FAQ

- Standing seam (hidden fasteners), corrugated/ribbed panels (exposed fasteners), metal shingles/tile (interlocking

profiles), and stone-coated metal. Materials include galvanized or galvalume steel, aluminum, copper, and zinc.

2) How long does a metal roof last?

- Typically 30–70+ years depending on material, finish, and maintenance. Steel with good coatings often lasts 30–50

years; aluminum and copper can last longer.

3) How much does metal roofing cost?

- Very approximate installed cost: $3–12+ per sq ft (wide range driven by material, profile, labor, location). Standing seam

and premium metals (copper) are at the high end. Get local quotes.

4) Is metal roofing more expensive than asphalt shingles?

- Upfront yes — often 2–3× (or more) the cost of basic asphalt shingles. Lower lifecycle costs due to longevity and low

maintenance can offset higher initial cost.

5) Will a metal roof save on energy bills?

- Yes, reflective finishes and light colors can lower cooling costs. Cool-coating options improve reflectivity and emissivity.

Savings depend on climate and insulation.

6) Are metal roofs noisy in rain or hail?

- Proper underlayment, insulation, and attic airspace substantially reduce noise. Metal roofs are not significantly noisier

than shingles when installed correctly.

7) Do metal roofs dent from hail?

- Some metal roofs can dent (especially softer metals or thin gauges). Thicker gauges, structural profiles, and certain

materials (aluminum alloys, steel with stiff ribs) resist denting better.

8) Will a metal roof rust?

- Modern metal roofs use corrosion-resistant coatings (galvalume, zinc, paint systems) and aluminum/copper do not

rust. Coastal or industrial locations need appropriate alloys/coatings and maintenance.

9) Can you install metal roofing over existing shingles?

Yes in some cases.
