WeatherMaster® Ice & Water Underlayment is a composite roof underlayment designed to provide a secondary waterproofing barrier needed to prevent ice dams and damage from wind-blown rain.

A proprietary fiberglass mat reinforced, SBS-modified asphalt makes WeatherMaster® Ice & Water Underlayment ideally suited for continuous waterproofing protection against ice dams and wind-blown rain year after year. The self-adhesive underlayment creates a watertight barrier by sealing to the roof deck and around nails. WeatherMaster® Ice & Water Underlayment provides excellent traction and protection from UV degradation and weathering thanks to its granular surface.

WeatherMaster® Ice & Water 200 Underlayment Benefits:

* UV Protected Surface – 45 Day Exposure

* High-Temperature Stability – 240°F

* Self-Adhesive Backing Seals Directly to the Deck

* Dual Modified Asphalt Provides Superior Granule Adhesion

* Aggressive Bond at Low Temperatures

* SBS-Modified Asphalt Coating Helps Seal Around Nails for a Watertight Result

* Fiberglass Mat Is Stronger and Provides Better Tear Resistance Than Saturated Felt Underlayment

Pro-Cut® HP42® starter shingles protect the roof edge and provide anchoring power for high wind resistance at the critical eave and rake areas. They protect the roof by filling in spaces under the cut-outs and edges for the first course of exposed shingles, preventing wind uplift.

Proper attic ventilation is essential for roof performance and home efficiency. Without proper ventilation a roofs lifespan can be cut down dramatically. That’s why we install the Atlas TruRidge® All-Weather Exhaust Vent—a low-profile ridge vent designed to work year-round in any climate. Key Benefits:

Allows hot, humid air to escape from your attic

Helps prevent mold, moisture damage, and ice dams

Low-profile design blends seamlessly with your roofline

Durable, weather-resistant construction

Fully compatible with the Atlas Signature Select® Warranty

Ventilation isn’t optional—it’s part of a complete roofing system. TruRidge® keeps your attic breathing, your roof protected, and your home more energy-efficient.

IMPORTANT: Proper attic ventilation requires a balanced system—which is why we always evaluate your intake ventilation during every roof inspection. Without adequate intake (typically through soffit vents), even the best exhaust vent can’t do its job. A complete roofing system means making sure air flows in and out properly, protecting your roof from the inside out.

Peak Performance. Protected Beauty. Pro-Cut® Hip & Ridge shingles featuring Scotchgard™ Protector help resist black streaks caused by algae, while providing a finish designer look at the hip and ridge.
