How Long Does It Take to Replace A Roof

When a roof is due for an upgrade or a repair, there is one question that often comes up. How long does it take to replace a roof?  Many factors go into the time that it takes to replace a roof and it is always a good idea to consider everything involved before starting your project.

The duration of a roof replacement depends primarily on the size of the roof, the difficulty of the replacement, and the complexity of the job. Roof replacements can take anywhere from one day for smaller roofs and up to 5 days for larger projects.

Factors Affecting the Duration of a Roof Replacement

As there are many factors that go into a roof replacement, it is a good idea to look at each on its own.


One important factor is the material type that the roof is made from. Whether the roof is made from natural slate, asphalt shingles, wood shakes, concrete tile, or any of the other common material types, each will have a different scope of time for the installation.

The materials that take the least amount of time are asphalt shingles and rolled roofing. For a roof of 50 sq ft and at least three people working on the project, you could expect anywhere from 1-9 days for the entire replacement to take.

Materials that take a bit more time are wood shakes, synthetic slate, and steel sheets. These materials generally take from 3-5 days from start to finish.

The materials that take the longest to install include natural slate and concrete tile. If you would like to go with these materials, expect a time window ranging from 7-9 days.


Weather is another key factor that should be considered. Not only can roofs only be replaced in good weather but that weather should last for the duration of the project. In short, that means that even if a roofing job is slated to last for as little as two days, the wait for optimal weather conditions could mean that the job will take longer than you might expect.

Certain materials ‘cure’ differently than others in certain temperatures, as well. For example, tar and some rolled roofing materials will set up better in warmer weather. If you live in a cold, humid climate, the same material could take longer.

Team Size

The size and quality of the roofing team that you hire will have a major impact on the amount of time that a roofing replacement can take. There are many roofers who work on their own or have small teams of just a handful of helpers to complete the job at hand.

Longer replacement time frames are also common for DIY’ers who choose to handle their roof replacement on their own.

On the other side of that coin, there are also major firms that send out entire teams to tackle jobs within a very short time window. These companies have all the materials, experience, and equipment necessary to cut down the required amount of time for a roof replacement.

Prep Work

Another important factor that should be considered when planning out the time required for a roof replacement is the prep work that you must do before applying the new materials.

Again, depending on the extent of any damage, what materials are used, and how many people are tasked with the job, removing the old roof can take at least a day.

If you only need to remove the superficial roofing materials, the time required will be much less. If there are pieces of the roof that need to be removed or replaced, such as rotten wood, the time required to remove and replace those parts could be longer.

Timing Your Roof Replacement

Replacing a roof is a big job and many people try to put it off for as long as possible. There are quite a few valid reasons for waiting. Replacing a roof can be costly, deciding on whether to patch or completely replace a roof can be a difficult decision, and trying to decide on a specific roof style can all make putting it off seem like a good plan.

There are, however, even more reasons for replacing a roof when a replacement is required. The big question is, then. How do you know when you should replace your roof? Here are a few fey points to consider.

Organic Materials

An often-overlooked problem that many roofs face is the buildup and growth of organic materials on the roof and roofing materials.

Moss, grasses, and many other types of plants can find homes on a roof for different reasons. When this happens, the roots and moisture buildup can lead to rot as well as dislodging tiles and other roofing materials. Having organic materials growing on a roof can also be indicative of other, more serious problems.


One thing that should never be ignored is roof damage, even if that damage seems insignificant. Any cracks, holes, or splits in the roofing material must be repaired right away.

Depending on the extent of the damage, you may not need to replace the entire roof but keep in mind that roofs are systems and all of the various parts of that system work together. It is often the case that when you repair one part of a roof, other parts must also be upgraded or fixed.

Keep a close eye out for missing shingles, broken roof tiles, or any other forms of damage that your roof might be suffering from.

Wear and Tear

While it may not always seem like it, wear and tear can also lead to various problems. The types of problems that can come up from wear and tear include bad water runoff, clogged gutters, leaks, and many other issues.

Discoloration can be a telling sign that a roof is aging and should at least be checked periodically. This is especially true when it comes to asphalt tiles. Asphalt tiles take on a different appearance when the grit that is glued to the top of them begins to wear off. This grit helps protect the tiles from the sun and will become damaged very quickly without that protection.

Structural Issues

Sometimes, the problems that face roofs go deeper than the top layers. And, it is in these cases when the entire roof needs to be replaced. If you notice any sagging in the roof, the structure that the roofing materials are applied to will need to be rebuilt.

Other problems that can be caused by structural issues are gaps and holes in the roof. One way to spot issues like this is to go into the attic during the day and look for any signs of light coming through. If there is any extensive damage from water or falling branches, it will usually be evident through observation.

How much should a DIY roof replacement cost?

There are several different factors that go into the cost of a roof replacement. As a result, the cost of one roof replacement can be considerably different than the next, even when those roofs are the same size.

In nearly every case, replacing your roof on your own will reduce the overall cost of replacing a roof by approximately half. For an average-sized roof, expect to pay anywhere from $2000 to $8000, depending on the materials that you choose.

Where can I find the money that I need to replace my roof?

For many, the need to replace a roof can come as a surprise.  Damage can come from something (like a branch) falling on top of your roof, or when water has been eating away at the sublayers of the roof for a long time. In almost every case, many homeowners are not financially prepared when the need to replace the roof arises.

Fortunately, there are a few avenues that you can explore to find the money that you need to complete the roof replacement. First, check to see whether your insurance company can help you cover the cost. If not, you might want to consider obtaining a personal loan or possibly even a refinance on a car or home.
