Cool roofs are designed to reflect more sunlight and absorb less heat than standard roofing materials, keeping your home cooler and potentially saving on energy costs. Asphalt shingles can qualify as cool roofs if they meet specific criteria set by programs like ENERGY STAR or the Cool Roof Rating Council (CRRC). These shingles have special reflective granules that bounce back sunlight, reducing heat buildup. Eligibility for cool roofing often depends on the shingles’ solar reflectance index (SRI), which measures how well the material reflects solar energy. Darker traditional asphalt shingles usually don’t qualify because they absorb more heat. However, some light-colored or specially coated asphalt shingles can meet the cool roof standards, making them a good fit for homeowners looking to improve energy efficiency without sacrificing the familiar look of asphalt roofing.
To check if your asphalt shingles might be eligible, start by identifying the shingle brand and model; this information is often on product packaging or can be found through your roofing warranty documents. You can also look up your shingles on the ENERGY STAR or Cool Roof Rating Council websites to see if they meet cool roof requirements. If you’re considering a new roof or replacement, ask your contractor, “Do these specific asphalt shingles meet ENERGY STAR or CRRC cool roof standards?” and “How will their cool roof properties impact my home’s energy usage in our local climate?” If you suspect your roof is aging or overheating, it’s wise to call a professional to inspect for issues like damaged granules or sealant failure, which can reduce reflectivity. Avoid trying to coat or alter shingles yourself without guidance, as improper DIY fixes can void warranties and cause further damage.
