The Details That Matter
Why This Kit Works
40 mils of cured membrane. The first layer cures to 20 mils; the second doubles it to 40 — even thicker where Crazy Caulk and Crazy Patch seal seams and penetrations.
100 sq ft per gallon. Kits are calculated by square footage, so the kit sized to your roof has exactly what it needs.
Built for imperfect installers. We recommend the double layer in most instances — the second coat guarantees proper coverage everywhere.
You never install alone. Step-by-step video suite, installation PDFs, and in-house project specialists standing by.
50-year no-hassle warranty. Finish the install, fill out a simple form, and your roof is covered.

Slippery Coats and Solid Results
“The first coating was challenging, the second coating was easier and slippery. By the time we got to the end and finishing up, we were slipping and sliding. It was an experience to hang on to.”
Straight From the Roof
Real reviews from customers who installed it themselves.
“THANK YOU for a great and reassuring experience! I have already referred this system to 3 family and friends. I'm looking forward to a very long, assured feeling of protection from water intrusion.”
David Vincent from Key Largo, FL
“We could not be more pleased with the Crazy Seal product. We are expecting to have many years of enjoyment from our sunroom now that we do not have to worry about leaks.”
Philip Posey from Tuscumbia, AL
“After viewing the DIY videos 4 times, I followed the instructions to the letter. The product went on easily.”
Douglas Evans from Overton, NV
“Great product, went on like advertised and ended up with a great looking roof that will last a long time.”

How It Goes Down
No torches, no tear-off, no special tools. Three steps, guided by step-by-step videos.
1. Clean
Wash the roof with Crazy Clean so the membrane bonds to the roof — not the dirt.
2. Seal
Caulk and patch every seam, screw, and penetration with Crazy Caulk and Crazy Patch.
3. Coat
Roll on the seamless Crazy Seal membrane and never worry about that roof again.
