Commercial roofing and residential roofing are not the same. Most commercial roofs are flat and asphalt shingles are inadequate. Instead, flat roofing materials like single-ply membranes are used. This video explains the most popular materials for commercial roofing.
Metal roofing is a very common roofing material for businesses. It works well for flat roofs and low slope roofs. They offer enhanced energy efficiency and durability. They also boast one of the longest lifespans for all roofing materials, lasting up to 50 years.
The next is EPDM roofs. This is a rubberized material that became very popular for businesses in the 80s and 90s. It’s a time-tested material that can be multiple layers thick for better protection.
Thermoplastics are another popular single-ply roofing option. There are two types: TPO and PVC. They’re both good options and offer great resistance against the expansion and contraction from fluctuating temperatures that will damage other roofs. Both materials are white and reflect UV rays, making them very energy efficient. Their seams are also much stronger which will prevent leaks and the need for repairs or replacements.
