The PermaBest Process | Prepare, Clean, Treat, PermaBest
PermaBest's 4-step process — Prepare, Clean, Treat, PermaBest — restores most existing roofs without tear-off using a spray-applied universal liquid membrane.
The PermaBest Process: Quick Answers
- The PermaBest process has four steps: Prepare the roof, Clean the surface, Treat problem areas and details, then spray-apply the PermaBest membrane.
- PermaBest is the only overcoat that can revive most existing roofs without a tear-off, eliminating demolition costs, business disruption, and landfill waste.
- PermaBest is spray-applied as a liquid, so it perfectly conforms to every curb, penetration, and fastener before curing into one monolithic membrane.
- PermaBest bonds directly to concrete, metal, asphalt, and sheet membranes — one universal liquid membrane that can do it all.
- Because installation is spray-applied over the existing roof, a PermaBest restoration is faster and less disruptive than tear-off replacement.
Frequently Asked Questions
How is PermaBest applied to a roof?
PermaBest follows a four-step process: Prepare, Clean, Treat, PermaBest. The roof is prepared and cleaned, problem areas and details are treated with primers and FiberSeal Caulk, then the liquid membrane is spray-applied over the entire surface.
Does PermaBest require removing the existing roof?
No. PermaBest is the only overcoat that can revive most existing roofs without tear-off. The existing roof becomes the substrate, which saves demolition cost and keeps the old roof out of the landfill.
What surfaces does PermaBest bond to during installation?
PermaBest bonds to concrete, metal, asphalt, and sheet membranes including TPO, PVC, EPDM, and Hypalon. The only exceptions are silicone and Teflon-based finishes such as Hylar and Kynar.
Why is spray application better than rolled or taped systems?
Spray-applied liquid conforms perfectly to every roof detail — seams, fasteners, curbs, and penetrations — then cures into a single monolithic membrane. Rolled and taped systems leave overlaps and edges, which is where roughly 90% of leaks start.
Can my building stay open during a PermaBest installation?
Yes, in most cases. Because there is no tear-off, PermaBest installation is far less disruptive than roof replacement — no demolition debris, no exposed deck, and no interruption to normal building operations.
