When it comes to safeguarding your commercial property, the roof is the first line of defense. At San Diego County Roofing & Solar, we understand that choosing the right roofing material is crucial for long-term durability and cost-effectiveness. This article delves into the top six types of commercial roofing materials, their unique features, and how they can benefit your business.

Metal Roofing: The Long-Lasting Choice

Metal roofing stands out for its exceptional lifespan and robustness. Available in a variety of metals—galvanized steel, aluminum, copper, and coated stainless steel—these roofs offer unparalleled durability. They are excellent at preventing water leaks and can also reflect solar rays, thereby enhancing HVAC efficiency. If you’re aiming for a sleek, modern aesthetic, metal roofing is the way to go.

Built-Up Roofing: Layered Protection

Built-Up Roofing (BUR) is the quintessential tar and gravel roof commonly seen on commercial buildings. The strength of a BUR system lies in its multiple layers, which include asphalt, tar, and cold-applied adhesives sandwiched between reinforced felt and bitumen. This layering technique offers robust protection against leaks and enhances the building’s insulation, making it a cost-effective choice for businesses.

EPDM: The Energy Saver

Ethylene Propylene Diene Terpolymer (EPDM) is renowned for its rubber membrane that shields against UV radiation. The waterproofing feature of EPDM roofs helps in reducing energy costs related to heating and cooling, making it an economical choice for businesses looking to save on utility bills.

TPO: The Versatile Option

Thermoplastic Polyolefin (TPO) is a popular choice among roofing contractors in San Diego due to its affordability and adaptability. TPO roofs can be installed over various surfaces and offer strong resistance to high winds and fire. Their ability to withstand extreme temperature fluctuations makes them an ideal choice for varying climates.

Green Roofs: The Sustainable Alternative

Green roofs are gaining traction for their multiple benefits, including solar insulation and reduced rain runoff. They also offer a pleasant space for employees to relax, contributing to an overall healthier work environment. If sustainability is a priority for your business, a green roof is worth considering.

Installation and Maintenance Tips

Metal Roofing Installation

Metal roofs require a sturdy frame anchored with bolts. The metal sheets are then secured and sealed to provide an airtight, long-lasting roof.

BUR Installation

Built-Up Roofs involve layering various materials like rubber, tar, and asphalt, which are then coated with rubberized asphalt and topped with gravel.

EPDM Installation

EPDM roofs are relatively easy to install. The material is rolled onto the frame, and seams are sealed with specialized glue to create a waterproof seal.

TPO Installation

TPO roofs require an adhesive and sealer applied to the surface area, followed by layering the commercial waterproof membrane and TPO material.

Green Roof Installation

Green roofs do not require additional structural support but do need proper drainage systems to be effective.

Routine Maintenance

  • Keep the roof clear of debris, ice, and snow.
  • Address minor leaks immediately.
  • Ensure proper drainage to prevent water pooling.
