FAQs
What does “factory-certified installation” mean for metal roofing?
A factory-certified installation is performed by a contractor who has been trained, tested, and approved by the metal-roof manufacturer. The crew follows the exact fastening patterns, underlayment specs, trim details, and sealant procedures the factory engineers designed, and their work is periodically audited. For you, this means the roof is installed to the same standard the panels were fabricated for, your full material warranty remains valid, and you gain an extra layer of workmanship coverage that non-certified contractors cannot provide.
Why is metal roofing a smart choice for homes and businesses in Chattanooga?
Chattanooga’s humid summers, occasional ice storms, and frequent high-wind events demand a roof that can handle a wide range of stresses. Factory-finished steel or aluminum panels shed rain quickly, resist moss and mildew growth, and carry wind-uplift ratings of 120–140 mph—well above local code. Metal also reflects much of the sun’s radiant heat, which can drop attic temperatures by up to 20 °F and trim cooling costs. In winter, its smooth surface lets snow and ice slide off, reducing structural load and leak risk. Finally, a Class A fire rating and top-tier hail resistance help lower insurance premiums in many Hamilton County policies.
How long will a factory-certified metal roof last, and what warranty is included?
Properly installed metal roofs in Chattanooga routinely last 40–70 years. Our manufacturers back the panel coating against fading or chalking for up to 40 years and guarantee the base metal against perforation from rust for 30–50 years. Because we are factory-certified, you also receive a 5- to 10-year workmanship warranty that the factory itself underwrites. That means if a leak develops due to installation error, both the contractor and the manufacturer are responsible for repairs—double protection you won’t get with uncertified installations.
Will a metal roof make my home hotter or noisier during summer storms?
No. Modern metal roofing systems are installed over a solid deck, high-performance underlayment, and optional vented battens or foam insulation. That assembly blocks most sound—independent tests show indoor rain noise is comparable to asphalt shingles. Heat gain isn’t a problem either: factory-applied “cool roof” coatings reflect 25–70 % of solar energy, and the air space beneath the panels promotes convective cooling. Many Chattanooga homeowners report interior temperatures 5–15 °F cooler after switching from dark shingles to a reflective metal finish.
Can a factory-certified metal roof be installed over existing shingles?
Often, yes. Chattanooga building codes allow a new metal roof to be installed over one layer of asphalt shingles if the deck is sound and local load limits are met. Our factory guidelines specify using vented spacer purlins or synthetic underlayment to separate the metals from the old shingles, preventing abrasion and moisture trapping. By skipping tear-off you save on disposal fees and keep tons of waste out of landfills. However, if there are soft spots, excessive layers, or ventilation issues, we’ll recommend a full tear-off before installation to protect your warranty.
How much does a factory-certified metal roof cost in Chattanooga, and what affects the price?
Installed prices typically range from $9 to $14 per square foot for standing-seam steel and $11 to $18 for premium aluminum or copper profiles. Key cost factors include: • Roof size and pitch – Steep or complex roofs take more labor. • Panel type – Snap-lock panels cost less than mechanically seamed or stamped shake-look panels. • Underlayment and insulation upgrades – High-temp ice-and-water shield or vented battens add durability and energy savings. • Tear-off requirements – Removing old roofing adds $1–$2 per square foot. • Flashing and trim details – Custom chimney, valley, or skylight flashings increase material time.
