A green roof is an innovative form of roofing where you cover the roof of a building, either partially or fully, with vegetation. This type of roof has a surplus of benefits and is a unique way to go about what is normally empty space. Green roofs are catching on in popularity all over the world as ways to not only use previously “dead” space, but also to help bridge the gap between asphalt and soil, helping the environment in new, exciting ways.

Why Green?

There are many benefits to having a green roof. Having a green space among so many constructed facades is a unique aesthetic rarely seen in the “concrete jungle”. Having a vibrant, living green roof not only looks great, but also has a whole host of benefits. Green roofs can be used for storm-water management, providing water to the new plants, which then return the water into the atmosphere through evaporation. A green roof can hold a certain amount of water, which delays storm-water runoff and lightens the load of sewer systems at a time when it is truly needed.

A green roof in an urban environment moderates the Urban Heat Island effect (where urban environments absorb and trap heat), improves air quality, and captures airborne pollutants, all of which contributes to a better, cleaner environment. In addition, they also reduce outside noise by 40 decibels, which can make a loud truck into a minor annoyance.

Green roofs also contribute to energy efficiency. They add greater insulation, which can reduce the amount of energy used to moderate building temperature. Researchers have found that an extensive green roof (15-50 lbs. per sq. ft.) can reduce daily energy demand from air conditioning by 75%. If it can do that for an office, imagine what it can do for a home.

A green roof can also be used to grow food, which can not only reduce someone’s carbon footprint, but also create a local food system. A green roof can also contribute to better water quality, increased biodiversity, and a better sense of community. Building a green roof is worthwhile for anyone looking for a project that’s not only rewarding but also environmentally-friendly.

What Does This Have To Do With Sani-Tred?

A green roof has 3 integral layers: vegetation, a growing medium, and a waterproof membrane to separate the “green” from the “roof”. The vegetation gets the water it needs while the roof doesn’t, much to the delight of people underneath. And one of the many things Sani-Tred can do better than any other similar product is waterproofing. Using Sani-Tred to waterproof a green roof guarantees the happiness of both plants above and people below. The new vegetation will flourish in a new space and people inside will feel good knowing they’re helping the planet (and that their shoes are dry). A green roof is a wonderful project for the do-it-yourself-er who likes to build, but also cares about the environment.
