Secure Start® SG Underlayment

Our Smooth Grade Underlayment

Secure Start® SG (smooth grade) is a lightweight, synthetic underlayment providing a layer of moisture protection over the entire roof, and suitable for use with asphalt shingles, roof tile, and metal.

Its smooth surfaces, top and bottom, lessen shingle drag and increase installation speed.

Underlayment for Shingle Roofs

A new roof requires more than just shingles. It’s a cohesive, coordinated system of 5 parts: 1) ice & water barrier, 2) underlayment, 3) starter shingles, 4) field (roofing) shingles, and 5) hip & ridge shingles.

As the name implies, underlayment sits under the shingle and provides a vapor barrier covering the entire roof.
