How do you pick a GAF Timberline UHDZ shingle color?
Short answer. Start from your home's fixed colors, the brick, stone and siding, and pick from UHDZ's six colors: Charcoal or Pewter Gray for cool palettes, Barkwood or Shakewood for warm ones, and Weathered Wood or Slate when you want a blend. Because UHDZ's dual shadow line deepens every color, judge only on full-size UHDZ shingles viewed outdoors.
Step 1: classify your exterior
Is your house cool (white, gray, blue, black trim), warm (tan, cream, brown, red brick), or mixed? A cool exterior points toward Charcoal, Pewter Gray or Slate. Warm points toward Barkwood, Shakewood or Weathered Wood. Mixed exteriors often land on Weathered Wood, which carries both gray and brown.
Step 2: decide on contrast
A roof darker than the walls looks grounded and traditional. A roof close to the wall color looks quieter and more modern. With UHDZ, the deeper shadow lines add texture even to a low-contrast choice.
Step 3: factor in Georgia conditions
- Heat: Charcoal runs hottest; Shakewood and Weathered Wood run cooler.
- Shade and algae: lighter colors show streaks first. UHDZ carries a 30-year algae warranty on StainGuard Plus PRO packages, which helps on wooded lots.
- HOA: confirm your color is on the approved list before ordering.
Step 4: test in real conditions
- Get full-size UHDZ shingles, not HDZ boards.
- View them outside at midday and late afternoon.
- Step back from the house, since colors read lighter at a distance.
- Look at a finished UHDZ roof if you can.
Step 5: match the details
Use the matching ridge cap, and plan drip edge and gutter colors at the same time so the edges look intentional. See the best shingle colors for Georgia heat and black streaks and algae on roofs.
