Warranty coverage
A metal roof is a grid of future leaks.
The problem
Steel buildings are held down by thousands of screws, each with a rubber washer that has an expiration date. Daily expansion backs screws out and works lap seams open — and once rust starts at the laps, patch coatings become an annual ritual that never ends.
The Crazy Seal fix
Crazy Seal treats the roof as one system: rust neutralized, every fastener head and lap seam sealed with our 3-part process, and the whole surface locked under a seamless fiber-infused silicone membrane. The reflective finish drops roof temperatures dramatically — and it shows on the cooling bill.
Crazy Seal is perfect for:
- Screw-down metal roofs with aging washer gaskets
- Rust at lap seams, ridge caps, and penetrations
- Shops, hangars, and steel buildings of any footprint
- Cutting summer heat gain with a reflective white finish
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

“I am an independent contractor and this stuff is different (in a good way) than anything I have ever used. I could tell by how well it adhered that it is very strong and flexible. Very impressed so far.”

“Very satisfied. Best product ever! Would recommend it to anyone looking to be "Once & Done"”
Brian Mitchell
“Pretty easy install. Followed the directions exactly as prescribed and looks great. Water beads up on the roof and just sheets off now. Very satisfied with how easy it was.”
David Hutchins
“Very happy with the product and the customer service is second to none. All the work is in the prep. Take your time with that and everything will go well.”
