Denver Roofers Share the Pros and Cons of Built-Up Roofing for Businesses


April 18, 2018

Commercial roofs often differ from residential roofing systems. Not only do they often have to protect larger structures, but they must satisfy different building codes and safety regulations when installed. If you’re considering upgrading your existing roof system or are building a new office space, choosing the right replacement material can be a real challenge. Many Colorado businesses have seen great success with the Built-Up Roofing (BUR) system. Your trusted Denver roof repair team explains a few of the pros and cons of incorporating this type of roofing material into your building plans.

The Pros

  • Waterproofing: Built-up roofing offers superior waterproofing for flat and low-slope roof systems. This makes it ideal for businesses worried about excessive snowfall and ice melt. You’ll see fewer roof leaks even through the heavy winter storms Colorado is so well-known for. The system relies on multiple layers of material, protecting the attic space, insulation, and your structure from water damage.
  • Easy to Repair: As a business owner, you don’t have time to spend worrying about roof repairs or shutting your doors while a roofer is fixing an issue. BUR systems are easy to repair, reducing your downtime and your repair budget. The less time a repair takes, the less you’ll spend on labor costs!
  • Incredibly Durable: Your roof sees more foot traffic than you might think, especially if your HVAC system and condenser units are installed above ground level. BUR systems are built to withstand heavy foot traffic, allowing you to periodically inspect the condition of the roof without worrying about damaging the protective materials. In fact, with regular care and maintenance, your built-up roofing will last up to 20 years.
  • In Use for Nearly a Century: BUR systems have been in use for years, making materials readily available and increasing the number of technicians that are familiar with how to repair and maintain your roof.

The Cons

  • Installation Takes Time: BUR systems are so durable in part because they use multiple layers of materials. Each must be properly installed and prepped for the next layer before work can continue. However, once installed, the materials will last for a long time.
  • Potential for Water Damage: Unless properly installed and maintained, the roof may start to sag in places, creating low spots. Water can and will collect in these areas, slowly soaking through the materials and into the sub-roofing. Over time, the water damage may become severe enough to cause leaks inside your building. If this happens, you may need to file a claim with your business insurance provider.
  • Materials are Heavier than Other Options: Built-up roofing systems utilize tar, gravel, asphalt, and protective sheeting. All these materials can place a lot of strain on your existing support structure. If you’re replacing an existing roof system with BUR materials, you’ll want to make sure the structure can support the added weight. Otherwise, you risk severe structural damage.
