Restore Your Built-Up Roof with Silicone Coating

A Smarter Alternative to Tear-Off & Replacement

When a built-up roof starts failing, the default response from many roofers is full tear-off and replacement; an expensive, disruptive process that doesn't have to be your only option. At Seamless Roofing, we specialize in silicone roof coating systems that restore built-up roofing to a watertight, energy-efficient condition at a fraction of the cost and without shutting down your operations. Commercial property owners nationwide trust our team to protect their existing roofs.

Built-Up Roofing & Its Common Problems

Built-up roofing, commonly called BUR, is one of the most widely used commercial roofing systems in North America. It consists of multiple alternating layers of reinforcing fabric and bitumen (asphalt or coal tar), topped with a surface layer of aggregate, gravel, or a cap sheet. This layered construction gives BUR its strength and longevity, and many buildings still rely on BUR systems that were installed decades ago.

BUR systems are known for their durability, redundancy, and fire resistance. However, like any roofing system, they age. 

And when they do, the problems they develop can be serious:

• Ponding water: Low spots trap water that sits for days after rain, accelerating deterioration and eventually penetrating the layers below.
• Blistering & delamination: Moisture trapped between layers creates blisters that expand, separate, and rupture, leaving the roof vulnerable to leaks.
• Alligatoring & surface cracking: Prolonged UV exposure causes the bitumen surface to oxidize and crack, losing its waterproofing integrity.
• Flashing failures: Edge flashings, penetrations, and transitions are common failure points where water finds its way in.
• Gravel displacement: Wind and foot traffic shift or remove the gravel ballast, leaving sections of the bitumen membrane exposed and unprotected.

Shortcomings of Traditional Repairs & Replacements

Spot repairs on a BUR system can patch visible problems, but they rarely address the root cause, and the underlying structure continues to deteriorate. Each repair buys time without adding long-term protection. Meanwhile, costs accumulate, leaks recur, and the disruption to your tenants or operations never quite stops.

Full roof replacement is even more involved. Tearing off layers of gravel, bitumen, and substrate generates significant waste, requires extended crew access, and often means temporary disruption to rooftop equipment, drainage systems, and building operations. When the underlying deck is still structurally sound, replacement may be the more costly and time-intensive path without being the better one.

Silicone Roof Coating: The Smarter Solution for BUR Systems

Silicone roof coating offers commercial property owners a way to restore their built-up roof without the expense and disruption of tear-off. Seamless Roofing applies a seamless, flexible silicone membrane directly over the existing BUR system, sealing cracks, encapsulating deteriorated surfaces, and creating a fully waterproof barrier that stands up to ponding water, UV radiation, and thermal movement.

Why Silicone Works So Well on Built-Up Roofing

Seamless Waterproof Coverage

Silicone coating is applied as a fluid that self-levels across the roof surface, filling in surface irregularities and creating a continuous membrane with no seams, eliminating the gaps where water typically infiltrates BUR systems.

Exceptional Ponding Water Resistance

Unlike many coatings that break down when submerged, silicone is specifically engineered to resist standing water indefinitely. For BUR systems prone to low spots and drainage issues, this is a critical advantage.

Superior UV Stability

Silicone doesn't oxidize or become brittle from sun exposure the way bitumen does. It maintains its flexibility through years of temperature cycling, which is especially valuable for BUR systems in climates with wide seasonal temperature swings.

Energy Efficiency

The highly reflective surface of the silicone coating bounces solar energy away from the building rather than absorbing it. Property managers across hot-climate markets like Texas and Georgia see measurable reductions in cooling loads, which is a direct operational benefit alongside the waterproofing performance.

No Tear-Off Required

When the existing BUR substrate is structurally sound, the silicone coating goes directly over it. No demo crews, landfill disposal costs, or extended timeline. The building stays operational, and the project moves faster from start to finish.
