Commercial Roofing in Chicago
If you’re in need of a new roof for your commercial building and looking for something a bit different, vegetative roofing may be just the thing for you. Vegetative roofing refers to a roofing system in which plant materials are installed over a weatherproof membrane. These types of roofs are very unique and they provide many benefits to the building, its occupants, and the environment.
Storm Water Retention
Depending on the individual design of your roof, a vegetative roof or green roof can typically reduce your building’s total storm water runoff by 50 to 90 percent, due to the plants absorbing and using much of that water to grow and flourish. In addition, the peak flow volume is greatly reduced as well as the peak flow period being delayed by as much as 4 hours. These features are a win for everyone, keeping your plants healthy while minimizing a storm’s impact on city sewer systems. The more water that can be used purposefully as it falls from the sky, the less will end up flooding local roads and other areas.
Added Thermal Resistance
Green roofs are one of the most effective thermal insulators, keeping you warm in the winter and cool in the summer. This helps to keep temperate air inside the building and reduces thermal gain. All of this will greatly reduce the energy consumption your building uses to heat and cool rooms over the course of a year. This is a great savings both in terms of energy used and money saved. It’s good for both the environment and your bottom line!
Reduced Noise Levels
That extra insulation doesn’t only work on heat and cold, but it can also stop pesky noise from passing through. Typical extensive green roofs (with 3″ – 4” of growing media or soil) reduce reflective sound by up to 3 dB and improve sound insulation by up to 8 dB. This is great for anyone, but an absolute lifesaver for buildings near airports, train stations, construction projects, or busy freeways.
Increased Roof Longevity
A green roof, with all its soil and plants, acts as a protective barrier for your roof against nasty things like hail, extreme temperatures, UV rays, and other weather events that may damage it over time. This added layer of protection can help your building’s roof last much longer than its usual lifespan, saving you money on repairs and replacements down the line.
Additional Square Footage
Adding a vegetative roof is like tacking on an extra level of usable space to your building. Converting or designing normally unused roof areas into green roofs simply makes sense. Increase your property value by reclaiming a previously unusable space and turning it into a beautiful and functional rooftop garden for your building’s occupants to enjoy at their leisure.
More and more townships, municipalities, and other government agencies are providing incentives that can help off-set the start up costs of installing a green roof through special tax write offs and other programs. Check with your local government official or tax professional to see if your building is eligible for any such incentive. You may be surprised at how affordable these programs can make your green roof.
Mitigates Urban Heat Island
Green roofs naturally cool and humidify the air surrounding them, creating a microclimate which helps counter the usual heat-spewing buildings in the city and regulate the temperature back to a normal level.
Natural Habitat for Local Wildlife and Plant Species
Green roofs promote biodiversity by encouraging wildlife such as birds, butterflies and insects, to remain within urban areas they would otherwise be forced out of due to changes in habitat and lack of areas to flourish.
Reduction of Dust and Smog Levels
Vegetative roofs can clean up our cities. Plants naturally help to filter out dust and smog particles as well as other pollution from the air. Nitrates and other aerosol contaminants are absorbed out of the air and rainfall and bound within the soil, making the air much safer to breathe. If every business adopted a green roof today, there’s no telling what kind of a positive impact it could have on our environment!
