Commercial Roofing Systems You Need to Know About

When it comes to commercial buildings, the roof is one of the most important components. It not only protects the interior of the building from harsh weather conditions, but it also plays a crucial role in maintaining the structural integrity of the entire building. That's why choosing the right roofing system for your commercial property is essential. In this blog, we will discuss five types of commercial roofing systems that are commonly used and their unique features.

Built-Up Roofing (BUR)

This roofing style comprises several layers of bitumen (either asphalt or coal tar) interspersed with reinforcing fabric layers like fiberglass or organic felts. These layers are then topped off with a layer of gravel or a reflective coating to protect against UV rays.

One of BUR's main advantages is its durability. The multiple layers make it highly resistant to damage from foot traffic and extreme weather conditions. It also has excellent waterproofing capabilities, making it ideal for flat or low-sloped roofs.

Modified Bitumen Roofing

This roofing system combines asphalt with modifiers such as APP (atactic polypropylene) or SBS (styrene-butadiene-styrene) to boost performance and flexibility. Modified bitumen roofs can be installed using different methods, including torch-applied, cold-applied, or self-adhered sheets. They offer excellent resistance against water and fire damage and have a longer lifespan compared to traditional BUR systems.

TPO Roofing

Thermoplastic polyolefin (TPO) is made of a blend of ethylene-propylene rubber and polypropylene, making it highly durable and flexible. TPO roofs are installed by heat-welding the seams together, creating a watertight seal. They also have excellent reflective properties, which can help reduce energy costs for commercial buildings. Additionally, TPO roofing is resistant to chemicals and UV rays, making it a suitable option for buildings with rooftop equipment.

EPDM Roofing

Ethylene propylene diene monomer (EPDM) roofing is another popular single-ply membrane system. It is made of synthetic rubber and comes in large sheets that are mechanically attached or adhered to the roof deck. EPDM roofs are known for their exceptional durability and resistance against extreme weather conditions. They also have excellent insulation properties, which can help reduce heating and cooling costs for commercial buildings. However, they may be more prone to punctures compared to other roofing systems.

Metal Roofing

Metal roofing has been used in commercial buildings for decades due to its strength and longevity. It is available in different materials, such as steel, aluminum, copper, or zinc. Metal roofs can be installed as standing seam panels or shingles and come in various colors and finishes.

One of the main advantages of metal roofing is its low maintenance requirements. It is also highly resistant to fire, wind, hail, and extreme temperatures. However, metal roofs may be more expensive upfront than other roofing systems.
