I bought this product 9 months ago and it totally worked. I used it on two skylights I have in my bedroom and its working. So far it’s surviving Arizona monsoon season. Thank you
Thank you for a very informative helpful video. I have a deep at the bottom of skylight (on a flat roof) and it is there where water pools. I have been told that there is an issue with structure...that perhaps on installing the roofer-skylight installer removed too much from the structure....that i need to replace....and resolve structure....What do you think Mr.Bergstromm shall we remove the skylight, fix structure....place that black thick membrane, that flat-roofers apply with torching and then re-install the skylight...? I am grateful for any advice. Thanks!
Thank you !!!! My roof is actually a slant although not standard, still a slant. This method is amazing !!!!! Super Silicone is fantastic. It easily goes on with a brush, but it's somewhat self-leveling so it gets in where it needs to, but at the same time, it doesn't run everywhere either. It's just the perfect consistency. I may do another coat as it mentions on the can, because the fleese really soaks up a lot. I doubt it will ever leak, but I opened the can of super silicone, only have a couple of other little projects, I might as well use it up.
The reason there is condensation between the layers of acrylic is cause the seal around the perimeter is defective. The cost of the skylight that size is minimal. (approximately $350-$400 for a Velux double dome) Skylights like that will last approximately 25 years. If the seal is not repaired properly the skylight will leak on the inside of the curb causing a lot more damage than just replacing it.
Really love your videos very helpful to people and appreciated. Thank you for taking the time and effort to really help. You seem like a cool guy and I applaud your efforts.
Thanks Brian - It takes an effort. Taking the videos on the site is the easy part. Editing them takes time. it can take 3 - 10 hours to edit a video. This one didn't take that long. I particularly love this video because I think this is one of the best Tips anyone can use to fix a skylight. I believe this product is a game changer.

