If you own or manage a commercial building, you likely understand the importance of maintaining a sturdy, reliable roof.
Charles Jimerson of CJ Commercial Roofing NJ has to say that “A new roof can provide a number of benefits, from increased energy efficiency to improved aesthetic appeal.”
But with so many different types of commercial roofing available, it can be difficult to know which one is right for your building.
So, what is the most common type of commercial roof? The answer depends on a number of factors, including the size and shape of your building, your budget, and your specific needs and preferences. However, there are a few types of commercial roofing that are more commonly used than others.
In this article, we’ll explore some of the most popular types of commercial roofing, as well as their pros and cons, to help you make an informed decision about your new roof.
Common Types of Commercial Roofs
If you’re in the market for a new commercial roof, you may be wondering what the most common type of commercial roof is.
There are several different types of commercial roofing systems available, each with its own unique set of advantages and disadvantages. Here are some of the most common types of commercial roofs you might consider:
Flat Roofing Systems
Flat roofs are a popular choice for commercial buildings because they are relatively inexpensive and easy to install. They are also low-maintenance and can last for many years with proper care.
Flat roofs can be made from a variety of materials, including asphalt, rubber, and PVC. However, they are not ideal for areas with heavy snowfall or rainfall, as water can accumulate on the roof and cause damage over time.
Metal Roofing
Metal roofing is another popular choice for commercial buildings. Metal roofs are durable, long-lasting, and can withstand harsh weather conditions. They are also energy-efficient and can help reduce heating and cooling costs.
Metal roofs can be made from a variety of materials, including steel, aluminum, and copper. However, they can be more expensive than other types of roofing systems.
Asphalt Shingles
Asphalt shingles are a popular choice for residential roofs, but they can also be used on commercial buildings. They are relatively inexpensive and easy to install, and they come in a variety of colors and styles. However, they are not as durable as other types of roofing systems and may need to be replaced more frequently.
Single-Ply Membrane Roofing
Single-ply membrane roofing is a popular choice for commercial buildings because it is lightweight, easy to install, and relatively inexpensive.
It is made from a single layer of synthetic material, such as PVC or TPO, and is designed to be watertight and long-lasting. Single-ply membrane roofing is also energy-efficient and can help reduce heating and cooling costs.
Spray Polyurethane Foam (SPF)
Spray polyurethane foam (SPF) is a popular choice for commercial buildings because it is lightweight, durable, and energy-efficient.
It is made by spraying a mixture of polyurethane foam and other chemicals onto the roof, creating a seamless, waterproof layer. SPF roofing systems can last for many years with proper care and maintenance.
Materials and Durability
When it comes to commercial roofing, there are several materials to choose from. Each material has its own set of benefits and drawbacks.
Some of the most common materials used for commercial roofing include rubber and synthetic membranes, metal varieties, and composite materials.
Rubber and Synthetic Membranes
Rubber and synthetic membranes, such as TPO and EPDM, are popular choices for commercial roofing due to their durability and cost-effectiveness.
These materials are lightweight, easy to install, and resistant to UV rays, punctures, and tears. They also provide excellent insulation, which can help reduce energy costs.
Metal Varieties
Metal roofing is another popular choice for commercial buildings. Steel and aluminum are the most common metal materials used for commercial roofing.
Metal roofs are known for their durability and longevity, with some lasting up to 60 years. They are also fire-resistant and require minimal maintenance. However, metal roofs can be expensive and noisy during heavy rain or hail.
Composite Materials
Composite roofing materials, such as slate roofing, are becoming more popular for commercial roofing due to their durability and aesthetic appeal.
Composite materials are made from a combination of materials, such as rubber, plastic, and wood fibers. They are resistant to weathering, cracking, and fading, and can last up to 50 years. Composite roofing is also eco-friendly and energy-efficient, making it a popular choice for environmentally conscious businesses.
Design and Style Considerations
When it comes to the design and style considerations of commercial roofing systems, there are a few key factors to keep in mind. These include the aesthetic appeal of the roof, as well as any architectural requirements that must be met.
Aesthetic Appeal
The appearance of a commercial roof is an important consideration, as it can impact the overall look of the building.
Many different styles and designs are available, including standing seam roofing, shingle look-a-likes, and simulated roofing slate. Each of these options has its own unique benefits and drawbacks, so it’s important to carefully consider which one is best for your specific needs.
Architectural Requirements
In addition to the aesthetic appeal of the roof, it’s also important to consider any architectural requirements that must be met.
For example, some buildings may require a specific type of roofing system in order to meet local building codes or zoning regulations. Additionally, the slope of the roof and the overall design of the building may impact the type of roofing system that is most appropriate.
Installation and Maintenance
Installation Process
When it comes to installing a commercial roof, the process can vary depending on the type of roof you choose. However, there are a few general steps that most installation processes follow.
First, the old roof will need to be removed and the surface will need to be cleaned and prepared for the new roof.
