FAQs
How well does a metal roof stand up to the high winds and driving rain that come with Tennessee thunderstorms?
Properly installed 24- or 26-gauge steel panels are tested to ASTM E-1592 and can resist uplift pressures equal to 140–160 mph winds—well above the 115 mph design wind speed required by the Blount County building code. Because the panels interlock and are screwed to the deck or purlins, wind-driven rain cannot be blown beneath the seams the way it can with shingles. For Friendsville homes that see 50+ thunderstorm days a year, metal roofing gives one of the highest wind and water intrusion ratings available.
Is a metal roof more likely to be hit by lightning during a summer storm?
No. A metal roof does not attract lightning; the strike probability is determined by a structure’s height and location, not its roofing material. Should lightning hit, metal is actually safer than combustible materials because it is non-flammable and quickly disperses the electrical charge across the roof surface and down any grounded pathways. That means far less risk of fire compared with wood shakes or asphalt shingles.
Will my home be noisier under heavy rain or hail if I switch to metal?
Modern metal roofs installed over solid decking (OSB or plywood), synthetic underlayment, and existing attic insulation add only about 6–8 dB of sound—roughly the difference between a normal conversation and background music. If additional sound dampening is desired, we can add a high-density acoustic underlayment. Most homeowners are surprised at how little difference they notice once the roof is complete.
How does metal roofing handle hail compared to traditional shingles?
Steel and aluminum panels carry a UL 2218 Class 4 impact rating—the highest available. While very large hail can leave cosmetic dents, the panels will not crack, expose the deck, or lose water-shedding ability the way asphalt shingles do. After a severe hailstorm you can usually keep the same panels; if dents bother you, individual sections can be replaced without tearing off the whole roof.
What maintenance is required on a metal roof after the storm season?
Maintenance is minimal: (1) visually inspect panels, trim, and sealant once or twice a year; (2) check that exposed fasteners, if any, remain snug; (3) rinse off tree debris or pollen with a garden hose; (4) touch up any deep scratches to protect the paint finish. No granular loss, shingle curling, or frequent replacement is needed, and most manufacturers back the finish for 30–50 years.
Can a metal roof lower my homeowner’s insurance in Tennessee?
Many insurers operating in Tennessee—including State Farm, Farm Bureau, and Erie—offer 5 % to 35 % discounts on premiums for homes with UL 2218 Class 4 metal roofing because of its superior wind, hail, and fire resistance. Once your new roof is installed, we provide the documentation your carrier needs to apply the credit, which often offsets part of the upgrade cost.
