Built-Up Roofing: What Columbus Business Owners Should Know

When you’re managing a commercial property in Columbus—whether it’s a retail space in Dublin or a warehouse in Grove City—your roof is your first line of defense. One of the most reliable and time-tested commercial roofing systems? Built-Up Roofing, also known as BUR.

Let’s walk through what it is, how it works, and whether it’s the right fit for your building.

What Is Built-Up Roofing (BUR)?

Built-up roofing is a layered roofing system commonly used on low-slope and flat commercial roofs. It’s made by alternating layers of:

• Bitumen (asphalt or cold-applied adhesive)

• Ply sheets (reinforced fabrics, usually fiberglass or organic felt)

• Top surfacing like gravel, slag, or a reflective coating

It’s called “built-up” because it’s literally built up in layers on-site, forming a durable membrane that’s tough to beat in terms of longevity and waterproofing.

Why Built-Up Roofing Is Still a Go-To for Commercial Buildings

BUR has been around for over a century, and for good reason. Here's why Columbus-area property owners still choose it:

1. Proven Durability

A well-installed BUR system can last 20–30+ years. That’s ideal for large roofs where repairs can get expensive.

2. Excellent Waterproofing

Multiple redundant layers mean you’re not relying on a single membrane. If one layer is damaged, others are still protecting your building.

3. Good Fire Resistance

Especially when topped with gravel or a mineral-surfaced cap sheet, BUR can offer Class A fire resistance.

4. Thermal Performance

You can add rigid insulation under the BUR layers for high R-value and improved energy efficiency.

5. UV and Impact Protection

That gravel surfacing isn’t just old-school—it protects the roof from sun damage and foot traffic.

Is Built-Up Roofing Right for Your Columbus Building?

It depends on your building’s design and your long-term goals. BUR might be a great fit if:

• You have a low-slope or flat roof

• You want a long-term investment with fewer repairs

• You need excellent waterproofing (especially if you have rooftop equipment or HVAC units)

• You want a time-tested system that can handle Ohio’s freeze-thaw cycles

That said, installation can take longer than single-ply systems like TPO or EPDM. It’s also heavier, so your roof deck needs to be structurally sound. We’ll help you assess that during the estimate.

FAQs About Built-Up Roofing

How long does a built-up roof last?
20–30 years with proper maintenance. We’ve seen some last even longer with regular inspections and repairs.

Does BUR work in cold climates like Ohio?
Yes. When properly installed with the right bitumen and insulation, BUR performs very well in freeze-thaw conditions.

Can you install BUR over an existing roof?
Sometimes. If the existing roof is dry, stable, and code-compliant, it may be possible. We’ll inspect and let you know your options.
