What is the cost of commercial roof replacement?

If you are a business owner, you know that replacing your roof is costly. Commercial roof replacement can be expensive, and it’s essential to factor in the associated costs before deciding. In this blog post, we will look at some factors that affect the cost of commercial roof replacement and how to get the best deal on your new roof.

Cost of a Commercial Roof Replacement Based on Their Types

When it comes to commercial roof replacement, the costs can vary greatly depending on the type of roof you are replacing. Whether you have a flat roof, a pitched roof, a rubber roof, or a metal roof, there is no one-size-fits-all approach—each type of material requires its installation process and may involve additional labour costs. With that in mind, let’s take a closer look at what goes into each type of commercial roof replacement cost so you can budget accordingly for your next project:

Single-Ply Membrane Roofing

Single-ply membrane roofs are among the most popular commercial roofing types on the market today, and they come in several different forms: EPDM rubber membrane, PVC membrane, and TPO membrane. These roofs can cost anywhere from $2.50 to $5 per square foot installed, depending on the type of material you choose.

Metal Roofing

Metal roofs are known for their durability and energy efficiency, but they can be expensive to install. Steel is the most common metal used for commercial roofs because it is lightweight and durable. Average installation costs for steel range from $4 to $9 per square foot, depending on the specific type of metal you choose.

Built-Up Roofing

Built-up roofs (BUR) are one of the oldest types of roofing systems, and they consist of layers of asphalt and tar paper. BUR membranes can be reinforced with fibreglass or polyester mats for extra strength and protection. Installing a built-up roof costs around $3 to $6 per square foot.

Modified Bitumen Roofing

Modified bitumen roofing is a hybrid system that combines asphalt, rubber, and plastic to create a durable membrane. It’s similar to BUR but is more flexible and has more waterproofing capabilities. A modified bitumen roof costs between $6 and $10 per square foot.

Slate Roofing

Slate roofs are made from natural slate and provide a classic, elegant look. They’re also highly durable and can last up to 100 years if installed correctly. Slate roofs are expensive, costing around $20 to $30 per square foot.

Foam Roofing

Foam roofing is a spray-on roofing solution. It’s lightweight and easy to install but also durable and energy-efficient. Foam roofing can last up to 50 years and costs around $4-$6 per square foot.

Wood Shake Roofing

Wood shake roofs provide a rustic, natural look that many homeowners find appealing. Wood shakes are also very durable and can last up to 50 years if properly maintained. The cost of wood shake roofing averages around $7-$14 per square foot.

Solar Roofing

Solar roofing is becoming increasingly popular as a way to save money on energy costs. Solar roofs are made up of small photovoltaic cells that collect sunlight and convert it into electricity. Solar roofing can cost anywhere from $15-$30 per square foot, depending on your type of system.

Factors That Affect the Cost of Commercial Roof Replacement

When it comes to commercial roof replacement, myriad factors will impact the overall cost of a new installation. Here are some common factors that need to be taken into consideration when estimating the overall price:

  • The age and condition of the existing roof
  • The size of the roof
  • The type of materials and products used
  • Labor costs
  • Location-specific weather conditions and other environmental factors
  • The overall complexity of the project
  • If any additional components are needed to complete the installation, such as ventilation systems or skylights.
  • The slope of the roof
  • Accessibility (whether or not heavy equipment is required)
  • Any pertinent local building codes.


Depending on the size and type of commercial roof, the replacement cost can vary widely. However, it is essential to factor in the initial price tag and the long-term costs of maintaining a commercial roof.
