Green roof research at the University of Guelph
A green roof is one with a growing substrate (i.e. artificial "soil") and topped with a layer of vegetation.
The roof top experiences extreme weather conditions (hot summer and cold winter); therefore, to ensure a successful
and sustainable green roof it needs specially-designed growing substrates, drought and extreme temperature-tolerant
plant species and species combinations, and sustainable maintenance technologies. Due to the rapidly increasing
number of green roof installations in both Canada and throughout North America, there is an increased demand for
quality green roof plants, growing substrates and production systems. Guelph Green Roof Research was initiated to
support the needs, especially in the biological aspects, of the rapidly-developing green roof industry in northern
