Green Roofs On Pitched Roofs

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.

Green roofs on pitched roofs.

A technical review of the project is essential. Steeply pitched roof 30 45. Planted sloped or pitched roofs look great and due to their high visibility they have been the focus for several new projects. Sloped roofs retain less water in general and the moisture content varies from the ridge to the eave lowest edge of the roof.

In addition to green roofs on flat surfaces a green roof on a curved or sloping surface can be a real eyecatcher. Green roofs are a perfect solution to create green spaces on any type of surface. 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. A pitched green roof constructed from treated timber.

Steep pitched green roofs up to 35 georaster elements to transfer high shear forces into the roof structure the system build up steep pitched green roof based on the zinco georaster elements enables the installation of green roofs with slopes exceeding 25 and up to 35. Why choose the hydropack tray to green a steep roof. From 10 on the green roof system build up differs significantly from system build ups below 10. Read below about our green roof system for sloping roofs to transform your roof into a sustainable green roof.

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. Steep pitched green roof with hydropack contents. Slopes above 25 degrees are normally considered too steep to walk on and require additional design features. Above 5 degrees roofs are considered to have a pitch which may affect the design.

Typically the studded oldroyd xv green membrane is laid over a suitable exterior grade bitumen based roofing felt to form a waterproof drainage layer. The substrate layer has to be protected against erosion. Shear forces increase with the roof slope and have to be transferred into stable beams. Sempergreen has the perfect solution for sloping roofs.

In order to achieve lasting success with a sloped extensive green roof there are a few basic things to consider. The two most common types of green roof specified for commercial and residential developments are sedum and wildflower. If not properly secured a pitched vegetated roof can erode and slip under heavy rain excessive irrigation or poor plant growth. The turf or sedum layer is then laid directly over the oldroyd xv membrane.
