BEFOREAFTER
BEFOREAFTERA seamless, fiber-infused silicone system your own crew — or any local contractor — installs over the existing roof, in stages, as budget allows. Every repair chemically bonds to the last until the whole roof is one permanent membrane.
99% of commercial kits are custom built by a professional or a specialist on our team. Tell us about your roof and we'll spec it with you — or run your square footage through the Kit Builder for a quick estimate.
Sized & priced to your exact roof
From a single tube of caulk to a complete system for thousands of square feet. Most commercial projects are custom quoted — staged installs let you spread the cost across budget years.

ResidentialProject #5344
DIY Residential Roof That Sealed the Deal
“The product was easy to apply, and the customer service was fantastic.”
ResidentialProject #5210
Slippery Coats and Solid Results
“The first coating was challenging, the second coating was easier and slippery. By the time we got to the end and finishing up, we were slipping and sliding. It was an experience to hang on to.”
ResidentialProject #5113
Commercial Roof Revived with a Seamless Overlay
“Very easy to install.”
Straight From the Roof
Real reviews from customers who installed it themselves.

Melvin Nixon
“I am an independent contractor and this stuff is different (in a good way) than anything I have ever used. I could tell by how well it adhered that it is very strong and flexible. Very impressed so far.”

Robert Davies
“Very satisfied. Best product ever! Would recommend it to anyone looking to be "Once & Done"”

Brian Mitchell
“Pretty easy install. Followed the directions exactly as prescribed and looks great. Water beads up on the roof and just sheets off now. Very satisfied with how easy it was.”

David Hutchins
“Very happy with the product and the customer service is second to none. All the work is in the prep. Take your time with that and everything will go well.”

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.
