GAF Timberline HDZ RS colors
The 7 colors GAF lists for Timberline HDZ RS. 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. Seven blends; GAF's cool-roof (CRRC) ratings are per colour, so check the one you pick if you need it for code.

What a GAF Timberline HDZ RS 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 HDZ RS costs your roofer depends on their supplier, so ask for it by name. Prices in your state: roof replacement cost by state.
