FAQs
What are screw-down panel metal roofs and how do they differ from standing-seam systems?
A screw-down panel roof (also called an exposed-fastener roof) uses large metal panels that are secured directly to the decking or purlins with corrosion-resistant screws and neoprene washers. The heads of the screws remain visible on the finished roof surface. By contrast, a standing-seam roof hides the fasteners beneath interlocking seams. Because a screw-down system has fewer parts and simpler profiles, material and labor costs are typically 20-40 % lower than standing seam. The trade-off is that the exposed fasteners have to be monitored and occasionally tightened or replaced over the life of the roof.
Is a screw-down metal roof a good choice for Riceville’s weather?
Yes. Riceville experiences hot, humid summers, sudden thunderstorms, and the occasional hail or high-wind event that rolls up the valley from the Hiwassee River basin. 26- or 29-gauge galvanized steel panels have a Class 4 impact rating for hail, a Class A fire rating, and a wind uplift rating of 140 mph or higher when installed to manufacturer specs. The baked-on Kynar or SMP paint finishes also resist fading in East Tennessee’s strong UV exposure while reflecting heat to lower attic temperatures by as much as 25 °F.
How long can I expect a screw-down panel roof to last?
With proper installation and routine maintenance, a screw-down panel roof in Riceville should last 25–35 years; galvalume panels can push 40 years. The metal itself will usually outlast the neoprene washers under the screw heads, so periodic fastener service is the key determinant of life span. Factory paint warranties range from 25 to 40 years against chalk and fade, and the substrate typically carries a 45- to 50-year rust-through warranty.
What maintenance does an exposed-fastener metal roof require?
1. Fastener inspection every 5–7 years: temperature cycling can loosen screws; they can be re-tightened or replaced with oversized stainless screws and new washers. 2. Sealant checks: replace any cracked caulk at penetrations or panel laps. 3. Debris removal: keep leaves, tree limbs, and acorns off the roof and out of the gutters to prevent moisture traps. 4. Gentle washing: an annual low-pressure rinse with mild detergent will preserve the paint finish. Following this schedule will add a decade or more to the functional life of your roof.
Can a screw-down metal roof be installed over my existing asphalt shingles?
Often, yes. Riceville and McMinn County codes allow a metal-over-shingle retrofit if: (1) the existing roof has no more than one layer of shingles, (2) the deck is structurally sound with no rot or delamination, and (3) local load calculations show the added weight (about 1 lb/ft²) remains within limits. We install a synthetic underlayment or 1×4 purlins over the shingles to create a flat, ventilated surface before fastening the panels. If the shingles are badly curled or there is decking damage, a full tear-off is recommended.
How much does a screw-down panel roof cost in the Riceville area, and what financing or warranties are available?
As of 2024, installed prices in the Riceville–Athens market average $4.50–$6.50 per square foot for 29-gauge panels and $5.50–$7.50 for heavier 26-gauge. Complex roof designs, steep pitches, or tear-offs add to the figure. We offer 12-, 24-, and 36-month same-as-cash financing options through Synchrony and TVA’s eScore program for energy-efficient upgrades. Every project comes with a 5-year workmanship warranty from our crew, plus the manufacturer’s panel and paint warranties (25–40 years).
