Roof Replacement in Alpharetta, GA

A full roof replacement in Alpharetta is tear-off to bare decking, a board-by-board inspection, then a complete new roof system installed the same day on most homes and backed by a 50-year labor warranty in writing, where roofing contractors typically offer 1 to 10 years on their own workmanship. Here is exactly what that includes, how long it takes, and how Alpharetta homeowners usually pay for it.

What is included

• Full tear-off of the old roof with disposal. Georgia's residential code can allow new shingles over one existing layer, but we do not roof over old shingles; the layover guide explains why that shortcut costs more later.
• Decking inspection with soft or rotten boards replaced, priced per sheet and shown to you before it is covered.
• Water layers: ice-and-water barrier in valleys and around every penetration, synthetic underlayment across the field. Georgia's code still permits basic No. 15 felt; we install synthetic.
• New metals: drip edge, step and counter flashing, pipe boots. Reused flashing under a new roof is a leading cause of the year-eight leak.
• Ventilation corrected while the roof is open, because a starved attic cooks shingles from below and can void manufacturer coverage.
• GAF architectural shingles installed by a certified crew, then a full cleanup with magnetic sweeps for nails.

How long it takes in Alpharetta

Industry guides such as Angi put a typical asphalt shingle replacement at one to three days, and GAF describes one to two days for an average-size home. Robust Roofing finishes most roofs of average size and complexity in one day: off in the morning and on by evening. Steep, large, or cut-up roofs take longer, and weather gets a vote. When insurance approves a claim we schedule within days, and you watch the schedule in the RoofMap portal. The replacement day guide walks the hours.

What it costs

Size in squares, pitch, the number of layers coming off, decking condition, and the shingle you choose drive the number. After a covered storm loss, your cost is normally the deductible; Alpharetta homeowners paying directly get a written quote from measurements with payment phases spelled out, and a pay-over-time option at checkout for smaller balances. Our Georgia cost guide gives honest ranges, and the financing page explains the options.

Insurance and the replacement

Most of the replacements we do around Alpharetta follow hail or wind. The most recent significant hail on record for Alpharetta fell on July 3, 2026 (1.00 in, quarter size), which is exactly the kind of event that deserves an inspection before the claim window closes. Our licensed adjuster on staff writes the scope, meets your adjuster on the roof, and supplements missed items with photos, and Georgia homeowners will not find insurance help on that level from another roofer. Approval is your carrier's decision under your policy, and we never waive deductibles, which is illegal in Georgia. The storm damage page for Alpharetta covers the claim side.

Warranty

Every replacement carries our 50-year labor warranty on workmanship, in writing. Many contractors cover their own workmanship for only one or two years, according to the National Roofing Contractors Association. Standard shingle warranties from the major manufacturers cover material defects, not installation mistakes, so our labor warranty is the one that answers for how the roof was put on. What it covers, and what voids it, is on the warranty page.
