Why Choose A+ Roofing Supply’s Synthetic Roofing Underlayment?

🧱 Built Tough for Real Job Sites
Made with a high-strength, tear-resistant synthetic material that won’t absorb water, dry out, crack, or leak oils like old-school asphalt felts.

🌬️ Double Duty Weather Defense
Acts as a secondary moisture barrier, helping stop wind-driven rain from sneaking under your shingles—offering protection when your home needs it most.

🌡️ Cooler to Work On
The light gray surface stays up to 30°F cooler than typical black felts, making installation safer and more comfortable on hot days. (Based on A+ internal testing vs. standard asphalt felts on 90°F days.)

🧰 Lightweight & Easy to Handle
Each roll covers 10 squares (1000 sq.ft.) and is 48 inches wide—wider and lighter than standard felt rolls—making it easier to transport, unroll, and install.

🏗️ A Flatter, Cleaner Finish
No more wrinkles or uneven surfaces. Our underlayment lies flatter and eliminates “telegraphing” through shingles, for a better-looking final result.
