#1 Top Best Highest Quality Roof Sealer
The best ever roof sealer. Our commercial roof has leaked for 18 years.We tried 1 can and were very impressed with the thickness and adhesion.We have now ordered many cans of this and have 85 % finished patching our roof. Even so, after 3-4" of rain in the last 3 days, we are 100% bone dry with zero leaks.This stuff really works.

Amazing product that actually works!!
We have tried nearly every type of roof caulking out there. The Texas summers on a metal roof are brutal. This and the paint are the only thing that have held up. They flex and still seal where 2 pieces of metal contact where we have had a roof leak for years... no more leak. It set solid in 48 hours. Application was really easy and forgiving. We put on 3 layers of the paint on the tape just to be safe which surprisingly didn't take very much to do. No running or bubbling found. Even after 120 degree Texas days making the roof well over 150... and it still held. No cracking, running.. nothing. It is our go to now. Well worth the money and the only roof sealant that still seems to work. Mineral oil to clean the brush, easy to apply - just like a thick paint. Dries in 24-48 hours. 3 layers with the tape was enough to handle 7 inches of rain in 3 hours no leaks this spring. Thank you for making this and please keep selling it!

Worth the money!
Had never used this type of product but have to say it worked wonders!Was used on a metal roof that had been battered by repeated recent storms and was the fastestway I could think of to stop the leaks without replacing the roof on the building.Only had about 36 hours between storms and it stopped all leaks.5 Stars!!

This Stuff Works
My boat is permanently stored in a very old boat house that has a sagging metal roof where water pools in a few low points. The roof was leaking though seams and screw holes on the metal roof and dripping water all over everything. After applying this sealant to all the screws and seams I have not had any leaks for 9 months. I live the NW US where we get a lot of wet snow and rain, this stuff really works.

Waterproofer that works
Excellent product for sealing seams on your roof or waterproofing wonder board or Sheetrock seams for ceilings. Goes on black and smooth and a gallon goes a long way. Flex Seal is trash compared to this. Awesome product. Sealed all my leak seams.

Does not adhere to wood very well
Bought twice, second one arrived with broken lid and leakage inside shipping box. Used on pressure treated fence posts but product doesn’t adhere, tends to peel if you are not real careful how you handle it
