Green Roof System Over Sip Roof

Green roof development involves the creation of contained green space on top of a human made structure.

Green roof system over sip roof.

Specifying a cold roof or simply over sheathing the roof. Build for the future with extreme s structural insulated panels sips the high thermal values and strength properties of extreme s sips are highly beneficial for roof construction. Several assemblies that prevent shingle ridging are described in the builder s guide to structural insulated panels sips. I was wondering if anybody has done or has recommendations about a green roof over a sip roof.

Green roof systems may be modular with drainage layers filter cloth growing media and plants already prepared in movable often interlocking grids or loose laid built up whereby each component of the system may be installed separately. The roof structure is 10 25 sips on a 2 12 pitch and the developers are going with either metal roofing or a torch down system. The key to every good building is a good roof. We maintain consistent r value throughout the e sip home panel kits and past the exterior wall see diagram.

The pitch of the roof is very low only 1 2 inch in 12 and the metal roofing has been applied directly over the sips with no air channel beneath the roofing for ventilation. Extreme s pre insulated sips offer an option for a high performance roof framing solution that is 15 times tighter than conventional construction practices making it easier to control indoor air environment. Zip system roof assembly combines our revolutionary integrated sheathing and flashing tape or liquid flashing to provide a sealed roof for protection against moisture intrusion during construction or if high winds strip the roof covering away. And no matter what build system you use sip energy s structural insulated panels are the fast efficient way to roof insulate your building in one easy pass.

Todd i am a designer sip material supplier and i am looking at a large townhouse project. When the house was built melton sealed the seams between roof panels with tape applied on the bottom of the panels. A strong resilient roof is a home s first line of defense when the roof deck is exposed to weather. Getting full insulation coverage over the entire ceiling is easy with our e sip roof panels.

Green roof would be 4 inches of soil plants. Our e sip panel is made up of expanded polystyrene eps. Options include a persist roof a hybrid design that includes rigid foam over the sheathing and dense packed cellulose in the rafter bays or an uninsulated roof over a vented. Unique services internal to panel.

Load would be 25 lbs per sq ft. The ridges caused by the expansion of sip roof panels may be an aesthetic blemish but it does not affect the performance of the roofing or the sip roof panels.
