How long roof replacement takes
Most residential asphalt re-roofs finish in one to three days on site, but scheduling, permits, and weather stretch the calendar.
How many days does a roof replacement take?
A straightforward asphalt re-roof on a 20–30 square home often completes in one to two days of on-roof work. Complex roofs, tile, or bad weather extend the schedule.
How long from signing to start date?
Busy seasons after hail events can mean two to six weeks of lead time. Permits in some cities add another few days to two weeks.
Can roofing happen in rain?
Crews avoid installing shingles in active rain. They may dry-in with underlayment and return when conditions allow — plan for weather delays.
When can I schedule interior work after re-roof?
Once nails are swept, magnet pass is done, and gutters are reattached. Attic checks for stray fasteners are wise before ceiling repairs.
