2. Enhanced Thermal Performance. Another significant advantage of gravel ballast roofs is their ability to improve thermal performance. The layer of gravel acts as an insulation barrier, helping to reduce heat transfer between the roof and the building below. This can result in improved energy efficiency, reduced heating and cooling costs, and ...
Roof ballast is a layer of material added to a roof for weight and stability. It helps distribute weight evenly, reducing stress on the structure. Roof ballast acts as a thermal insulator, reducing energy consumption. Material choice depends on factors such as budget, climate, and desired aesthetics. Definition of Roof Ballast
Flat roofs are commonly protected with single-ply membrane systems that are great for years of leak-proof protection. These single-ply roof membranes for flat roofs are seamless and resistant to water, hail, snow, and wind. Sometimes, though, these commercial roof systems are installed using ballast to weigh them down instead of fully adhering ...

A single ply ballasted roof is a roof that is created using the durable, flexible and resilient single ply roofing membrane. This is fully sealed and is waterproof. On a ballasted roof, these membranes are held in place with a good amount of ballast to prevent any movement. As a result, the single ply membranes are not adhered or anchored ...
Roofing ballast gravel is an ideal solution for weighing down the roofing material of single-lay flat roofs. It can also shield the roof from harmful UV rays and prevent cracking. Ozinga's roofing ballast is produced to meet ASTM standards often required by architects, engineers, and insurance companies. View all gravel types.

Ballasted roofs are loose-laid; this means the contractor can assemble all the components, including the roofing membrane and insulation, without fastening them …
The following roof covering specifications are deemed to satisfy performance requirements without the need for testing. • Loose laid gravel at least 50mm thick, or with a mass greater than 80 kg/m² (subject to maximum and minimum aggregate sizes). • Cast stone or mineral slabs at least 40mm thick. • A sand cement screed at least 30mm thick.
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 ...
In gravel ballasted roofing systems, the waterproofing membrane is covered and ballasted against wind uplift and other exposures with a layer of gravel. Conventional gravel ballasted roofs have been built for many years and are suitable on most flat roofs and structures. ... Be the first to review "Roof Ballast 1-1.5″" Cancel reply. Your ...
It can perform well in high winds if it is adequately embedded into the asphalt matrix, or is on a roof with a high parapet.
