Expert Verdict — Reviewed by the SuperArbor Pro Desk
A low-filler base sheet like this pays off in cold weather and in the mop or torch sequence, because it stays more flexible and lies flatter over deck irregularities. Verify the attachment method - nail pattern or adhesive - against the specified Elevate system before ordering, since the base ply controls wind resistance of the whole assembly. Order about 10 percent extra for laps, starters and patches.
Base sheets are used beneath hot asphalt, torch or adhesive systems; follow fire-safety and manufacturer application requirements for the roofing system used.
