FAQs
What is a fade-resistant Kynar coating and how is it different from ordinary metal-roof paint?
Kynar® 500 (also called PVDF) is a premium resin that is mixed with high-performance pigments and then baked onto the steel or aluminum panel at the mill. Unlike standard SMP or polyester paints that sit on the surface, the PVDF molecules chemically bond to the metal, creating an ultra-dense shield that resists UV degradation, chalking and chemical attack. The result is a roof that keeps its original color 2–4 × longer than conventional painted metal and carries much longer fade and chalk warranties.
How long will a Kynar-coated metal roof keep its color in Sale Creek’s climate?
Because the PVDF resin blocks >70 % of UV radiation and seals out moisture, most manufacturers back their Kynar finishes with a 30- to 40-year fade warranty (typically ΔE ≤ 5) and a 30-year chalk warranty (usually chalk rating 8 or better). In the humid, high-sun East Tennessee climate that surrounds Sale Creek, real-world testing shows color retention well past 30 years with only minimal fading that is usually invisible from ground level.
Does a Kynar 500 roof improve energy efficiency for homes and businesses in Sale Creek?
Yes. Many Kynar colors are "cool roof" formulations that include infrared-reflective pigments. They bounce back 25–70 % of the sun’s heat, keeping the metal panel cooler and lowering attic temperatures by up to 20 °F. Homeowners commonly see 10–25 % reductions in summer A/C costs, and several colors meet ENERGY STAR® and TVA incentives for reflective roofing.
What kind of maintenance does a Kynar-coated metal roof require?
Maintenance is simple: (1) once or twice a year rinse the panels and gutters with a garden hose to remove dust and pollen; (2) if tree sap or soot builds up, wash with a soft brush, mild dish soap and water—avoid abrasive pads, power-washing at close range, or chlorine bleach; (3) inspect fasteners, sealants and trims and clear any debris from valleys after storms; (4) if you need to walk on the roof, use soft-soled shoes and follow the panel manufacturer’s foot-traffic guidelines. No repainting is expected for decades.
Is Kynar-coated metal roofing durable enough for the storms, humidity and occasional hail we get in Sale Creek?
Absolutely. The underlying 24- or 26-gauge steel (or .032 aluminum) panels are impact-rated (Class 4) for hail and carry wind-uplift approvals up to 140 mph when properly fastened. The PVDF finish resists corrosion even in high-humidity or light industrial environments, so rust and mildew are rarely an issue. Panels also achieve a Class A fire rating, giving you top-tier protection against lightning or ember exposure.
What warranties are offered with Kynar-coated metal roofing and what do they cover?
Most reputable mills provide a combo warranty package: 40- to 45-year film integrity (no flaking, peeling or cracking), 30-year fade/chalk coverage, and a 20- to 25-year substrate warranty against perforation due to rust (for Galvalume® steel) or corrosion (for aluminum). When the roof is installed by a certified contractor, you can also add a separate 5- to 10-year workmanship warranty that covers leaks related to labor or flashing errors. These warranties are generally non-prorated and transferable to the next homeowner.
