Built-Up Roofing by GSM Roofing: Time-Tested and Durable

When Fred Gooding started his roofing business in 1946, there was only one choice for low-slope roofs: the built-up roofing (BUR) system. Today, BURs can be cold-applied or hot-mopped, smooth-coated or gravel-surfaced, modified or traditional bitumen.

Our commercial roofing experts are ready to partner with you to install this durable and time-tested roofing system.

What to Expect When You Choose Built-Up Roofing for Your Commercial Structure

Once called asphalt roofs, the construction of built-up roofs involves a layering process using bitumen (made from asphalt, coal tar, or cold adhesive) and reinforced fabric. Roofers have used these versatile membrane systems for decades on low-slope and flat roofs.

The first applied layer is the bitumen. It’s then topped with fabric, felt, or fiberglass from a roll. These layers are repeated based on the project. The completed roof often has a surface aggregate (for aesthetics and longevity) and an optional reflective coating (for energy savings).

The Built-Up Roof System’s Best Features, and a Few Challenges

The best feature of a built-up roofing system is redundancy. This roof type is “built up” with several layers—each one offering protection if the layer above it becomes damaged. Although built-up roof membranes aren’t as popular today as they once were, they still provide a viable option for new construction and roof replacements.

As we mentioned earlier, this system for flat roofs was more popular in the 1970s, but it’s still around today because it’s rugged, dependable, and long-lasting. This commercial roof is water-resistant, protectant against UV rays, fire-resistant, resilient against wind and rain, and low-maintenance (requiring only one to two annual inspections).

A built-up roof might be the best option if your operation cannot tolerate a roof leak. That includes food manufacturers, museums, and buildings containing high-value items.
