Even the least agile among us should be making a minimal effort to be a little green (in one way or another).Â Green roofing is one of those things you can possibly handle yourself, if you’re not afraid of plummeting 50 feet to your eco-friendly death.Â In any case, This Old House claims that it’s not that hard.Â I can see Bob Villa now…
You know, guys, instead of asking semi-ridiculous questions, the lay-man can always check out Wikipedia.Â Since I’m feeling a bit froggy today, here is your straight from Wiki list of benefits of green-roofing.Â Don’t e-mail me asking about it until you read it.
Green roofs are used to:
- Provide amenity space for building users â€” in effect replacing a yard or patio
- Grow fruits, vegetables, and flowers
- Reduce heating (by adding mass and thermal resistance value) and cooling (by evaporative cooling) loads on a building â€” especially if it is glassed in so as to act as a terrarium and passive solar heat reservoir
- Reduce the urban heat island effect
- Increase roof life span
- Reduce stormwater run off â€” see water-wise gardening
- Filter pollutants and CO2 out of the air â€” see living wall
- Filter pollutants and heavy metals out of rainwater
- Increase wildlife habitat in built-up areas â€” see urban wilderness
A green roof is often a key component of an autonomous building.
You can get the This Old House DIY Green Roof Guide here.Â Here’s a little excerpt from Stephen Milioti’s article:
Not that you canâ€™t find the engineer, roofer, nurseryman, and architect to professionally install a green roof. But everyone loves an option that cuts out extra labor, materials, and middlemen. Thatâ€™s why the eco-obsessed editors here at This Old House had to see GreenGrid, a DIY green-roofing kit. Its freestanding modules ostensibly give the same benefits as green roofs the experts installâ€”if your roofâ€™s already sound, fairly flat, and watertight. Donâ€™t bet on the same polish as with a pro team. But you may see the usual improved cooling and heating and reduced rainwater runoff. (Weâ€™ll see how our kit fares.)
