Metal roofing has been part of what we do since we started. In Alabama and across the Gulf South, it’s one of the smartest long-term investments a property owner can make—and one of the most misunderstood. Here’s what we know about metal roofing after years of installing it across Birmingham, Hoover, and the New Orleans metro.
Why Metal Roofing Makes Sense in the Gulf South
The Gulf South is a demanding climate for roofing materials. We deal with summer temperatures that push roof surfaces past 150°F, high humidity year-round, hailstorms, high-wind events from Gulf systems, and the occasional ice event in winter. Asphalt shingles handle all of this adequately for 20–25 years. Metal roofing handles it for 40–70 years.
Beyond longevity, metal roofs reflect solar radiation rather than absorbing it. In a climate where cooling costs are the dominant energy expense, that reflectivity can reduce air conditioning bills by 10–25% depending on the roof color and coating. Standing seam metal in particular—with its concealed fasteners and continuous panels—virtually eliminates the leak points that asphalt shingles develop over time.
Metal Roofing Types: Standing Seam vs. Screw-Down Panel
The most important choice in metal roofing is the panel system. The two main categories are fundamentally different in how they perform and how long they last.
| Feature | Standing seam | Screw-down panel (exposed fastener) |
|---|---|---|
| Fasteners | Concealed (hidden clips) | Exposed screws through panel |
| Lifespan | 50–70 years | 20–40 years |
| Thermal movement | Panels float on clips | Screws restrict expansion; can loosen over time |
| Leak risk | Very low (no exposed fastener holes) | Screw holes can leak as washers wear |
| Cost | Higher upfront | Lower upfront |
| Best for | Residential, commercial, long-term investment | Agricultural, accessory structures, budget projects |
For residential roofing in Birmingham and New Orleans, we almost always recommend standing seam. The concealed fastener system means there are no screw holes that can develop leaks as neoprene washers age—the primary failure mode of exposed-fastener systems in wet climates.
Metal Roofing Materials
Not all metal roofs are the same material. The substrate matters for specific applications:
- Galvalume steel—The most common residential metal roofing substrate. Zinc-aluminum coated steel that resists rust and handles Gulf South humidity well. Available in a wide range of colors.
- Aluminum—Naturally rust-resistant, making it the preferred choice for coastal properties in the New Orleans metro. Lighter than steel, with excellent corrosion resistance to saltwater environments.
- Copper—A premium option with a 100+ year lifespan. Used on historic homes, specialty applications, and high-end residential projects where the aesthetic (and the patina) is part of the design intent.
Metal vs. Asphalt: A Direct Comparison
| Factor | Metal (standing seam) | Asphalt shingles |
|---|---|---|
| Lifespan | 50–70 years | 20–30 years |
| Upfront cost | 2–3x asphalt | Baseline |
| Cooling cost impact | −15–25% in summer | Baseline |
| Hail resistance | High (Class 4 impact) | Moderate (varies by shingle) |
| Wind resistance | Rated to 140+ mph | 110–130 mph typical |
| Maintenance | Minimal | Regular inspection and occasional repair |
| Weight | 1–2 lbs/sq. ft. | 2–3.5 lbs/sq. ft. |
| Lifetime cost | Often lower (one roof vs. two) | Higher (likely replace once in 50 years) |
The upfront cost of metal roofing is higher—typically 2–3 times what asphalt costs per square foot installed. Over 50 years, however, most homeowners who install metal replace their roof once where asphalt homeowners replace it twice. The total cost over a 50-year period often favors metal, particularly when energy savings are factored in.
What Metal Roofing Looks Like on a Birmingham Home
One of the biggest misconceptions about metal roofing is that it looks industrial. Modern standing seam profiles with powder-coat finishes in muted earth tones blend naturally with residential architecture across Birmingham. We’ve installed metal roofing on traditional bungalows in Mountain Brook, Craftsman homes in Hoover, and modern builds in Vestavia Hills—all without it looking out of place.
Color selection and panel profile make a significant difference. We work with homeowners to choose a system that fits the home’s existing architecture, neighborhood character, and HOA requirements where applicable.
Frequently Asked Questions
Is metal roofing loud in rain?
Not when installed correctly over a solid deck with proper underlayment. The noise difference between metal and asphalt on a properly installed system is minimal in a well-insulated home. On open-frame structures (barns, carports, outbuildings), metal roofing is louder because there’s no insulation buffer—but that’s not how residential installations work.
Can metal roofing be installed over existing shingles?
Sometimes, with conditions. Most jurisdictions allow one layer of roofing over existing shingles. Adding a second layer adds weight and prevents proper inspection of the decking. Our standard recommendation is to tear off existing shingles so we can inspect the deck and address any rot or moisture damage before installing the new roof. An unseen deck problem under new metal roofing will become a very expensive problem later.
Does metal roofing attract lightning?
No more than any other roof material. Lightning strikes the highest point in an area, regardless of what it’s made of. Metal roofing doesn’t make your home a more attractive target. And if it is struck, metal conducts and disperses the energy rather than igniting, making it safer than wood in that specific scenario.
