GAF Timberline UHDZ colors
The 6 colors GAF lists for Timberline UHDZ. The swatches are our own drawings, an impression of each color's tone, not a photo or a color match: granule blends look different in sun, shade and on a whole roof. Look at a real sample board, and a house near you with the color on it, before you choose. Sold as a single six-colour collection; GAF does not mark any colour as regional.

What a GAF Timberline UHDZ roof costs
Our quote engine's price for a roof of architectural shingles at a 6/12 pitch, old layer torn off, at US-average roofer wages. The roof is bigger than the house: the pitch adds about 12% to the footprint.
| House footprint | Roof | Installed |
|---|---|---|
| 1,500 sq ft | 16.8 squares | $9,500–$10,900 |
| 2,000 sq ft | 22.4 squares | $12,400–$14,300 |
| 2,500 sq ft | 28.0 squares | $15,400–$17,700 |
The engine prices architectural shingles as one class, not by brand, so these figures are the same on every line of that class we cover. Within the class, roof size, pitch, tear-off and local labour move a price far more than the label on the bundle; what Timberline UHDZ costs your roofer depends on their supplier, so ask for it by name. Prices in your state: roof replacement cost by state.

GAF Timberline UHDZ questions
How much does a GAF Timberline UHDZ roof cost?
On our quote engine a roof of architectural shingles on a 2,000 sq ft house (6/12 pitch, old layer torn off) comes to about $12,400–$14,300 at US-average roofer wages, roughly $600 per square installed. The engine prices architectural shingles as one class, not by brand: a roofer's price for Timberline UHDZ depends on what their supplier charges them for it, so ask for it by name.
What colors does GAF Timberline UHDZ come in?
GAF lists 6 colors: Pewter Gray, Barkwood, Charcoal, Shakewood, Slate, Weathered Wood. Availability varies by region, so check with a local roofer or GAF before you settle on one.
Is GAF Timberline UHDZ impact resistant?
GAF lists it as UL 2218 Class 4 (only packages marked with the UltraMat logo and Class 4 statement). Class 4 is the highest UL 2218 rating and the one many insurers discount premiums for; Class 3 is one step below.
What wind speed is GAF Timberline UHDZ rated for?
No maximum wind speed (15-year WindProven warranty) with GAF starter strip, ridge caps, roof deck protection and leak barrier or attic ventilation, per GAF's own pages. Higher wind warranties usually need extra nails per shingle and the manufacturer's starter and ridge shingles.
What warranty does GAF Timberline UHDZ have?
Lifetime limited warranty (shingles; as long as the original owner of a single-family home owns it), with Smart Choice Protection, 10 years, with a GAF Roofing System (shingles plus 3 qualifying accessories). After the non-prorated period, a manufacturer's warranty usually covers a shrinking share of material cost and rarely labour; see our shingle warranty guide.