A second question (my first is just below): Does this product hold up well under tremendous heat? I live in southeastern Arizona - that sun is not messin' around.
You don't know skylights. They atr designed for the water to run under the flange and out weep holes on the frame. Never do what this guy is doing. Take off the flange, repair the frame, and reasemble. This won't last. How do I know? I did it twenty-five years ago. Lasted three years. Had to fix the frame.
With the obvious condensation under the top layer of the plexi, it is clear that the seal between the two layers of plexi is leaking moisture and is no longer sealed. This method of "sealing out the weather" and water is NOT a fix. It is crap. This guy is just trying to make a buck and take off.
How can you tell if it's the sky light or.roof leaking. I have a leak lower left corner of my skylight 4/12 pitch roof. Also what silicone product did you buy? Thanks
This video shows that this product can be used on plexiglass, but my skylights have standard glass not plexiglass. I see that you answered a question below that this product will work on any material, including standard glass. So my updated question is: is it okay to SAND standard glass - which you recommend doing as part of prep in the above video? Thanks for the excellent demo.
NO. This man is showing people how to destroy the roof holding the skylight up. For glass skylights you use DowSil 795 caulk. You MUST clean it with 99% alcohol prior to caulking it. I pray that you did not take this mans advise. This is shoddy work, and will create a VERY expensive problem later on.
@@carllennen3520 hey thanks for this tip! I did not follow the instructions given in this video because he never replied to confirm if this method was suitable for glass. So what I did was just caulk the skylight lenses with "DAP Alex Plus All Purpose Acrylic Latex Caulk plus Silicone 40 year" . When it comes time to replace that (I fear that's soon, I live in SE AZ), I should clean the old caulk off completely with alcohol? I only have 91% isopropyl... is there a 99%? Thanks again for the info. I never totally feel worry-free about my three skylights that will leak without extra cautionary steps.
@Susan Taunton yes, you will have to replace that soon. It's just not a long term solution for glass skylights. Yes, they do sell 99% alcohol. You have to get it from construction suppliers. You can find them in any major city. They will also sell the DowSil 795 caulk. 91% alcohol will work just fine, it just takes longer for it to evaporate and become completely dry. DO NOT use denatured alcohol. It has an oil in it and won't allow the caulk to adhere properly, and will create leaks. Yes, you need to clean all of the old caulk off before recaulking. Use razor blades to scrape it off, then use the alcohol to clean the glass AND the metal. The alcohol not only breaks down the old caulk, but also removes all chemical residue that can stop the caulk adhering properly.
@@carllennen3520 Wow, thank you so much for this guidance -- your ideas make solid sense, And wow is it hard to get clarity on this particular topic. Normally the weep holes in the skylights would have been the solution, but our roofer plugged them up inadvertently, so now I'll have to keep on top of caulking these skylight lenses for the rest of my life in this house. Good to know at least the right way to do that! So I will look for the 99% alcohol, the DowSil 795 and follow your instructions to the tee. 🙏🏽
@Susan Taunton if there is any way to locate the weep holes, you should definitely do that, and take a knife or a screwdriver, and try to open them back up. They don't just allow leak water out, but also condensation. I think you said you lived in the desert, so condensation shouldn't be a huge problem, but it's best to have those weeps open. I build commercial skylights for a living.
Glad I came across this video. I’m not getting water leaks, but one of my skylights is really drafty. Looking to replace them in a few years during a remodel, so this fix is right up my alley.
This is a great video and I appreciate the effort you've put into it. I have two skylights I'm going to try it on as it appeared they started leaking last spring. Are you able to provide any info. on this fleece you use? Supplier/manufacturer name, where to buy etc. because I can't seem to find any info. on the net about it? Thanks much for your help
Great how to video, thank you gor posting it. Im having an issue with a skylight, one of the corners of the plastic skylight itself is broken, its close to the frame, do you think this method would fix that issue. Also does this dry over time rock hard. Hopefully you could answer my question looking to take care of this leaking skylight. Thank you
Nice video thanks for the helpful tips on roof repairs I’ve made so many mistakes in working on my flat roof. Your directions and helpful videos are going to save the day. Thank you
I have 11 of those 4'x9' dome skylights and during a storm the other day, something hard hit one of them making a big hole in it. Besides the water damage caused, I have to repair the bubble although it's missing pieces. Need help... anyone knows where I can buy a dome this big? I'm in Chicago
Mr. Flat Roof Doctor, my skylight isn't leaking, but there's a tiny bit of condensation on the inside frame (I see rusty screws). Can I apply super silicon seal to the inside frame?
Nice video! There is no supply of liquid silicone sealing in the UK, they only have the liquid membrane compound. I wonder if that would still do the work?
Is that how the manufacturer did it with silicone top caulk? The first thing is there is way too much condensation on the inside (first bubble). Pool? Remove bubble and aluminum frame. Separate the frame from acrylic bubble. Clean frame of old butyl caulk tape. Clean bubble with xylene solvent and frame. Install 1" butyl caulk tape and caulk corner splice with butyl caulk. Join frame and bubble. Install to curb.
Ok, why do you expect me to fix it the way the manufacturer did it in the 1 st place, it failed? The condensation is from a indoor swimming pool. I am showing videos for homeowners to DIY. You want them to not do it because it is too cumbersome. Your way would work, till next time. My way will work till a new Acrylic Bubble is needed to be replaced. Which one do you think people will choose?
Just noticed a leak in our skylight. Droplets coming from a crack that's formed in the drywall of the roof. Would like to fix asap but forecast calls for rain every minute for the next 9 days. Can I do this in rain?
lol that still amuses me. How people think that they can fix anything on a wet surface. Someone just asked me if it should be completely dry before making a repair. I almost told them, no, half dry. I don't get people.
Absolutely fantastic Tradesman showing how to properly repair skylights. I carried out his step by step guide on my 2 leaking skylights and worked perfectly. Hardware has drums of paint on super silicon seal and it looks great when finished. It's easy paint on.. Subscribe to this man for Sure.. Thanks for sharing your experience
Except this is NOT how you do it properly. I build and repair skylights for a living, and I would be fired I did something this shoddy. You see all the moisture inside that bubble? Thats not on the outside, its on the inside, and it has nowhere to go, other than into the roof. Where it is going to rot out that roof, creating a VERY expensive problem a few years down the road. I pray that this was his own building, and that he didnt charge anyone their hard earned money for this. If he did, I pray that they sue him for the new roof they will need to have installed later.
Siplast Parapro Roofing membrane is the type we use, very efficient and very simple! Except you use a catalyst with this one which you mix into the white liquid before installing.
Siplast makes one of the best products in the roofing industry. it is more expensive than other compatible products but much better. Thanks for sharing your thoughts.
This is my new favourite video channel. I have an old Queenslander with a tin roof. It has been painted a few times in the last 25 years so there's no rust to speak of but it still needs some TLC. I will upload a video if you would be so kind as to comment?
I just bought this stuff and just installed on glass slanted skylight. I hope it works. It goes on wet. I thought it would be thicker. I'll try another coat when it dries. Maybe tommorow.
i think this is the problem. You are correct to say it is Condensation. But, there should not be any condensation because it is a double layer of plexi glass. I think the seal that that was suppose to keep the air tight in between the 2 layers is broken letting that insulating air become cold causing condensation on the bottom layer. These plexi glass seals between the layers are not well done from my experience.
You do realize that asking "you do realize..." questions identifies you as an annoying know-it-all who doesn't care about the basic subject at hand so long as it affords you an opportunity to make yourself known as an annoying know-it-all, right?
Thanks for the video. Question what can you do when the rubber gasket doesn’t reach the framing and is not sealing properly on one side of the skylight?
The rubber gasket is normally found between the glass and metal frame. I don't understand what you are describing "reaching" Anyway, that is where Super Silicone Seal comes in. It breaches the gap between the frame and the glass.
Thank you for the value of your time to teach us all the proper way to leak proof our skylight thank you so much..

