Understanding Built-Up Roof Systems: What You Need to Know

A built up roof system is the ideal solution for commercial buildings and is surprisingly affordable compared to other roofing systems. There are many ways to build a roof, but certain styles are better for commercial buildings. For instance, built up roofing (BUR) is ideal for buildings with a low-slope or flat rooftop.

What Is a Built Up Roof System (BUR)?

A built up roof is exactly what it sounds like: a roof “built up” in layers of ply sheets and asphalt. It’s actually an evolution of the traditional asphalt roofing system. Multiple layers are an excellent way to protect your commercial roof from leaks, and some BURs are designed to reflect heat to keep your building cool.

Built Up Roof System Installation Facts

A BUR begins with a base layer built directly on top of the building’s insulation or cover board. This bottom layer protects the roof from water and provides the surface necessary for additional layers to be added.

Hot asphalt is applied to the base sheet and a layer of roofing felt is installed on top. This process is repeated several times, and each new layer creates a stronger barrier to resist water. More layers are added until the target number of layers are added to the roof. While asphalt is traditionally applied hot, there are cold application methods that can be used as well. Once the additional material is layered up, the roof is topped by a final layer consisting of asphalt and protective granules.

Benefits to a Commercial Built Up Roof

Reliability

In the United States, built up roof systems have been relied on for more than 100 years because they provide excellent protection against the elements. The BUR market is the largest of all roofing system segments in the U.S. and is valued at nearly $700 million.

Adverse-Weather-Resistant

A built up roof can withstand harsh weather more than other types of roofing. The layers are built tightly and the materials are extremely sturdy.

Waterproofing Redundancy

Since BUR roofing is made from multiple layers, this redundancy provides extra protection from water for the building.

Great Warranties

A built up roof system usually comes with a warranty for up to 20 years.

Heat-Reflective

A built up roof system can be finished with a white-coated cap sheet to reflect the heat from the sun. This will keep your commercial building cooler, reduce the strain on your HVAC system, and save you money on energy bills.

Protection Against UV Rays

While a BUR roof reflects heat, it also reflects UV rays from the sun, preventing damage.

Fire-Resistant

Nothing beats a fire-resistant roof on a commercial building. It takes intense heat to ignite the tar used in a BUR roof. Fires can be extremely destructive and costly to recover from, not to mention the potential dangers to building occupants.

Low-maintenance

BUR roofs don’t require as much maintenance as traditional roofing options, like asphalt shingles or wood shakes. Although a BUR roof may experience cracks, blistering, or split joints, the upkeep is minimal. However, annual roof maintenance is easy when you stay on top of inspections. It’s recommended to get a roof inspection at least once a year.

Affordable

Other roofing systems are expensive, but a BUR roofing system gives you protection at a lower cost.

Why You Need a Built Up Roof System for Your Commercial Building

When you own a commercial building, you’ll eventually need to make repairs to your roof. A roof will only last so long before starting to deteriorate or degrade due to adverse weather, storms, and heat from the sun. If your current roof is leaking, in a state of disrepair, old, or not performing well, it’s time to consider a new roof. However, with all your options, you might find it hard to choose the right type of roof.

A built up roof is a good choice for commercial buildings because it’s cost-effective, provides excellent waterproofing, and is easy to maintain. While no roof is immune from issues, a BUR is more affordable to maintain over time, provided you keep up with yearly inspections to catch issues as they arise. Of all the reasons to get a built up roof system, durability and extra protection are at the top of the list. When you install a BUR on your commercial building, you’re adding multiple layers of protection against the elements, water in particular.

Taking proactive steps to prevent water damage to your building is one of the best moves you can make. Water damage can be devastating to a building and can cause extensive, costly repairs.
