5 Types of Commercial Roofing
Choosing the right roof for your building depends on many factors. You’re likely to have expectations when it comes to characteristics such as energy efficiency, durability, and environmental impact, but budget is also often one of the main deciding factors. Let’s take a closer look at the 5 main types of commercial roofing and their pros and cons.
Featuring rubber sheets that are mechanically or chemically adhered to insulation, single-ply membrane roofing is affordable and relatively durable. Single-ply membrane roofs are commonly used for flat roofs and promote exceptional fire protection when installed with fire retardant chemicals. As one of the most popular commercial roofing applications, these roofs have been tested in a wide range of climates and geographic areas.
Spray Polyurethane Foam
Spray polyurethane foam roofing, often referred to as SPF roofing, is an environmentally-conscious type of commercial roofing that is also used in industrial and manufacturing applications. This roofing technology is nearly 60 years old, and while it is not the most popular commercial roofing material, it is incredibly versatile. SPF roofs are suitable to any climate and have a lifespan that can extend beyond 50 years. The costs can range between $3-8 per square foot depending on the size of the roof and other factors. For energy efficiency, durability, and environmental impact, SPF roofing is a great choice.
Metal roofing is certainly not new in the commercial roofing industry. Generally made from corrugated galvanized steel, these roofs are surprisingly low weight and can be applied over existing roofs. Though steel roofs are the most common, aluminum and tin options are also available. Metal roofs tend to be a little more expensive and range upwards of $8-10 per square foot, but they offer many design advantages. First, metal roofs are available in a range of materials and colours, and they are also very weather resistant standing up well to wind and snow. These are also energy efficient roofs that offer exceptional fire protection.
Most often associated with residential applications, shingle roofs are a great option for commercial buildings with sloped roofs. As you have a lot of variety in shingles for residential properties, so is true of commercial shingles – asphalt is common, but you can also get wood, slate, metal, ceramic, and other varieties of shingle commercial roofs. These roofs are stylish, affordable, and easy to maintain.
Finally, built-up commercial roofing or tar and gravel roofs feature layers of asphalt, tar, and fabric covered with gravel. This is an affordable commercial roofing application that is also easy to maintain. Additionally, tar and gravel roofs are highly durable and when maintained properly can last up to 40 years.