The dogs are letting you know you are not allowed to be outside, and talk, or do anything really.
I've done the exact same thing before using gaco silicon. Thanks.
Thank you so very much! I can buy the Gaco Silicon locally here in Arizona 👍

Thank you for this. Repaired my large skylight using these materials in about an hour. Saved $600 (cheapest estimate from glazing company).
Glad it helped!
Could you share what products you used? Which fleece product? Ty so much
I hate my skylights!!! Such a useless feature. Hot AF in the summer, can't take a nap it's so bright... Then I leaks!
Where should I buy these products? I didn’t find them in Home Depot.

How can you tell if it's the sky light or.roof leaking. I have a leak lower left corner of my skylight 4/12 pitch roof. Also what silicone product did you buy? Thanks

Very helpful! Mine has been a headache and I'm at my last bit of rope on it. Gonna give this a shot

But what about a cracked skylight
Glad I came across this video. I’m not getting water leaks, but one of my skylights is really drafty. Looking to replace them in a few years during a remodel, so this fix is right up my alley.

Where are you? Nobody will fix
Mr. Flat Roof Doctor, my skylight isn't leaking, but there's a tiny bit of condensation on the inside frame (I see rusty screws). Can I apply super silicon seal to the inside frame?
any way to customize this type of skylight so you can open it from the inside?
If this is a permanent fix, why don't people use it when the skylight is first installed?
will it work with glass ?
Our roof is a steep A-frame. Our sky light is leaking in the loft area and into the kitchen ceiling below the loft. How do I fix it?
sloppy work and no info on whether to wipe off plexiglass after sanding which seems to be a must!
If this works great x
it works. This skylight was done 3 years ago
Nice video! There is no supply of liquid silicone sealing in the UK, they only have the liquid membrane compound. I wonder if that would still do the work?
My skylight is leaking by the roof how do I fix that it's leaking at the bottom not the top can I use caulking for that
are you from South Africa your accent sometimes sounds like you are
Yes i am. I have been here since 1986
Great video! I need some of that super silicone seal.
Super Silicone is a game changer
This guy and his fleece.....go make coats! Stay off roofs!

