Ballasted roofs are durable and long lasting. The roof tends to flex a little better under the expansion and contraction of heat and cold, making it a bit more durable. Stones or concrete pavers protect the waterproofing layer from UV rays, hail, and foot traffic.

It's fire resistance (ballast roofing offers Class-A fire resistance without the need for gypsum underlayments or expensive fire-retardant chemicals), sustainability, and ease of repair (since the ballast stones aren't actually embedded in the membrane, they can be easily removed and the membrane repaired as necessary), and overall energy efficiency make ballast roofing systems a popular

A ballasted roof uses larger and heavier stone, compared to a built-up roof, and is laid over the roof membrane. The stone, gravel, or rocks are used as a weighted barrier for the materials below. The weight of the gravel or stone is helpful for distribution purposes. In a scenario where there is more equipment on one side of the building than the other, a roofer might increase the amount of

Design of Loose-Laid Gravel Stone Ballasted Roofs Roofing membranes have the potential for "wind uplift" if they are exposed to high pressure differentials above and below the membrane. Forces which create pressure differentials are suction from above, as wind sweeps across the roof, and high interior building pressures from underneath. For unadhered, loose-laid roofing membranes, ballast is

A "ballasted roof" generally refers to a single ply roof membrane that is held in place against wind uplift by loading the surface with either stone ballast or pavers. The membrane for such systems is usually not attached to the substrate, although some systems do have supplementary perimeter attachment. Since the ballast is the primary resistance to wind uplift, there has to be a lot of

Gravel ballasted roofs with Sikaplan® or Sarnafil® single ply membranes are conventionally installed. The single ply membrane and other roof components, including thermal insulation, are loose laid. The buildup is ballasted with a gravel layer of at least 50 mm and 80 kg/m 2. The gravel ballast secures the roof waterproofing against wind uplift forces. Sika's Experts Provide Assistance to
