Warranty coverage
No RV roof works harder than a truck camper roof.
The problem
A truck camper rides on the truck frame, so its roof twists with every pothole and driveway. Rigid sealants and aging rubber crack right where that movement concentrates — the cab-over nose seam and around vents, fans, and antenna mounts.
The Crazy Seal fix
Crazy Seal stays permanently flexible, bonds to aluminum, fiberglass, TPO, and EPDM, and covers the whole roof — seams, penetrations, and all — in one continuous layer. Do it once and stop chasing leaks every season.
Crazy Seal is perfect for:
- Cab-over seam leaks that reappear after every re-caulk
- Aluminum and fiberglass roofs with dozens of penetrations
- Compact roofs — one small kit covers most truck campers
- Full-timers and overlanders who cannot afford water damage
What is Crazy Seal?
A fluid-applied, seamless roofing system that permanently seals flat and low-slope roofs — the only membrane on the market strengthened with polyethylene fibers, like rebar in concrete.
- 3-part system: problem areas sealed first, then one seamless membrane
- Simple enough for just about anyone to install
- Backed by our 50 year warranty
- A support team that answers the phone
