Maximum Asset Protection. Minimal Interruption.
Multi-Layer Defense. Commercial Grade Reliability.
The Original Black Roof.
Proven, Redundant Protection.
That need for a highly durable, fire-resistant system that can withstand heavy rooftop traffic and extreme weather for many decades. That foundational waterproofing system trusted by commercial property owners for over a century.
Built-Up Roofing (BUR) is the oldest and most reliable low-slope roofing method, constructed using multiple alternating layers (plies) of felts and hot-applied asphalt (bitumen). This overlapping, redundant layering creates an extremely thick, seamless, and robust waterproofing barrier topped with a gravel or granule surface. BUR is renowned for its exceptional fire rating and structural resilience, making it a sound choice for maximizing asset protection in demanding commercial environments.
At Achilles Roofing & Exteriors, we are experts in the complex, specialized installation of Commercial Built-Up Roofing. We ensure meticulous application of each ply, precise handling of the hot asphalt, and proper surfacing to guarantee the system delivers its maximum potential lifespan and maintains its integrity over time.

System Options We Provide
Quality Materials for Long-Lasting Commercial Systems.
Hot-applied asphalt that fuses the layers together, creating a monolithic, watertight, and self-healing seal.
Layered mats (fiberglass or organic) saturated with bitumen, providing the system's strength and stability. Typically installed in 3, 4, or 5 plies.
A thick, final layer of asphalt applied over the topmost felt layer, ready to receive the protective surfacing.
A layer of gravel, slag, or stone embedded in the flood coat to protect the bitumen layers from UV radiation and minor impact.
A granule-surfaced sheet sometimes used in place of aggregate, offering a cleaner, reflective finish and enhanced UV protection.
Essential membrane installed directly over the deck to prevent moisture from the building interior from entering the insulation and BUR system.
Our Proven Installation Process
Flawless Execution,
Step-by-Step.
Comprehensive evaluation of the roof deck and structure to ensure it can handle the load of the BUR system. Finalizing material staging and site safety plans.
Preparing the substrate (decking or insulation) and meticulously installing a vapor retarder/barrier to protect the system from internal moisture migration.
Applying the specified number of reinforcement felts and hot bitumen in alternating, overlapping layers to create a redundant, watertight seal.
Applying the final flood coat of hot asphalt and embedding the protective aggregate or granules to shield the system from UV light and weather exposure.
Thorough inspection of seams, flashing, and saturation. Final site cleanup and issuance of the 5-year workmanship warranty documentation.

Great price · $2,000–4,000
To cool down my attic, I decided to install a solar attic fan. I got proposals from four different vendors and evaluated them based on customer service, experience, implementation, and price. Achilles Roofing & Exteriors, led by Ahmad Faiz, was the standout choice.

(BUR) FAQs
How long will a BUR system last?
With proper installation and routine maintenance, BUR systems are known to perform reliably for many decades, providing long-term asset protection. Call us for a free system assessment.
Is BUR a fire hazard due to the hot asphalt?
No. Once installed, BUR systems have excellent fire ratings (Class A) due to the gravel surfacing and the inert nature of the components, ensuring enhanced safety. Ask us about our fire-rated systems.
Is BUR installation disruptive to my business?
We minimize disruption by meticulously staging materials and coordinating our crew. Our goal is to ensure the roof is protected and operations continue with minimal interruption. Contact us to discuss your project timeline.
What happens if the aggregate surfacing wears off?
The aggregate protects the waterproofing asphalt layers from damaging UV rays. We can provide cost-effective restoration services to re-apply surfacing and extend the roof’s reliable life. We offer annual maintenance plans.
Is this system heavy? Do I need a structural check?
Yes, BUR is one of the heaviest systems. We always perform a structural feasibility check to ensure the deck can safely support the multi-ply layers and aggregate. We provide a free structural consultation.
