FAQs
What are exposed-fastener metal roofing panels, and how do they differ from standing-seam systems?
Exposed-fastener panels are steel or aluminum sheets formed with ribs and flat sections that are fastened directly to the roof deck with color-matched screws and washers driven through the top of the panel. Because the screws remain visible (exposed), the system installs faster and costs less than standing-seam roofs, whose concealed clips and interlocking seams hide every fastener. Both systems offer the same base metal, paint finishes and weather resistance, but exposed-fastener roofs have a slightly lower wind uplift rating and require periodic screw replacement, whereas standing-seam roofs do not.
Are exposed-fastener panels a good choice for homes and businesses in Corryton’s climate?
Yes. Corryton experiences hot, humid summers, cold snaps in winter and the occasional severe thunderstorm. 26- or 29-gauge galvanized steel panels with Kynar 500® paint provide excellent corrosion resistance against humidity and acid rain, reflect solar heat to reduce cooling bills and easily shed snow and ice. Panels are tested to withstand winds well above the regional design speed, making them a durable option for both residential and light-commercial roofs in Knox County.
How long will an exposed-fastener metal roof last, and what maintenance does it need?
With proper installation and upkeep, an exposed-fastener roof in Corryton can last 40–50 years. The painted finish is warrantied for up to 40 years against chalk and fade, and the galvanized substrate carries a 25-year corrosion warranty. Maintenance is simple: keep gutters clear, remove debris from valleys, wash the roof annually with mild detergent, and have a professional inspect fasteners every 8–10 years. Screws may need to be tightened or replaced as the neoprene washers age, a service we provide at minimal cost.
Will the exposed fasteners eventually leak?
When installed correctly with high-quality long-life screws and EPDM washers, the fasteners create a watertight seal. Over decades, thermal movement can loosen some screws or compress the washer, allowing drips. That is why we specify Lifetime G-90 or G-100 screws with oversized washers and include one complimentary fastener inspection at year 5. If future tightening or replacement is needed, it is a quick, inexpensive process that restores full water-tightness. Most homeowners never experience a leak provided routine inspections are performed.
How does the cost of an exposed-fastener metal roof compare to asphalt shingles in Corryton?
On average, an exposed-fastener metal roof runs $4.50–$7.00 per square foot installed, depending on panel gauge, color and roof complexity. A premium architectural asphalt shingle typically costs $4.00–$6.00 per square foot locally. While the upfront price is similar, the metal roof lasts more than twice as long, reduces energy bills by 10–20 %, and may qualify for insurance discounts, making its lifetime cost significantly lower than shingles.
Can you install exposed-fastener panels over my existing shingles, and how long will the job take?
In many cases, yes. Local building codes allow a metal-over-shingle installation if the existing roof deck is sound and there is only one layer of shingles. We attach 1×4 purlins through the shingles into the rafters to create a flat surface and ventilation gap before securing the panels. This saves tear-off costs and reduces landfill waste. A typical 2,500-sq-ft Corryton home can be completed in 2–3 days; larger or complex roofs may take up to a week. Every project begins with a free on-site inspection so we can give you an accurate timeline.
