Rated 5.0 out of 5.0 by j2skincare 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.

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.

Rated 1.0 out of 5.0 by Makesumwake 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.

Rated 1.0 out of 5.0 by dutch 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.

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.