Flat Roof Doc. Thanks so much for a great video. Do you think this process would work good for an RV, as it moves during travel?
So doc, I am going to build a tiny house with a flat roof. Is flexseal going to give me satisfaction, or will I regret it? It's going on 3/4" plywood.
Flexseal is not for roof coverings
Do your research
I love this TH-cam channel. 👍👏👌🙏🇺🇸
Thanks Jake
I can't find that super seal. Where can I find it??
i got a roof leaking house in Brisbane Australia. how can I buy this products to repair my house?
Did anyones teeth and jaws shatter when he started sanding?! Chalk board /fingernails.
Hello , what product is this?
Could you do a vid on how to open paint cans with scissors? I want some more details on that
lol. if that is to hard to grasp, then fixing the skylight would be far above your comprehension.
Thanks for comment. I like sarcasm.

Great video!! What is the compound and tap you were using. Thanks!
Super Silicone Seal.
Great video. My husband got some of this product and he likes it very much. Definitely a must have for your roof.
Thanks, I think Super Silicone is a winner
Where did you buy the product from
howbout a one piece skylight im sure it leaks on the bottom by the shingles

What is this "fleece" stuff stripping you refer to ?
Whats the name of the silicone ? From 🇬🇧
Very Nice Approach...
Thanks for the tips!
Might not be leaking in from outside you can see a lot condensation from inside the glass a humidifier might just do the job
There is an indoor swimming pool under that skylight. That's why you see the condensation
Where can I buy fleece paper and super silicone seal?

how to get t to india pls advice
Very useful video
Good video. Would this work with standard glass rather than flexi glass?
Yes it works on any surface
good one
Thanks
Thank you for your reply. Just a shame it doesn’t seem to seek in Europe!
bison rubber seal in europe.
Thank you for your video.
Thnx!!!😊
Great video! Thanks for the advice
I am glad to help
I thought you was a Dentist
Lol
This is my new favourite video channel. I have an old Queenslander with a tin roof. It has been painted a few times in the last 25 years so there's no rust to speak of but it still needs some TLC. I will upload a video if you would be so kind as to comment?
I am looking forward to see what you have. let me know
I just bought this stuff and just installed on glass slanted skylight. I hope it works. It goes on wet. I thought it would be thicker. I'll try another coat when it dries. Maybe tommorow.
Yes, it is more fluid so it will flow into cracks. This is by far the best and only product I have come across that can fix skylights permanently
It's definitely condensation heat from the pool hitting a cold roof light it'll still drip in even with that repair
i think this is the problem. You are correct to say it is Condensation. But, there should not be any condensation because it is a double layer of plexi glass. I think the seal that that was suppose to keep the air tight in between the 2 layers is broken letting that insulating air become cold causing condensation on the bottom layer. These plexi glass seals between the layers are not well done from my experience.
Will this hold up in Arizona's scorching, hot 115 degree weather?
Yes absolutely
You do realize that domes don't leak right!?
You do realize that asking "you do realize..." questions identifies you as an annoying know-it-all who doesn't care about the basic subject at hand so long as it affords you an opportunity to make yourself known as an annoying know-it-all, right?
I dont know it all but brakes my heart when stupid people try teaching something stupid
what is this polyester fleece and where would you get it?
It is a Polyester Fabric and you can get it here: bergstromm.com/product/poly-fleece-rolls-2/
Looks like the seals broken between its condensation
With his method stopped the condensation?
Thanks for the video. Question what can you do when the rubber gasket doesn’t reach the framing and is not sealing properly on one side of the skylight?
The rubber gasket is normally found between the glass and metal frame. I don't understand what you are describing "reaching"
Anyway, that is where Super Silicone Seal comes in. It breaches the gap between the frame and the glass.
