Single Ply Roof
Single-ply membrane roof is a popular roofing option for commercial buildings due to its affordability, energy efficiency, and ease of installation. This roofing system is composed of a single layer of synthetic material that is either mechanically attached or fully adhered to the roof substrate.

Spray Polyurethane Foam Roofing (SPF)
SPF commercial roofs are composed of a layer of foam that is sprayed onto the roof surface, followed by a protective coating. This roof system provides excellent insulation and can help reduce energy costs for heating and cooling a building. The foam layer conforms to the shape of the roof, creating a seamless, monolithic surface that can withstand harsh weather conditions, including high winds and heavy rainfall.
- Installation: $4 to $7
- Repair: $6 to $12
- Replacement: $7 to $11
Polyvinyl Chloride (PVC) Roofing
A PVC roofing system is composed of a single-ply membrane made of a thermoplastic material that is reinforced with polyester.
PVC roofing is highly resistant to water, fire, chemicals, and UV radiation, making it ideal for buildings in harsh climates or industrial areas. The roofing material can be manufactured in a range of colors and thicknesses, allowing for customization and flexibility in design.
- Installation: $6 to $9
- Repair: $7 to $13
- Replacement: $6 to $9
Ethylene Propylene Diene Monomer (EPDM) Roofing
EPDM roofing system is composed of a single-ply membrane made of synthetic rubber, which is mechanically attached or fully adhered to the roof substrate. This roofing can be installed over most existing roofing systems and requires minimal maintenance.
- Installation: $4.50 to $5.50
- Repair: $3 to $12
- Replacement: $3 to $7
Modified Bitumen Roof Systems
These roofing systems are made up of layers of asphalt and polymer-modified materials that provide flexibility, strength, and resistance to damage from UV rays, extreme temperatures, and wind. Modified Bitumen Roof Systems can be installed using a variety of methods, including torch-applied, cold-applied, or self-adhered, depending on the specific application and building requirements.
- Installation: $2.50 to $4.00
- Repair: $4.00 to $7.50
- Replacement: $4 to $8
Built-Up Bituminous (BUR) Roofing
Built-Up Bituminous Roofing (BUR) is a type of flat or low-slope roofing system that has been in use for over a century. BUR consists of multiple layers of asphalt and felt materials, applied in hot or cold liquid form and then mopped or rolled onto the roof surface.
- Installation: $4 to $7
- Repair: $4 to $8
- Replacement: $11.50 to $14.50
Thermoplastic Polyolefin (TPO) Roofing
TPO roofing is made up of a single-ply membrane that is typically white, which reflects sunlight and helps reduce cooling costs.
- Installation: $6 to $9
- Repair: $5.50 and $8.75
- Replacement: $8 to $12
Metal roofs are made up of metal panels, typically aluminum or steel, that are designed to interlock with each other and provide a watertight seal. These roofing systems can withstand extreme weather conditions, including heavy rain, high winds, and snow, and are resistant to fire, pests, and rot.
- Installation: $5 to $10
- Repair: $1 to $5
- Replacement: $8 to $12

FAQs About Commercial Roofing Systems Costs
How do you calculate the price per square foot of a roof?
To calculate the price per square foot of a commercial roof, you first need to determine the total square footage of the roof. This can be done by measuring the length and width of the roof and multiplying those numbers together.
For example, if the length of the roof is 100 feet and the width is 50 feet, the total square footage of the roof would be 5,000 square feet.
Once you have determined the total square footage of the roof, you can then divide the total cost of the project by the total square footage to get the price per square foot. For example, if the total cost of a commercial roofing project is $50,000 and the total square footage of the roof is 5,000 square feet, the price per square foot would be $10.
What type of roof is typically used on commercial buildings?
Commercial flat roofs are one of the most common types of roofs used on various buildings. This is because flat roofs are easy to construct, cost-effective, and provide a large, level surface that can be used for a variety of purposes, such as HVAC units, solar panels, and rooftop gardens.
What kind of roof would a low-cost commercial building have?
The type of roof used on a low-cost commercial building can vary based on several factors, such as the size of the building, its intended use, and the local climate. Generally, a low-cost commercial building may have a simple and cost-effective roofing system such as a built-up roofing (BUR), metal roofing, or a single-ply roofing membrane.
What percentage of a building is the roof?
According to the National Roofing Contractors Association (NRCA), the roof typically represents about 10% to 12% of a building’s total construction cost.
The exact percentage can vary depending on the type of roofing as well as its size and shape. Local labor and material costs are huge factors too.
