Replacing Your Commercial Roof: How Much Will a Commercial Roof Replacement Cost Your Business?

If you own a commercial building, you know that protecting your roof means protecting your business. Just like your roof at home, your commercial roof also requires maintenance, and, eventually, replacement to ensure your building value remains intact. But how much does it cost? Well, just as your business is unique, your roof is too, and the cost to replace it depends on a number of variables. 

Commercial roofing design

The roofing system can be dramatically different for commercial and residential roofs. Commercial roofs typically are lower sloped or flat, and are usually much larger than residential homes, meaning a much larger roof design and different roofing needs

Factors of commercial roof replacement cost

Because commercial roofing systems are so complex, there are many factors that can impact the cost to replace your business’s roof. Some reports state that the average cost to replace your commercial roof can range from $4 a square foot all the way to $15 or more. With such a broad range, it’s important to understand why there is such a large range, and where your business fits into it. 

Types of Commercial Roofing System

There are two main types of commercial roofs; flat or sloped. The type of roof can impact how easy it is to access, and the material it’s made of. Sloped roofs provide a much larger variety in roofing materials over flat roofs. 

Commercial Roofing Materials

  • Single-ply roofs are seen on flat roofing systems, and are most cost effective and easiest to install. 
  • Built-up bituminous or modified bitumen roofs provide additional layers and protection for flat roofing systems over single-ply, but will increase the price of your replacement. 
  • Shingles are seen on sloped roofs, which can add aesthetic value to the visible roof. The price of replacement will depend on the type of shingle (asphalt shingles, wood, and slate are popular options for commercial roofs).
  • Tiles are another option for sloped roofs, and can last up to 50 years. However, this material is also typically the most expensive. 
  • Metal roofs, available in a variety of different kinds of metal, are a popular option for sloped commercial roofs. This option can appear in different styles or colors, but is often one of the most expensive types of roof. 

Damage to Roof

Depending on the roofing system underneath your roof, as well as insulation, there may be hidden costs to repair what is underneath your roof and protect your building from moisture. These costs can be difficult to predict and anticipate until you know what is underneath your existing roof, and can quickly add up if any hidden issues arise. 

Size of Roof

Of course, the larger your roof, the more expensive it will be to replace. However, the cost per square foot may go down depending on your material and roof style, offering savings for larger roofing systems. 

Roof Structures

The number of structures on your roof will impact the cost of installation, as installers have to work around them. This includes venting and drainage systems. 

Permits and Codes

If your roof requires special permits, this will add additional time for installation and cost to your estimate. Also keep in mind any local codes that your roof will need to adhere to.

Extra Considerations

Sometimes commercial roofs need upgrading to the slopes to drain, insulation, or parapet walls. All of these are additional costs that can be quoted by your roofing contractor and should be carefully considered as a roof, no matter the materials, cannot function properly without a whole system that functions together to protect your building.
