Built-Up Roofing
The First Choice
In Quality
And Long Term Value

While there are many choices in commercial roofing to offer the right choice for your individual needs, it would be an injustice if we failed to provide perspective on the choice of Built-Up Roofing (BUR) which is the industry benchmark for commercial roofing.

BUR VS. SINGLE-PLY

Which is better, BUR or Single-Ply? When it comes to low-slope roofs, BUR is by far the best choice. BUR offers superior quality, lasting value and benefits;

BUR

Multiple layers and glass fiber reinforcement to prevent leaks

Multiple layers of hot waterproofing asphalt

Difficult to puncture

Sealed over entire roof area without fasteners

Limits movement with high tensile strength

Easily repaired

Holds up better in high traffic areas

SINGLE-PLY

Only one single layer to prevent leaks, much of which is not reinforced

No asphalt

Vulnerable to tears and penetration

Often laid loose, requiring fasteners

Limits movement with elongation

Difficult or more costly to repair

Not designed for high traffic areas

A Proven Track Record

Over the years, Built-Up Roofing has earned a great reputation with building owners, architects, engineers, roofing product manufacturers and roofing contractors. They all know Built-Up Roofing is a proven winner.

Invest in a Roof That Will Last

The cost of a Built-Up Roofing system is minimal when compared to the cost of potential damage from a poorly installed single-ply roof. Major companies across the country have come to understand that the roof above is critical to protecting the business below.

THE BENEFITS OF BUILT-UP ROOFING

LONGER SYSTEM LIFE

Each ply of a Built-Up Roofing system contains a mat of glass fiber reinforcement - most single-ply systems contain no reinforcement at all. When multiple plies are combined and sandwiched between layers of water-resistant asphalt, the result is a longer lasting roof.

LIMITED ROOF MOVEMENT

All roofs expand and contract. Single-ply roofs respond with elongation. But over time these systems can lose their elasticity, resulting in buckling, ridges and splits. A Built-Up Roof, however, limits movement with a high tensile strength in excess of the recommended 200 lbs./sq.in. The potential for fracturing is more or less eliminated, and the Built-Up Roof will last longer.

SUPERIOR WATER RESISTANCE

Multiple layers of reinforcement offer multiple opportunities to prevent leaks. Single-ply membranes only offer one chance at preventing a leak. Plus, there's nothing quite like asphalt when it comes to making a roof resist water. Asphalt is the glue that holds a Built-Up Roof together. It also seals and protects the entire roof, delivering up to five times greater water-resistant thickness.

EASIER INSTALLATION

On a hot Built-Up Roof, the multiple plies are fused together using hot-mopped asphalt to create a monolithic barrier. Every inch is firmly and completely adhered over the entire roof area, without the need for ballast or fasteners. Single-ply systems require ballast or fasteners because they are generally laid loose. But ballast (such as stones) increases structural load and can be blown off by strong winds. And fasteners create less stress points and additional opportunities for moisture leakage.
