Ballasted Roof Repair
Another common commercial and industrial roofing system is a ballasted roof. The most common assembly is a loose-laid EPDM membrane over a rigid insulation board. Then, stones or gravel (ballast) are placed on top of the EPDM to hold it in place, without any fastening or adhesion. The weight of the rocks can vary from 10 pounds per square foot to 25 pounds or more. Typically, the edges of the roof and areas around penetrations will be the first sections to deteriorate, allowing water to enter. A ballasted roof repair will be necessary to eliminate all water intrusions, which can be done by moving or removing the ballast.
Ballasted roof systems are not fluid-applied like seamless roofing systems so they cannot be custom installed and tailored to meet the particular issues of each individual roof – like flashings, vents, HVAC units, etc. While a ballast roof system may sometimes have a lower initial cost compared to EPDM, TPO or PVC because there is no fastening or adhesion, their useful life is much shorter. A ballasted roof repair is recommended around penetrations and the edges of the building to stop leaks but that will only result in a short-term fix. A total removal of the ballast, replaced by a seamless roofing system will greatly increase the strength and durability of your roof.
