How Long Does a Roof Replacement Take?

Generally, a roof should be replaced about every twenty-five years. However, if your roof has endured harsh weather, you may need to replace it much sooner.

If you fall into these categories, you may be wondering, “How long does a roof replacement take?” We know it’s not ideal to have construction workers going to and from your property, banging on your roof, and disturbing your family. Read along to find out how quickly a roof replacement can be accomplished!

How Long Does a Roof Replacement Take?

Roof replacement time can vary based on several factors. Of those, the size of the roof and the types of shingles are two elements that have a big impact on replacing a roof.

While the tearing off of the old roof can be done relatively quickly, about a day, it could take longer to install depending on the chosen roofing materials. All of our estimates assume you are hiring a professional company that will send at least five employees to the job.

Roof Size

If the square footage of your roof falls below three thousand square feet and you have a simple material, we have good news for you! Your roof should be replaced within the day.

If you have more than three thousand square feet, it could take up to a week. This is also in part to the different levels that come along with a larger roof size. The steeper your roof or parts of your roof are the longer it will take.

Types of Commercial Roofing

There are several types of commercial roofing systems, each with its own benefits and drawbacks. The most common type of commercial roof is the flat roof, which is popular for its low cost and easy installation. However, flat roofs are more susceptible to leaks and ponding water, which can shorten their lifespan. These can take anywhere from a few days to a couple of weeks to replace.

The next most common type of commercial roof is the metal roof. Metal roofs are more durable than flat roofs and can last up to 50 years with proper maintenance. However, they are also more expensive to install and require more regular maintenance than other types of roofs. Replacing this type of roof usually takes up to three days.

The last type of commercial roof is the single-ply roof. Single-ply roofs are made from a single layer of material, typically rubber or plastic. They are very durable and can last up to 30 years with proper maintenance. However, they are also more expensive to install than other types of roofs and require more regular maintenance.

The last type of commercial roof we will discuss is the green roof. Green roofs are a newer type of roof that is becoming increasingly popular due to their many environmental benefits. Green roofs help to insulate the building, reduce stormwater runoff, and improve air quality. However, they are also more expensive than other types of roofs and require more specialized maintenance.

What Can Slow the Process Down?

The above estimates are what to expect in a perfect world. Unfortunately, we don’t live in a perfect world, and sometimes things happen that slow down the construction process. A few examples of this are as follows:

  • Weather
  • Season
  • Structural Damage


Roofers can’t work in storms, and you wouldn’t want them to either. The last thing you want is a half-exposed roof with a rain storm blowing through, as your roof is your only line of defense.


Similarly, they can’t work in low light. Seasons where the sun is setting earlier means they have less daylight to work within. Be aware of this when deciding when to replace your roof.

Structural Damage

Finding structural damage is rare unless you are in an old home, but this could result in extended replacement time. This is because supports might need to be completely replaced.

Final Thoughts

While you may initially want to choose a company with the fastest results, this isn’t the only motivating factor. Some companies will often tell you what you want to hear to get the work. Always choose quality over speed!
