FAQs
How does a metal roof protect my Kingsport home from driving rain compared to asphalt shingles?
High-quality steel or aluminum panels are interlocked and fastened with concealed screws or clips, creating a continuous watertight surface. Rainwater sheds quickly because the panels have a smooth finish and a minimum 3:12 roof pitch. By contrast, asphalt shingles rely on overlapping layers that can lift or curl in strong winds, allowing wind-driven water to back up underneath. A properly installed metal roof is also rated to withstand wind speeds of 120–140 mph, which is well above the typical thunderstorm gusts we see in Kingsport, so you get superior protection against both wind and water infiltration.
Will a metal roof be noisy during heavy rainstorms?
Not if it is installed correctly. Modern metal roofing systems include an underlayment—usually a synthetic moisture barrier or high-temperature ice-and-water shield—plus the existing roof decking. These layers absorb much of the impact sound. Inside the attic, insulation further dampens noise. Studies show interior sound levels on a metal roof are within 5–6 dB of an asphalt roof, which the human ear barely notices. If you still want extra quiet, we can add a thin foam backer or use clip-mounted standing-seam panels that allow a small air gap, both of which reduce resonance.
What gauge of metal roofing is best for the high winds and driving rain we experience in Northeast Tennessee?
For residential applications in Kingsport, we recommend 24-gauge standing-seam steel or 0.032-inch aluminum panels. Both meet UL 580 Class 90 uplift standards and carry Miami-Dade or ASTM E1592 approvals for wind resistance. Thinner 26-gauge panels are acceptable on low-budget projects but may dent more easily in hail and can flex in strong gusts. If you live on a ridge or in an open field where wind exposure is extreme, 22-gauge steel with a 180-degree double-lock seam provides maximum strength and weathertightness.
How long will a metal roof last in Kingsport’s climate, and what maintenance does it need?
Properly installed painted steel or aluminum metal roofing lasts 40–70 years—about two to three times longer than asphalt shingles. The kynar or hylar paint finish resists fading, chalking, and corrosion even with our humid summers. Routine maintenance involves clearing tree debris from valleys and gutters twice a year, inspecting fasteners and sealant at penetrations every 5–10 years, and washing pollen or mildew off the surface with a garden hose as needed. Most manufacturers back the paint for 30-40 years and offer a separate 25- to 50-year warranty against rust or perforation.
Is metal roofing more expensive than shingles, and what long-term savings can I expect?
Up-front, a standing-seam metal roof in Kingsport typically costs 2–2.5 times more than a mid-grade architectural shingle roof. However, because metal lasts two to three roof cycles, you avoid future tear-offs and disposal fees. Energy savings are another benefit: metal’s reflective finishes can reduce summer cooling bills by 10–25 %, and proper attic ventilation can add winter savings too. Insurance carriers often grant policy discounts of 5–15 % for metal because it is fire- and hail-resistant. When you factor in longevity, energy efficiency, and lower insurance premiums, a metal roof frequently delivers the lowest lifetime cost of any roofing material.
Can you install a metal roof over my existing shingles, and how long will the project take?
Yes, in many cases we can install directly over one layer of asphalt shingles using a vented metal-to-deck underlayment or a wood purlin system. Local codes in Kingsport allow one recover layer provided the deck is sound, the existing shingles are flat, and there is no trapped moisture. An overlay saves time and disposal fees, and it adds an extra sound-deadening layer. A typical 2,500 sq ft home takes 3–5 working days from material delivery to final inspection, depending on roof complexity and weather. If tear-off is required, add one to two extra days.
