Rated 4.0 out of 5 by 17 reviewers.
Rated 5.0 out of 5.0 by Very good product. Am buying again this week My carport was leaking from some seams. (3in foam alm both sides ) can walk on. I painted one coat then 6" fiber mesh and another coat of White Seal. lasted 8years had my roof pressure cleaned started leaking again now am buying a 5gal and doing it again. it's more then I need will save for future use. I put mine on with a 3" brush not a roller. (I am now 80) August 25, 2016
Rated 5.0 out of 5.0 by Applied to my worn out 20 yr old flat roof Worked great on my 2,400 sq. ft. flat roof top. 1st coat coverage was approx. 200-300 sq. ft. 2nd coat approx. 400-600 sq ft . Helping to extend my roof life until I`m ready to drop the 12K for a new roof. Inside of home cooler and roof top temp. is equal to outside temp were as before I used the product roof was scorching hot!. Would I recommend the product YES! Living in Miami a white cool roof is a must have. Good Luck April 1, 2016
Rated 5.0 out of 5.0 by I Love it... Excellent product, no primer need, dry quickly and seal strong. I used in my mobile home metal roof that was leaking bad from few cracks and worked perfect. August 29, 2012
Rated 1.0 out of 5.0 by Junk, will completely wash off in less than a year, will only fix leaks temporarily it is not 100% silicone, this product will not last. September 28, 2015
Rated 1.0 out of 5.0 by roof sealer creates roof leak, Beware i applied two coats of this product less than a year ago, to a slightly sloping metal roof on a florida sunroom. the roof was in good condition. It had never leaked and I had only hoped to reduce the inside temperature. After a very messy application, the temperature seems to have been slightly reduced, but now the roof leaks... in several places along the join to the house and window walls. i called the lanco tech support, who told me that can happen because where the product was applied, the roof will contract and expand at a different rate. ..ie creating leaks! and apparantly the 10 year warranty doesn't cover this! The product wasn't expensive for what it promised, but that plus paying someone to install it... and now paying for repairs. ..it turns out to have been a very expensive job. Although the room may now be a few degrees cooler (hard to really document this), I cannot reconcile this with a leaking roof. very disappointing product... buyer beware. July 20, 2015
Rated 5.0 out of 5.0 by Great product Great product, cooler, worth every penny, easy to use April 3, 2015
Rated 3.0 out of 5.0 by Lanco White-Seal I have used the product before and it is a good product. But the dry time is inacurate. The add states 1-2 hr dry time. I gave it over 6 hrs to dry and it washed off with the rain. Wasted over 7 gallons of paint. It only drys quick if its in direct sun at the heat of the day. If it is done when its cool, 75-80 as the sun goes down and the roof cools it doesnt dry quick at all. June 25, 2014
Rated 5.0 out of 5.0 by Simply put, it works and works well My shingles were in bad shape, 20 years old and getting to show their age. I even had some severe hail damage and a couple of leaks that evaded my best efforts to stop. I researched and decided to give this product a try. It was spend $15,000 for a new roof or go a much cheaper route. I was still a little reluctant because of my age, 66, and also a bad back. I'm a stubborn old man so I decided to just do it. I was going to do the back part of my house first, the part with the leaks. I went with this 10 year product, thinking if it worked as stated I would just put another coat on in a few years and forgo the more expensive 15 year guarantee product. Due to my age and back problem I spent just a few hours each day and tried to pick days where there was some cloud cover but no rain expected. I used a 3/4 nap roller and poured half of the bucket of product into another 5 gallon bucket. This made it easy to lift up to the roof, using a heavy rope to lift it up. You need to take your time and load up the product on your roller for the first coat. Just put your roller into the bucket, with the long screw on handle attached, pull out and start applying. Make sure you take your time and don't skimp on product for the first coat. Fill in all of those cracks and any hail damage. The first coat is the hardest to apply and uses a lot of product, it takes time but just be patient. The second coat is a breeze and goes on fast and easy, the surface is smoother, you use a lot less product. Wait at least a day before putting on the second coat. Take your time and do a good job. Here is a suggestion for keeping you bucket of product at an even level and SECURE on a slopped roof. I used a concrete landscape brick. The ones that are about two feet long and a few inches thick. I used HALF of one and put the bottom edge of the bucket on it and the top part of the bucket would be level at the top where it made contact with the roof. This made the bucket more secure and easy to move around. In conclusion, now I have a beautiful roof that is reducing my power bills and NO MORE LEAKS. It sure beats paying someone thousands for what you can do yourself. I'll probably hire someone to put on another coat a few years from now. I don't want to push my luck at age 70. January 24, 2015
