The Details That Matter

Why It Works

  • Fiber-infused silicone sealant. Moisture-curing with excellent adhesion to most surfaces.

  • About 50 feet per tube. Running a quarter-inch bead — and a one-gallon container equals about eight tubes.

  • Built for seams. The seams along the sides of an RV, gutter attachments — anywhere components meet the roof.

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.

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.

After viewing the DIY videos 4 times, I followed the instructions to the letter. The product went on easily.

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.
