Click to Watch the System Overview (5:15)
The hardest 100 square feet on your house.
Porch roofs are small, but they combine everything roofing hates: a low slope that drains slowly, a flashing joint where the porch meets the house wall, and roll roofing or metal panels near the end of their life. That wall junction is where the water gets in — and it stains your porch ceiling, rots the framing, and defies every tube of caulk you've thrown at it.
Crazy Seal solves the junction problem by eliminating the junction: our 3-part system seals the flashing, the seams, and the field into one continuous membrane that runs up the wall line. A porch is a one-weekend project with our smallest kit, and it comes with the same 50 year warranty as a whole commercial roof.
Crazy Seal is perfect for:
- Recurring leaks at the porch-to-wall flashing line
- Low-slope roofs over porches, stoops, and entryways
- Roll roofing and metal panels past their prime
- Small kits sized right — no leftover pallet of material
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.
