Most commercial buildings, such as grocery stores, shopping malls, and offices, have flat roofing structures. They’re popular because of their longevity and durability, giving building owners and property managers peace of mind regarding occupants’ safety and their company’s reputation for professionalism. Although flat roofs last for decades, roof restoration or replacement is inevitable.
If your roofing system shows signs of severe wear and tear or deterioration, the best thing to do is call professionals to analyze the damage and confirm the best course of action. Consider these industry-trusted roof membrane types if it’s time to upgrade your structure. Older materials, like modified bitumen, are on the way out and need to be retired. Weigh these efficient commercial flat roofing materials’s pros and cons and determine which is most compatible with your facility.
Thermoplastic polyolefin, or TPO, is a single-ply rubber roofing material. Different types of rubber and other synthetic fillers like talc, fiberglass, and carbon fiber are combined. TPO roofing is essentially three parts covering the surface in a monolithic layer: the bottom layer is the TPO compounded pinnacle ply. There’s polyester or reinforced fabric (scrim) in the middle, and the TPO polymer base is on top.
Silicone roofing is a fluid-applied membrane that provides excellent long-term protection. This commercial roof type is silicone metal, the second most common element on earth. Therefore, it’s plentiful and inexpensive. Silicone costs between $2 to $3.50 per square foot. Silicone can bring any flat roof back to life.
Ethylene propylene diene monomer, or EPDM, is another rubber commercial flat roof material. It also consists of natural gas, oil, and synthetic materials. EPDM is one of the most cost-effective roof membrane types, at an average of $75 to $450 per square (100 square feet), so it’s cheaper than other commercial flat roofing materials. EPDM has been used since the ’60s and has continuously gained popularity, making it one of the most common types of commercial roofing systems in the U.S.
Built-up commercial flat roofing materials are popular for low-slope or flat roofs on commercial buildings. These systems consist of multiple layers of materials, including asphalt, bitumen, and reinforcing fabrics like fiberglass or felt. Contractors apply these layers in a staggered fashion, creating a strong and waterproof membrane. Gravel or a reflective coating is often added to enhance durability and energy efficiency. Built-up roofing systems provide excellent weather resistance, longevity, and can accommodate rooftop equipment, making them a versatile and enduring solution for commercial properties.
