Light colored shingles reflect more sunlight than dark ones, so the roof and attic stay a little cooler in hot weather. They also show dirt and streaks more, and they change the look of a house more than people expect. Below are the honest pros and cons, what cool-roof ratings mean, and the light colors the big brands sell. Then try a light roof and a dark roof on a photo of your own house.
They help in hot, sunny climates. A lighter roof absorbs less sun, so less heat reaches the attic. How much that lowers a cooling bill depends on your climate, attic insulation and ventilation, so treat any savings figure with care.
In cold climates a dark roof gains a little more winter heat, and a light roof gives up that gain. Insulation and ventilation matter more than roof color in most houses.
Weigh them for your climate and street.
Less heat in hot climates. A fresh, airy look on coastal, Mediterranean and modern houses. Some cool-roof shingles meet local energy codes.
Show dirt, moss and algae streaks more. Can look glaring or washed out on light siding. Less winter heat gain. Fewer color choices.
Some HOAs limit roof colors; check first. Neutral light grays and tans are safer for resale than white.
Solar Reflectance Index (SRI) combines how much sunlight a roof reflects and how well it sheds heat. Higher means cooler. Most standard asphalt shingles score low; cool-roof shingles use reflective granules to score higher.
Ratings come from the Cool Roof Rating Council (CRRC). California's Title 24 energy code and some cities set minimum ratings for some re-roofs. Ask your roofer what your local code requires.
Cool Barkwood, Cool Weathered Wood and Cool Antique Slate. GAF lists SRI of about 27 to 30.
Shasta White (Supreme) is its lightest color; older COOL brochures list it at SRI 29. Sierra Gray and Sand Castle are light Duration colors.
Solaris cool-roof granules, with SRI above 20 per its brochure.
White: Owens Corning Shasta White. Light gray: Owens Corning Sierra Gray, GAF Oyster Gray, CertainTeed Silver Birch. Gray-beige: GAF Birchwood. Light tan: Owens Corning Sand Castle, GAF Driftwood. Ratings vary by product; check the current data sheet.
A picture helps you choose a direction. These checks help you choose the actual shingle.
A roof looks lighter in full sun and darker in shade, and a small swatch looks different from a whole roof. Ask your roofer or supplier for a sample board and hold it next to your siding or brick outside.
Manufacturers sell some colors only in some regions, and the list can change. Ask a local supplier which colors they stock before you fall for one.
A Driftwood or a Pewter from one brand is not the same color as one with the same name from another brand. Always say the brand, the product line and the color name together.
Many homeowner associations approve roof colors. Ask before you order, and bring the picture with you.
Dark roofs absorb more heat, light roofs reflect more. In hot areas ask about "cool" or reflective shingles.
Save your before and after picture and take it to two or three local roofers when you ask for quotes. Tell each one the brand, the product line and the color name you want, for example "Owens Corning Duration, Driftwood" or "GAF Timberline HDZ, Charcoal".
Ask each roofer to bring a sample of a light color and its cool-roof rating and to confirm it is stocked in your area. A picture of your own house makes it easy for them to see what you mean.
The tool draws an approximation of each color from a description of its tone. It is not the manufacturer's swatch, and the shingle pattern is a general architectural or 3-tab look, not a specific product.
It is a preview, not a quote, a survey, or a check of what your roof can carry. It does not measure the roof or give prices.
Roof-like cladding on walls, such as hung tiles on a gable, can change along with the roof. Compare the result with your photo.

They reflect more sunlight, which helps in hot, sunny climates. How much depends on your climate, insulation and ventilation.
Usually less so. A dark roof gains a little winter heat. Ask a local roofer about your climate.
Solar Reflectance Index: how well a roof reflects sun and sheds heat. Higher is cooler. Cool-roof shingles score higher than standard ones.
Yes, more than dark ones. Algae streaks and moss are more visible on light roofs.
White (Owens Corning Shasta White), light grays (Sierra Gray, GAF Oyster Gray), gray-beige (GAF Birchwood) and light tans (Sand Castle, GAF Driftwood), plus cool-roof versions of some colors.
No. It shows the look only. Ask for the product's CRRC rating to compare heat.
The picture is an approximation. Real colors depend on the light and the batch, so look at a physical sample in daylight before you order.
