Expert Verdict — Reviewed by the SuperArbor Pro Desk
Self-adhered SBS base ply shines on detail work, temporary roofs and projects where torching is restricted. Roll it firmly from center out to chase air, keep laps tight using the selvage edge, and prime questionable substrates if the system specification calls for it. Order an extra roll for laps and waste on odd-shaped roofs.
Self-adhered membranes require clean, dry substrates and proper personal protective equipment; inspect the deck for moisture before adhering any membrane.
