Asphalt Shingle Roofing Contractor Serving Atlanta, GA

Shingle Roof Repair, Replacement, and New Installation 

What Is Asphalt Shingle Roofing? 

The Most Common Roof in Metro Atlanta, and Why 

Drive through Decatur, Sandy Springs, or Marietta and most of what you see overhead is asphalt shingle roofing. There is a practical reason for that. Georgia summers, pop-up thunderstorms, and heavy tree cover all put real stress on a roof, and asphalt handles that mix at a price most homeowners can actually plan around.

An asphalt shingle is built on a fiberglass mat, coated in asphalt, and surfaced with mineral granules that shed water and shield the shingle from UV exposure. Residential shingles fall into three tiers: three-tab strip shingles, architectural shingles that bond two layers for depth, and luxury shingles built from three layers to replicate cedar shake or slate. With sound installation and working attic ventilation, an asphalt roof in this climate generally serves 20 to 30 years.

KTM Roofing has been installing shingle roofing across the Atlanta metro since 1984, from Alpharetta and Peachtree Corners down through Stockbridge.

Benefits Of Asphalt Shingle Roofing

Why Shingles Still Make Sense for Most Atlanta Homes

Asphalt costs less per square than slate, tile, or standing seam metal, in both material and labor. That keeps a full roof replacement within reach and leaves room for the underlayment, ventilation, and flashing upgrades that actually determine how long the roof lasts.

Most residential shingle roofs go on in one to three days depending on size and complexity. Shorter timelines mean fewer days with a container in your driveway, less exposure if weather moves in mid-project, and less labor carried into the final invoice.

Manufacturers offer shingles that read as cedar shake, slate, or clean architectural lines, in palettes running from near-black through warm browns and grays. That range matters in neighborhoods with HOA color guidelines or where the roofline has to fit an established street.

Shingles weigh a fraction of what slate or clay tile weighs, so framing reinforcement is not part of the conversation. That removes an engineering step and a cost line that heavier materials frequently trigger on older Atlanta homes.

A wind-lifted or cracked shingle can be swapped without disturbing the rest of the roof. Storm damage is often fixable as a targeted repair, which keeps a working roof in service instead of forcing a full replacement after one bad night.

Asphalt Shingle Options We Install

CertainTeed and GAF Products for Atlanta Homes

We install across the CertainTeed and GAF residential lines, from everyday architectural shingles to luxury profiles. Availability and color ranges shift by region and by year, so your consultant brings current samples to the estimate. 

CertainTeed Landmark Architectural shingle, dual-layer construction

Landmark is CertainTeed’s flagship architectural shingle and the one we install most often. Its two-piece laminated build produces the dimensional look of cedar shake, and it carries a UL Class A fire resistance rating along with UL 2218 Class 3 impact resistance. The Landmark PRO tier adds weight and CertainTeed’s Max Def color blends. 

CertainTeed Presidential Shake TL Luxury triple-laminate shingle

Presidential Shake TL uses three laminated layers to build the depth and shadow lines of hand-split cedar. It fits Craftsman, Tudor, and custom homes where the architecture calls for a shake roof without cedar’s upkeep. Residential installations carry a lifetime limited transferable warranty from CertainTeed. 

GAF Timberline HDZ GAF's best-selling residential shingle

Timberline HDZ is the current generation of the Timberline line, replacing the earlier Timberline HD. Its LayerLock design and wide nailing zone improve fastening accuracy during installation, and when paired with four qualifying GAF accessories it becomes eligible for GAF’s WindProven Limited Wind Warranty, which carries no maximum wind speed. 

GAF Grand Sequoia Designer shingle with a wood-shake profile

Grand Sequoia uses oversized, irregular tabs to produce heavy shadow lines and the rugged texture of split shakes. Installed with the required underlayment, it carries a UL Class A fire resistance rating, which makes it a practical option for homes where real cedar is off the table.

Signs Your Asphalt Shingle Roof Needs Repair or Replacement

What to Look For After a Georgia Storm

Shingle roof repair costs far less than replacement when the problem gets caught early. Walk your property after a strong storm, look for these signs from the ground, and get the roof inspected before minor damage becomes an attic leak.

Edges that lift or ripple usually point to heat cycling, trapped attic moisture, or shingles that were nailed incorrectly. Curled shingles catch wind and tear off faster than flat ones.

Cracks open a direct path to the underlayment. Splits often show up where nails were overdriven during the original installation.

Bare spots after a windstorm need attention quickly. Exposed decking absorbs water within days in Atlanta humidity.

Heavy granule loss means the shingle surface is wearing through. Scattered granules after a fresh install are normal. Ongoing accumulation is not.

Interior evidence means water is already past the roof surface. At that stage the deck and insulation may need attention alongside the shingles.

A roof near the end of its service life tends to fail at several points at once. Repeated repairs on an aging roof add up to more than a planned replacement.

Asphalt Shingle Roofing FAQs

Common Questions from Atlanta Homeowners

Most last 20 to 30 years in this climate. Attic ventilation, shingle tier, and installation quality drive that range more than brand does. Dense tree cover and repeated hail can shorten it. 

Often, yes. When damage is localized and the roof still has service life left, a targeted asphalt shingle roof repair is the better call. We recommend replacement when damage is widespread or the roof is near the end of its lifespan. 

That depends on your policy and the cause of loss. Many carriers cover sudden wind or hail damage but exclude gradual wear. We document conditions during the inspection so you have what you need if you file. 

Full roof replacements include a written, transferable 12-year workmanship warranty from KTM, in addition to the manufacturer’s product warranty. We handle the manufacturer registration paperwork after final payment. 

No. Payment is due after the project is finished and invoiced. If a contractor pressures you for money upfront after a storm, treat that as a warning sign.

Why We Install CertainTeed and GAF

Two Manufacturers, One Standard

We are an authorized installer for both. That means our crews train against each manufacturer’s current specifications, and we register your manufacturer warranty on your behalf once the project is closed out.

CertainTeed has manufactured building products for over a century, and its Landmark series has become a reference point for dimensional shingles. GAF, founded in 1886, describes itself as North America’s largest roofing manufacturer, and Timberline is its best-selling residential shingle line.

Carrying two manufacturers instead of one keeps the decision with you. If the color you want lives in a Max Def blend, we specify CertainTeed. If GAF’s wind warranty structure matters more, we build that system instead. Either way the installation follows manufacturer specification, because a warranty is only as good as the work behind it.
