many good properties, tear resistance is not one of them. Also asphaltic bleed through can result in discoloration. A good acrylic base coat helps to keep the product white and gives it additional tensile strenght and tear resistance.
So you only have a solution if it meets your requirements? Not all homeowners can afford to slope their roof. Your knowledge of code is flawed. This product is designed for roofs that hold water and does not require proper slope. What about coal tar pitch or Permamop roofing systems? These systems also do not require positive slope and are acceptable for new construction. The 1/4"/ft rule only applies if it is required for the roofing system. This roof passed all local plan review and inspections in South Florida which is a very strict code enforcement and ordinance. It was installed in 2017 and has never had an issue. It is inspected every year and is still performing very well. We offer solutions for roofs that sit under water.
I'm trying to buy a sprayer what kind would u guys recommend I'm not a business just got some diy projects that I need a sprayer for great video
Awesome keep on truckin .. looks great....in the event....water was to find its way behind .....due to unsealed metal along the roof walls...say,...would the coating pull away from the walls like skin ... leaving air pockets, wrinkles, and water underneath?....
It is possible but unlikely if installed and prepped properly
Buddy on the pressure washing needs some boots and rain pants
You can lead a horse to water, but you can't make them drink.
Do you need to remove old, chippibg silicone sealant before applying new coat?
Also how thick should the silicone layer be?
The finished thickness should be a minimum of .22 mills. But some coatings can be applied with a thicker coat. Yes the existing roof should be properly prepped and repaired before installing silicone.
Can you explain the process you use to install them 8 one way vents please I would greatly appreciate it
Cut a hole in the roof the size of the vent hole on the bottom all the way down to the decking then you screw the top side of the one way vents approximately 4 screws through the flange into the deck and then you flash it or seal it like they did

how did you apply the silicon finish??? rollers...spray// inquiring minds
This system was roller applied as it was only 1200sqft
So there is no need to apply seam tape at any seams?
That would be an upgrade to the system but not a requirement.
@@user-it7kg3pm4q no, it is not a requirement for this system.

How many coats of the silicone did you use?
Silicone is single coat, or should be if done right.
This manufacturer requires 2 coats@@MisterJohnMorales However there are manufacturers that let you use 1 coat. In the end, it depends on the thickness of the final product. Even systems that only require one coat many times will need additional application in some areas if the desired thickness in not achieved.
Any chance of the product availability in india either online or dostributor. What is the price or area of coverage?
The coverage is about 170sqft/bucket and a bucket typically costs about $400us
What's the difference between silicone and acrylic? Or which one is more effective?
Silicone can be solvent-borne or air-moisture-cured. Acrylic is water-based and can be good for adequately sloped or vertical surfaces. Acrylic is NOT okay with any ponding water.

one way vents? must be allowing moisture out?.. shouldn't seal moisture, not good..
Agreed, But anytime we install a coating or recover system over a concrete deck, we use one way vents for residual moisture. It is just good for the roof system.
What was the primer you used before applying the Gaco. Also what type of Gaco did you use?
Jim, the primer was acrylic.
It is Gaco Western S2000 High solids silicone
When I use silicone, Gaco is the superior product. I live in Vancouver and our primer/bleed trap is red. Had no issues yet. Used Henry's silicone and that was nowhere near the quality of the Gaco. The biggest thing when it comes to this stuff like the majority of roofs is your substrate. It's gotta be really clean , really dry and the bleed trap is a must. Cheers
Perhaps a chemical to strip off the left over residue?
Not required or necessary.
I thought the warranty for full silicone was 15 years or more
Actually 50yrs. But maybe there's other factors he's taking into consideration like the age and prior wear of the roof so far.

How much should this cost (estimate wise) when hiring someone to do this for you!
It depends on how large the job is. Small job I'd say in the range of 3 thousand

10 more years? No way. These guys will see 25 plus more years out of this roof if not much more.
Not
@@nesq4104 …You’re right. Silicone covering sucks.
@insightvideo6136 I read too many potential issues with silicone. I just opted to do a membrane instead and the price was basically the same
@@nesq4104 …Good choice.

I thought you are not supposed to paint the surface, i was told you apply the silicone directly without primer.

If the roof sits under water you should have brought it up to code 1/4" per foot.( building code ) Roof expert i think not

I wouldn't pay for that no tape on any thing
7 years and still going strong, not 1 issue on this roof since we installed it.
LMAO
7 years without an issue. This roof still looks and performs amazing
