What are industrial roofs made of?

Aug 25

Residential roofs and industrial roofs are not the same things. Flat roofs in Toronto are more common in industrial buildings. These buildings must be able to withstand the much greater weight. The roof protects something different. 


All kinds of goods are housed in industrial buildings. Some of them require precise temperature control and other accommodations. A roof that does a good job is essential for industrial properties. You need to be familiar with the basic types of roofs.


TPO (thermoplastic polyolefin) is a single-ply membrane, which is then rolled onto the roof's surface. It is available in sheets measuring between 10 and 20 feet wide. The sheets are rolled and heat-welded together using a welding robot. 


TPO is usually white and provides UV reflectivity, which aids indoor cooling systems. It is most commonly used on flat roofs. It is easy to install and very durable. TPO roofs can last for up to 20 years.

Modified bitumen

Modified bitumen, also known as torch-down roofing or single-ply roofing membranes, is often used for flat roofs. This single-ply membrane consists of multiple layers of adhesive, reinforced fiberglass, or polyester. Because it is one piece, it is called single-ply. 


The material is heated using a torch and rolled onto the surface measuring three feet wide. Gravel is often used to protect the modified bitumen roof from ultraviolet rays. These roofs can be used over other roofing materials and are flexible in extreme temperatures. They last between 10-20 years.

Built-up Roofing

Flat roofs have been using built-up roofing for more than a century. Although these roofs look similar to Modified Bitumen but are made from multiple layers, they can be customized to your specifications. They can be "built up" in multiple layers. 

This could include tar, asphalt, and fabric-like material like polyester and gravel. It reflects ultraviolet rays when it is covered with gravel. It is durable, cost-effective, and easy to maintain.


Metal roofing is commonly used for pitched industrial roofs. Metal roofing comes in many options. Metal roofing materials include aluminum, copper, and tin. There are many options for metal roofing panels. Metal roofing today is solid and rust-resistant. It lasts a long time.


Metal panels can be attached to the roof with either an exposed-fastener system that is less durable or a hidden fastener system. Hidden fasteners are used for standing seam metal roofing. This gives you a sturdy roof with a distinctive look. Each panel has raised seams that extend the entire length.

Slate roofing

Since ancient times, slate roofing has been used. Slate can be found today in many colors and styles. Pitch roofs are made of slate. They are fire resistant and can last longer if properly installed and maintained.

Asphalt Shingles

Although asphalt shingles are most commonly used for roofing homes, they can also benefit businesses. Shingles today are made to resist impact damage and can last for up to 30+ years.
