Free sign-up with email or Google. You get 1 free render; free renders are watermarked.

These are the GAF Timberline HDZ shingle color names we found in GAF's own brochure, split into national and regional colors, with GAF's words for the ones it describes. Pick a direction, then try a light, medium or dark roof on a photo of your own house.

Roof shingle colors

Before and after examples

Example images are AI-generated: both the sample houses and their redesigns. Results change from render to render, so treat them as concepts, not exact product matches.

AI-drawn stand-in of a two-story white vinyl-sided colonial house with black shutters, a faded patchy brown shingle roof — Example 1 (prompt 1 below; the before is an AI-drawn stand-in house, not a real photo): the faded brown roof became a charcoal gray roof, mostly even, with a few faint light marks still near the ridge. The white siding, the black shutters, the chimneys, the portico and the lawn stayed. The charcoal is the model's guess at the words in the prompt; it is not GAF Charcoal. We ran it twice: the first run left the old streaks on the new roof, so we added "clean and even all over, with no stains, streaks, moss or old shingles left" to the prompt, and we show the second run.

The same house with a charcoal gray shingle roof; the white siding, the black shutters, the chimneys and the lawn kept — Example 1 (prompt 1 below; the before is an AI-drawn stand-in house, not a real photo): the faded brown roof became a charcoal gray roof, mostly even, with a few faint light marks still near the ridge. The white siding, the black shutters, the chimneys, the portico and the lawn stayed. The charcoal is the model's guess at the words in the prompt; it is not GAF Charcoal. We ran it twice: the first run left the old streaks on the new roof, so we added "clean and even all over, with no stains, streaks, moss or old shingles left" to the prompt, and we show the second run.

AI-drawn stand-in of a one-story light tan-sided ranch house with a faded gray shingle roof with dark streaks — Example 2 (prompt 2 below; the before is an AI-drawn stand-in house, not a real photo): the streaky gray roof became a slightly warmer gray-brown, but the change is small: the new roof is close to the old color, and a few dark streaks still show on the right side. The tan siding, the windows, the door and the lawn stayed. We used plain words, so this is not GAF Weathered Wood. We ran it twice: the first run left the old streaks on the new roof, so we added "clean and even all over, with no stains, streaks, moss or old shingles left" to the prompt, and we show the second run.

The same house with a slightly browner gray roof; the tan siding, the windows, the door and the lawn kept — Example 2 (prompt 2 below; the before is an AI-drawn stand-in house, not a real photo): the streaky gray roof became a slightly warmer gray-brown, but the change is small: the new roof is close to the old color, and a few dark streaks still show on the right side. The tan siding, the windows, the door and the lawn stayed. We used plain words, so this is not GAF Weathered Wood. We ran it twice: the first run left the old streaks on the new roof, so we added "clean and even all over, with no stains, streaks, moss or old shingles left" to the prompt, and we show the second run.

How to use this list

These are color names, not pictures of the product. The names below come from GAF's Timberline HDZ brochure (RESTZ145, 2024). Where GAF describes a color, we paraphrase its words. We show no product photos. GAF's brochure itself notes that colors on a screen or in print are not exact.

Our two example roofs are not GAF colors. They were made by an AI model from plain color words. They help you judge a light, medium or dark roof on a house, not a named shingle. We did not find sales data on which colors sell most, so this list is not a ranking.

Timberline HDZ national colors

GAF's brochure lists these nine as national colors: Weathered Wood, Charcoal, Pewter Gray, Barkwood, Shakewood, Hickory, Slate, Mission Brown and Hunter Green. The table gives GAF's own description for the five it describes in the copy we read.

Color name	What it looks like, per GAF
Charcoal	A deep gray-black that GAF calls the most neutral of its shades.
Pewter Gray	A mid gray that GAF says contrasts well with brick or stucco.
Slate	A cool gray with a green undertone.
Weathered Wood	A gray-brown that GAF calls a neutral that goes with many houses.
Shakewood	A warm blend of browns, tans and gold.

Harvest Blend and regional colors

Harvest Blend colors, which GAF says are not sold in every area: Nantucket Morning, Appalachian Sky, Golden Harvest and Cedar Falls.

Regional colors in the same brochure: Birchwood, Biscayne Blue, Copper Canyon, Driftwood, Fox Hollow Gray, Golden Amber, Oyster Gray, Patriot Red, Sunset Brick, White and Williamsburg Slate. Ask your roofer which of these are sold near you.

