How much does a roof replacement cost in Johns Creek?

Most asphalt shingle replacements on a typical single-family home run several hundred dollars per square (100 sq ft) of roof, with total project costs commonly landing in the low-to-mid five figures depending on roof size, pitch, decking condition, and shingle grade. Metal or tile roofing costs more per square than architectural asphalt shingles. Get itemized quotes from at least two or three contractors before comparing.

How often does a roof need to be replaced?

Standard 3-tab asphalt shingles typically last 15-20 years, while architectural (dimensional) shingles often last 25-30 years with proper attic ventilation. Metal roofing can last 40-50 years or more. Storm damage, poor ventilation, or improper prior installation can shorten these timelines significantly.

What should I expect during the replacement process?

Expect the crew to tarp landscaping, strip old materials, inspect and replace any rotted decking, install new underlayment and flashing, lay new shingles, and haul away debris, usually within one to three days for an average-size roof. A magnetic sweep for nails and a final walkthrough should be part of the job before the crew leaves.

How can I judge the quality of a roofing contractor's work?

Look for straight, evenly spaced shingle courses, properly sealed flashing at valleys and penetrations, adequate ridge and soffit ventilation, and a clean job site afterward. Ask to see photos of completed jobs and check whether the contractor offers both a manufacturer warranty and their own workmanship warranty in writing.

Roof Replacement in Johns Creek

A full roof replacement means stripping the existing shingles, felt, and flashing down to the deck, repairing or replacing damaged sheathing, installing new underlayment and ice/water barrier at valleys and eaves, then laying new shingles, ridge caps, and flashing around chimneys, vents, and skylights. In Johns Creek, that job usually runs a few days depending on roof size and pitch, and it's a bigger undertaking than a repair or a few patched shingles after a storm. We've gathered 6 roofing contractors serving the area who handle this kind of work.

Before you sign a contract, ask about the manufacturer certifications they hold (GAF Master Elite, CertainTeed SELECT ShingleMaster, and similar programs), because those often unlock stronger warranties than a standard installer can offer. Get a written scope that spells out decking replacement pricing per sheet, underlayment type, ventilation plan, and cleanup terms. Confirm they're pulling permits where required and carrying current liability and workers' comp coverage, and ask how they handle insurance claims if your job is storm-related.

Our scoring weighs how contractors are reviewed over time, how they respond to customer concerns, and signals of licensing and consistency across jobs, not just a star average.
