What a Full Residential Roof Replacement Involves
A residential roof replacement is the complete removal of your existing roofing system down to the wood decking, followed by inspection and rebuilding of the entire assembly. Unlike a simple repair or an overlay, a full replacement lets us evaluate the condition of the plywood or OSB sheathing, the fascia, and the flashing details that most roof leaks actually originate from. For homes across Alpharetta, Roswell, and Milton built during the 1990s and early 2000s housing boom, this is typically a once-in-25-year investment.
We replace roofs on single-family homes, townhomes, and estate properties throughout our 22-city North Atlanta service area. Most projects in this region are steep-slope roofs at a 6:12 to 9:12 pitch, which is well suited to asphalt shingles, but we also install standing-seam metal for homeowners who want a 40-to-70-year service life and superior performance against wind uplift.
Roofing Materials We Install
Architectural (dimensional) asphalt shingles are our most common installation. They carry a Class A fire rating, wind ratings up to 130 mph when installed to manufacturer spec, and an algae-resistant granule blend that resists the dark Gloeocapsa magma streaking common on shaded North Georgia roofs. Above the shingles we install ridge vents, and beneath them a synthetic underlayment that outperforms traditional felt in heat and tear resistance, plus a self-adhered ice-and-water membrane in valleys and around penetrations.
For homeowners wanting maximum longevity, we install standing-seam and stone-coated steel metal roofing. Metal reflects solar heat, sheds Georgia’s heavy summer rain quickly, and resists the hail that periodically moves through Cherokee and Forsyth counties. We also handle proper attic ventilation balance, intake at the soffit and exhaust at the ridge, which protects the decking from trapped humidity and extends shingle life in our hot, muggy climate.
Our Installation Process and Timeline
Most residential replacements are completed in one to three days depending on roof size, pitch, and the number of layers being removed. We begin by protecting landscaping, siding, and HVAC units with tarps, then tear off the old roofing in sections to limit exposure. After tear-off, we inspect every sheet of decking and replace any that is soft, delaminated, or rotted before the dry-in.
Once the deck is sound, we install the underlayment, drip edge, and flashings, then load and install the shingles or panels from the eaves up. We finish with ridge cap, ridge vent, and a full property cleanup that includes running magnetic rollers over the lawn and driveway to collect stray nails. A final inspection confirms every detail before we consider the job done.
Cost Factors and Warranty Coverage
Replacement cost is driven by roof square footage, pitch and complexity, the number of existing layers, decking repairs, material grade, and access. A simple ranch with a walkable pitch costs far less per square than a steep, cut-up roof with multiple valleys, dormers, and skylights. Choosing metal over architectural shingles raises material cost but lowers lifetime cost through decades of added service life.
Our installations qualify for manufacturer-backed limited lifetime warranties on the shingles themselves, and because we install complete, matched roofing systems to specification, many projects are eligible for enhanced system warranties covering both materials and labor. On top of the manufacturer coverage, Platinum Roofing stands behind its workmanship directly, so a single local company is accountable for the entire roof.
