Roofs are essential to protecting buildings from Canada’s harsh weather, so choosing the right commercial roofing system is an important decision for property owners. Among the many options available, flat roof systems stand out for their practicality and adaptability.
This guide details the different types of commercial flat roof systems, providing a nuanced understanding for property owners looking for the best roofing solution for their buildings.
Types of commercial flat roof systems
EPDM (ethylene propylene diene monomer)
EPDM is ideal for commercial flat roofs due to its superior durability and weather resistance. This synthetic rubber membrane exhibits excellent flexibility and expands and contracts in response to temperature changes. A notable benefit of EPDM roofing is that it has an easy installation and repair process, making it a cost-effective option for commercial properties.
maintenance tips: Regularly inspecting for signs of wear, addressing any holes or tears immediately, and ensuring proper drainage are important aspects of EPDM roof maintenance. Additionally, applying a protective coating can increase UV resistance and extend the lifespan of your roof.
TPO (thermoplastic olefin)
TPO roofs are becoming increasingly popular in commercial roofing due to their energy efficiency and reflective properties. This single layer membrane is heat welded during installation to form a seamless waterproof barrier. These roofs are recognized for their resistance to UV light and chemical exposure, making them a durable, low-maintenance option.
maintenance tips: Regular inspections to check the integrity of seams and promptly address signs of deterioration are critical to TPO roof maintenance. Cleaning reflective surfaces to maximize energy efficiency and checking them regularly for damage or holes should be part of your regular maintenance schedule.
PVC (polyvinyl chloride)
Another thermoplastic membrane option, PVC roofing offers superior durability, chemical and fire resistance. These roofs are known for their strength and ability to withstand extreme weather conditions, making them suitable for Canada’s diverse climate. These commercial roofing systems are also puncture and tear resistant, ensuring a long life with minimal maintenance.
maintenance tips: Regular inspections to identify and repair seam problems and cleaning to remove debris and prevent algae and mold growth are essential to PVC roof maintenance. Applying a UV protective coating increases the material’s resistance to sunlight and contributes to its longevity.
BUR flat roof and modified asphalt
Built-up roofing (BUR) and modified asphalt roofing systems include multiple layers of asphalt and reinforcing fabric to create a robust and durable roofing solution. BUR roofs consist of alternating layers of asphalt and reinforcement layers, providing excellent waterproofing and durability. Modified asphalt combines the benefits of BUR with modern polymer modifications to improve performance.
maintenance tips: It is important to regularly inspect BUR and modified asphalt roofs for signs of wear and tear, especially in high-traffic areas. Prompt repair of hole and seam problems and regular resealing can extend the life of these commercial roofing systems.
metal roof
Metal roofing is a versatile option for commercial flat roofing, offering durability and a modern aesthetic. Common materials include steel, aluminum, and copper. These roofs are popular due to their long lifespan, fire resistance, and low maintenance requirements.
maintenance tips: For metal roofs, regular inspections are very important to identify and address any signs of corrosion or damage. Cleaning to remove debris and applying a protective coating can extend the life of your metal roof, especially in areas prone to harsh weather conditions.
