When it comes to commercial roofing, knowing what type of roof you have is the first step in knowing how to maintain, repair and even replace your roof when the time comes. In this brief article, we will identify the most common types of commercial roofing materials.
1. Built-Up Roofing (BUR):
Built-Up Roofing, commonly known as BUR, is a traditional and reliable roofing system. It consists of multiple layers of bitumen (asphalt or coal tar) alternated with reinforcing fabrics, such as fiberglass or organic mats. BUR provides excellent waterproofing and durability, making it suitable for low-slope or flat roofs.
2. Modified Bitumen (MB):
Modified Bitumen roofing, also commonly referred to as “ModBit” is a modern evolution of BUR, combining asphalt with modifiers like APP (Atactic Polypropylene) or SBS (Styrene Butadiene Styrene) to enhance elasticity, flexibility, and durability. This type of roofing material is often applied in multiple layers or as a single-ply sheet, offering resistance to UV rays and harsh weather conditions.
3. Ethylene Propylene Diene Monomer (EPDM):
EPDM is a synthetic rubber roofing material that has gained popularity due to its durability and cost-effectiveness. It comes in large sheets and is installed using adhesive or mechanically fastened. EPDM offers excellent resistance to UV radiation, ozone, and varying temperatures, making it suitable for a wide range of climates.
4. Thermoplastic Olefin (TPO):
TPO roofing membranes are a popular choice for commercial buildings due to their energy efficiency and ease of installation. TPO is a single-ply roofing material that is highly reflective, reducing heat absorption and lowering cooling costs. It provides excellent resistance to UV radiation, chemicals, and punctures, making it a durable option.
5. Polyvinyl Chloride (PVC):
PVC roofing is another single-ply membrane that offers exceptional durability and resistance to chemicals, flames, and weathering. PVC roofs are known for their energy efficiency, as they reflect sunlight and minimize heat transfer into the building. They are typically installed using heat-welding techniques, ensuring secure and watertight seams. PVC roofs also offer an additional level of safety and protection in that many PVC roof products are self-Extinguishing. This means that unlike other membranes, a PVC roof will not continue to burn if ignited by an external source. Making it a great choice of membrane for a variety of facilities.
6. Metal Roofing:
Metal roofing systems, including steel, aluminum, and copper, are widely used in commercial buildings due to their longevity and aesthetic appeal. Metal roofs are durable, fire-resistant, and can withstand extreme weather conditions. They come in various styles, including standing seam, corrugated panels, and metal shingles, offering versatility in design.
7. Green Roofing:
Green roofing systems are gaining popularity as environmentally friendly options for commercial buildings. These roofs incorporate vegetation, providing benefits such as improved insulation, stormwater management, and enhanced air quality. Green roofs require specialized design and installation to ensure proper drainage and structural support.
Choosing the right commercial roofing material is a crucial decision that impacts the performance, energy efficiency, and lifespan of a building. The various options available, such as Built-Up Roofing, Modified Bitumen, EPDM, TPO, PVC, metal, and green roofing, cater to different needs and requirements. It is essential to consider factors like weather conditions, building design, and budget when selecting the most suitable roofing material for your commercial property.
