Expert Verdict — Reviewed by the SuperArbor Pro Desk
PlyStiK SA-250 HT is a heavy-duty peel-and-stick choice when you want ice-dam protection and a robust secondary water barrier under shingles, tile, shakes or metal. Its fiberglass reinforcement and SBS modified bitumen give it more strength than sanded or granular asphalt-based peel-and-stick alternatives it was designed to replace. Plan laps carefully to calculate roll counts, and finish the roof within the 6-month UV exposure window.
Install from secure footing on properly braced decks and follow manufacturer application instructions, as walking on hot, smooth membranes can be slippery.
Order Epilay PlyStiK SA-250 HT underlayment for premium peel-and-stick protection on your next sloped roof.
