Commercial Roof Styles: An Essential Guide for Business Owners
To protect your business’s roof, it’s important to have a general knowledge of the different commercial roofing styles available. Depending on their design, application, and other advantages, several types are available.
For commercial owners, the type of roof is a crucial consideration. There are various roofing types to choose from, including metal, single-ply membrane, and built-up roofing systems. Each offers its advantages and plays a big role in protecting your business. Learning and understanding these types can help you make an informed decision.
Commercial Roofing Materials and Systems
Single-Ply Roofing Membranes
SiSingle-ply roofing membranes are popular for their durability and cost-effectiveness. Several different options are available, such as TPO (Thermoplastic Polyolefin), PVC (Polyvinyl Chloride), and EPDM (Ethylene Propylene Diene Monomer).
Each material offers its benefits. TPO and PVC are best known for their heat-reflective properties, while EPDM is great for holding up in harsh weather.
Built-Up Roofing (BUR) Systems
Built-up roofing (BUR) Systems, called “tar and gravel” roofs, are a typical choice for commercial establishments. These systems consist of alternating layers of bitumen and reinforcing fabrics topped with a layer of gravel or stone. This approach protects against water and UV damage, making the roof last longer with minimal maintenance.
Metal Roofing Systems
Metal roofs offer durability, energy efficiency, and aesthetic appeal. They may be made of steel, aluminum, or copper and last 40 to 70 years.
Metal roofs are popular because they are:
- Durable
- Resistance to many roof issues, like fire, pests, etc.
- Energy efficient
Modified Bitumen Roofing
Modified bitumen roofing systems are an evolution of the BUR system. These roofing structures use a mixture of asphalt and rubber to create a strong, weather-resistant, and flexible roof surface area. They can be applied via torch, cold application, or self-adhesive, and they’re a cost-effective solution with easy maintenance.
Green Roofing Solutions
Green roofs are an eco-friendly approach to commercial roofing systems. It’s a layer of vegetation planted on a rooftop that gives insulation and improves air quality and natural beauty. Green roofs support various plants, from grasses to trees, but can vary depending on what the roof can support.
Extensive and intensive are the two types of green roofing options. Extensive green roofs have a shallow layer of soil for low-growing plants. This is a lightweight option with low maintenance needs.
Intensive green roofs have a deeper soil layer that supports a wider plant variety but will require more maintenance and a strong roofing structure.
Considerations for Commercial Roof Styles
Low-Slope vs. Pitched Roofs
One of the first things to consider when choosing a roofing style is whether you want a pitched or low-slope roof. A low-slope roof (also called a flat roof) needs less material and can be cheaper. The big concern with this type of roofing is draining issues, so you must have a good design and keep up with all required maintenance.
Pitched roofs drain well but are most expensive to maintain and build.
Energy Efficiency and Insulation
Insulation and energy efficiency are two other significant factors to consider when selecting a roof. A metal roof reflects sunlight, reduces heat absorption, and lasts 40-70 years.
For insulation needs, be sure to choose the right insulation under the roofing material. Because this can reduce the amount of energy consumed and maintain a comfortable temperature.
Below are the pros and cons of two different types of roofing materials:
Metal Roofs
- Pros: High durability, energy-efficient, low maintenance
- Cons: Higher upfront cost, noise during rain or hailstorms
EPDM Roofs (Ethylene Propylene Diene Terpolymer)
- Pros: Good insulation properties, easy to install, cost-effective
- Cons: Less durable than metal, may require more frequent maintenance
Weather and Environmental Factors
Understanding the local weather and climate is a big consideration to take into account before picking a roof style. Buildings in areas with high temperatures and UV light must choose a roof with UV-resistant properties.
A pitched roof will benefit buildings in areas with heavy snow and rain by helping with proper drainage and preventing leaks. However, you must also remember local building codes and regulations, which can impact the chosen design.
There are many factors to consider when choosing a roof design. Take into account the options to make the best-informed decision.
Roof Installation and Maintenance
Another vital factor is picking a professional roofing contractor for your roof installation. To select the best contractor, ensure they have:
- Experience: Choose an experienced contractor who has installed various roof systems
- License and insurance: Ensure they possess the required licensing and insurance
- References: Check for positive customer reviews and previous work samples
- Written estimate: Receive a thorough written quote for the project
Regular Roof Maintenance
Regular maintenance is critical for extending the lifespan of your roof. Here are a few ways to keep up with the needed maintenance:
- Inspect the roof: Perform a visual inspection at least twice per year or after extreme weather events
- Clean debris: Keep the roof surface and gutters free from dirt, debris, and flora
- Monitor drainage: Ensure gutters and drains are unclogged and functioning properly
- Trim nearby trees: Prune trees surrounding your building to minimize potential debris on the roof
Longevity and Roof Lifecycle
It’s no secret that different roof systems have different lifespans. Check out the estimated life spans for the most popular roof types:
| Roof System | Estimated Lifespan |
|
Single-ply membranes |
25 – 35 years |
|
Metal roofing |
40 – 70 years |
|
Built-up roofing (BUR) |
20 – 30 years |
|
Green roofs |
30 – 50+ years |
With the proper materials, installation, and upkeep, the years of your roof will increase, and you will have reliable coverage for a long time.

Over the years, there has been more focus on sustainable and energy-efficient solutions for roofing. One option is solar-ready roofing, which is where the roof is designed to support adding solar panels.
This type of roof can help reduce energy costs while being kind to the environment. However, you must know the roof’s weight-bearing capacity to ensure it’s suitable for this type of installation.
This is where working closely with a roofing professional is essential! Investing in an energy-generating roof can lead to savings and benefits for many years.
Cool Roofing Technologies
Cool roofing technologies are another great benefit that minimizes heat absorption and increases heat reflection. This type of roof uses lighter-colored materials that help to lower the surface temperature on the roof. This helps the interior of the building stay cooler, and reducing the need for air conditioning. Moreover, it also lowers energy costs.
- Reduced energy consumption
- Prolonged roof lifespan
- Greater thermal comfort indoors
- Decreased urban heat island effect
Choosing suitable cool roofing material depends on your building’s location and structure. Some popular options are:
- Cool modified bitumen or built-up roofing (BUR)
- Cool single-ply membranes (e.g., TPO or PVC)
- Cool metal roofing with reflective coatings
As you can see, there are innovative roofing options. Consider these solutions for your commercial roof and see how easy it can be to lower energy costs and increase overall performance. Remember that working with a trusted roofing company is key!
