FAQs
What is a standing-seam metal roof and how is it different from traditional exposed-fastener metal panels?
Standing-seam systems use continuous metal panels that lock together with raised vertical seams ("standing" seams). All fasteners are concealed beneath the seams, so there are no exposed screws that can loosen, back out, or leak over time. Exposed-fastener roofs (also called screw-down or AG panels) leave the screw heads visible on the surface, which creates thousands of potential leak points. The concealed-fastener design of standing-seam roofs provides superior weather resistance, a cleaner appearance, and longer service life.
How long can I expect a standing-seam metal roof to last in Whitwell’s climate?
Properly installed standing-seam panels made from 24- or 26-gauge galvanized or galvalume steel typically last 40–70 years in our humid subtropical climate. The baked-on Kynar 500®/PVDF paint system resists chalking and fading for 30+ years, and the concealed fasteners prevent the premature gasket failures common with screw-down panels. Routine inspections and minor maintenance can push the service life toward the upper end of that range.
Will a metal roof be noisy when it rains or hails?
When installed over solid decking with high-quality underlayment (and often a layer of insulation), a standing-seam roof is only marginally louder than an asphalt-shingle roof—usually by 5 decibels or less. Most homeowners in Whitwell report that indoor noise is not an issue because the attic insulation and drywall ceilings absorb much of the sound. If additional sound dampening is desired, we can add a high-density acoustic underlayment.
What maintenance does a standing-seam roof require?
Standing-seam roofs are low-maintenance, but not maintenance-free. We recommend: • Annual visual inspections (or after severe storms) to check for debris, loose trim, or sealant wear. • Clearing leaves and branches from valleys and gutters to maintain proper water flow. • Washing pollen, dirt, or algae off the panels with a garden hose and mild detergent if buildup appears. • Re-sealing exposed terminations (ridge caps, penetrations) every 15–20 years. • Replacing any damaged snow guards or clips promptly. Following these steps preserves the finish warranty and helps the roof reach its full lifespan.
Can a standing-seam roof be installed over my existing shingle roof?
In many cases, yes. Building codes allow metal to be installed over a single layer of asphalt shingles if the decking is sound and local weight limits are observed. We place a synthetic underlayment or a vented spacer between the shingles and metal panels to create a smooth, moisture-resistant surface. However, if the shingles are curled, if there are more than two layers, or if the decking shows rot, we will recommend a tear-off so the new roof has a solid, warranty-compliant substrate.
What does a standing-seam roof cost in the Whitwell area?
Installed pricing typically runs $9–$14 per square foot for standard 24-gauge steel panels, including trim and underlayment. Factors that influence cost include: panel material (steel vs. aluminum vs. copper), roof complexity (number of valleys, dormers, and penetrations), panel width/profile, decking repairs, and whether a tear-off is required. While the upfront cost is higher than asphalt shingles, the 2–3-times longer lifespan and energy savings often make standing-seam the most economical choice over the life of the home.
