What is Overburden?
Overburden is anything placed on a roof that was not part of the original roof assembly. Whether the roof is brand new or decades old, added items are considered overburden and must be approved by the manufacturer to avoid impacting or voiding the warranty.
Common examples include roofing solar systems, vegetative roofs, HVAC units, plumbing, and plaza decks. Each must meet manufacturer criteria to maintain warranty coverage.
The U-Anchor has been thoroughly evaluated by North American roofing manufacturers and is widely recognized as the leading rooftop equipment attachment solution. When selecting attachment methods, always request proof of warranty inclusion. Documentation for the U-Anchor is provided below.
