Discover what commercial roofing is, how it differs from residential roofing, and what Fresno businesses need to know before starting a project.
When people think of roofing, they often picture shingles on homes—but commercial roofing is a different world altogether. From the materials used to the installation methods and maintenance, commercial roofs come with their own unique set of challenges and solutions.

TPO Roofing
Popular for its energy efficiency and heat-reflective properties, TPO is lightweight, durable, and resistant to UV rays and chemicals. A great choice for Fresno’s sunny climate.
EPDM Roofing
Made from synthetic rubber, EPDM is known for its long lifespan and flexibility. It performs well in varied temperatures and is relatively easy to repair.
PVC Roofing
Highly durable and fire-resistant, PVC roofs are also energy efficient and ideal for restaurants or buildings with rooftop grease exhausts.
Built-Up Roofing (BUR)
Often called tar and gravel roofs, BUR systems offer excellent waterproofing and UV protection. They’re heavier and more complex to install but highly effective.
Modified Bitumen
A hybrid of BUR and membrane systems, this type of roof is reinforced with fiberglass or polyester and offers good durability in various climates.
