Warranty coverage
A leaking barn roof costs more than the barn.
The problem
Most barn roofs are aging metal panels held down by hundreds of fasteners — and every screw is a future leak. Gaskets dry out, laps rust, and water drips on hay, livestock, tack, and machinery worth far more than the building. Replacing a big ag roof runs tens of thousands of dollars.
The Crazy Seal fix
Crazy Seal goes right over your existing metal — rust treated, screws and laps sealed — under one seamless, fiber-infused silicone membrane. A fraction of the cost of re-roofing, installed yourself, with a bright white finish that keeps the barn cooler all summer.
Crazy Seal is perfect for:
- Metal panel roofs with leaking screws and rusted laps
- Hay lofts, stables, and equipment storage that must stay dry
- Large roofs on a budget — no tear-off, no crew required
- Pole barns, gambrel barns, loafing sheds, and lean-tos
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
