New Roof Installation in Atlanta, GA

What Does a New Roof Installation Involve?

A new roof installation isn't just nailing down shingles. It's a complete system: deck preparation, underlayment, flashing, ventilation, and the shingles themselves. We start by tearing off the old layers down to the wood deck. That lets us inspect for rot, damage, or weak spots. In Atlanta, where humidity can accelerate wood decay, this step is critical. We replace any compromised decking with 7/16-inch OSB or plywood, then install a synthetic underlayment—I prefer Owens Corning DeckDefense or GAF FeltBuster for their tear resistance and water-shedding ability. Next comes drip edge along all eaves and rakes, required by Georgia's IRC 2015 code. We install step flashing at walls, pipe boots with rubber gaskets, and valley flashing that's woven or closed-cut, depending on the shingle. Finally, we lay the shingles, ridge cap, and venting—either ridge vents or box vents, calculated to give you 1 square foot of net free vent area per 300 square feet of attic space.

How Much Does a New Roof Cost in Atlanta?

For a typical 2,000-square-foot home in Atlanta, a new asphalt shingle roof runs between $8,000 and $16,000, depending on pitch, complexity, and shingle grade. Architectural shingles like GAF Timberline HDZ cost $4.50 to $6.00 per square foot installed. Premium options like Owens Corning Duration STORM (Class 3 impact-rated) add $1.00–$1.50 per square foot. Metal roofing, standing seam or screw-down, ranges from $12 to $20 per square foot. Labor in Atlanta averages $150–$250 per square (100 square feet). I always provide a detailed line-item quote—no hidden fees for tear-off, dumpster rental, or permits. Permit fees in most metro Atlanta counties run $75–$150 for a residential re-roof. If structural repairs are needed—like replacing trusses or rafters—engineered drawings may be required, adding $500–$1,000 to the project.

Signs You Need a New Roof Installation

Is it time to replace your roof?

If your roof is over 20 years old, has widespread damage, or leaks in multiple spots, a full replacement is smarter than patching. Here are the warning signs specific to Atlanta's climate.

• Missing or curled shingles after storms—common after our severe thunderstorms and wind events.
• Water stains on interior ceilings or walls—indicates a leak that's already penetrated the deck.
• Granules in gutters or downspouts—signals shingle aging from UV and heat exposure.
• Visible daylight through roof boards—means the deck or underlayment has gaps or rot.
• Granule loss on south- and west-facing slopes—accelerated by Atlanta's intense summer sun.
• Leakage at valleys—often from debris buildup and heavy rain channeling water.
• Ice damming in northern GA—from snow and freeze-thaw cycles, causing water backup under shingles.
• High energy bills—poor attic ventilation and insulation, often tied to roof age.

Step-by-Step Process: How We Install Your New Roof

1. Inspection and Estimate—I personally inspect your roof, attic, and deck. We discuss material options, color, and budget. I provide a written estimate within 24 hours, including permit costs.
2. Material Delivery and Prep—We order shingles, underlayment, flashing, and venting from local suppliers (GAF, Owens Corning, CertainTeed). We protect your landscaping with tarps and set up a dumpster for tear-off debris.
3. Tear-Off and Deck Repair—Our crew strips all old shingles and underlayment down to the deck. We replace any rotted or damaged plywood. This takes 1–2 days for an average home.
4. Underlayment and Flashing Installation—We roll out synthetic underlayment, secure it with cap nails, and install drip edge, step flashing, pipe boots, and valley flashing. This is where water protection starts.
5. Shingle Installation—We nail shingles per manufacturer specs (4–6 nails per shingle, depending on slope). For GAF Timberline HDZ, we use the patented nailing zone. Ridge cap shingles are installed last, with ridge vent for airflow.
6. Final Inspection and Cleanup—We walk the roof, check all flashings, and use magnets to pick up stray nails. We clean gutters, sweep the driveway, and do a final walk-through with you. Total time: 2–5 days for most homes.

Material Options for Atlanta Homes

I recommend three primary shingle lines that perform well in our climate. Owens Corning Duration STORM shingles have a Class 3 impact rating—ideal for hail-prone north Georgia. They also feature SureNail technology for better wind resistance. GAF Timberline HDZ shingles are alga-resistant (important for Atlanta's humidity) and wind-rated to 130 mph. They come with a 30-year warranty and a 10-year algae stain warranty. CertainTeed Landmark Pro shingles are laminated, offer a 30-year limited warranty, and have a 110-mph wind rating. For metal roofs, I install standing seam panels in steel or aluminum, with hidden fasteners and a 40-year paint warranty. Metal reflects heat, reducing cooling costs in our hot summers, but costs more upfront.

Local Climate Considerations for Your New Roof

Atlanta's climate is tough on roofs. High humidity requires proper attic ventilation to prevent wood rot and mold. I calculate vent area using the 1:300 rule—1 square foot of vent for every 300 square feet of attic space. Hail storms in north Georgia demand impact-resistant shingles; I often recommend Class 3 or Class 4 for that reason. The urban heat island effect in areas like Buckhead or Midtown accelerates asphalt aging, so I prefer lighter-colored shingles or metal to reflect UV rays. Severe thunderstorms with 60+ mph winds are common—our nailing patterns and wind-rated shingles handle that. And in northern metro counties like Cherokee or Forsyth, snow and freeze-thaw cycles can cause ice damming, so I install ice-and-water shield at eaves and valleys.

Insurance and Warranties

If your roof was damaged by a storm, your homeowner's insurance may cover part or all of the replacement. I work directly with your adjuster, provide a detailed scope of loss, and help you navigate the claims process. I also offer a 5-year workmanship warranty on all installations, covering leaks due to installation errors. Manufacturer warranties vary: GAF Timberline HDZ has a 30-year non-prorated warranty (including labor reimbursement for the first 10 years), CertainTeed Landmark Pro has a 30-year limited warranty, and Owens Corning Duration STORM has a 30-year warranty with a 10-year algae stain warranty. Metal roofs come with 40-year paint and 30-year substrate warranties.
