The Details That Matter
Why It Works
Fiber-infused silicone mastic. Moisture-curing with excellent adhesion to most surfaces.
Seals every penetration. Wherever sealant was previously applied on your roof, Crazy Patch goes down to seal it for good.
Part of one seamless system. The Crazy Seal membrane bonds directly over it — extra thickness exactly where roofs leak first.

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.
