Green Roof Structures

Green Roof Structures

Green Roof Structures

(OP)
While browsing through various blogs and forums, I came across a forum where the discussion was about a green roof house. The roof of the house is covered with thick coat of mosses and it is all green through out the year. I wondered that we always say ask the house owners or building owners to make sure that there should not be water settling or ice set on the roof, unless they are well maintained. And even the roofing services residential/commercial always recommend proper maintenance of the roof, so that the settling of water doesn't lead to premature aging of the roof.
This green house has caught many interests and there are people who actually are requesting such roof. Is this to be promoted, because knowingly we will be taking a risk with a roof which will be 365 days wet. What's your thought on this?

RE: Green Roof Structures

There should be a properly designed drainage layer underneath the 'living' layer and immediately above the waterproofing layer. The drainage layer should allow for free flow of water towards a drain, or off the side of a sloped roof. There are many products on the market that provide this drainage layer.

RE: Green Roof Structures

As Canuck said, there is a lot more to a green roof than the plant matter. These aren't simply plants growing on the roof, but growing in the roof membrane.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
