How Long Does a Roof Replacement Take?
From one day to one week — what determines how long your roof replacement will take, and what to expect during the process.
You've signed the contract. Materials are ordered. Now the question everyone asks: how long is this going to take?
The Quick Answer
| Roof Type | Typical Timeline | |---|---| | Standard asphalt shingles (simple roof) | 1 day | | Standard asphalt shingles (complex roof) | 1-2 days | | Large or steep roof | 2-3 days | | Metal roofing | 3-5 days | | Tile or slate | 5-7+ days |
Most residential asphalt shingle replacements in the Atlanta area are completed in one to two days. A straightforward 20-25 square gable roof with standard pitch? An experienced crew can often tear off and install in a single day.
What Makes It Take Longer
Roof size is the most obvious factor. A 15-square ranch is faster than a 35-square colonial. Bigger roof = more material = more time.
Steep pitch slows everything down. Crews on a walkable 4:12 pitch move much faster than on a steep 8:12 or 10:12 roof that requires harnesses, toe boards, and extra caution.
Complexity — dormers, valleys, hips, skylights, chimneys — each adds time. A simple two-plane gable is the fastest. A multi-hip roof with three dormers, a chimney, and skylights adds hours of detail flashing work.
Decking repair is the wild card. If your crew tears off old shingles and finds extensive rotted plywood, that decking has to be replaced before new materials go on. A few sheets adds 30 minutes. Twenty sheets can add half a day.
Weather is always a factor in Atlanta. Afternoon thunderstorms are common spring through fall. A responsible crew won't start tear-off if rain is likely. Weather delays can push a one-day job into two.
What Happens Each Day
Here's the typical sequence for a standard residential replacement:
Day 1 Morning: Setup and Tear-Off
- Crew arrives (usually 7-8 AM)
- Tarps go down to protect landscaping, siding, and A/C units
- Dumpster is positioned
- Tear-off begins from the ridge down
- Old shingles, underlayment, and debris are removed to the deck
- Decking is inspected — any rotted or damaged sheets are replaced
Day 1 Midday: Dry-In
- New underlayment (synthetic or felt) is rolled out
- Ice and water shield is applied at eaves, valleys, and around penetrations
- New drip edge is installed at the perimeter
- At this point, your house is waterproof even without shingles — this is the "dry-in" milestone
Day 1 Afternoon: Installation
- Starter strip goes down at the eaves
- Shingles are installed from bottom to top
- Flashing is woven in at valleys, walls, pipes, chimneys, and skylights
- Ridge cap is installed last
Day 1 or 2: Cleanup
- All debris cleared from roof, gutters, and ground
- Magnetic nail sweep of yard, driveway, and surrounding area
- Final walkthrough with homeowner
What You Should Do During the Process
Move your cars out of the driveway and away from the house. Nails and debris will fall.
Protect your attic. Dust and small debris can filter through during tear-off. Cover anything stored in the attic directly below the roof.
Expect noise. Tear-off is loud. Nail guns are loud. It starts early and goes all day. If you work from home, noise-canceling headphones are your friend.
Keep pets inside or away from the work area. Nails on the ground are a real hazard.
Be reachable. If unexpected issues come up (rotted decking, damaged flashing that needs more work), your contractor needs to reach you for approval before adding cost.
When to Worry
A one or two day delay from weather is normal. But these are signs something might be off:
- Crew doesn't show up on the scheduled day with no communication — Call your contractor immediately.
- Work stops mid-job for more than a day (without weather cause) — Get an explanation.
- Different crew shows up than discussed — Confirm with your contractor that this was planned.
- No one does a walkthrough at the end — Request one before making final payment. This is your chance to flag anything that doesn't look right.
The Bottom Line
A residential roof replacement is disruptive for a day or two, but it's a fast process when done by an experienced crew. The best thing you can do is be prepared, be available, and trust the process — while keeping an eye on the details.
