Ballast removal and re-ballast, or “swap-out” as some call it allow you to save on the cost of purchasing new ballast for your repair or re-roof jobs.

This process begins with vacuuming all 1” to 2.5” river rock from single-ply roof systems. The roofing contractor will have an area onsite to stockpile the vacuumed gravel  to be used in the re-ballasting process.

Once the new membrane is installed, the reballast can begin. Using the rock removed and stockpiled onsite, the rock will be evenly distributed at the specified amount over the contracted work area.  The roofing contractor should consider the weight of the ballast with the old roof system to determine how much, if any, ballast they will need to purchase to meet the required 10 lbs per square standard, or to account for any modifications that may be required. Purchase and delivery of the new ballast to the jobsite is managed by the roofing contractor.
