Types of commercial roofs:
Modified bitumen is asphalt roofing material with added membranes of fiberglass or polyester. This gives the roof extra strength and this compound is ideal for commercial buildings that have roofs that are either flat or have a low slope. Modified bitumen is water-resistant and provides superior weather protection. While more expensive than regular asphalt, this roofing compound is less expensive than others.
TPO (thermoplastic olefin) roofing is a popular choice for commercial buildings because of it’s relatively low cost and energy efficiency. It’s a single application compound consisting of three layers, is easy to install and costs less than other commercial roofing materials. TPO is more common in states with warmer temperatures because of its cooling properties. Color choices are limited to white, light grey and tan but lower A/C bills may outweigh the lack of design options.
EPDM is a synthetic rubber roofing membrane made of ethylene and propylene and is a popular choice for commercial buildings across the country. It is primarily used on flat roofs. EPDM is the least expensive roofing material for commercial buildings because it’s lightweight and easy to install. Other advantages include puncture-resistance, fire-resistance and the ability to withstand extreme temperatures and exposure to strong winds and hail.
Asphalt shingles are frequently used for commercial buildings for many of the same reasons as for homes. They are lightweight, durable, inexpensive and have a long lifespan. Asphalt shingle properties have evolved over the years and are now more energy-efficient, wind-resistant and available in a wider selection of colors. They are also now more environmentally-friendly and made of recycled materials; important considerations for businesses that want to reduce their carbon footprint.
