A new roof is a big investment. It’s also a busy day at home: crews, trucks, tools, and plenty of noise overhead. Knowing what happens next can make the process feel much more manageable.

Here’s a realistic, hour-by-hour look at a typical asphalt-shingle replacement in Marietta. Every home is different, so the schedule can shift with roof size, roof complexity, weather, and the condition of the roof deck. For many single-family homes, the installation can be completed in one day, weather permitting.

Before the crew arrives: A few easy ways to prepare

A little preparation helps protect your belongings and keeps the work area clear.

• Move cars out of the driveway and away from the home if possible.
• Bring in or secure patio furniture, potted plants, and other loose outdoor items.
• Keep pets inside or arrange a quieter place for them during the noisiest parts of the job.
• Let children know that the work will be loud, and keep them away from the work zone.
• Cover or move items stored in the attic. Dust and small debris can fall through gaps during tear-off.
• Close windows and, if practical, keep them closed during the work.

Your project lead should also explain where the crew will stage materials and how they’ll protect the areas around your home.

6:00–8:00 a.m.: Arrival, staging, and property protection

The crew arrives, checks the plan, and sets up the work area. Depending on the property, that may include placing a dumpster or debris trailer and arranging the delivery of shingles and other materials.

Before work begins, the crew should take steps to protect the home and its surroundings. Tarps and other protective coverings may be placed over landscaping, walkways, decks, and areas near the air-conditioning unit. The crew will also set up ladders and safety equipment.

This is a good time to confirm where vehicles should be parked, where the crew will access the roof, and who to contact if you have questions during the day.

8:00–10:30 a.m.: Removing the old shingles

Next comes tear-off. The crew removes the existing shingles and underlayment, along with roofing components that are being replaced. Debris is gathered and moved into the designated disposal area.

This is usually the loudest part of the day. Expect hammering, footsteps overhead, and the sound of roofing material being moved. Crews typically work in sections so they can keep the project organized and manage exposed areas as they go.

If the roof has multiple layers or a complex layout, removal may take longer than expected. Your project lead can let you know if the pace changes.

10:30 a.m.–12:00 p.m.: Inspecting the roof deck

With the old roofing removed, the crew can inspect the wood sheathing beneath it. This is a crucial step. Soft, damaged, or weakened decking needs attention before new roofing goes on.

The crew checks for signs of water damage, rot, swelling, loose boards, and other issues, especially around valleys, chimneys, and roof penetrations. If repairs are needed, the project lead should explain what was found, show you photos when possible, and review any added work before proceeding.

At New Image Roofs, we believe an inspection should be honest and clear. We don’t use hidden damage as an excuse for pressure tactics or unnecessary work. If the deck needs repairs, you should understand why and what the repair involves.

12:00–1:00 p.m.: Preparing the roof for the new system

Once the deck is sound, the crew prepares the surface for the new roof. This may include installing drip edge, underlayment, and leak-barrier materials in areas where added protection is appropriate for the roof’s design and the project specifications.

These layers may not be visible once the shingles are installed, but they help direct water away from vulnerable areas and support the performance of the complete roofing system. Flashing and other details around walls, chimneys, valleys, and roof penetrations also need careful attention.

Georgia’s heat, humidity, heavy rain, storms, and occasional hail make sound installation details especially important. The right materials and methods depend on your roof and the agreed project scope, not a one-size-fits-all approach.

1:00–4:30 p.m.: Installing the new shingles

Once the roof is prepared, the crew begins installing the new shingles, usually starting at the lower edge and working up each section. You’ll see the finished roof take shape as the work moves across the home.

Many homeowners choose a premium architectural shingle such as Owens Corning Duration or a comparable product. As an Owens Corning Preferred Contractor, New Image Roofs follows high standards for workmanship and professionalism. Your proposal should identify the selected materials so you know what is going on your home.

The crew also works on the details that help the roof shed water: flashing around chimneys and walls, pipe boots, valleys, and other transitions. Those details deserve as much attention as the visible shingles.

4:30–5:30 p.m.: Finishing vents, ridges, and roof details

As shingle installation wraps up, the crew completes ridge caps and any specified ventilation work. They check flashing, roof edges, and penetrations, and make sure the finished sections look consistent.

Not every project follows this exact timeline. A large roof, complicated rooflines, extra decking repairs, or a weather delay can extend the work. A responsible contractor will prioritize safe, careful installation over finishing by a particular hour.

5:30–6:30 p.m.: Cleanup and a final walkthrough

Cleanup is part of the job, not an afterthought. The crew gathers leftover materials, removes protective coverings, clears debris from walkways, and checks the yard and driveway for roofing nails. A magnetic sweep helps collect stray nails, though it’s sensible to keep an eye out for debris after the crew leaves.

Before the team departs, ask your project lead to walk the property with you. Review the work from the ground, discuss any questions, and ask for photos of areas you can’t see. Confirm what happens next with project documentation, warranty information, and any required permit or inspection steps.

New Image Roofs treats every home like our own. That means taking care with the property, communicating throughout the work, and leaving the site as orderly as possible.

When will the roof be finished?

For many straightforward single-family homes, the roof replacement itself can be completed in one day, weather permitting. Larger or more complex roofs, hidden deck repairs, or changing weather can extend the schedule. Rain, high winds, and unsafe conditions may require a pause.

Your contractor should give you a realistic estimate for your home and keep you informed if conditions change. The goal is not simply to finish quickly. It’s to install the roof carefully and protect your home throughout the process.

If you’re researching roof replacement in Dallas, GA, or comparing roofing contractors in Marietta, GA and roofing companies in Cobb County, GA, ask each company how it handles decking repairs, cleanup, material details, and communication on installation day.

What to expect after installation

It’s normal to notice a few small pieces of debris after a busy roofing project, even after cleanup. If you spot anything concerning, contact your contractor. You may also hear a little settling or notice that the property looks different as materials and equipment are removed.

Keep your project paperwork and warranty information in a safe place. New Image Roofs provides industry-leading warranties, with coverage depending on the selected materials and project. Our team can explain the details so you know what applies to your roof.

Frequently asked questions

Do I need to leave home during the replacement?

Usually not. You can generally stay home, but expect significant noise and activity outside. If you work from home, have a noise-sensitive pet, or have a young child who naps during the day, planning an alternate space can help.

Will the crew protect my air-conditioning unit and landscaping?

Your project lead should explain how the crew will protect vulnerable areas before work begins. Let the team know about delicate plantings or other specific concerns during the pre-work walkthrough.

What if the crew finds damaged decking?

The project lead should show you what they found and explain the recommended repair before moving ahead with additional work. Damage concealed beneath old shingles can’t always be confirmed during the initial inspection, which is why clear communication matters.

Is a one-day replacement guaranteed?

No. One day is a common goal for many single-family homes, but the roof’s size and design, unexpected repairs, and weather all affect the schedule. A quality installation should never be rushed to meet an unrealistic deadline.
