FAQs
How does East Tennessee’s climate affect metal roofing performance in Petros?
Petros sits in a region that sees strong summer storms, high humidity, occasional hail, and the freeze-thaw cycles of the Cumberland Plateau. Quality metal roofing is engineered to meet 120-mph+ wind ratings, shed heavy rain quickly, and resist damage from hail up to 2". Its interlocking panels and concealed fasteners keep out driven rain and melting snow, while factory-applied Kynar 500® finishes protect against the accelerated UV fade common in our high-sun, high-humidity climate.
What types of metal roofing are best suited for homes in Petros?
For most residences we recommend 26- or 24-gauge Galvalume steel standing-seam panels with a baked-on Kynar® finish. Standing-seam roofs have raised ribs that hide fasteners and allow the metal to expand and contract without loosening screws. If you prefer a more traditional look, stamped metal shingles or stone-coated steel panels also perform well in East Tennessee weather while mimicking shake, slate, or tile.
How long will a metal roof last in Petros compared to asphalt shingles?
A properly installed metal roof in our climate will last 40–70 years, even longer with periodic wash-downs and fastener checks. Standard architectural asphalt shingles typically need replacement every 15–25 years in East Tennessee due to UV degradation, algae growth, and wind uplift. Over two to three roof cycles, metal typically costs less overall despite the higher upfront investment.
Will a metal roof make my home hotter during Petros’s summer heat?
No. Modern metal roofing panels are "cool-roof" rated. They reflect 25–65 % of solar radiation and re-emit much of the heat they do absorb. When combined with proper attic ventilation, a metal roof can lower attic temperatures 10–15 °F compared to dark asphalt shingles, which helps reduce air-conditioning costs and extends the life of your HVAC system.
How much maintenance does a metal roof require in East Tennessee?
Maintenance is minimal. Once a year—or after a major wind event—inspect for branches, clean out valleys and gutters, and rinse pollen or leaf stains with a garden hose. Every 10–15 years, have a professional check sealant at penetrations and verify that above-sheathing ventilation is clear. You’ll avoid the granule loss, curling, and algae staining that plague asphalt roofs in our humid environment.
Can a metal roof be installed over my existing shingles in Petros?
Often yes. Local building codes allow one existing layer of shingles to remain as long as the decking is sound and the added load is within structural limits. Installing over shingles saves tear-off costs and provides an extra insulation layer. We fasten 1"x3" purlins over the shingles to create an even deck and ventilation gap before attaching the standing-seam panels. A site inspection will confirm whether your roof qualifies.
