Expert Verdict — Reviewed by the SuperArbor Pro Desk
Non-reinforced 60 mil EPDM is the workhorse for standard low-slope roofs; choose pre-taped variants to cut seam labor on larger decks. Wider 20 ft rolls reduce the number of seams per square. For high-traffic or hail-prone roofs, consider reinforced EPDM instead.
Follow the manufacturer's installation instructions and local building codes, and use proper fall protection when working on low-slope roofs.
Order the Johns Manville 60 mil non-reinforced EPDM membrane roll in the size and tape option you need.