Next, the insulation will be installed, followed by the roofing material itself. Finally, the roof will be sealed and finished with any necessary details such as flashing or gutters.
It is important to hire a professional roofing contractor like CJ Commercial Roofing NJ, to handle the installation process. They will have the necessary equipment, knowledge, and experience to ensure that the installation is done correctly and efficiently.
Regular Maintenance and Repair
Once your commercial roof is installed, it is important to keep up with regular maintenance and repair to ensure its longevity.
This includes regular inspections, cleaning, and repairs as needed.
Regular inspections should be done at least twice a year, typically in the spring and fall. During these inspections, the roofing contractor will check for any signs of damage or wear and tear. They will also check for any potential issues such as leaks or drainage problems.
Regular cleaning is also important to prevent debris buildup and keep the roof in good condition. This can be done with a simple broom or leaf blower.
If any repairs are needed, it is important to address them as soon as possible to prevent further damage. This can include anything from small repairs such as patching a leak to larger repairs such as replacing a section of the roof.
Cost and Value
When it comes to commercial roofing, cost and value are important factors to consider. A new roof is a significant investment, and you want to make sure you are getting the most for your money. There are two main aspects to consider when it comes to cost and value: initial investment and long-term value.
Initial Investment
The initial investment for a commercial roof can vary depending on the type of roof you choose.
Some of the most common types of commercial roofing include single-ply roofing, built-up roofing, metal roofing, and modified bitumen roofing. The initial cost for these roofing systems can range from $3.50 to $10 per square foot.
While some roofing systems may have a higher initial cost, they may also provide better value in the long run.
For example, metal roofing may be more expensive initially, but it can last up to 50 years or more with proper maintenance. This means that you may save money in the long run by choosing a long-lasting roof.
Long-Term Value
When considering the long-term value of a commercial roof, it is important to think about factors such as replacement, longevity, and home value.
A roof that lasts longer will provide better long-term value, as it will need to be replaced less frequently. Additionally, a new roof can increase the value of your property, which can be beneficial if you are planning to sell in the future.
Choosing a long-lasting roof can also help you save money on maintenance and repairs. For example, a metal roof may require less maintenance than other types of roofing systems, which can save you money in the long run.
Climate and Environmental Impact
Climate Adaptability
When choosing a commercial roof, it is important to consider the local climate. Different types of roofs are better suited for different climates.
For example, if you live in an area with heavy snowfall, a flat roof may not be the best option as it can accumulate snow and cause damage to the building. On the other hand, a sloped roof can help to shed snow and prevent damage.
Eco-Friendly Options
In recent years, there has been a growing trend towards eco-friendly roofing options. These options not only help to reduce the environmental impact of the building, but they can also help to reduce energy costs.
One popular eco-friendly option is a green roof, which uses vegetation to manage stormwater runoff, reduce energy consumption, provide wildlife habitat, and improve air quality.
Another option is to use recyclable materials in the roofing system. This can help to reduce waste and minimize the environmental impact of the building.
Additionally, some roofing systems now come with built-in solar panels or shingles, which can help to generate electricity and reduce energy costs.
Building-integrated photovoltaics (BIPV) is another option that can be used to reduce energy costs.
BIPV systems are integrated into the building’s envelope and can generate electricity from sunlight. This can help to reduce the building’s reliance on traditional energy sources and lower energy costs.
Advanced Roofing Options
If you’re looking for more advanced roofing options, there are a few choices that you should consider. In this section, we’ll take a look at photovoltaic solar panels and green roofing.
Photovoltaic Solar Panels
One of the most exciting advancements in commercial roofing is the use of photovoltaic solar panels. These panels are designed to convert sunlight into electricity.
This electricity can be used to power your building. Not only do these panels help reduce your energy bills, but they also help reduce your carbon footprint.
There are a few different types of photovoltaic solar panels. The most common type is the traditional solar panel, which is made up of a series of cells that are connected together. These cells are typically made from silicon, which is a highly efficient material for converting sunlight into electricity.
Another type of photovoltaic solar panel is the solar shingle. These shingles are designed to look like traditional roofing shingles, but they contain photovoltaic cells that generate electricity. Solar shingles are a great option for buildings that want to generate their own electricity but don’t want to install traditional solar panels.
Green Roofing
Green roofing is another advanced roofing option that you should consider. These roofs are designed to be covered in vegetation. The vegetation helps reduce the amount of heat that is absorbed by the roof, which can help reduce your energy bills and improve the energy efficiency of your building.
Green roofs are typically made up of several layers. The bottom layer is a waterproof membrane that helps protect the building from water damage. On top of this membrane, a layer of soil is added. Then, the soil is covered in vegetation.
One of the benefits of green roofing is that it is recyclable. When it’s time to replace your roof, the vegetation and soil can be recycled or composted. Additionally, green roofs can be Energy Star certified. This means that they meet certain energy efficiency standards.
