The best vegetative roofing repair and installation in southeast Wisconsin
Green roofing is a 21st century take on the sod covered roofs used in Scandinavian home construction in in the 1700s. Today, green roofing encompasses everything from rooftop container gardens to an entire roof surface covered in vegetation. Green roofs can also be roofs with energy saving technologies like solar panels and reflective materials.
A true “green roof” is a living, growing carpet of vegetation. These roofs are built with a layer of dirt over a waterproof membrane. The vegetation is usually drought resistant grass, wildflowers or landscaping plants. Irrigation systems are often incorporated into the installation. Besides adding visual appeal, a green roof can significantly decrease energy costs and reduce storm water runoff.
In addition to earning LEED credits for Storm Water Design and Heat Island Effect, there are also financial incentives for green roofing. In Milwaukee, for instance, the Milwaukee Metropolitan Sewerage District (MMSD) offers a $5 per square foot subsidy for green roofing. Reflective heat-reducing roofs using Energy Star approved materials (not vegetation) are also eligible for a tax credit of up to $1,500 (on the cost of materials).
How long does a green roof last?
Depending on the level of maintenance needed and the attention given to this maintenance, a green roof can easily last 30 to 50 years or more. There are sod roof buildings in Europe that have endured for centuries.
