Have you ever heard of green roofing? If you haven’t, you aren’t alone. Green roofing is definitely not among the most popular roofing materials, but it has been making more of an appearance here and there now that more and more homeowners are striving to create environmentally friendly homes. There are a lot of questions about green roofing, however, and answers seem to be tough to get since green roofing is not popular. Here are a few facts about green roofing, and why it should be consider if you are looking to “go green.”
What is it
According to House Energy, there are a few different options for green roofing, but typically it involves a layer of soil topped with small shrubs, herbaceous perennials and grass. The easiest form of green roof is called extensive green roof, and it includes a thin layer of soil, low growing and drought tolerant plants, as well as succulents, herbs, mosses and grass. Another type of green roofing is called semi-intrusive green roof, and this includes a thicker layer of soil, with more shrubs. The third type of green roofing is called intensive green roof or roof gardens, and this includes the deepest layer of soil, perennials, bushes and even trees. Most green roofs can be found on business buildings, but they are making more of an appearance on homes.
How is the cost
Green roofing is not as expensive up front as many other roofing materials are, and their cost can be compared to yard maintenance as you have to plant and re-plant here and there, install filters, purchase new soil and maintain a drainage system. Green roofing materials can cost anywhere from $12 to $24 per square foot, and can increase depending on the shape of your roof and the type of system it requires. Green roofing is more expensive to maintain than other roofing materials, but many homeowners find the extra cost worth it when it comes to the advantages of green roofing.
Pros and cons
Obviously the major pro of green roofing is how environmentally friendly it is. Green roofing improves air quality primarily in urban areas, and minimizes heat effects. Green roofing is also great insulation without a hefty cost for homeowners, which increases protection and lowers energy bills. Obvious cons of green roofing is simply the maintenance. They require a lot of tender love and care just like the upkeep of landscape. There is no such thing as minor damage when it comes to problems with the roof, so homeowners have to constantly be watching the system for potential problems so they can prevent major home damage.
