Certainteed RoofRunner Synthetic Roofing Underlayment, 10 Square Roll, Gray
CertainTeed RoofRunner is a synthetic steep-slope roofing underlayment supplied in a 10 square roll in gray. It installs beneath asphalt shingles as a secondary water-shedding layer over the roof deck. One roll is the sell unit, so a single roll covers 1,000 square feet of deck area.
Key Features:

- Synthetic construction: Synthetic underlayment is a lighter, tear-resistant alternative to felt.
- Gray surface: Gray top surface for a clean look during installation.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Order one roll per 10 squares of deck and add a roll for laps and valley waste on cut-up roofs. Synthetic underlayment can be exposed briefly during construction, but follow the printed exposure limits. Pair RoofRunner with starter shingle and a matching shingle system for a complete dry-in.
Synthetic underlayment is slippery, especially when wet or dusty; wear proper footwear and fall protection while installing.
