Live Roofing

Alliance Roofing is environmentally friendly and provides the greenest type of live roofing. The owners grew up on a farm and understand the benefits that a live roof provides to people who live in an urban environment. Our system is proven and our plants, which are selected, developed, and tested specifically for rooftop cultivation, are remarkably effective.

Green roofs last longer than conventional roofs, reduce energy costs with natural insulation, create peaceful retreats for people and animals, and absorb storm water, potentially lessening the need for complex and expensive drainage systems. On a wider scale, green roofs improve air quality and help reduce the Urban Heat Island Effect, a condition in which city and suburban developments absorb and trap heat. Anyone who has walked across a scalding parking lot on a hot, summer day has felt one effect of an Urban Heat Island.

In the meantime, long-term economic benefits already outweigh the start-up costs. Because green roofs protect the roof membrane from harsh weather and ultraviolet (UV) radiation, they can last twice as long traditional roofs. Green roofs also have a fairly stable surface temperature, remaining at air temperature or cooler while traditional rooftops can soar up to 90º F (32º C) above air temperature [Source: EPA]. The extra growing medium and vegetation insulates the building from intense temperatures and minimizes heat gain. According to a Canadian study, even a six-inch extensive green roof can reduce summer energy demands by 75 percent.

There are several benefits for live roofs.

  • Plants and soil provide the roof with a natural protective shield from the elements.
  • Depending on the location, some cities also provide tax credits for more extensive urban development projects.
  • The evapotranspirative effect of the plants and four inches of growing medium typically reduces indoor temperatures 6 to 8 degrees during warm/hot weather and can reduce air-conditioning costs 25 to 50 percent in single story buildings.  This not only allows for ongoing cost savings but an initial reduction in the size of the required air conditioning equipment.
