FAQs
What are hidden-fastener metal panels and how do they differ from exposed-fastener systems?
Hidden-fastener panels (also called standing-seam or concealed-fastener panels) are manufactured with interlocking seams that snap or mechanically lock together, hiding the screws beneath the ribs. Because the fasteners never penetrate the weather-surface, the system is more watertight, wind-resistant, and visually clean than exposed-fastener panels, which rely on visible screws and rubber washers that can loosen over time.
Why are hidden-fastener metal roofs and siding a smart choice for Farragut’s climate?
Farragut experiences humid summers, occasional heavy rain, hail events, and strong winds off the Tennessee River. Hidden-fastener metal panels are engineered to expand and contract without stressing the fasteners, so they stay watertight during rapid temperature swings. The raised seams channel water away quickly during downpours, 24–26 ga. steel or .032 aluminum options resist hail dents, and most panels carry wind-uplift ratings of 120–150 mph—well above local code requirements.
How long can I expect a hidden-fastener metal roof or wall system to last?
Properly installed concealed-fastener roofs routinely last 40–70 years—two to three times longer than asphalt shingles. The substrate is galvanized or Galvalume® coated for rust resistance, and Kynar®/Hylar® PVDF paint systems come with 30–40-year fade and chalk warranties. Wall applications see even less wear and can last the lifetime of the building with only minimal upkeep.
Will a hidden-fastener metal roof help lower my energy bills?
Yes. Cool-roof pigments in today’s PVDF finishes reflect 25–70 % of solar heat, keeping attic temperatures 10–15 °F cooler in summer. When paired with proper insulation and venting, homeowners in Farragut typically see 10–25 % savings on cooling costs. In winter, the continuous metal surface and concealed fasteners reduce air infiltration, helping retain heat.
How does the installation process work and will it disrupt my daily routine?
Our factory-trained crew first inspects the decking, installs underlayment and high-temp ice-and-water shield at eaves and valleys, then lays each panel from eave to ridge, locking seams with hidden clips. For a 2,500 sq ft roof, installation usually takes 2–4 days, weather permitting. Because panels are pre-cut and mechanically seamed on site, noise and debris are minimal, and most customers stay comfortably in their homes or keep businesses open during the project.
What maintenance is required to keep hidden-fastener metal panels looking and performing their best?
Maintenance is simple: rinse the panels with a garden hose or mild detergent once or twice a year to remove pollen and grime; keep gutters free of leaves; and visually inspect flashings after severe storms. Unlike exposed-fastener roofs, there are no screws to re-tighten or replace. If sealant at penetrations ever ages, it can be spot-recaulked in minutes. With these basic steps, your roof or siding will retain its curb appeal and full weather protection for decades.
