Warranty coverage
Water below, weather above — boat house roofs get it from both sides.
The problem
A boat house roof never dries out. Humidity rises off the water 24/7, UV reflects up and doubles the sun exposure, and the structure is usually built light — while the boat underneath is often the most valuable thing on the property.
The Crazy Seal fix
Crazy Seal is 94% silicone — a material that simply doesn't care about water. The fiber-infused membrane seals seams, fasteners, and flashing into one continuous waterproof layer that shrugs off moisture from both directions and relentless reflected UV.
Crazy Seal is perfect for:
- Metal and low-slope roofs in permanent high humidity
- Double UV exposure from sunlight reflecting off the water
- Protecting boats and lifts worth more than the structure
- Docks, lake cabins, and covered slips with aging roofs
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
