Synthetic Underlayment

Synthetic underlayment protects the roof deck long after the panels go on.

High-Performance Synthetic Roof Underlayment

Synthetic underlayment sits directly on the roof deck beneath the panels, shedding wind-driven rain, guarding against condensation, and protecting the deck during construction. It has largely replaced traditional felt because it is lighter, stronger, and built to last as long as the roof above it. ACR carries synthetic underlayment for agricultural, commercial, and residential projects. Select a manufacturer below to view their lineup.
