A full tear-off and reroof sounds daunting, and it is a big project, but it follows a clear, orderly sequence. Knowing the steps takes the mystery out of it and helps you understand what you are paying for and why the schedule and the noise fall where they do. Here is what actually happens, from the crew arriving to the final cleanup.
The day starts with setup. The crew stages materials, positions a dumpster, usually in the driveway, and protects the areas around the house, since a tear-off drops a lot of debris. Landscaping, walls, and windows near the roofline get covered. This groundwork is what keeps the mess contained and the job efficient.
Next comes the tear-off itself, the loudest and most visible stage. The old roofing is pried off and dropped into the dumpster, right down to the wood deck. On a tile roof, the tile is removed, and if it is being reused, it is set aside carefully. This is the stage that generates the scraping and thudding, covered on our page on whether a replacement is noisy.
With the old roof off, the wood deck is exposed and inspected. Any soft, rotted, or damaged decking is replaced before anything new goes on, since a new roof over bad wood is a wasted roof. This is the step that can add cost, because deck damage often only shows once the roof is open, covered on our page on the real cost drivers.
| Stage | What happens |
|---|---|
| Setup and protection | Stage materials, cover the surroundings |
| Tear-off | Strip the old roof to the deck |
| Deck repair | Replace any rotted wood |
| Underlayment | Lay the waterproof barrier |
| Flashing and new surface | Seal joints, install tile or shingle |
| Cleanup and inspection | Magnetic sweep, final check |
Now the roof is rebuilt from the deck up. The underlayment, the real waterproof layer, goes down first, then new flashing is installed at the chimney, walls, valleys, and penetrations. These are the parts you never see but that keep the roof dry, and they are where a quality job separates itself from a cheap one.
Finally the new tile, shingle, or membrane goes on, fastened and detailed. When the roof is complete, the crew cleans up thoroughly, including a magnetic sweep of the yard and driveway to pick up stray nails, and does a final inspection. The permit inspection also happens as part of the job, covered on our page on roof permits. The whole sequence runs one to a few days depending on size and material, covered on our page on how long it takes.
