The Complete Metal Roofing Guide
Metal roofing has become one of the fastest-growing segments of the roofing industry — and for good reason. With lifespans of 40–70 years, superior energy efficiency, and exceptional resistance to wind, hail, and fire, metal roofs offer long-term value that far exceeds traditional asphalt shingles. This guide covers everything you need to know before making the switch.
Types of Metal Roofing
Metal roofing comes in several materials and styles, each with different price points, appearances, and performance characteristics.
- →Standing Seam Steel — Most popular, concealed fasteners, 40–60 year lifespan, $8–$14/sq ft installed
- →Aluminum — Lightweight, corrosion-resistant, ideal for coastal climates, $12–$18/sq ft installed
- →Metal Shingles — Mimics traditional looks, easier installation, $7–$12/sq ft installed
- →Copper — Premium choice, 100+ year lifespan, develops a patina, $25–$40/sq ft installed
- →Corrugated Steel — Budget option, common on agricultural buildings, $5–$10/sq ft installed

Energy Efficiency Benefits
According to the U.S. Department of Energy, metal roofs can reduce cooling costs by 10–25% compared to dark asphalt shingles. Reflective metal roofing is classified as a "cool roof" by the EPA and Energy Star program, meaning it reflects more solar energy and absorbs less heat. In warm climates, this translates to significant savings on air conditioning bills year over year.

- ✓Ask for examples of past metal roof projects in your area
- ✓Confirm they carry manufacturer certifications (GAF, Owens Corning, etc.)

Frequently Asked Questions
How long do metal roofs last?
Metal roofs typically last 40 to 70 years depending on the material. Steel roofs last 40–60 years, aluminum 50+ years, and copper can last over 100 years. Compare this to asphalt shingles which last 20–30 years. Most metal roofs come with 30–50 year manufacturer warranties and are highly resistant to wind, hail, and fire.
Are metal roofs noisy in rain?
Modern metal roofs installed with proper insulation and solid sheathing are no noisier than asphalt shingles during rain. The noise concern mainly applies to metal roofs installed over open framing (like on barns). Residential metal roofs typically include underlayment and insulation that absorbs sound, making them comparable in noise level to other roofing materials.
Can a metal roof be installed over existing shingles?
In many cases, yes — metal roofing can be installed over one existing layer of asphalt shingles, saving the cost and labor of removal. However, this depends on local building codes, the condition of the existing roof structure, and the metal roofing product chosen. Standing seam systems in particular work well over existing shingles. Always have a professional inspect the existing structure before deciding.
What is the best type of metal roofing?
The best metal roof depends on your climate, budget, and aesthetics. Standing seam metal roofing offers the best performance and longevity with concealed fasteners and minimal maintenance. Metal shingles mimic traditional looks while offering durability. Steel is the most affordable, aluminum is lightweight and corrosion-resistant (ideal for coastal areas), and copper is the premium choice for historic or luxury homes.
Do metal roofs increase home value?
Yes. Studies show metal roofs can increase home resale value by 1–6% compared to homes with asphalt shingle roofs. The ROI is particularly strong in markets where durability and energy efficiency are valued. Metal roofs also lower homeowners insurance premiums in many states due to their superior wind and fire resistance ratings.
