The roof is the most important component of your commercial building. As such, it is also an expensive part to replace. After being worn down by the elements day after day, your roof will eventually need more than regular inspection. When getting a quote about a roof replacement, you will undoubtedly wonder about the price and whether it will fit into your budget. Your contractor will need to evaluate several factors before determining your exact total.
How Much Does It Cost to Replace a Commercial Roof?
Unfortunately, there is no clear-cut formula to calculate the cost of your roof replacement. Your quote will be determined by several different factors. Depending on the type of materials used on your roof, you can pay anywhere between $3 (single-ply flat roof) and $20 (tile roof) per square foot. Each type of material has its own average cost as all materials come in different sizes and types. However, other factors such as warranties and accessibility can also affect the cost.
Factors that Affect Commercial Roof Replacement Cost
A contractor can’t determine your quote by simply glancing at your roof. Several elements come into play when calculating the total. Here are the most common factors that influence the cost:
1. Type of Roof
First and foremost, your contractor will need to know what kind of roof materials to order as this will be the bulk of the cost. Flat and sloped roofs require different materials. Flat roofs typically are made of single-ply or built-up bituminous materials, and these can often be cheaper than sloped roof options. Sloped roofs have several options, including shingles, tiles, and metal.
2. Roof Accessibility
Depending on how easily accessible your roof is, your contractor may require extra equipment, which will boost the cost. The taller the building, the more likely your contractor will need a crane to transport materials. Further, sloped roofs are not always safe to stand on, requiring a man lift. If the roof construction will hinder normal business hours, then the adjusted work hours will entail additional costs.
3. Current Roof Condition
The state of your roof before construction can make or break your quote. In some cases, your roof might need a superficial face lift, but if the condition is too poor due to water and other types of damage in the insulation and substrate materials, then this will hike up the bill. The more damage to these materials, the more your contractors will have to strip from the roof, which adds labor and cost.
4. Local Code Requirements
Local codes can also affect your bill by requiring contractors to build roofs to a certain standard. These codes can mandate your use of fasteners in locations with extreme weather conditions, and they can limit your material options if your area requires a specific slope or aesthetic to your building.
After your roof has been replaced, you’ll have several warranty options, each varying in price. You’ll want to consider how cost-effective the roof warranty would actually be in the case that your roof sustains significant damage.
Once your new roofing system is in place, your contractor should review with you the best maintenance plan for your building. Not quite a warranty, but a way to help reduce future costs related to your roof. By getting your roof inspected regularly (at least twice a year), your contractor can catch minor damage before it worsens beyond repair. This will extend your roof’s life so a replacement roof is not necessary for some time. After your roof replacement, you can consider signing up for a maintenance contract. While it might be another addition to your bill, in the long run it could save you money.
Flat Roof Replacement Cost and Options
Flat roofs are much simpler to maintain than sloped roofs due to their easy accessibility (the flat surface makes them easy to walk on). However, they do not have as long a lifetime as sloped roofs. Flat roofs have a life of approximately 15 years as opposed to a sloped roof’s 20- to 30-year lifespan.

When it comes time to replace your flat roof, you can expect to pay roughly $5,000 based on the national average. At the highest, your bill might reach around $12,000. If these prices are way out of your budget, be diligent with regular maintenance to reduce the chance of a full replacement.
