Expert Verdict — Reviewed by the SuperArbor Pro Desk
Roof-Fast SA Cap is a good choice for low-slope residential roofs and porches where torching or hot asphalt is impractical. Plan laps and substrate priming per IKO instructions, and roll the membrane firmly to seat the adhesive. Match cap color to shingles or trim, and use the matching Roof-Fast Base for two-ply assemblies.
Self-adhering membranes are very slippery, especially with dust or moisture, so wear proper footwear and fall protection when walking on or installing the membrane.
Choose IKO Roof-Fast SA Cap Membrane in your color for a clean, peel-and-stick low-slope roofing system.
