Eco-Friendly vegetative roofing repair and installation in Milwaukee


Green roofing is a 21st-century take on the sod-covered roofs used in Scandinavian home construction 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.

What is green roofing?Green roof systems in Milwaukee

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 stormwater runoff.

Subsidies for green roofing systems in Milwaukee

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.

Green roof system benefits

  • Can be used for recreational space or gardening
  • Reduces carbon dioxide in urban environments
Green roofing types

There are three main types of green roofing to choose from: extensive, semi-intensive, and intensive. Each type has its strengths and weaknesses, and not all types of green roofing can be installed on any roof. Green roofing has exploded in popularity over the last decade or so. Green Roofs for Healthy Cities (a Toronto-based organization) estimates a 15% increase in green roofs in North America since 2013, and that number is only likely to grow. Alois Roofing is proud to help commercial businesses and residences throughout southeast Wisconsin join the green roofing revolution.
