2025年1月17日 · Discover the key features, benefits, and maintenance tips for a ballasted roof system. Learn how this durable roofing solution compares to EPDM and TPO roofing for commercial and residential applications.

An Oak Ridge National Laboratory study showed that ballasted roof systems performed equivalent to or better than traditional cool roof membranes, according to Architect Magazine. However, the roof's slope, height, and structural deck can be the limiting factor for ballasted roofs.

A ballasted EPDM roof is a type of roofing system where a layer of gravel or another heavy material weighs down the EPDM roof membrane, providing a sturdy and weather-resistant shield for commercial and industrial buildings.

Popular for large-scale retail stores and warehouses, ballasted systems feature a loose-laid membrane held in place by stone or pavers. The ballast helps to shield the membrane from inclement weather and extend the life of the roof.

2024年4月8日 · A ballasted roof system is a type of flat or low-sloped roofing system that relies on the weight of ballast materials, such as gravel or pavers, to hold the roofing membrane in place. These materials provide stability and protection against wind uplift and UV radiation.

A ballasted roof means that the roof membrane is not anchored or adhered in any way to the decking material. It is, however, ballasted, generally with gravel. When the concept first came to the U.S., plenty of roofers scratched their heads and wondered how the roof stayed on without being anchored, especially during high winds or storms.

2023年9月1日 · A ballasted roof is a system in which the waterproofing membrane is loose laid over the roof deck and held in place by a layer of ballast, usually stones, gravel (sometimes called aggregate), or concrete pavers.

A mechanically-fastened roof is stronger and more secure than a ballasted roof system, particularly at roof penetrations and the roof perimeter. A mechanically-fastened roof is lightweight, resulting in reduced sizing and cost of the structural roof system.

Installed over loose laid FiberTite membrane, ballast roof systems reduce membrane exposure to UV rays and increase fire resistance. The use of ballast is the original method of waterproofing and utilizes dirt, sod, palm leaves and other natural materials to shed water.
