What Houzz contributors are saying:
2. Green roofs slow down runoff. In addition to intercepting the small storms, green roofs filter and buffer water during long, intense rainfall periods. Water takes longer to travel through the plant and other media layers on a green roof compared with a traditional roof, where water runs right off and is whisked into the roof gutters and down the spouts. Slowing down runoff returns water to the aquifer at a slower rate and reduces flooding downstream.
MaterialsThe roof slope has a direct effect on the materials a shed roof can be covered with. Any slope less than 2 inches in 12 inches is considered flat and must be waterproofed as such. Slopes between 2:12 and 4:12 are generally considered low slope, while those between 4:12 and 12:12 are considered conventionally sloped. Each roof material has its own limitation with respect to roof slope, beyond which it’s either not advisable to use, or special procedures must be followed to install that material. Having said this, with the right budget, (almost) anything is possible.
Education. Reducing the waste stream on a construction site means overcoming ingrained mind-sets and embracing an educational component during the construction process.Fostering a team approach where all parties are invested in this new way of working is critical. It helps that beyond the environmental and efficiency offsets, there are cost savings involved in being less wasteful too. And, with tipping fees ranging from $10 to $40 per ton, those savings can add up quickly. The education process starts with a commitment on the part of the client, architect, designer and contractor, and must follow through to each and every subcontractor involved for it to be successful. And a waste management plan can be the linchpin that makes this shift possible.More:23 Ways to Reduce Waste at Home6 Tips From a Nearly Zero-Waste Home
Newly constructed homes must meet the requirements of the designed loads, so as long as your architect and structural engineer are on the same page about your desires for a green roof, there should be no problem for a new home to meet the structural requirements. For retrofitted green roofs, you have to be a bit careful. Requirements will depend a lot on what part of the country you live in and what kinds of loads your home was originally designed to sustain (snow, wind, rain etc.).
