Commercial Roof Replacement Cost In Arizona: 7 Things to Consider

Commercial roofs are an essential aspect of any building, whether it be a warehouse, office building, or residential complex. How much should you budget for a new commercial roof when the time comes?

How Much Is the Commercial Roof Replacement Cost in the US?

The price of replacing a commercial roof depends on a number of factors. Commercial roof replacement costs might range from $5,000 to $50,000 depending on these various aspects.

Installing a conventional single-ply roof typically costs between $3.50 and $7.50 per square foot in labor and materials for an ordinary 20,000 square foot commercial roof.

Factors that Affect the Cost of Commercial Roof Replacement

Let’s take a closer look at the variables that affect the final cost to get a better idea of how much replacing the roof system on commercial buildings will cost.

Size and Materials

The size and materials you select for your new roofing system all impact the cost. Roofs with larger square footage will cost substantially more than roofs with fewer square feet. Therefore, replacing the roof of a smaller apartment building will be less expensive than replacing that of a large shopping center.

Costs are generally determined by the size of your roof and the cost per square foot of the roofing material you choose. Numerous roofing materials are effective and protect your foundation, such as metal roofs. The cost of roofing materials varies depending on their durability and longevity.

Roof Angle

You generally get two types of roof angles:

  • Flat or low-sloped roofs
  • Pitched or sloped roofs

The majority of commercial structures have flat roofs. Although commercial flat roofs seem, well, flat, they aren’t really flat. The modest slope found on most flat roofing systems directs precipitation toward the gutter system.

Commercial flat roof replacement often costs less than sloping roof replacement in terms of cost. Given that they do not have to balance on a steep structure, contractors find flat roofs safer to navigate and easier to manage.

Each roof has materials beneath the finished roof or “underlayment.” Underlayment options include:

  • Cover board
  • Insulation
  • Roof structure (Metal, concrete, or wood deck)
  • Additional substance materials

A roofing contractor can tell the state of the substructure materials just by the way a roof “feels.” However, it is also possible to identify trapped moisture using moisture detecting equipment.

Accessibility Factors

When replacing your current commercial roofing system, the price includes labor costs. The ease of access to your building will influence how challenging it is for a flat roof contractor to install the new roof. Factors affecting accessibility include:

  • Property access
  • Building height
  • Material storage areas
  • Occupancy

A three-story building’s roof replacement will be less expensive than one on a skyscraper since cranes are required to move materials to the top of higher structures. Costs can be reduced by bringing materials to the location and storing them close by. The accessibility of your commercial building may be more difficult if it’s located in a crowded downtown area.

Construction might have to take place before or after typical working hours, adding to the cost, to meet tenants’ comfort, safety, and health.

Commercial Area

Code Requirements

State, local, and regional construction codes apply to every commercial building. Roofing codes can affect things such as:

  • Wind loans
  • Fire resistance
  • Ventilation
  • Insulation
  • Decking or substrate
  • Slope dimensions

Local Climate

Your final cost will also be influenced by the temperature and weather of the area in which your commercial building is situated. To keep the structure secure, the roof might need a more durable kind of roofing fastener if you live in a region that experiences severe winds. Your choice of material could also be influenced by the local climate.


Commercial Roof Replacement Contractor

The warranty is the last factor to take into account when estimating the cost of new commercial roofing systems. When you invest a lot of money in upgrading your commercial roof, you want to be sure you’re protected in case something goes wrong. In terms of roofing warranties, you’ll often have a few alternatives to pick from.
