Metal Building Roofs
Every screw head sealed. Every lap seam closed. Permanently.
Click to Watch the System Overview (5:15)
A metal roof is a grid of future leaks.
Steel buildings are fastened down with thousands of screws, and every one has a rubber washer with an expiration date. Panels expand and contract daily, backing screws out and working lap seams open. Once rust starts at the laps, patch coatings and washer swaps become an annual ritual that never actually ends.
Crazy Seal treats the whole roof as one system: rust is neutralized, every fastener head and lap seam gets sealed with our 3-part process, and the entire surface is locked under a seamless fiber-infused silicone membrane. As a bonus, the highly reflective finish drops roof surface temperatures dramatically — which shows up 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?
The Crazy Seal Roofing System is a fluid applied, seamless roofing system designed to permanently seal flat and low-slope roofs. Our 3-part system eliminates your problem areas first, then locks the entire roof under a seamless, fiber-infused silicone membrane — the only one on the market strengthened with polyethylene fibers, like rebar in concrete.
Crazy Seal takes the complex world of roofing and simplifies it so it can be installed by just about anyone, backed by our 50 year warranty and a support team that answers the phone.
