What does a GAF Grand Sequoia roof look like?
It reads like wood shake from the street. Grand Sequoia is GAF’s big, sculpted designer profile: a thicker laminate than GAF Timberline HDZ, with a heavier shadow line across the field. That look suits larger custom homes where the roof is a major part of the design, which is why it turns up on mountain houses with long, open roof planes. Colors that go on roofs around here run to Hickory, Pewter Grey, Weatheredwood and Storm Grey. The asphalt shingle roofing page puts the GAF lines side by side, and the Idaho roofing materials guide covers what goes under them.
What does a Grand Sequoia roof cost?
More per square than GAF Timberline HDZ, and less than a standing seam metal roof. Shingle thickness and weight set that gap. The rest of the price comes from the size of the roof, its pitch, how many layers come off and how much decking has to be replaced. The roof replacement cost guide walks through each driver.
What a mountain roof asks for
A heavy shingle is the part you see. What keeps a Donnelly roof dry is underneath it: ice and water barrier run wide at the eaves and up the valleys, flashing cut for a long winter, and an attic that breathes well enough to keep the deck one temperature. Snow sits longer up here than it does on the valley floor, so those details get more attention on a mountain house, not less. The roof replacement page takes the whole build apart, layer by layer.
