FLAT ROOFING

Spray rubber conforms to the extremely uneven surface of gravel without splitting and creates a fully adhered, watertight membrane. When completed with a UV Thermal top coat, it becomes a highly energy-efficient roof as well.

Typical BUR roof systems are overlapping rubber membrane sheets covered with asphalt, coal tar or cold-applied adhesive to the seams. BUR’s are usually topped with rocks or gravel as well, but use a thin layer of pea gravel or crushed stone as opposed to much larger stones in a ballasted roof. This, however, inevitably leads to leaks and built-up roof repairs occurring at flashing details – anywhere the membrane has a seam or meets a non-flat surface.

Unlike BUR roofs, Austin’s fluid-applied seamless system can be custom installed and tailored to meet the particular needs of each individual roof – like flashing, vents, HVAC units and more. Surface spudding, repairs and the installation of a seamless roofing system will make your roof stronger and more durable than the day it was installed.

Gravel roofs are common, but come with challenges: damage may not always visible, leading to leaks and water intrusions that are difficult to source. By extension, when it comes time for a new roof, the expense and labour of removing and disposing off the old gravel roof can be costly.

A seamless liquid rubber roofing system is ideal for retrofitting an existing embedded gravel roof in order to avoid a costly and disruptive tear-off. In contrast to the most common gravel roof assembly that requires ballast weighing up to 25 pounds per square foot to be placed without fastening on top of a loose-laid EPDM membrane that is again above a rigid insulation board, Austin’s rubber membrane is lightweight and applied, to any thickness, in a single application using a spray and seal method. It does not require any fabric reinforcement or underlayment. And it can be applied to even the most uneven gravel surface without splitting, creating a fully adhered, watertight membrane.
