A typical asphalt shingle re-roof takes 1-3 days for an average home once the crew is on site, but the full project — from first contractor call to final inspection — usually runs 4-8 weeks. This article walks through every stage: estimate phase (1-2 weeks), permit and material order (1-2 weeks), tear-off day (Day 1), deck inspection and underlayment (Day 1-2), shingle install (Day 2-3), cleanup and final walkthrough (Day 3), and inspector sign-off (Week 4+).
A straightforward residential reroof is a one to three day job on site. The whole process from first quote to final inspection is normally two to six weeks, and most of that is scheduling rather than work.
| Stage | Typical duration | What is happening |
|---|---|---|
| Quotes | 1 – 2 weeks | Three contractors measure and price against the same scope |
| Contract and permit | 3 days – 2 weeks | Signing, deposit, permit application |
| Material delivery | 1 – 3 days before | Boom delivery onto the roof or a ground stack |
| Tear-off | Half a day – 1 day | Strip, pull nails, inspect the deck |
| Deck repairs | Same day | Replace whatever is soft or rotten |
| Dry-in | Same day as tear-off | Ice barrier, underlayment, drip edge |
| Install | 1 – 2 days | Starter, field, flashing, ridge and vents |
| Cleanup | Same day | Magnet sweeps, dumpster removal |
| Final inspection | 1 – 2 weeks after | Local authority signs off the permit |
One to three days on site for a straightforward residential reroof. The whole process from first quote to final inspection is normally two to six weeks, and most of that is scheduling rather than work.
Weather above all — nothing gets stripped with rain forecast. Then steep pitch, difficult access, complexity, bad decking found after tear-off, peak season booking, and insurance claim processing.
Move vehicles well clear, take pictures off walls, cover things in the attic, cut back overhanging branches, clear the perimeter, tell the neighbours, and keep pets indoors.
No. A stripped deck cannot be left open and underlayment cannot be laid onto a wet surface. A forecast of rain stops the job, which is why a reroof can pause mid-week.
