How Long Does it Take to Replace a Roof?


One of the most common questions people have when their roof is being replaced is how long it will take? Having your roof replaced is a noisy process and home owners are happy to get it done as soon as possible.

For residential homes, roof replacements will usually take two days. The first day is to remove the existing roof from the building. The second day is to install the roof. Depending on the size of the roof a day or two longer may be necessary. If you are reroofing or roofing over your existing roof then you can subtract a day. If some of the plywood on the roof needs replaced additional time may be required.

Commercial roofs can take a few weeks to finish depending on the scope of the project. Some commercial roofs can be installed faster than others. For instance, cold sealed single ply roofs can be installed very fast and installation is generally quiet and noxious fume free.

When you call a roofer after it rains their schedule fills up fast. They may not be able to start your roof for a few weeks. This is true regardless of the size of the company.

Obviously, if there’s additional rain forecasted for the next few weeks this will delay your roof replacement. Roofs cannot normally be replaced during winter.

In general, it will take around a week to get three quotes from different roofers. Then it will take a few days to review their quotes and pick a company. After you sign the paper work, you can expect another few days until the roofer is ready to work on the roof.

Knowing which materials you want to use on your roof will increase the speed of the process. You are usually responsible for picking the roofing material you will use so you can get a head start easily.

A simple roof repair can be done in as little as two hours as long as additional work is not required. Some types of roofing take longer than others. For instance, tile roofs take longer than shingle roofs.

After installation your roof will need to be inspected. Depending on your municipality this could take anywhere from a few days to a few weeks.

Overall it will take at least a week or two to replace your roof. While this may seem like a long time, your roof will last for decades and will stop being something you will have to think about.

One thought on “How Long Does it Take to Replace a Roof?

  1. It is great to know that roof replacements only take about two days! I would have thought that it would take much longer than that. That is great to know so that I don’t have to plan on the company being at my home for a full week or more. It would still probably be good to plan for a couple extra day, just in case anything happens.
