WHAT IS A GREEN ROOF?
A green roof serves as a natural extension of the displaced landscape atop your home. Beyond its obvious visual appeal, these lush rooftops offer a multitude of environmental and wellness benefits. Extensive research has shown that exposure to nature has numerous positive effects on human well-being, including stress reduction, lower blood pressure, regulated heart rate, and decreased muscle tension.
Introducing greenery into previously barren areas within the home enhances overall wellness. Additionally, many green roofs are designed to be usable spaces, providing outdoor areas that may be lacking on some properties. Moreover, the soil layer helps reduce noise pollution, particularly beneficial for homes located near busy streets or urban centers.
From an environmental standpoint, the vegetation on green roofs acts as a natural buffer, absorbing sunlight, wind, and rain. This significantly reduces rainwater runoff, easing the strain on drainage and municipal septic systems. Furthermore, by reducing heat transfer through the roof, green roofs enhance energy efficiency within the home. Additionally, the protective layer of vegetation extends the lifespan of underlying roofing materials and membranes.
HOW DOES IT EFFECT BUILDING COSTS?
The upfront costs associated with installing a green roof are notably higher compared to conventional roofing options. However, if designed and implemented correctly, the long-term benefits may outweigh the initial investment. To break it down, a green roof in our region typically costs between $25 to $40 per square foot.
This estimate excludes the waterproof membrane beneath the green roof and any irrigation system that may be required. Additionally, ongoing maintenance expenses for nurturing the vegetation, especially during the initial years post-installation, must be considered. These costs can accumulate rapidly. However, the potential for decreased utility expenses over time may offset the initial investment.
Moreover, it's crucial to assess whether additional structural support is necessary for homeowners opting for green roofs. Engaging in this discussion early on can mitigate unexpected construction expenses and result in the creation of a serene natural retreat atop your home.