New colors for 2026

In January 2026, GAF announced a "Bold Definition" collection for Timberline HDZ with four new colors: Chestnut Valley, Cliffside, Midnight Mesa and Sierra Sand (reported by Roofers Coffee Shop). We did not find where they are sold, so ask a local supplier.

Names that cause mix-ups

Timberline HD is the older line that HDZ replaced, and Timberline UHDZ is a separate, thicker line, so a color list for one may not match the other. If a roofer quotes a GAF color, ask which line it is from.

Light, medium or dark roof?

The GAF descriptions above give a start: Charcoal as the most neutral choice, Pewter Gray against brick or stucco, Weathered Wood and Shakewood for warmer houses. Start with what you cannot change, the brick, the stone and the siding, then pick the roof. For more on this step, see roof and siding color combinations, exterior house colors with a black roof, with a gray roof and with a brown roof.

How to check a color before you order

Narrow it down online, then see the color for real. GAF's brochure notes that printed and on-screen colors are not exact, so ask your roofer for a real shingle sample.
Look at an installed roof in daylight. A blend of granules can read lighter, darker or warmer from the street than on a small sample.
Check availability. GAF marks some colors as regional or not sold in every area, so ask a local supplier before you fall for one.
Preview the depth on your house. Upload a photo in the tool at the top of this page, or use the roof visualizer, to compare a light, medium and dark roof before you pick a named color.

Two examples, and what the AI changed

The examples were run directly on an image model, not through the tool above, so your results will look different. The live tool may use a different model and settings from the ones we used (we used 4 processing steps). The roof colors are the model's reading of plain color words, not GAF colors.

Brown to charcoal. Example 1 replaces a faded brown roof on a white colonial and keeps the siding and shutters. The first run kept the old streaks; the second is cleaner.
Gray to gray-brown. Example 2 shows the model's limit: when the old and new colors are close, it changes very little. Ask for a clearly different color if you want to see a difference.

The exact prompts behind the examples

These are the edit prompts, word for word. Change the color words and the list of what stays to suit your house.

Prompt 1: charcoal gray-black shingles

Replace only the roof shingles with new architectural asphalt shingles in a deep neutral charcoal gray-black blend, clean and even all over, with no stains, streaks, moss or old shingles left. Keep the white siding, the black shutters, the trim, the windows, the front door, the gutters, the lawn, the sky and the camera angle exactly the same

Prompt 2: gray-brown weathered wood blend

Replace only the roof shingles with new architectural asphalt shingles in a gray-brown weathered wood blend, clean and even all over, with no stains, streaks, moss or old shingles left. Keep the tan siding, the trim, the windows, the front door, the gutters, the lawn, the sky and the camera angle exactly the same

Who this is for

Frequently asked questions

What are GAF's most common shingle colors?

GAF's Timberline HDZ brochure lists nine national colors: Weathered Wood, Charcoal, Pewter Gray, Barkwood, Shakewood, Hickory, Slate, Mission Brown and Hunter Green. The other colors are marked regional or Harvest Blend. GAF does not say which sell most, so this is not a ranking.

What does GAF Charcoal look like?

GAF describes Charcoal as a deep gray-black and calls it the most neutral of its shades. See a real sample in daylight before you choose.

What does GAF Weathered Wood look like?

GAF describes Weathered Wood as a gray-brown neutral. Because it mixes gray and brown, it can read warmer or cooler depending on the light and your siding.

Are all GAF colors sold everywhere?

No. GAF marks the Harvest Blend colors and a list of regional colors as not sold in every area. Ask a local roofer or supplier which colors they can get.

Is Timberline HDZ the same as Timberline HD?

No. Timberline HDZ replaced the older Timberline HD, and Timberline UHDZ is a separate line. Check which line a color list is for.

Are the roofs in the pictures real GAF colors?

No. The two examples were made by an AI model from plain color words. They are not GAF products and do not match any named color. Not affiliated with GAF. Colours are AI approximations; check real samples before you buy.

Can I see a new roof color on my own house?

Yes. Upload a photo of your house in the tool at the top of this page, describe the roof color in plain words and list what must stay the same. Use it to compare light, medium and dark roofs, then check real samples.

Is this tool free, and do I need an account?

Signing up is free and gives you 1 free render. Free renders carry an AiExterior watermark. You need to sign in with an email code or your Google account before a render starts. If you want more renders or clean images, paid plans are on the pricing page.
