FAQs
Why is UV exposure a significant concern for roofs in Calhoun?
Calhoun experiences a humid subtropical climate with long, sunny summers. The high number of clear days and elevated UV index accelerate the breakdown of roofing materials, causing fading, brittleness, and loss of waterproofing. Addressing UV exposure through proper material selection and protective coatings extends a roof’s lifespan in our region.
What roofing materials offer the best UV resistance for Calhoun homes and businesses?
Metal roofs with reflective coatings, high-quality architectural asphalt shingles infused with ceramic granules, and single-ply membranes like PVC or TPO that contain UV inhibitors perform exceptionally well. These materials reflect or dissipate sunlight, preventing premature aging and reducing heat gain inside the building.
How often should a UV-exposed roof be inspected in Calhoun?
Because of the intense sun and occasional severe storms, we recommend semi-annual inspections—once in spring and once in fall. Regular checks allow us to spot UV-induced granule loss, membrane cracks, or coating deterioration before they lead to leaks or structural damage.
Can a UV-protective roof coating be applied to an existing roof?
Yes. Elastomeric and silicone roof coatings can be applied to many existing substrates, including metal, modified bitumen, and some aged single-ply systems. They create a seamless, reflective barrier that blocks UV rays, lowers roof temperature, and can add 10–15 years to the roof’s service life at a fraction of replacement cost.
How does UV exposure affect energy bills in Calhoun?
Roofs that absorb excessive UV radiation heat up your attic and living spaces, forcing air-conditioning systems to work harder. Cool roof technologies—such as light-colored membranes or reflective coatings—can reduce roof surface temperatures by up to 50°F, cutting summer cooling costs by 10–30 % in Calhoun’s climate.
What warranty options are available for UV-protective roofing installations?
Manufacturers typically offer 20- to 50-year material warranties on UV-resistant shingles, metal panels, and single-ply membranes when installed by certified contractors. We also provide workmanship warranties ranging from 5 to 15 years. Some coating systems include renewable warranties, meaning we can re-coat at the end of the term and extend coverage without full replacement.
