BUR Industrial Roof Systems
Traditional built-up roof (BUR) systems have been around the longest and due to their proven, time-tested performance, are the best choice for industrial building owners. Their simplicity also makes them very inexpensive. BURs typically consist of several layers of hot tar with gravel as the top layer. The redundancy of layers provides added strength against the elements and foot traffic. Modern BURs can be hot-mopped or cold-applied and gravel-surfaced or smooth-coated, to create the most durable, water-resistant surface.
Modified Bitumen Industrial Roof Systems
Modified bitumen roof systems are similar to BUR systems, but are rolled onto the roof surface in sheets with additional polymers for added protection and extended lifespan. The material is heated with a blowtorch during installation, which creates a good seal. Due to the fire danger involved, these systems should only be installed by industrial roofing companies with vast experience like McDonald & Wetle. Modified bitumen doesn’t withstand foot traffic as well as traditional BUR systems, but it’s one of the more environmentally friendly flat industrial roof options. Due to its reflective nature, it helps reduce energy costs by keeping your building cooler.
Single-Ply Industrial Roof Systems
There are several types of single-ply roof systems, but the three most common are EPDM (Ethylene Propylene Diene Monomer), PVC (Poly Vinyl Chloride) and TPO (Thermoplastic Polyolefin). All three are durable, long-lasting and cost-effective options. While each system is similar, each offers unique properties in different conditions. We can help determine which one best suits your specific needs, budget and performance requirements.
