What is the average time to replace a roof?
Short answer. Most asphalt shingle roofs on single-family homes are replaced in one to two days, and many average-sized roofs are finished in a single day by a full crew. Steep, large or cut-up roofs, extra layers to tear off, rotted decking, or weather delays can stretch it to three days or more, and metal and tile roofs take longer.
What happens on the day
- Early morning setup: protecting landscaping, placing the dumpster or trailer, and laying tarps.
- Tear-off by section, with the decking inspected and bad sheets replaced.
- Dry-in with underlayment as each section is opened, so the house is never left exposed.
- Shingles, flashing, boots, vents and ridge caps.
- Cleanup, including magnetic sweeps for nails, and a final walk-around.
What makes it take longer
- Size: big roofs simply take more hours.
- Pitch: steep roofs require harnesses and roof jacks and slow every task.
- Complexity: many valleys, dormers, chimneys and skylights.
- Layers: two layers of old shingles to strip.
- Decking: widespread rot that needs replacing.
- Weather: Georgia's summer pop-up storms can force crews to dry in and pause.
- Access: steep driveways or tight lots that slow material handling.
The whole timeline
The install day is the short part. Inspection, estimates, any insurance approval, HOA approval, the permit, material ordering and scheduling can take days to weeks, longer after a big storm when every roofer is busy. Robust Roofing's replacement day guide walks through the day hour by hour.
