Commercial Roof Replacements: 6 Factors That Affect Their Cost
How To Estimate The Cost Of Your Arizona Commercial Roof
Commercial roofs last longer than their residential counterparts, but that doesn’t mean they won’t ever be replaced. These roofs are also pricier than residential ones, so you should be aware of the main factors that affect the replacement cost.
Understanding these factors can help you know how much to pay. Accordingly, a Phoenix roofing contractor listed below the top 6 factors to notice.
The Type Of Roof You Are Choosing
Commercial roofs have different designs and shapes, and each one was built according to the building’s needs. These roofs tend to be flatter than residential ones, even if they’re slightly sloped to avoid water.
The type of roof you choose affects replacement cost, so you must be smart about the design you prefer for the project.
This factor plays an essential role in the longevity of the roof and its overall health. Plus, it may affect the total cost of installation too.
There are many commercial roofing materials to choose from, but consider the following before choosing one:
- The size of the building
- The weather in the area
- Underlying roof composition
- Structures you will place on the rooftop
- Durability and energy savings.
The Roof Material
In addition to the type of roof, you should notice its material because it will also affect the replacement cost.
These are the most popular commercial roofing materials for both new roof and re-roof work:
- Modified Bitumen (Mod Bit) and Built-Up Roofing (BUR). Both materials can last 50 years or more, but they require hard-working installation, so the Paradise Valley roofing company can charge you a pricey bill for it.
- Ethylene Propylene Diene Methylene (EPDM). It is the least expensive material and it helps lower energy costs if applied in white. However, it is relatively fragile and lasts only 20 years.
- Thermoplastic Polyolefin (TPO). It reflects heat better than EPDM. Plus, it requires low maintenance. The only disadvantage is its shorter lifespan.
- Polyvinyl Chloride (PVC). It is one of the strongest and most durable roof materials, but it requires complete removal of the old roof when doing a re-roofing project (in other words, it is also expensive).
What’s Underneath Your Roof (Layer Cake)
Many property owners do not see how much their commercial roof simulates a layer of cake. Under the roofing material is a combination of many components that make up the roofing system. You will see things like:
- Shaped and sloped insulation
- Decking components (concrete, wood, metal, etc.)
- Felts (depending on the type of roof)
- Other substrate materials
As you can guess, these things add time and cost to the whole project, but they are essential to make it successful. The best you can do is to take note of each one so you don’t get a surprise when paying for the replacement.

Understanding Wind Loads and Fastenings
The environment and microclimate of your building’s location affect replacement costs. These factors determine the building codes in each state, including Arizona, so you must take note of that before replacing the roof.
Building codes and weather will determine the wind loads and fasteners your commercial replacement roof must handle. Depending on the area of the building, the roof must withstand a certain amount of pressure and wind speeds.
In some areas of Arizona, for example, buildings may require stronger fasteners to resist winds of 150 mph and uplift pressure of 900 pounds per square foot. But, in other areas, the buildings may not need the same. Just remember that fasteners and wind loads requirements aren’t optional.
Another aspect that impacts the commercial roof replacement cost is the access. How easily can a roofer reach your commercial roof? How can materials be loaded? Each detail counts and adds to replacement costs.
Consider your old roof’s layers disposal as well. How will the many pieces of metal, asphalt, or plastic membrane leave the roof? You cannot ignore questions like this.
Can the Glendale re-roofing happen during business hours? Will customers and workers be bothered? Notice these factors before starting the project.
Last, but not least, we have building codes. These codes vary depending on the jurisdiction, but they ask roofing contractors to build roofs following specific requirements.
Building codes change over time to make roofing systems more resistant to climate conditions and wildlife.
If your commercial roof was installed years ago, your new roof will probably have more code requirements to meet. You have to hire a local roofing contractor who knows the building code and will follow these regulations.
