GAF Grand Canyon

What This Service Involves

Grand Canyon sits at the top of GAF's designer range, using extra layers and oversized tabs to create dramatic depth and shadow. The result is a rugged, rustic roof that recalls thick hand-cut wood shakes on a grand scale. It suits large, architecturally significant Northwest homes where the roof is a defining feature. The heavyweight construction and algae-resistant granules perform well in our damp, moss-friendly environment. For homeowners who want maximum texture and presence, few asphalt shingles make a bolder statement.

Benefits

One of the thickest, most dramatic designer profiles available; Bold mountain-lodge character for large PNW homes; Heavyweight build with deep, rugged shadow lines; Algae-resistant granules for our moss-prone climate; Standout curb appeal that anchors prominent architecture

Our Process

1) Remove old roofing and evaluate the deck for structural capacity and moisture; 2) Install ice-and-water shield and synthetic underlayment at key areas; 3) Lay the heavyweight, oversized shingles with careful staggering for depth; 4) Finish ridges and detail all flashings for a sealed, weather-tight roof

What Affects the Cost

Roof size, pitch, and structural considerations for the heavy shingle; Top-tier designer shingles carry premium material cost; Extra labor for oversized, heavyweight installation; Deck repairs found at tear-off; Selected color blend and underlayment upgrades

Best Time of Year

Grand Canyon installs year-round locally, with warm, dry summer weather ideal for handling and sealing the heavy shingles.
