What Makes Metal Roofing Different from Asphalt?
Metal roofs aren't just another material swap. They change how your home handles heat, rain, and time. In Atlanta, where we see everything from 95-degree humidity to sudden ice storms, metal roofing offers real advantages.
Steel vs. Aluminum vs. Copper
Most Atlanta homeowners choose between steel and aluminum. Steel is stronger and more affordable — expect to pay $7 to $12 per square foot installed for galvanized steel. Aluminum runs $9 to $15 per square foot but won't rust, which matters in our humid summers. Copper is premium at $15 to $25 per square foot, developing a patina over time. We typically recommend 26-gauge steel or 0.032-inch aluminum for residential projects.
How Long Does a Metal Roof Last?
A properly installed metal roof lasts 40 to 70 years. Compare that to asphalt shingles, which average 15 to 20 years in Atlanta's climate. You'll likely replace your metal roof once — if ever. Most manufacturers offer 30- to 50-year warranties, and the paint systems carry 20- to 30-year fade warranties.
Does Metal Roofing Save Money on Energy?
Yes, if you choose the right product. Cool-coated metal roofs reflect up to 70% of solar radiation. In an Atlanta attic that regularly hits 140 degrees, that can cut cooling costs by 10% to 25%. We install standing seam panels with hidden clips that allow for thermal expansion without leaks.
How We Install a Metal Roof — Step by Step
1. Tear-Off and Deck Prep
We remove the existing roof layers down to the plywood deck. In Atlanta, we often find rotted decking from years of trapped moisture. We replace any damaged sheathing with 5/8-inch CDX plywood. This step takes 1 to 2 days for a typical 2,000-square-foot home.
2. Underlayment and Ice & Water Shield
We roll out a synthetic underlayment rated for high heat (ASTM D1970). Along eaves, valleys, and around all penetrations, we install ice and water shield — even though Atlanta doesn't get heavy ice dams, this prevents wind-driven rain from backing up under the panels.
3. Flashing and Trim Installation
Flashing is where most metal roof failures happen. We fabricate custom flashing for chimneys, skylights, and pipe boots on-site using a portable brake. All flashing is pre-painted to match your panel color. We install continuous ridge vent with weather-resistant baffles.
4. Panel Installation
For standing seam, we use hidden clips that allow the panels to expand and contract with temperature changes — critical in Atlanta's 80-degree temperature swings. Panels are mechanically seamed with a handheld seamer for a watertight lock. We stagger seams by at least 3 feet to prevent water penetration.
5. Ridge Cap and Trim Completion
We install the ridge cap with raised seams to allow ventilation, then seal all exposed fasteners with butyl tape. Finally, we clean the job site with a magnet sweeper — metal shavings can rust on your lawn or driveway.
Timeline
A typical 2,000-square-foot metal roof takes 5 to 8 days. Standing seam takes longer than exposed fastener panels because of the seaming process. We'll give you a exact timeline after our on-site measurement.
What Does Metal Roofing Cost in Atlanta?
You can expect:
- Exposed fastener (screw-down) panels: $5 to $8 per square foot installed
- Standing seam (hidden fastener): $8 to $15 per square foot installed
- Metal shingles (stone-coated steel): $10 to $18 per square foot installed
For a 2,000-square-foot roof, that's $16,000 to $36,000 total. Yes, it's more than asphalt's $8,000 to $14,000. But factor in one replacement cycle: over 40 years, you'd replace asphalt twice. Metal wins on lifetime cost.
Does insurance cover metal roofing?
If your roof is damaged by hail or wind, your homeowner's policy typically pays for replacement. Metal roofs often qualify for discounts on wind and hail coverage. We'll help you document the damage and work with your adjuster.
Can You Walk on a Metal Roof?
Yes, but you need to know where to step. Standing seam panels can dent if you walk on the flat areas. We install walk pads — rubber mats that adhere to the panel — near chimneys and skylights where you might need access. Never walk on a metal roof when it's wet; the surface becomes slick.
Does Metal Roofing Rust?
Galvalume steel — the standard for residential metal roofing — has a zinc-aluminum coating that prevents rust for decades. Scratches from branches or hail can expose bare steel, but most panels have a Kynar 500 paint finish that resists chipping. We've seen 20-year-old metal roofs in Atlanta with no rust. Aluminum won't rust at all.
What About Noise in Rain?
With solid decking, underlayment, and attic insulation, a metal roof is no louder than asphalt. The old myth about drumming rain comes from barns with no decking underneath. We install over a solid plywood deck with a minimum of R-30 attic insulation, which deadens sound effectively.
Do You Offer Financing for Metal Roofs?
Yes. We partner with two local lenders offering 0% APR for 12 months and fixed-rate options up to 10 years. Most homeowners finance part of the cost. Call (404) 474-0372 to discuss terms and get pre-approved in about 10 minutes.
