Sunroom roofs leak by design.
Most sunrooms and patio enclosures are capped with aluminum pan roofs — long interlocking panels whose seams rely on factory sealant that dries out in a decade. When those seams open up, water lands on drywall, carpet, and furniture in what is effectively part of your house. Re-caulking the seams buys a season or two at best.
Crazy Seal is the permanent answer: our 3-part system fills and bridges every seam, seals the wall tie-in, and covers the entire pan roof with one seamless fiber-infused membrane. The before-and-after photos below are an actual sunroom install — slide the bar and see exactly what your roof would get.
Crazy Seal is perfect for:
- Aluminum pan roofs with failing seam sealant
- Finished living space directly under the roof
- Wall tie-ins and gutter edges that re-caulking never fixes
- Patio enclosures, Florida rooms, and screen room conversions
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.
