Given that plants are living, breathing organisms, plant warranties are typically offered by the maintenance provider not the LiveRoof grower or LiveRoof Global, LLC. By providing consistent high quality care—keeping drains clean, preventing weed infiltration, watering during extended drought and monitoring soil fertility—the maintenance provider can reduce the chance of a warranty claim. He has a vested interest in the ongoing healthy condition of the plant material.
We provide instructions and seasonal reminders for care of the LiveRoof system, and LiveRoof growers are available as an ongoing resource. But the maintenance contractor is in the best position to warrant the plants.
Any plant warranty will vary by each licensed LiveRoof® grower (independent of LiveRoof Global, LLC). Typically plant warranties from growers are associated with additional charges and the adherence to and documentation of specific maintenance practices. Contact your local licensed grower for details.
LiveRoof and Membrane Warranties
LiveRoof is compatible with most methods of rooftop waterproofing (PVC, EPDM, TPO, Mod-bit, cold fluid, inverted and conventional), and has been installed above products from nearly every roofing system manufacturer in North America (large and small). And, in all cases ( where the waterproofing manufacturer’s specifications are followed) LiveRoof is compatible, and material and workmanship warranties have remained intact.
Be advised, however, some waterproofing membrane manufacturers also offer green roof systems for sale, and sometimes may attempt to leverage an “overburden warranty” in attempt to make a sale. This type of warranty is a for-fee warranty and is not required in the vast majority of installation.
An overburden warranty has nothing to do with material or workmanship warranties—which are important, and remain intact regardless of green roof system provider. When a project does, for whatever reason, require an overburden warranty, LiveRoof can provide it as well (and brings the advantage of fast moving, local service).
There is one more type of optional warranty, a “single source warranty“, which is occasionally offered. This is similar to an overburden warranty but promoted as a “make one call” warranty. Companies that offer such warranties in conjunction with LiveRoof systems, include the following:
