Understanding the Differences Between BUR and EPDM Roofs

Built-up roofs, or BUR roofs, and EDPM roof, or rubber membrane roofs, are quickly becoming the standards for flat roof installations. While each roof has its merit, the style of roof that you decide on for your home will depend on which option offers the most benefit for your property.


In terms of maintenance, a BUR roofing system will require more maintenance over its lifespan. A rubber membrane system, however, is a low maintenance option that is easy to repair should you have to.


Another benefit of choosing an EDPM roof is that it weighs significantly less than BURs. By definition, a BUR system requires the building up of several layers, which adds a significant amount of weight onto your roofing joists.


When it comes to the overall cost of the roofing systems, a BUR roof is less expensive than a rubber membrane. However, you need also to consider the maintenance of the roofing system you choose and how that will impact the final roofing budget. For example, a rubber membrane is resistant to blemishes, scuffs and tears, meaning that your roof will continue to perform for the life of the materials. However, the BUR roof will likely require upkeep throughout its life, making both roofing systems cost-effective solutions.

Energy Efficiency

Unfortunately, while a rubber membrane is a significant upgrade to most traditional flat roofing materials, it is not that energy-efficient on its own. BUR systems, on the other hand, save homeowners a considerable amount of money annually. To make a rubber membrane system more efficient, homeowners may choose to use a lighter top layer, but this comes at an increased cost.

EDPM roof offer many significant benefits to homeowners over BUR systems. However, when it comes to energy efficiency, BUR wins hands down. If you are trying to figure out the best option for your flat roof, then contact a local roofing company to get your questions answered.
