FAQs
What is interlocking steel roofing and how is it different from conventional metal roofing panels?
Interlocking steel roofing uses panels that hook and lock into one another on all four sides, creating a continuous, watertight surface. Traditional exposed-fastener metal panels overlap and are secured with screws that penetrate the roof deck. The interlocking design hides the fasteners, eliminates potential leak points, provides superior wind uplift resistance, and gives the roof a cleaner appearance.
How does an interlocking steel roof perform in Tellico Plains’ weather?
Tellico Plains experiences high winds coming off the Cherohala Skyway, heavy rain, and occasional hail. The four-way locking system keeps panels firmly in place in winds of 120 mph or more, while the steel’s galvanized and baked-on paint finishes resist corrosion from humidity and acid rain. Most systems carry a Class 4 hail impact rating and a Class A fire rating, giving homeowners extra peace of mind in every season.
What profiles, colors, and finishes are available?
We offer standing-seam, shake, slate, and Mediterranean tile profiles, all manufactured from 26- or 24-gauge G-90 galvanized or Galvalume steel. Over 30 standard colors are available, including Energy Star-rated cool coatings that reflect solar heat. Custom color matching is also an option, and matte, high-gloss, and textured finishes can be selected to complement log cabins, craftsman homes, and mountain cottages common in the Tellico Plains area.
Will installation disrupt my daily routine and how long does it take?
A typical 2,000 sq ft home in Tellico Plains can be completed in 2–4 days, weather permitting. Because the new interlocking panels can often be installed over an existing shingle roof, tear-off noise and debris are reduced. Our crew protects landscaping, cleans the job site daily, and schedules final inspections around your availability, so you can remain at home with minimal interruption.
What maintenance does an interlocking steel roof require?
Maintenance is simple: rinse the roof once or twice a year with a garden hose to remove pollen and debris, keep gutters clear, and trim back overhanging branches. The concealed fastener system means there are no screws to back out or gaskets to replace. If a panel is ever damaged by falling limbs, it can be individually unlocked and replaced without disturbing the surrounding roof.
Is interlocking steel roofing energy-efficient and does it come with a warranty?
Yes. Cool-roof pigments reflect up to 70 % of solar heat, helping Tellico Plains homeowners cut summer attic temperatures by 30 °F and reduce cooling costs by 15–25 %. All panels meet or exceed ENERGY STAR® requirements and may qualify for federal tax credits. Each roof is backed by a transferable lifetime limited warranty covering manufacturer defects, 30–40 years of finish protection against fading or chalking, and a 120 mph wind warranty when installed by our certified team.
