5 Essentials to Consider when Planning a New Green Roof Installation

June 30, 2017

Green roofs, a long-standing concept in Europe, is now appealing to an increasing number of property owners in the U.S., too. The reasons for the shift are many. Green roofs last longer than other roofing solutions, absorb stormwater, reduce the need for expensive drainage systems, and reduce energy costs, by providing a natural insulation. If you are planning a new roof installation, consider green roof as an investment that will not only protect your property, but will also contribute towards environment protection. There are, however, a few things that both homeowners and roofing experts need to focus on when building a green roof.

Let’s take a look.

1. Type

There are two types of green roofs – intensive and extensive. Similar to ground level gardens, intensive roofs need to be well-maintained. You can grow any type of plant on intensive roofs. Extensive ones, on the other hand, are relatively lighter, require less maintenance and don’t require irrigation. If you don’t want functional benefits, opt for an extensive green roof.

2. Waterproofing

Depending upon the climate in your region, you roofing expert may need to apply multiple layers of waterproofing on the green roof for it to support vegetation. It is advisable to opt for a waterproof membrane such as a root barrier that also doubles as an irrigation system.

3. Location

Most plants need ample sunlight to grow, and therefore, it is important to see if the area where you are planning to build a green roof receives sufficient sun. If, however, your property is in an area where sunlight is a scarce commodity, you can opt for the plants that need limited sunlight.

4. Slope

To support plant life, the roof should either be flat, or if inclined, the inclination angle should not be more than 30 degrees. Flat roofs, however, provide the ideal ground to grow flora. That’s because sloped roofs retain less water, and the moisture content varies from the ridge to the eave.

5. Type of Plants

Choosing the right plants is important for the success of your environmental initiative. If you live in a dry area, choose plants that demand minimal water. Among others, delosperma and Sedum are ideal plants to grow in such a climatic condition.

Last Few Words

Building a green roof is an effective solution to counterbalance the environmental impact of a property. It is, however, important to focus on the factors discussed in this post, to ensure the roof looks beautiful and serves its purpose. In addition, the success of the investment largely depends on the workmanship that has gone into the new roof installation.
