Choosing the right commercial roofing system for your facility involves taking many factors into consideration, especially if you’re looking into upgrading an existing roof. In today’s post, your local roofing contractor Pruden Roofing shares a guide to choosing the right roofing system for your commercial facility.
What Kind of Commercial Facility Do You Have?
You have to choose the roofing system that’s appropriate for the building’s purpose. For example, facilities like office spaces require many HVAC systems, which means much of the rooftop’s area will be dedicated to vents and HVAC condenser units. On the other hand, a large warehouse or hangar may not have such requirements. Some roofs may need a hard-wearing outer layer as protection against foot traffic from people other than roofers and maintenance staff. Others still may require waterproofing, or a reflective layer to reduce radiant heat absorption. As a commercial property owner or manager, you will need all of these to make informed decisions when it’s time to choose a roof.
What Are the Types of Roofing Systems?
Roofing companies offer various materials, configurations and brands. To keep things simple, you only need to remember two types of commercial roofing systems:
Built-up roofing. As the name implies, built-up roofs (BURs) are built up from multiple layers of roofing material. You’re probably already familiar with traditional flat roofs built using layers of tar and reinforcing material like fiber, then topped with a layer of gravel or stone. These roofs are impervious to punctures and foot traffic and absorb less radiant heat. A modified bitumen roof is a similar system that features a top layer of material similar to asphalt shingles. Being made of multiple layers, BURs have longer installation times.
Single-ply roofing. Single-ply roofs consist of a layer of thin material (PVC, TPO, or EPDM) that covers a substrate. Sheets of the material are typically welded or fastened to create a blanket-like cover. Single-ply roofs can withstand most weather conditions but are vulnerable to punctures. Ponding water can also result in damaged seams. You can choose to have the outer layer loosely laid and weighed down by ballast, fastened at the seams, or fully adhered to the substrate using heat or adhesive. Most types of single-ply roofing systems have a light-colored outer surface that helps reduce the heat absorbed through the roof.
