FAQs
Why is metal roofing a smart choice for homes in Maryville that face frequent summer storms?
Maryville’s summer weather often brings high winds, driving rain, and occasional hail. Metal roofing is specifically engineered to withstand these extremes. Panels are interlocked and fastened with concealed screws, creating a continuous, water-tight surface that resists wind uplift far better than traditional shingles. Many metal systems carry wind ratings of 140 mph or higher—well above the gusts typically recorded in Blount County. In addition, metal’s hard, impact-resistant surface disperses hail strikes, minimizing dents and virtually eliminating the risk of punctures or leaks. Homeowners gain superior protection, fewer storm-related repairs, and longer roof life.
How does metal roofing perform against hail and high winds common to East Tennessee summers?
Most premium metal roofing panels used in Maryville are UL 2218 Class 4 impact-rated, the highest rating available for hail resistance. This means they are tested to withstand 2-inch steel balls dropped from 20 feet with no surface rupture. In practical terms, that translates to surviving severe hailstorms with little or no damage. For wind, metal roofs achieve ASTM E1592 and UL 580 ratings verifying uplift resistance at or above 140 mph. Properly installed by a certified contractor, the continuous panels and secure clip-fastening system prevent wind-driven rain from working under the roof, stopping the blow-offs and water intrusion that shingles often suffer.
Will a metal roof make my house noisier during rain or thunderstorms?
Not when installed correctly. Today’s residential metal roofs are mounted over solid decking (usually 7⁄16-inch OSB or plywood) with an underlayment and sometimes an attic insulation layer. These components absorb much of the sound energy from rain or hail. Independent studies show the interior noise level under a metal roof is comparable to—or even quieter than—a typical asphalt shingle roof. If you have vaulted ceilings or minimal attic insulation, additional sound-dampening options such as high-density foam backers can be added during installation.
What is the expected lifespan and maintenance schedule for a metal roof in Maryville’s climate?
A quality steel or aluminum roof can last 40–70 years, more than double the service life of asphalt shingles. The baked-on PVDF (Kynar 500®) finish resists the intense UV exposure of East Tennessee summers, so fading, chalking, and peeling are minimal. Routine maintenance is simple: keep gutters clear, remove branches or debris after storms, and schedule a professional inspection every 3–5 years to verify fasteners and sealant points are intact. Because metal does not absorb water, there is no risk of mold growth or shingle granule loss, which drastically lowers ongoing upkeep costs.
Can metal roofing be installed over my existing shingles, and is that advisable in Blount County?
In many cases, yes. Local building codes allow a metal roof to be installed over a single layer of asphalt shingles provided the decking is structurally sound. Applying a synthetic underlayment or spacer system between the shingles and metal panels helps with ventilation and minimizes any telegraphing of shingle seams. Going ‘over-roof’ saves tear-off labor and landfill fees, reduces installation time, and provides an extra barrier against heat and noise. However, if there are existing leaks, wood rot, or more than one shingle layer, a full tear-off is recommended so the substrate can be repaired before the new metal system is attached.
How do cost and energy efficiency compare to other roofing options for Maryville homeowners concerned about hot summers?
Upfront, a standing-seam metal roof typically costs 2–3 times more than basic architectural shingles. However, its longevity (40–70 years) means most homeowners will never need another replacement, making the lifetime cost competitive or even lower. Metal’s high solar reflectance and emissivity can reduce cooling loads by 10–25 percent, according to Oak Ridge National Laboratory studies. Many coatings are ENERGY STAR® compliant, reflecting more infrared heat away from your attic. In Tennessee, this translates to cooler interior temperatures, lower air-conditioning bills, and potentially higher resale value due to the roof’s durability and energy-saving reputation.
