Built-Up Roofing (BUR) Membrane Systems
Built-up roofing, often referred to as a BUR roof, is one of the most dependable multi-ply waterproofing systems available for low-slope or flat commercial properties across Georgia, Alabama, and Tennessee. By layering asphalt bitumen with reinforced fabric sheets, these systems form a heavy-duty, seamless barrier against standing water and severe climate conditions. Because of its traditional gravel topcoat, this style is frequently called a tar and gravel roof. Today’s modern commercial applications can lower total roof weight while improving solar reflectance.
We help property managers select, install, and maintain commercial systems that protect their bottom line and hold a 4.9-star rating. Let our trusted team handle every phase of installation with minimal disruption to your daily operations.
Benefits of Built-Up Roof (BUR) Membrane for Commercial Properties
Redundant Waterproofing Defense
Unlike single-ply membranes that rely on a single layer of protection, built-up roofing features three, four, or more overlapping waterproof plies. If severe storm debris damages the top layer, the lower plies keep water from reaching your building interior, preventing costly tenant claims and facility downtime.
Outstanding Resistance to Rooftop Traffic
Heavy-duty puncture resistance allows built-up systems to easily handle frequent rooftop HVAC and routine equipment servicing.
Superior Sun and Storm Defense
Southern summers subject commercial roofs to relentless UV radiation and sudden hailstorms. The aggregate or cap sheet top layer shields the inner waterproofing plies from UV oxidation and absorbs the impact of hail, preventing early material degradation.
If a severe storm recently hit your area, our commercial team can conduct a comprehensive assessment and manage your claim directly with your insurance provider. Learn more about commercial storm damage restoration services from the Perimeter Roofing team.
What to Consider Before Choosing Built-Up Roofing (BUR)
Structural Weight
Built-up systems are heavier than single-ply TPO or PVC options. Before installation, our structural specialists should verify that your roof deck and framing can safely support the additional weight of a multi-ply gravel roof.
Extended Installation Timelines
Because each layer is applied sequentially on-site, built-up installations take longer than single-ply sheet rollouts. Our crew coordinates project schedules around your business hours to minimize noise and parking lot disruptions for your tenants and staff.
Complex Leak Tracing
While leaks are rare in a properly maintained system, water can travel horizontally between the plies before dripping into the building. Our team uses infrared moisture surveys during routine maintenance visits to pinpoint hidden leaks without disturbing the entire roof deck.
What Does Built-Up Roofing Cost?
In 2025 and 2026, the average cost for a commercial BUR installation can range from $5.50 to more than $10.00 per square foot. Key factors affecting your total investment include:
- Overall roof square footage and building height
- The number of fabric plies
- Top layer selection
- Tear-off and disposal requirements for your existing roof assembly
- Insulation R-value upgrades required by local energy codes
- Custom flashing around rooftop HVAC units, drains, and parapet walls
Accurate pricing requires a boots-on-site structural evaluation to provide clear, itemized proposals so you have every detail to make a sound decision. We also offer flexible financing solutions to help property owners manage major capital improvements. Learn more about our Financing & Payment Plans.
When Is Roof Replacement Better Than Repair?
When repair costs exceed the long-term value of the roof, choosing a replacement protects your property value and eliminates recurring repair bills.
