Asked by: Wes
Absolutely, and with anything, well anything that has some flex to it. Just make sure it's not only dry, but cured. They say recoat after 24 hours, to be safe, give it a few more days.

This product reduced the inside temperature 12-17 degrees on the inside of my home. It was applied over 17 year old shingles. I'm very pleased and quite impressed. It helped cut my electric bill in half and my ac doesn't run 24/7. In Florida, this product is a must. Highly recommend it.!!!!

There are better products out there, but not for 14$ a gallon. I used this on my old and worn out asphalt shingle roof to give it another 10 years without the labor and cost of replacing (yes I'm cheap). 2 coats and I'm happy- it's doing what I wanted it to do- 'hold' the shingles down, reflect the heat, and provide water proofing. After a light chlorine rinse, I rolled the first on at 65 square feet a gallon- don't think it can be rolled on any heavier. After dipping and rolling and getting nowhere, I started pouring it and then rolling it out- much faster and easier. Used an inch and a quarter roller which was shot after the first coat. 2nd coat at 115 sq. ft per and no dry rolling. I thinned down the 2nd coat by adding a half gallon of a tinted paint to each 5- I thought a bright white shingle roof would be too 'redneck' for my neighborhood. It's the only way to tint this product, and kind of difficult to get the buckets to match. A little tint goes a long way with elastomerics, and with a half in. drill and a paddle it went quick. So for about 1000 bucks and and some elbow grease I've got my new roof.
