Expert Verdict — Reviewed by the SuperArbor Pro Desk
Forty-five mil is the workhorse TPO gauge for many commercial re-roofs and new construction where the specification allows. The 6 ft width is useful on narrow sections, around penetrations and for cut-up areas where a 10 ft roll is cumbersome. Keep membrane, adhesives and flashing from the same JM system and follow the printed fastening patterns for the selected attachment method.
Rooftop membrane installation requires fall protection, proper roll handling for a 171 lb product, and adherence to manufacturer instructions and local building codes.
Order the Johns Manville 45 mil White 6 ft x 100 ft TPO membrane roll for your JM TPO roofing system.
