What Happens on Roof Replacement Day? A Real Charlotte Job, Step by Step

Finished Owens Corning Duration roof in Williamsburg Gray on a Charlotte NC home and garage

A roof replacement is a big project, but for most Charlotte homes it's finished in one to two days. Knowing what happens, and in what order, makes the whole thing a lot less stressful.

Below we walk through a real replacement our crew completed on Monroe Rd in Charlotte: Owens Corning Duration shingles in Williamsburg Gray, from tear-off to final cleanup.

Before Replacement Day

Most of the decisions happen before the crew shows up:

  • Inspection and measurements. We get on the roof, measure every slope and check the decking, flashing and ventilation so the estimate reflects your actual roof.
  • Shingle and color choice. We install Owens Corning, GAF and CertainTeed. Not sure which? See What Shingles Are Best for a Charlotte Roof Replacement? and Oakridge vs. Duration.
  • Scheduling and delivery. Materials are usually dropped off shortly before the job, often in the driveway.

How to get your home ready

  • Move cars out of the garage and driveway the night before.
  • Take pictures and mirrors off walls. Hammering can shake them loose.
  • Cover items stored in the attic. Some dust will fall through.
  • Keep pets and kids inside or away from the work area.
  • Move patio furniture, grills and potted plants away from the house.

Step 1: Protect the Property and Tear Off the Old Roof

The crew covers landscaping and sets up for debris, then strips the old shingles, underlayment and worn flashing all the way down to the wooden deck.

Step 2: Inspect and Repair the Decking

With the old roof off, we can finally see the plywood underneath. Any soft, rotted or delaminated boards get replaced so the new shingles have a solid surface to nail into. Your estimate should spell out how decking replacement is priced, so there are no surprises.

Step 3: Drip Edge, Leak Barrier and Underlayment

This is the layer you never see, and it's what keeps water out when a shingle fails:

  • Drip edge along the eaves and rakes guides water into the gutters and protects the deck edges. (More on drip edge and flashing.)
  • Ice and water shield goes in the valleys and around penetrations, where leaks usually start.
  • Synthetic underlayment covers the rest of the deck as a second line of defense.

Step 4: Shingles

Starter strips go along the edges first so the first row seals properly. Then the shingles go on row by row, nailed in the manufacturer's nailing zone. Correct nailing is what keeps shingles on in a Charlotte thunderstorm.

Step 5: Flashing, Pipe Boots and Vents

Chimneys, walls, skylights, plumbing pipes and vents are where most roofs leak. New flashing and new pipe boots go in with the new roof. Reusing old, cracked boots is a common shortcut that causes leaks a few years later. (See common roof leaks and pipe boot repair.)

Step 6: Ridge Vent and Ridge Cap

The peak of the roof gets a ridge vent to let hot, damp air out of the attic, then ridge cap shingles over the top. Good ventilation helps your new roof last its full life and can make upstairs rooms more comfortable in summer.

Step 7: Cleanup and Final Walkthrough

The crew clears debris from the roof, gutters and yard and runs a magnetic sweeper over the lawn and driveway to pick up nails. Then we walk the job with you and share photos of the finished roof.

How Long Does It Take?

Most single-family roofs are done in one to two days. Larger or steeper roofs, homes with a lot of rotted decking, or rain delays can add time. We'll give you a realistic timeline up front.

Frequently Asked Questions

Do I need to be home during the roof replacement?

No, as long as we can reach the work area and an outdoor outlet. Most homeowners like to be around at the start and for the final walkthrough.

Is a roof replacement loud?

Yes, especially during tear-off and nailing. If you work from home, plan to work from somewhere else for the day.

What happens if it rains?

We watch the forecast and only open as much roof as we can dry-in that day. If weather moves in, the exposed areas get covered.

How much does a roof replacement cost in Charlotte?

It depends on size, pitch, material and decking condition. See our 2026 Charlotte roof cost guide or roof replacement in Charlotte.
