Expert Verdict — Reviewed by the SuperArbor Pro Desk
Resistor is a good pick when crews want a lighter, slip-resistant synthetic under eaves and valleys with some schedule flexibility thanks to 90-day UV resistance. Roll it horizontally with proper laps and fasten per the manufacturer's pattern in high-wind areas. For jobs needing longer exposure or ice-dam eave membranes, verify those requirements against this product's data before substituting.
Even with an anti-slip facer, use fall protection and appropriate footwear when working on sloped roofs.
