Expert Verdict Reviewed by the SuperArbor Pro Desk

Choose the 6 oz. cushioning layer over the 3 oz. separation layer where a recover goes over an existing mod-bit roof or other rough substrate, since the heavier mat better isolates the new membrane. It is a fast, economical alternative to tearing off, particularly around penetrations and rooftop units. Keep laps at least 6 in., lay it flat without wrinkles, and place ballast promptly when used in ballasted systems. Always follow the EverGuard TPO/PVC system design tables so the assembly remains within spec.

Heavy 125 lb rolls require two-person handling or mechanical lifting on the roof, and installers should follow fall protection requirements per OSHA and the manufacturer’s installation instructions.
