Types of Commercial Flat Roofing Systems You Should Know

December 5, 2023

Choosing the right commercial roofing system is a critical decision for property owners, as the roof is essential in safeguarding structures from the demanding Canadian weather. Flat roofing systems stand out for their practicality and adaptability among the plethora of other options.

This guide delves into various types of commercial flat roofing systems, providing a nuanced understanding for property owners seeking the optimal roofing solution for their buildings.

Types of Commercial Flat Roofing Systems

EPDM (Ethylene Propylene Diene Monomer)

EPDM is a great choice for commercial flat roofing due to its exceptional durability and weather resistance. This synthetic rubber membrane demonstrates impressive flexibility, allowing it to expand and contract with temperature fluctuations. A notable advantage of EPDM roofing is its straightforward installation and repair processes, making it a cost-effective option for commercial properties.

Maintenance Tips: Regular inspections for signs of wear, promptly addressing any punctures or tears, and ensuring proper drainage are key aspects of maintaining an EPDM roof. In addition, applying a protective coating can enhance UV resistance and extend the lifespan of the roof.

TPO (Thermoplastic Olefin)

TPO roofs are becoming increasingly popular in commercial roofing due to their energy efficiency and reflective properties. This single-ply membrane, heat-welded during installation, creates a seamless and watertight barrier. These roofs are recognized for their resistance to UV rays and chemical exposure, making them a durable and low-maintenance option.

Maintenance Tips: Periodic inspections to check for seam integrity and promptly address any signs of degradation are crucial for TPO roofing maintenance. Cleaning the reflective surface to maximize energy efficiency and conducting routine checks for any damage or punctures should be part of a regular maintenance schedule.

PVC (Polyvinyl Chloride)

PVC roofs, another thermoplastic membrane option, offer excellent durability and resistance to chemicals and fire. Known for its strength and ability to withstand extreme weather conditions, these roofs are suitable for the diverse Canadian climate. These commercial roofing systems also demonstrate resistance to punctures and tears, ensuring a long lifespan with minimal maintenance.

Maintenance Tips: Regular inspections to identify and repair any seam issues and cleaning to remove debris and prevent algae or mould growth are integral to PVC roof maintenance. Applying a UV protectant coating can enhance the material’s resistance to sunlight and contribute to an extended lifespan.

BUR Flat Roof & Modified Bitumen

Built-Up Roofing (BUR) and Modified Bitumen roofing systems involve multiple layers of bitumen and reinforcing fabrics, creating a robust and durable roofing solution. BUR roofs consist of alternating layers of bitumen and reinforcing plies, offering exceptional waterproofing and durability. Modified bitumen combines the advantages of BUR with modern polymer modification for enhanced performance.

Maintenance Tips: Regular inspections for signs of wear or damage, especially in high-traffic areas, are crucial for BUR and Modified Bitumen roofs. Prompt repairs of any punctures or seam issues and periodic resealing can contribute to the longevity of these commercial roofing systems.

Metal Roof

Metal roofing is a versatile option for commercial flat roofs, offering durability and a modern aesthetic. Common materials include steel, aluminum, and copper. These roofs are popular for their longevity, resistance to fire, and low maintenance requirements.

Maintenance Tips: Regular inspections to identify and address any signs of corrosion or damage are crucial for metal roofs. Cleaning to remove debris and applying protective coatings, especially in areas prone to harsh weather conditions, can enhance the lifespan of a metal roof.
