BEFOREAFTER
BEFOREAFTERA seamless, fiber-infused silicone membrane for tractor trailers, box trucks, and delivery vehicles — built for the constant flexing that vibrates ordinary sealant apart. One crew can seal a unit in a day, in your own yard.
A fire department sealed a 24' rescue trailer for about $1,000 in product instead of a $40,000 replacement. Sealing a fleet? Talk to us about volume.
Sized & priced to your exact roof
From a single tube of caulk to a complete system for thousands of square feet. A 24' trailer runs about $1,200 in product — versus writing off the unit over a roof.

David Vincent from Key Largo, FL
“THANK YOU for a great and reassuring experience! I have already referred this system to 3 family and friends. I'm looking forward to a very long, assured feeling of protection from water intrusion.”
Philip Posey from Tuscumbia, AL
“We could not be more pleased with the Crazy Seal product. We are expecting to have many years of enjoyment from our sunroom now that we do not have to worry about leaks.”
Douglas Evans from Overton, NV
“After viewing the DIY videos 4 times, I followed the instructions to the letter. The product went on easily.”
Dennis Van Dusseldorp
“Great product, went on like advertised and ended up with a great looking roof that will last a long time.”

How It Goes Down
No special tools. Three steps, guided by step-by-step videos.
1. Clean
Wash the roof with Crazy Clean so the membrane bonds to the roof — not the dirt.
2. Seal
Caulk and patch every seam, screw, and penetration with Crazy Caulk and Crazy Patch.
3. Coat
Roll on the seamless Crazy Seal membrane and never worry about that roof again.
