Typical Timelines by Roof Type
- Asphalt shingles, simple roof: 1 day
- Asphalt shingles, average home: 1 to 2 days
- Asphalt shingles, large or complex: 2 to 3 days
- Standing-seam metal: 3 to 5 days
- Tile or slate: 5 to 10 days
- Wood shake: 3 to 5 days
If your roof is asphalt shingles on a typical suburban home, plan for two days and be pleasantly surprised if they finish in one.
Day 1: Tear-Off and Decking
Morning: The crew arrives, usually between 7 and 8 AM. They set up tarps over landscaping and AC units, position the dumpster, and protect siding and windows. Then tear-off begins: old shingles, underlayment, and flashing come off in sections, working from top to bottom.
Midday: With the decking exposed, the crew inspects every sheet of plywood. Rotted or damaged sections get replaced, typically at $2 to $5 per square foot. This is the most common "surprise" in roofing. Your roofer should photograph any damage and confirm the extra cost with you before proceeding, not after.
Afternoon: Ice-and-water shield goes down on eaves and valleys, synthetic underlayment covers everything else. Here is the reassuring part: by end of day one, your roof is fully weatherproof even with zero shingles installed. An overnight rainstorm is not a disaster at this stage.
Day 2: Shingles and Flashing
Morning: Drip edge and starter shingles go on first, then the field shingles. This is the fastest phase of the project. An experienced crew lays 2 to 4 squares per hour, and the transformation is dramatic. By lunch, your house looks like it has a new roof, because it mostly does.
Afternoon: Ridge caps, valley flashing, pipe boots, and chimney flashing get installed and sealed. Ridge ventilation goes in. The roof looks finished by late afternoon, and structurally it nearly is.
Day 3 (If Needed): Details and Cleanup
Final flashing touches, gutter reattachment check, and then the part that separates good roofers from sloppy ones: thorough cleanup. That means a magnetic nail sweep of your entire property (twice, not once), gutter cleanout, and a landscape walkthrough. The project manager should walk the roof and the ground with you before anyone leaves.
The 5 Things That Cause Delays
- Weather. Rain, high winds, or extreme heat can pause work safely. Build a 2-day buffer into your expectations rather than planning around a perfect forecast.
- Hidden deck damage. Extensive rot discovered during tear-off takes time to replace properly. Rushing this step guarantees future problems.
- Material delivery problems. Special-order shingle colors or materials that did not arrive on time. Confirm delivery dates before tear-off day.
- Permit and inspection scheduling. Some municipalities require a mid-project inspection before shingles go on. Your roofer should have this scheduled in advance.
- Undersized crew. A 3-person crew takes roughly twice as long as a 6-person crew. Ask about crew size when you compare quotes. It directly affects your timeline.
How to Prepare Your Home (Do This the Night Before)
- Move all vehicles away from the house and out of the driveway. Falling debris is guaranteed.
- Cover everything in the attic with tarps. Fine dust and small debris will fall through during tear-off.
- Take pictures and decorations off the walls. Hours of hammering vibrates the whole house.
- Secure pets in the quietest room, or better yet, board them for tear-off day. The noise is genuinely distressing for animals.
- Give your neighbors a heads-up. It is courteous, and it prevents noise complaints that can slow the crew down.
- Unlock side gates and clear driveway access so the dumpster and material deliveries have a clear path.
