FAQs
How do Ten Mile’s relentless UV rays affect traditional roofing materials, and why is metal roofing a better choice?
In Ten Mile, roofs endure more than 2,500 hours of intense sunshine each year. On asphalt shingles and wood shakes, that ultraviolet radiation dries out the oils that keep them flexible, causing cracking, curling, and premature granule loss within 10–15 years. Metal roofing, by contrast, is made from steel or aluminum protected by baked-on fluoropolymer coatings that are engineered to deflect UV energy. The panels will not dry out, split, or become brittle, so they maintain their structural integrity and weather-tightness for 40–70 years—four to five times longer than most conventional roofs.
What special coatings or finishes do you apply to your metal panels to combat UV degradation?
Our standard system uses a Kynar 500®/Hylar 5000® polyvinylidene fluoride (PVDF) paint finish rated for "fade resistance level 5" (the highest in ASTM D2244 testing). This finish reflects up to 70 % of UV radiation and carries a 30-year non-prorated warranty against chalking and color fade. For extreme exposures, we also offer a two-coat ceramic-pigmented PVDF or a clear CERAM-A-STAR® 1050 topcoat, both of which add another layer of protection and enable a 40-year warranty. These coatings bond chemically to the galvanized or Galvalume® substrate, forming a barrier that blocks UV photons from ever reaching the metal underneath.
Will installing a reflective metal roof actually lower my cooling bills during Ten Mile’s hot summers?
Yes. "Cool-roof" rated metal panels feature infrared-reflective pigments that bounce both UV and IR wavelengths back into the atmosphere. Independent studies by Oak Ridge National Laboratory show that they keep attic temperatures 30–40 °F cooler than dark asphalt roofs. In a typical 2,000 sq ft home in Meigs County, that translates to 15–25 % lower summer air-conditioning costs, often saving $150–$300 per year. Those energy savings frequently offset the higher initial investment in less than a decade.
How long can I expect a UV-resistant metal roof to last in Ten Mile, and what warranty do you provide?
A properly installed, fully coated steel or aluminum roof should last 50 years or more in our climate. The substrate itself carries a 40- or 50-year manufacturer’s corrosion warranty, while our PVDF color finish is warranted for 30–40 years against fade, chalk, and film integrity loss. We also provide a 10-year workmanship warranty that covers any installation-related leaks or fastener issues. Many of the original metal roofs we installed in the early 1990s are still performing like new today.
Will the color of my metal roof fade or chalk under constant sun exposure?
All painted surfaces will experience some gradual change, but high-grade PVDF finishes slow that process dramatically. The color-stable ceramic pigments resist breakdown, limiting fade to Delta-E 5 or less over 30 years—an amount most homeowners can’t detect with the naked eye. To further minimize chalk (the white residue that sometimes forms on painted metals), we use low-porosity resin systems and recommend periodic rinsing with a garden hose to remove pollen and dirt. If excessive fading or chalking occurs within the warranty period, the manufacturer will pay to refinish or replace the affected panels.
What maintenance is required to keep a metal roof performing against UV damage?
Metal roofs are largely maintenance-free. Unlike shingles, they never need sealing or re-coating to stay UV-resistant. We advise homeowners to (1) inspect and clear debris from valleys and gutters twice each year, (2) wash the panels with mild soap and water if pollen, salt, or bird droppings accumulate, and (3) check the neoprene washers on exposed-fastener systems after 15 years, replacing any that harden. Following these steps, your roof will continue to reflect UV rays effectively and remain watertight for decades.
