 Depending on the type, a commercial roof can last anywhere from 15 - 45 years, with metal outlasting most other commercial roofing systems. Popular Commercial Roofing Systems
Built-Up Roofing (BUR) Lifespan: 15-30 years Built-Up Roofing, commonly referred to as BUR, is composed of multiple layers of bitumen and reinforcing fabrics. BUR systems are known for their durability and ability to withstand heavy foot traffic. Modified Bitumen Roofing Lifespan: 20-25 years Modified Bitumen Roofing is similar to BUR but includes polymer-modified bitumen for enhanced elasticity and flexibility. This type of roofing is typically installed in multiple layers, offering robust resistance to weathering and temperature fluctuations. EPDM Roofing Lifespan: 20-30 years EPDM is a synthetic rubber membrane known for its durability and versatility. It is highly resistant to UV radiation and ozone, making it an excellent choice for a wide range of climates. TPO Roofing Lifespan: 15-20 years TPO roofing membranes are popular due to their energy efficiency and heat-welded seams, which provide superior waterproofing. They are also highly resistant to dirt, bacteria, and debris buildup. PVC Roofing Lifespan: 20-30 years PVC roofing is known for its high durability and resistance to chemicals, fire, and wind. It is an excellent option for roofs exposed to harsh environmental conditions or chemical contaminants. Metal Roofing Lifespan: 30-45 years Commercial metal roofing systems, often made from materials like steel, aluminum, or copper, are renowned for their longevity and durability. They can withstand extreme weather conditions and provide excellent fire resistance. 3 Common Types of Damages That Affect The Lifespan of the Roof
1. Leaks & Moisture
Water infiltration can cause significant damage to the roof structure and underlying materials. Look for signs of water stains, mold, or damp insulation. Trapped moisture can then cause blisters and bubbles on the roof surface, compromising its integrity. Sometimes improper drainage can cause standing water, which then cause the leaks. 2. Punctures & Cracks Foot traffic, falling debris, or weather impacts can cause punctures or cracks in the commercial roofing material, leading to leaks. We especially see these types of damages here in Florida during the summer hurricane months. 3. Shrinking Some commercial roofing materials may shrink over time, leading to pulling away from edges or seams, increasing the risk of leaks and damage. That's why we recommend using the highest quality coatings and sealants available, like Everprime and Silkoxy from Everest Systems.
