Industrial Crazy Tape is used for unlimited sealing applications. It has a strong adhesive on one side. This gives you the ability to add additional structural integrity to a seam with sealing capabilities.

The Details That Matter
Why It Works
50 feet per roll. Heavy-duty length for long seam runs on industrial-scale roofs.
Adhesive one side, fabric the other. Instant hold underneath, and a surface the Crazy Seal membrane bonds directly to on top.
Made for wood decking. Creates a seal over seams where the system is applied direct to deck.
Hybrid transitions. Bridge the membrane from existing roofing material onto wood decking in one repair.

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.”

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.
