GAF shingles — America's most-installed roof, installed right.

Why Timberline Became the Default American Roof

Scale, mostly — and consistency. GAF is North America's largest roofing manufacturer, which means Timberline shingles are available everywhere, color-matched batch to batch, and easy to source a bundle of in ten years when a branch takes out one slope. The shingle itself earns the volume: solid wind ratings, algae-protected granules, and a laminated profile that looks right on nearly any house.

For homeowners, that ubiquity has a practical payoff at resale: appraisers and inspectors know exactly what a Timberline roof is and what it's worth.

The Warranty, Without the Fine-Print Fog

GAF backs its architectural shingles with a lifetime limited warranty for the original owner, and enhanced coverage tiers exist when a full GAF accessory system is installed. The honest key to all of it: installation to GAF's published requirements — nailing pattern, starter courses, ridge products, ventilation. That's how we install — so your new roof carries the full manufacturer warranty.
