If you are an SRP customer in Tempe, a cool roof rebate can take up to $600 off a qualifying roof project. SRP’s cool roof rebate pays 30 cents per square foot of roof coverage on low-slope roofs that use qualifying cool roof products, up to $600, when installed by April 30, 2027, with the rebate submitted within six months of installation. Cool roofs reflect more sunlight and absorb less heat, which lowers roof temperatures and can reduce cooling loads during the Valley’s long summers.
After a summer with a 117-degree record day, many homeowners are looking hard at cooling costs. Here is how cool roof rebates work in Arizona, which roofs qualify, and whether a cool roof makes sense for your home.
What is a cool roof?
A cool roof uses materials that reflect a large share of sunlight and release absorbed heat efficiently. On low-slope roofs, this usually means a white or light-colored reflective coating over foam or membrane, or a reflective single-ply membrane. On steep-slope roofs, lighter-colored tile or specially rated shingles can improve reflectivity, although most rebate programs focus on low-slope roofs where the effect is largest.
In the Valley, flat and foam roofs are especially common on older homes, townhomes and commercial buildings, which makes cool roof coatings one of the most practical energy upgrades available.

Want to know if your flat or foam roof qualifies for a cool roof rebate?
How much can a cool roof actually save?
Savings depend on your roof area, insulation, ductwork location, how much of the home is under a flat roof and how you use your AC. Homes with a large flat or foam roof area over living space, and ducts in a hot attic or roof cavity, tend to see the most benefit. A cool roof also:
- Lowers roof surface temperatures, which slows heat aging of the roof itself.
- Can make upstairs or rooms under the flat roof more comfortable.
- Reduces thermal stress that causes cracking and blistering. Our guide to why foam roof coatings crack and blister explains that link.
We do not promise a specific bill reduction, because it varies so much by home. We can walk you through the factors on your roof so your expectations are realistic.
Is your roof a good candidate?
- Foam roofs due for a recoat are ideal. A reflective recoat restores UV protection and qualifies as a cool roof in many cases.
- Flat membrane or built-up roofs in good condition can often be coated with a reflective system. Our built-up roof maintenance guide covers when a coating makes sense.
- Roofs with ponding water need drainage fixed first. Coatings over ponding areas can fail early. See our article on ponding water on flat roofs.
- Steep-slope tile and shingle roofs gain less from rebates, but lighter colors and better attic ventilation still help.
How do you get a cool roof rebate?
- Confirm you are an SRP customer and review current rebate terms.
- Get a roof inspection to confirm the roof can take a coating or needs repairs first.
- Choose a qualifying cool roof product and schedule installation.
- Keep invoices, product data and photos.
- Submit the rebate within six months of installation.
Our foam roof repair and roof coating teams can help with product selection and paperwork.
Why does roof prep matter more than the coating?
A cool roof coating is only as good as the surface under it. Before any reflective system goes on, a proper job includes:
- Cleaning to remove dust, chalking and debris so the coating bonds. Valley roofs collect a lot of dust during haboob season.
- Repairs to blisters, cracks, soft spots, open seams and damaged flashing.
- Drainage fixes so water does not sit on the new coating.
- Correct thickness, applied in the conditions the manufacturer specifies. Thin coatings wear through fast under Arizona UV.
Skipping prep is the most common reason a new coating peels or wears out early, and a failed coating costs far more than any rebate is worth. When you compare quotes, ask each contractor how they prep the roof, what product they will use and at what thickness. Those answers tell you more than the price.
