Roof Replacement: What to Expect, Step by Step

Step 1: Inspection and quotes

A roofer inspects the roof, the attic, and the ventilation, then gives you a written quote. Get at least three itemized quotes that cover the same scope: tear-off, underlayment, flashing, ventilation, decking allowance, cleanup, and warranties.

Step 2: Choose materials

Asphalt shingles are the most common choice. Metal, tile, and other materials cost more but can last longer. You'll also choose colors and, in some cases, upgraded underlayment or ice-and-water shield for cold climates.

Step 3: Permits and scheduling

Most areas require a permit for a full roof replacement, and your contractor typically pulls it. Materials are delivered a day or two before work starts. Roofers watch the forecast closely, so be ready for date changes due to rain or wind.

Step 4: Prepare your home

• Move cars out of the driveway and garage.
• Take down wall hangings on top-floor walls, since hammering causes vibration.
• Cover belongings in the attic to catch dust and debris.
• Keep kids and pets away from the work area.
• Mark sprinkler heads and protect delicate plants.

Step 5: Replacement day

• Tear-off: old roofing is removed down to the decking.
• Decking inspection: rotted or damaged boards are replaced.
• Underlayment and ice-and-water shield are installed.
• New flashing, drip edge, and vents go in.
• Shingles or panels are installed, then ridge caps.

Step 6: Cleanup and final inspection

The crew should haul away all debris and run a magnetic sweeper over your yard and driveway to pick up stray nails. A final inspection, by the contractor and often the local building department, confirms the work meets code. Keep your contract, permit, invoices, and manufacturer and workmanship warranties in one place.
