FAQs
How does metal roofing perform in the high winds common to Signal Mountain?
Properly engineered metal roofing is one of the most wind-resistant systems available. Interlocking panels, continuous clips, and high-strength fasteners create a monolithic surface that resists uplift and prevents shingle blow-off, a frequent problem on the mountain’s ridges. In lab and field tests, quality metal roofs have withstood sustained winds of 140 – 200 mph—well above the gusts typically seen during severe thunderstorms or remnants of tropical systems that reach Signal Mountain.
What wind ratings do your metal roofing systems carry?
Our standing-seam and metal shingle lines are tested to UL 580 Class 90, UL 1897, and ASTM E1592 standards. Several profiles also carry Miami-Dade NOA approvals, certifying performance in winds up to 180 mph. We pair each project with the panel profile and gauge that best matches the 110 mph basic wind speed required by Hamilton County’s adoption of the International Residential Code, so your roof is not just code-compliant but exceeds local requirements.
Will a metal roof make my home noisier during wind storms?
No. Modern metal roofing is installed over solid decking (usually 5⁄8-in. plywood or OSB), synthetic underlayment, and often an additional self-adhered ice & water shield at the eaves. This multi-layer assembly, combined with your attic insulation, absorbs sound better than older exposed-fastener or barn-style metal roofs. Many customers report their homes are actually quieter during high winds because there are no loose shingles flapping or lifting.
What installation techniques do you use to secure metal panels against uplift?
We follow manufacturer engineering tables for clip spacing, use stainless or coated fasteners with a 3,000-hr salt-spray rating, and place extra screws at eaves, ridges, and gable ends where wind pressure is highest. Panels are stagger-seamed to distribute load, and continuous Z-closures with butyl sealant lock panels under hips and ridges. All edge metal is hemmed and screwed into blocking, creating a clean look and a mechanical lock that resists peel-back.
Are there local building codes or HOA guidelines in Signal Mountain that affect metal roof installations?
Hamilton County enforces the 2018 IRC/IBC with a 110 mph Exposure C wind map. A building permit and mid-roof inspection are required, and valley, flashing, and underlayment details must follow manufacturer ESR reports. If you live in an HOA such as Old Towne or Fox Run, color and panel style (e.g., 1-in. standing seam versus corrugated) may need architectural approval. We handle the permit paperwork, provide wind-uplift certification letters, and attend HOA meetings on your behalf if needed.
How does the cost of a wind-rated metal roof compare to asphalt shingles over time?
Installed cost is usually 2–3 × that of architectural shingles, but metal’s 40- to 70-year service life means you’ll avoid two to three re-roof cycles. Add in reduced maintenance, insurance discounts for UL Class 4 impact resistance, and potential energy savings from reflective coatings, and many Signal Mountain homeowners see a lower total cost of ownership within 15–20 years. A metal roof can also boost resale value, particularly in wind-exposed neighborhoods where buyers appreciate the durability.
