How Long Does It Take to Replace a Roof?

Your roof shields your house from the elements, so replacing it when necessary is crucial. You may assume replacing your roof will be a drawn-out process, but it doesn’t need to take too long—it could take as little as one day. But the specific timeline of a roof replacement depends on unique circumstances.

Let's dive into the various factors that could impact your roof replacement timeline, so you can plan ahead and put your mind at ease.

How Long It Takes to Replace a Roof

The process for replacing your roof will depend on the specific roofing service you use and your contractor. Generally, replacing a roof will be a similar process for every home. You'll likely have an initial meeting with your contractor, who will take measurements and inspect areas of your home and roof.

You may have another meeting to finalize the roof design and specific roof materials. Finally, you'll wrap up a contract. After you've both looked it over and agreed, you'll sign it, and the project will begin. Depending on your roofing material, it takes between one and 12 days to replace a roof. Standard asphalt roofs usually only take one to three days to replace.

Factors That Impact a Roof Replacement Timeline

Several factors will influence the timeline of your roof replacement. 

1. Roof Size and Complexity

A common rule of thumb is that the larger your home, the longer it takes to replace its roof. However, this may not always prove true, particularly if you have a roof with an extensive surface area. It can take as little as a day with small homes, while larger homes often take several days.

The complexity of your roof’s design also contributes to the installation timeline. Features like chimneys and skylights, multiple stories, and particularly steep pitches all add to the complexity of a roof installation project.

2. Roof Material

You can choose from a few different roofing materials. The type you pick will impact how long it takes to replace your roof.

The most common roofing materials are asphalt, wood, slate, concrete, metal, and tile. Here's how long it generally takes to replace roofing based on materials:

3. Replacement Method 

Your roof replacement timeline will also depend on which method your contractor uses. Two common methods are tear off and overlay. The roofing materials typically influence which way is best.

• Tear-off method involves—you guessed it—tearing off and replacing the damaged areas on your roof. 

• Overlaying is when your contractor installs new shingles directly on top of damaged areas. This method of roof replacement costs less and is quicker than the tear-off method. The downside of the overlay process is that it may cover up problems instead of fixing them. It could also void your manufacturer warranty.

4. Roof Accessibility 

Roof accessibility—which is the ability of a contractor to access your roof—will be a significant factor in how long it takes to replace your roof. For instance, if you have lots of landscaping, bushes, or fences around your house, your roof is harder to access than a house without it. Additionally, it may be harder to access your roof if you live on a street with densely packed houses.

5. Weather

You should plan a roof replacement project around the weather—avoid doing it when you expect rain, snow, or extremely hot or cold temperatures. Your contractor will likely push back the project if the day arrives and it's, for instance, hailing. Rain will also pause the job. Homes with shingle roofs are particularly susceptible to extreme weather.

DIY vs. Hiring a Pro to Install a Roof

Going the DIY route can save you money on labor fees. However, doing it yourself will impact your timeline because it's unlikely the average homeowner can complete the installation as quickly and efficiently as a professional roofer.

But more importantly, replacing a roof yourself poses a risk for serious injury since you could slip and fall while working on the roof or climbing a ladder. The project gets riskier if you're handling heavy equipment. That's why it's better to hire a professional roofer. to do the job for you. A roofer will also know how to navigate the permitting requirements for a roof project.
