Anyone who has dealt with the replacement of a roof before knows that the costs associated with it can vary greatly. This is especially true when it comes to commercial roofing, as commercial roofing material can carry different costs depending on the context. In this article, we will explore the factors that affect commercial roofing costs so you know what you expect before you embark on a new project.

What is the Average Cost of Replacing a Commercial Roof?

It is difficult to give a simple answer to what the cost of replacing a commercial roof should be. The best way to set clear expectations for yourself or for your company is to request a quote based on your particular situation.

The reason behind this is because factors such as the size of your roof and the materials used on your roof will greatly affect your quote — we will go into this in more detail in a bit. In short, you can expect to pay as little as $3 per square foot to as much as $20+ per square foot to replace your commercial roof.

Factors That Will Affect the Cost of Replacing Your Commercial Roof

When you are dealing with a commercial roof replacement, it’s important to know what exactly you are getting yourself into. Here is an overview of the things that may affect your commercial roof replacement costs.

Your Roof’s Condition

This is the most obvious factor, so let’s start with it. The better condition a roof is in, the more likely it is to cost less to repair. For example, if you are simply seeking repairs for cosmetic issues, this is likely to be a lot softer on your pocketbook than, say, the fixing of water damage or holes. While it may be tempting to skip out on small, cosmetic repairs, note that keeping on top of these can help you save yourself from major roof damage, and as a result can save you from more costly repairs down the road.

How Accessible Your Roof Is

If your roofer requires special equipment or effort to reach your commercial roof, it is likely that you will pay the price (quite literally). This could ring true for roofs that are at a sharp angle, or roofs that are particularly tall.

It is also true that it may cost you more to have your commercial roof worked on if you are requiring your contractors to do the work outside of regular business hours — some businesses will choose to do this so as to not disturb employees who work during the day.

The Type of Roof You Have

Do you have a flat roof or a sloped roof? Knowing the answer to this can help you determine just how expensive your roof replacement will be. While flat roofs can be rather inexpensive thanks to their low-cost materials, shingling a sloped roof can be a bit more complicated which can drive up costs.


The design of your roof will affect its costs, too. Obviously, basic and non-fuss designs will require the least amount of work, while more intricate designs like a gable will require a bit more time and energy (read: a bit more of a cost).

Local Permits and Standards

Commercial roof repairs may vary based on jurisdiction. The reason behind this is because some areas may have rules and regulations that commercial roofers must adhere to. For example, if you operate in an area that experiences extreme weather, you may be required by law to consider extra precautionary measures with the installation of your roof to ensure that it is strong enough to withstand the forces of nature.

Your Roof Maintenance Habits

Have you always kept up-to-date on all maintenance on your roof? Sometimes, if you have a lease on a building that had previous tenants, there is only so much control over this that you can have. However, once you have your commercial roof repaired, your contractor can point you in the direction of maintenance best-practices that can save you some money in the long run. This may include things like getting your roof inspected regularly, getting minor damage fixed as soon as possible, and looking into the possibility of getting a roof warranty.
