Blue Roof Membrane

Maintenance of blue roof systems focuses on the periodic removal of sediment and debris from outlet and storage areas in order to prevent clogging and limit deterioration of the roof membrane.

Blue roof membrane. It is the simplest blue roof that can be created. These designs utilize a roofing membrane or waterproofing system as the primary water detention structure. It is the simplest blue roof that can be created. Which is integrally laminated to a blue high density polyethylene film.

A blue roof is a roof of a building that is designed explicitly to provide initial temporary water storage and then gradual release of stored water typically rainfall. A blue roof can be created on a typical hydrotech pmr protected membrane roof assembly utilizing standard loose stone for ballast. The membrane is specifically designed to be self adhered to a prepared substrate providing a high performance waterproofing barrier. Blueskin wp 200 is a self adhering composite membrane consisting of an sbs rubberized asphalt compound.

Using standard ballast stone the water in the blue roof is stored within the void spaces of the stone and to the required level above the ballast. Maintenance activities can generally be performed by individual building owners or site maintenance staff as needed. Blue roofs are constructed on flat or low sloped roofs in urban communities where flooding is a risk due to a lack of permeable surfaces for water to infiltrate or seep back into the ground. Blue roofs can be situated above the waterproofing membrane in a warm roof system or above the water flow reducing layer in an inverted application at both roof and podium levels.

Waterproofing membranes with welded seams and monolithic membranes which have a proven performance history in similar applications are appropriate materials for blue roofs. Roof integrated designs roof integrated designs are built during new construction or modifications of existing roofs to intentionally store standing water over extended periods. The waterproofing membrane for a blue roof must be able to tolerate more frequent ponding water events for longer durations. The four primary blue roof types are described below.

Bauder blue roof outlet manufactured from hdpe classification 2 which is widely recycled. The bauderblue roof system can be constructed at either rooftop or podium level. The designed void space between the flat roof waterproofing membrane and hard or soft landscaping finish allows the stormwater to attenuate.
