What is Overburden?

Overburden is material or equipment that is located above the roof assembly. While each property is unique, there are many overburden options such as vegetative roofs, blue roofs, blue-green roofs, purple roofs, and rooftop solar.

Overburden, simply put, is anything on top of a roof that was not already integrated to a finished roof. Whether the roof is one day old or 20 years old, if it was not part of the original roof assembly, it is considered overburden and must be accepted by the manufacturer prior to installation to avoid affecting or even voiding the warranty.

There are many types of overburden. From rooftop solar systems to vegetative roofs to HVAC equipment, plumbing systems and even plaza decks. Each type of overburden must meet the criteria and be accepted by the roofing manufacturer as to not nullify your roof’s warranty.
