Types of Commercial Roofing

Depending on a building’s size, structure, type of a business, and budget, there are many different types of commercial roofing systems available. Knowing about the different types of commercial roofing systems will facilitate your decision-making process:


  • Metal Roofs: metal roofing is among the most preferred options for commercial property owners. When installed right, a metal roof can offer decades of efficient performance and the desired look.

  • TPO (Thermoplastic Polyolefin): TPO is a single-ply roofing membrane and is one of the fastest-growing commercial roofing systems. This type of roofing has a natural reflective surface to reflect UV rays.

  • PVC (Polyvinyl Chloride) Roofing: Made from polyvinyl chloride (or plastic), PVC is an excellent single-ply roofing solution. It is a cool roof membrane that contains a lower percentage of oil and petroleum and is commonly used on commercial buildings.

  • Green roofing: A green roof can help you lower your energy costs significantly. It consists of a tough waterproof membrane entirely covered by green plants. These sustainable and aesthetically-pleasing roofs improve air quality and can even lower building energy costs.

  • BUR (Built-Up Roof): BUR is made by alternating layers of tar and gravel. The number of layers of this commercial roof would affect its durability and cost. BUR is among the oldest and most flexible commerical roofing types, which is budget-friendly and quite easy to repair.


Difference Between Commercial and Residential Roofing

The primary purpose of both commercial and residential roofs is the same, which is to protect your property from the elements. The main differences between these two kinds of roofing systems include the following:


The slope of the roof

As homes are smaller than commercial buildings, they typically have a steep slope roof visible from the ground, whereas due to the size and structure, commercial buildings tend to have flat or slightly sloped roofs.


Materials used

The types of roofing materials can vary significantly depending on the type of roofing. Residential roofs are often made of shingles, tiles, and slate, and commercial materials consist of a single-ply membrane or bitumen.


Installation and maintenance

It takes only a few days to install residential roofs, while commercial roofs can take significantly longer. Also, the maintenance of commercial roofs is often more complex than residential roofs.


Common Commercial Roofing Issues

Below are some of the issues with commercial roofs that need to be addressed promptly before causing more severe problems:

  • Leakage: Roof leaks are common with commercial roofs. When water or moisture gets through your roof, your building is at risk of moulding.

  • Membrane damage: The membranes used in commercial roofs can split, tear, crack or expose open laps over time due to ageing or defective material.

  • Drain issues: Drains, gutters, scuppers or flashing around drains tend to get loose or may require additional sealing to prevent water from entering the building.
