You signed the contract for a roof replacement process, the dumpster is on the driveway, and you suddenly have no idea what happens next. The crew shows up before sunrise, the dog is panicking, and the foreman is asking about driveway access and the breaker panel.
A typical roof replacement process takes two to four days for an average single-family home, from tear-off to final walkthrough. Each day has a clear purpose, and knowing what is coming turns the project from a black box into a checklist you can follow along.
Week One: Estimates, Scopes, and the Contract
The roof replacement process really starts the week before the crew shows up. This is when you compare bids and lock in the details.
The first step is measurement and inspection. A good roofer walks the roof, takes photos, and measures every slope from the eaves to the ridge. They are looking at deck condition, flashing status, vent count, and any code-driven detail your jurisdiction cares about.
The second step is the written estimate. A clear bid names the shingle brand and product, the underlayment brand and type, the linear feet of ice and water shield at the eaves, the flashing scope, and the ventilation plan. For what those numbers mean and how to read them, our roof replacement cost guide has the line-by-line breakdown.
The third step is the contract and deposit. Most residential roofers take a deposit of 10 to 30 percent at signing, with the balance due at completion. Never pay the full amount in cash, and never let a deposit exceed what the supplier costs them in materials.
The fourth step is the permit. Most jurisdictions require one for a full tear-off under section R105 of the IRC. The roofer usually pulls it, but the homeowner is on the hook for the inspection. Our roof replacement permit and code requirements page covers what your local office actually asks for.
The fifth step is the material drop. A few days before the job, the supplier delivers the shingles, underlayment, flashing, and vents to the driveway. Photograph the pallet shrink wrap. If you ever file a warranty claim, the date on the wrap is part of the proof.
Day One: Tear-Off, Inspection, and Dry-In
The first day of the roof replacement process is the loudest and the most important. Get the sequence right and everything after is straightforward.
- Move vehicles, patio furniture, and the trash bins away from the house before the crew arrives at 7am.
- The crew protects the site: tarps over shrubs, plywood against siding, magnets placed for the nail sweep at the end.
- Tear-off happens in sections so a surprise thunderstorm does not soak the deck.
- The foreman walks the deck, marks bad panels with chalk, and flags anything else worth your attention.
- Decking repairs get written up and priced before any new underlayment goes down.
- Synthetic underlayment goes on bottom-up, with ice and water shield at the eaves first, then valleys.
- Drip edge is nailed along the eaves before the underlayment laps over it.
- By end of day, the roof is “dried in,” meaning it is fully wrapped and safe overnight.

Day Two: Flashing, Shingles, and the Field
Day two of the roof replacement process is where the visible work happens. The dry-in becomes a finished surface.
The first task is flashing. New flashing at all penetrations, valleys, and wall transitions goes on before any shingles. This is one of the most overlooked places in a bid and one of the most common sources of leaks when it is done wrong.
The second task is the starter strip. The first course along the eaves is a glue-lined starter strip that seals the shingles against wind lift. Skipping this is a classic shortcut and a common failure point.
The third task is the shingle field. Each course overlaps the one below it, with nails landing in the nailing strip, not above it. Most manufacturers now require six nails per shingle for high-wind warranty coverage.
The fourth task is the valley detail. There are two common styles: woven valleys where shingles run across the valley, and open valleys where a piece of metal valley flashing shows. Open valleys shed ice better in cold climates.
The fifth task is the ventilation. Ridge vent runs along the peak, box vents go in the upper third of the roof, and any powered fan gets wired in. Our roof ventilation types guide covers which is right for your attic shape.
Day Three: Ridge, Cap, and the Cleanup
Day three wraps the visible work and starts the cleanup. Most average homes are buttoned up by end of day three.
The first task is the hip and ridge cap. These are special shingles that cover the peak of the roof and the hip lines. They are installed with longer nails than the field because they see more wind.
The second task is counter-flashing at the chimney. If your home has a brick chimney, the metal counter-flashing gets tucked into a reglet cut into the mortar. This is a small detail with a big impact on leak prevention.
The third task is the final inspection of penetrations. Every plumbing vent boot, every bathroom vent cap, and every gooseneck gets checked. This is the day to walk the roof with the foreman if you can do so safely.
The fourth task is the magnetic sweep of the yard. The crew runs a rolling magnet around the house to pick up dropped nails. Most reputable roofers do this twice: once before they leave, once the next morning.
The fifth task is the dumpster pickup. The roll-off container leaves the same day or the next morning. By end of day three, the driveway is empty and the project is structurally complete.
Day Four and Beyond: Walkthrough, Payment, and Paperwork
The final part of the roof replacement process is the boring part that protects you for the next twenty-five years. Do not skip it.
The first task is the final walkthrough. Walk the roof with the foreman if possible, or at least walk the perimeter. Look for missing shingles, exposed nail heads, flashing gaps, and any debris left in the gutters.
The second task is the payment and lien waiver. Pay the final invoice only after the work is complete and the site is clean. Ask for a lien waiver from the roofer and from the material supplier.
The third task is the warranty registration. Most shingle manufacturers require registration within 60 days of install. Without it, the warranty defaults to the basic coverage, which can be half the duration of the registered version.
The fourth task is the inspection. Most jurisdictions require a final inspection by the building department. The roofer usually attends, but you should know when it is scheduled and confirm it passed.
The fifth task is the file the paperwork. Save the contract, the invoice, the lien waivers, the warranty registration, and the inspection sign-off in one place. If you sell the house, this folder is the difference between a smooth closing and a buyer asking for credits.
For the project before the noise starts, our roof replacement pillar covers the decisions that lead up to the contract. If the timing on payment is tight, our financing a new roof options page breaks down home equity, contractor programs, and FHA Title I loans side by side.
For the choice of contractor in the first place, our how to choose a roofing contractor checklist is built for the moment you are staring at three estimates and trying to pick one.
If you are still unsure whether you need a full replacement, our roof replacement vs repair page has the decision framework to help you tell.
For the symptom side and whether the project is even needed yet, our signs you need a new roof guide walks through the twelve clues to check first.
And if the project is storm-driven, our storm damage roof insurance claim guide covers the documentation that adjusters actually look for during their visit.
A good roof replacement process is mostly predictable. The foreman knows the order, the crew knows the rhythm, and you know what is coming each day. The trick is recognizing that the steps look small until you stack them into a finished roof.
