Painting roof with white reflective rubber acrylic elastomeric coating 

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

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.

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.

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.

Further 😊 more 👍it looks nice 🌞

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.

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.

About to seal my first roof, great insight! Hitting the sub button

Fantastic work.

I saw one guy use a push broom. It looked to work really well.

I loved your selection of background music. 🎶🎶

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.

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.

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 RU-vid 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.

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 !

Looks like you worked pretty hard at that I hope it works out good for you👍😊

Thank you for going through all the extra trouble to film and edit this.

Excellent video. I like best the tractor to get it on the roof. Them 5 gallons buckets sure can be heavy.

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.

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,👍

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.

This is the most interesting video I've ever seen for watching paint dry. Lol

Good job brother, love your commitment... by the way, she is right!

sweet kitty and chickens 😊

You had me at the hawk squawk. 💪

I’ve been using this type of stuff for a while it does work.

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.

This is a great way to seal in moisture.

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.

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.

good video man cant find much stuff on this with shingled roofs

BLUES THE NEW COLOR FOR ROOFS THESE DAYS ANYWAYS, wink wink

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.

Thanks for the video. How were the results? Can you paint this on a glass-reinforced plastic (GRP) roof?

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

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

Do you have any updates? I have a feeling the asphalt bleed through or shows through the white coatings. I could be wrong. But would like to see pics.

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.

You missed a spot lol . Good job & thanks for the tip !

Do you know if this can be applied when it is cold? Nice job.

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

It would be great to have white roofs in the summer and black in the winter

Nice vid! What’s the shortest time to wait between second coat?

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.

Looks good and at least in Florida that white roof would save you a 100 a month in energy bill !

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.

Can we used this stuff inside the house too or the atic?

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.

Is this the recommended coating for modified bitumen flat roofs?

Hopefully you accomplished your mission and bridged your water points of entry. Did it stop your leaks?

Thanks for your video I have a question I live in Arizona in a older single wide mobile home I was told once putting a coating on the shingles would make the corners lift up I'm hoping to keep the house cooler in the summer...Thank you

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 .

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.

Any update on this? Did the house get cooler or cooling costs go down? What about the leaks?

Did it work?. Fixed the leaks?

What does this stuff do for small leaks on asphalt shingles

can you provide an update on how this lasted through the summer/winter? any issues?

This stuff definitely works, but increases your cost to replace the roof as roofers need to remove it, which tends to be more difficult

How good does this reflect the sun? 80% reflect? Great video.

THANK YOU GOOD SIR!!! IM going this route instead of 8000...i think i can fork out 1200 roughly hope it comes in black? Again thanks!!!

How is it holding up after a year. Looking to do my roof.

Well, it’s about a year after you did it how did it hold up for you?

does it work on a flat roof with membrane?

After a year of having this how has it worked out?

The product might cost cheap but it's not a cheap product I've used a lot of time and never had an issues

Hey John - Good job - How's the roof coating performing now?

The question since it reflects more heat , does it feel cooler in the house.

Did this help cool your home? If so, by how much? Would you of done anything different? Like use less or more coats? And have you noticed any condensation build up inside yourbattic space?

Forgot to add: if your roof is absorbing less energy, it will last longer.

can we find same material in grey colour plz

Did it stop the leaks?

😊can’t you use roll hot rubber with 3” overlap?? Burn 🔥 in over roof old

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. :)

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! Rich

wow I've never seen that done before lol. is that stuff designed to go over asphalt shingles?

Results?? observations after a year??

Have my doubts that that's going to hold up long. Between the oil finish of shingles in the cold and hot weather. How about an update on how it worked out?

thanks for the vid... was helpful

How many buckets total? and how many square feet is your roof?

Wonder if it is a fire retardant or hazard. Would be excellent as a seal over the plywood covering of deck also, better than white paint/caulk in seams, if you want that extra.

how much did the project cost?

Kool seal makes another product for shingles that also comes in a few colors. Used it on my daughters house. Sherwin williams can order it for you

1- do you need a permit? 2- do you need to pre wash the surface?

I always wondered about doing this,I think the sqeegee brush combo like you use for asphalt sealer might work good on this product !

Hopefully it last. The mayor problem I see is to apply so much of this product until eventually overtime is so much of it that no leak can ever develop lol. Expensive stuff.

Just curious, by using so much of this coating, will it seal up any spots where water would have dripped down from any shingles? And about your leaks, do you know exactly where it is? Did you have to patch it up before applying this coating?

She is right! “Further!”

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.

The leak is most likely around one of your vent pipes , sounds like your tarpaper is dried out if the leaks not around any of the vent pipes …Make sure you seal the vent pipes properly and check the flashing

I've been watching as many of these as I can on both products that seal roofs ..I had my sprayed with something I don't know but it has made the shingles brittle and during storms my shingles are everywhere bits and pieces as far as across the street..but I just have a question with this rubberized elastin coating it's cheaper but ..did you have to cement down any lose shingles? Like on the edges? That's my concern..I may have to on mine considering how destroyed the roof is at this point.

What is the square footage of your roof? How many buckets total did you use for two coats? Thx!!

Further for sure

Using this outdoor waterproofing, how many years can it be rolled on the roof like this?

Do you think it would be a good idea to use this stuff on a metal roof?

We need an update though

Do an update and let us know how it is holding up.

Did this with Kool Coat on an ancient mobile that leaked everywhere. Fortunately, no shingles and in 100+ degree California desert summer heat, all the underlying materials were pretty dry. Built some roof shoes from sandals and pallet wood. Dangerous as hell but at least I wasn’t falling INTO the trailer-OFF, yeh maybe. (Serious lack of second hand snow shoes in the desert.) Repeated the process every summer for three years and at least the roof didn’t leak. Then came the grass fire…

How many buckets did you end up using? How many square feet is your roof? Also it says you can use a sprayer? Ever tried an electric sprayer?

What I'd like to know : is the music included with this product?
