Explore GAF Timberline HDZ colors, compare samples with your exterior and see a real Pewter Grey roof replacement in San Marcos.
A roof takes up a large part of your home’s exterior. Start your color decision with the materials that will stay: brick, stone, siding, trim and gutters. Then compare a short list of shingle samples outdoors before making the final selection.
Explore the GAF color selector
Use GAF’s interactive selector below to narrow your choices. Availability varies by location. Screen settings and lighting change how colors appear, so the tool is a starting point rather than a substitute for a physical sample.
Interactive resource supplied by GAF. Open the tool in a full window.
Look at your house as a whole
Warm brick and limestone, cool gray siding and painted trim can each change the way the same shingle looks. Compare samples beside those surfaces in daylight and from the street. Check both sunny and shaded areas. A small sample viewed indoors can give a different impression from a finished roof.
See Pewter Grey on a real Central Texas roof
Our San Marcos project documents the change from brown three-tab shingles to GAF Timberline HDZ architectural shingles in Pewter Grey. The before-and-after photographs let you compare the roof with the same house, landscaping and blue shutters.

Before you approve a color
Ask which colors are available for your exact product and delivery area.
Review a physical sample beside the house and keep the approved product and color in writing.
Check any applicable HOA requirements before ordering.
Confirm the ridge cap and other visible roof details in the proposal.
Build the selection into your estimate
Color is one decision in a complete replacement scope. Ask how the estimate treats decking, flashing, starter shingles and ventilation. We can discuss the appearance you want and the roof details your property needs.
