FAQs

What advantages does a metal roof offer for homes in Johnson City's climate?

Johnson City experiences hot, humid summers, heavy rain, occasional hail, and winter freeze–thaw cycles. Metal roofing stands up to all of these conditions. Panels are interlocking and shed rain quickly, reducing the risk of leaks and moisture-related mold. The factory-applied coatings reflect a large portion of solar heat, helping lower attic temperatures and air-conditioning costs during our warm months. Metal is also extremely impact-resistant, so hail or falling limbs are far less likely to penetrate the roof. Finally, the material’s minimal water absorption prevents cracking and splitting during winter freezes, giving homeowners a durable, low-maintenance solution year-round.

How long will a metal roof last compared with a traditional asphalt shingle roof?

An asphalt shingle roof in eastern Tennessee typically lasts 15–20 years before granule loss, curling, and wind damage force replacement. A properly installed, quality metal roof can last 40–70 years—two to three times longer. The panels are made of galvanized or Galvalume steel, aluminum, or standing-seam copper, all of which resist corrosion, UV breakdown, and wind uplift. Most manufacturers back their products with 30–50-year warranties, so you can expect decades of service with little more than routine inspection and an occasional cleaning.

Will a metal roof make my home hotter or cooler?

Contrary to popular belief, metal roofs typically make homes cooler. Painted or granular-coated panels are "cool-roof" rated, reflecting 30–60 % of the solar energy that asphalt shingles absorb. This reduced heat gain can lower peak attic temperatures by up to 20 °F, easing the load on your HVAC system and cutting summer energy bills by 10–25 %. For even greater efficiency, we install a vented ridge cap and, if needed, an additional radiant barrier beneath the decking to create a continuous airflow path that carries hot air out of the attic.

Can a metal roof be installed over my existing shingle roof?

In many cases, yes. Johnson City building codes allow a metal roof to be installed over a single layer of asphalt shingles, provided the existing deck is sound and local weight-load requirements are met. Installing over shingles saves tear-off disposal costs and keeps old materials out of landfills. We fasten either a 1×4 or 2×2 wood batten grid or a synthetic underlayment directly on top of the shingles, then attach the metal panels. However, if the shingles are severely curled, the decking is rotted, or the roof already has two layers, a full tear-off is recommended for best results.

How much does a metal roof cost in Johnson City, and what factors affect pricing?

On average, metal roofing in the Tri-Cities area runs $8–$14 per square foot installed, versus $4–$6 for architectural asphalt shingles. The final price depends on several factors: • Panel style: exposed-fastener panels are the most economical; standing-seam and specialty metals cost more. • Metal type and gauge: steel (26–29 gauge) is standard, but thicker 24-gauge steel, aluminum, or copper raise material costs. • Roof complexity: multiple valleys, dormers, skylights, or steep pitches require more labor and custom flashing. • Tear-off requirements: removing old shingles adds approximately $1–$2 per square foot. • Insulation or ventilation upgrades: adding radiant barriers or insulation boards increases upfront cost but improves long-term energy savings. While the investment is higher than asphalt, the longer lifespan, lower maintenance, and energy savings often make the lifetime cost of metal roofing lower.

Are metal roofs noisy during rain or hail storms?

A properly installed residential metal roof is no louder than an asphalt shingle roof. The key is the solid roof deck: metal panels are fastened to plywood or OSB sheathing with an underlayment in between, which dampens sound. When attic insulation and drywall ceilings are factored in, interior noise levels are typically the same or even lower than with shingles. For homeowners who desire extra sound absorption, we can add a high-density acoustic underlayment or a layer of rigid foam insulation beneath the panels.
