Green Roof What to Consider When Planning to Install One

Green Roof What to Consider When Planning to Install One, and in various times, places, and cultures, this roof was the norm. People lived in earthen homes that were sometimes dug out of hillsides or creek banks, and the native grasses and wildflowers grew naturally on top. Other homes had sod or thatched grass roofs. Modern people are discovering the merits of this kind of roofing. If you are planning to install one of these, here are some things to consider and keep in mind.

1. Types of Green Roofs

Before you begin, you need to determine what kind of this roof you want. Here are some of the various types.

* Extensive – Despite the name, extensive green roofs require less maintenance than the other two types. They are nearly self-sufficient, and require maybe an annual weeding or fertilizing. They are not as heavy as other green roofs, since they require less soil. If an extensive green roof is going to be covered with moss, a thin layer of growing medium such as rockwool is all that is necessary.

* Semi-Intensive – These roofs require more intensive maintenance – hence the name. Semi-intensive roofs require regular watering, sometimes in the form of irrigation, and regular weeding and fertilizing. They offer more variety than extensive green roofs. Shrubs, perennials, and herbs can be grown on a semi-intensive roof.

* Intensive – This high-maintenance green roofing option offers the most variety of design and flora. Garden paths, rock formations, fountains, and other elaborate additions can be a part of an intensive living roof. Large, flat-topped buildings can even have playgrounds and park-like settings as part of their eco-friendly roof.

Remember, high-maintenance is not necessarily bad. If you are the kind of person who likes to spend time in a garden – and maybe you don’t have the land to have a regular garden – then an intensive one of these roofs could be a good investment for you.

2. A Weighty Issue

Soil and sod are heavy. Before you get too far into your green roofing project, have a professional determine the strength and weight-bearing capability of your walls. This is especially important if you are installing the new roof over your existing one.

3. Choose Your Plants

Think about what kinds of plants you want on your new roof. If you want to provide a sanctuary for wildlife such as bees, hummingbirds and butterflies, then plant flowering species. If you are concerned about the surrounding eco-systems and habitats, consider native plantings for your roof.
