FAQs
What exactly is an interlocking steel roof and how does it differ from traditional metal panels?
Interlocking steel roofing is made of engineered panels that snap or lock together on all four sides, forming a continuous, watertight surface. Unlike exposed-fastener metal panels, the fasteners on an interlocking system are hidden beneath the overlap, so they are protected from weather and UV exposure. This design increases wind uplift resistance, prevents leaks at screw holes, and creates a cleaner appearance that resembles architectural shingles, slate, or shake.
Why is an interlocking steel roof a good choice for homes in Estill Springs, TN?
Estill Springs experiences hot, humid summers, occasional hail, and strong storm fronts that can bring 100+ mph wind gusts. Interlocking steel panels are rated for winds up to 140 mph, are Class 4 impact-resistant against hail, and have high-reflectivity coatings that deflect solar heat, lowering attic temperatures by 10-15 °F. The steel’s baked-on finish also resists mildew and algae—common issues in our Tennessee climate—so your roof keeps its color longer than asphalt shingles.
How long will an interlocking steel roof last and what maintenance is required?
A properly installed interlocking steel roof carries a 50-year or lifetime manufacturer’s warranty and can realistically last 60 years or more. Maintenance is minimal: rinse off pollen or debris with a garden hose once or twice a year, keep gutters clear, and inspect flashings after severe storms. Because the fasteners are concealed, there are no exposed screws to back out or replace over time, unlike typical ribbed metal panels.
Is a steel roof noisy during rain or hail?
When installed over solid sheathing and underlayment—as current building codes and our crews require—an interlocking steel roof is no louder than an asphalt shingle roof. The decking, synthetic underlayment, attic insulation, and the air gap created by the panel profile all act as sound dampeners. Most homeowners in Estill Springs tell us the new roof is actually quieter than their previous shingle roof because the tight locks prevent fluttering in high winds.
Can an interlocking steel roof be installed over my existing shingles, and will it add too much weight?
In many cases, yes. Interlocking steel panels weigh only 0.9–1.3 lb per square foot—about one-third the weight of asphalt shingles and one-tenth that of tile. If your current deck is in good condition and local codes allow, we can install a vented underlayment and attach the new steel panels directly over the old roof, saving tear-off labor and landfill fees. Our estimator will inspect your decking to confirm it meets structural and ventilation requirements.
What is the cost of an interlocking steel roof compared to high-quality asphalt shingles, and what financing options are available?
In Estill Springs, an interlocking steel roof averages $9–$13 per square foot installed, while a premium architectural shingle roof runs $5–$7 per square foot. Although the upfront cost is higher, the steel roof usually pays for itself in energy savings, insurance discounts of up to 30%, and by eliminating at least one full shingle replacement cycle. We offer 0% same-as-cash plans for 12 months and low-interest financing up to 120 months to make the investment budget-friendly.
