Green roofs are a perfect solution to create green spaces on any type of surface.
Green roofs on pitched roofs.
Above 5 degrees roofs are considered to have a pitch which may affect the design.
In addition to green roofs on flat surfaces a green roof on a curved or sloping surface can be a real eyecatcher.
Most vegetation will grow on quite sever slopes but the designer must consider the practicalities of installing the green roof and just as importantly how the roof is to be maintained.
Typically sedum has a more consistent appearance throughout the year compared to a meadow green roof in which volume and evenness of growth fluctuates within and between seasons.
The most crucial component of any sloped green roof is the confinement system which holds the growth medium in place during the roof s early stages of development.
The substrate layer has to be protected against erosion.
A pitched green roof constructed from treated timber.
Sloped roofs retain less water in general and the moisture content varies from the ridge to the eave lowest edge of the roof.
The turf or sedum layer is then laid directly over the oldroyd xv membrane.
Typically the studded oldroyd xv green membrane is laid over a suitable exterior grade bitumen based roofing felt to form a waterproof drainage layer.
Steep pitched green roof with hydropack contents.
If not properly secured a pitched vegetated roof can erode and slip under heavy rain excessive irrigation or poor plant growth.
Steeply pitched roof 30 45.
Read below about our green roof system for sloping roofs to transform your roof into a sustainable green roof.
In order to achieve lasting success with a sloped extensive green roof there are a few basic things to consider.
Why choose the hydropack tray to green a steep roof.
The two most common types of green roof specified for commercial and residential developments are sedum and wildflower.
Pitched roofs start with a slope of 10 18.
It is essential to conduct a technical review of a planting project on a steeply pitched roof in order to limit the risks of erosion and to recommend the most appropriate retention device.
Slopes above 25 degrees are normally considered too steep to walk on and require additional design features.
From 10 on the green roof system build up differs significantly from system build ups below 10.
Sempergreen has the perfect solution for sloping roofs.
A technical review of the project is essential.
Shear forces increase with the roof slope and have to be transferred into stable beams.
