In gravel ballasted roofing systems the waterproofing membrane is covered and ballasted against wind uplift and other exposures with a layer of gravel.

Rock ballast roof.

A complete line of custom prefabricated accessories is available for the designer series membranes. A1 grit ballast is a natural smooth water worn and screened large gravel used for many applications. Stone ballast is no longer allowed by many building codes. The shingle ply membrane is printed with a shingle design in sandstone tan or slate gray.

Stone ballast typically requires crushed graded stone placed over a stone filter sheet rolled out over the insulation. Needed at perimeters and at large penetrations. Request a sample for the most accurate color representation. Contact hydrotech for specific installation guidelines.

The rock ply membrane is printed with the appearance of a ballast roof. The ballast is used to keep the roofing system cool and of out of the sun s harmful rays thus keeping energy costs down. Our roofing ballast is commonly installed over membrane and single ply systems at 1000 1500 pounds per square. The gravel top coat is also extremely resilient to heavy foot traffic and high wind scenarios.

Gravel in form of round smooth river washed aggregate without broken pieces nominal 16 to 32 mm. Over time the stones move around creating bald spots where the system isn t held down at all. White ballast can range in size from 2 1 2 3 4 inches and can be made to meet various astm standards. Despite the positive qualities associated with a ballasted roof system there are some challenges.

Ballast is required with 20 lbs s f. Ballast stone can crush the underlying insulation creating weak spots in the roof membrane.

In windy areas ballast stone can actually blow off the roof creating projectiles below.

Once completed the epdm membrane is held in place using one of the following materials as ballast with a minimum weight of 50 kg m. Conventional gravel ballasted roofs have been built for many years and are suitable on most flat roofs and structures. Ballast is commonly used with roofs made of tar and gravel roof alternatives including ethylene propylene diene monomer epdm polyvinyl chloride pvc and thermoplastic polyolefin tpo single ply flat roofs. A ballasted roof means that the roof membrane is not anchored or adhered in any way to the decking material.

In the field of the roof a minimum of 10 lbs s f.
