Grass Roof Construction

I liked the idea of having a bit more greenery in the property we live.

Grass roof construction.

Build a living roof green roof. Extensive green roofs normally have an attractive low layer of vegetation around 80 100mm high such as grass moss sedum or small flowers. Bitumen roofing felt is nailed to the sarking and a dimpled cavity drainage membrane is laid over the top dimples face down to form a drainage layer. A green roof is in ecological terms a great and simple thing to do.

To attach the membrane to the roof structure use asphalt mastic. The stud construction of the typical frame structure for instance doesn t lend itself to sod roofing but log cabins and buildings of post and beam design are especially well suited for such a. It replaces the ecology the new house sits upon thereby replacing the habitat that a house takes away. Used over a whole roof a green roof will be the single overriding design influence on the house as well as impacting on the construction right down to the foundations.

This thick sheeting will be the grass roof waterproofing membrane. In modern turf roof construction bitumen roofing felt combined with dimpled plastic drainage membranes are usually used in place of birch bark. Sedum green roofs are the most common type due to the hardiness and low maintenance requirements of the plant. The overlapping of two plastic sheeting must be at least 4 inches.

Make a normal flat or sloped roof into a beautiful living garden. While redeveloping our house we decided to install a living roof on our kitchen roof why you ask.
