Greem Roof System Over Sip Roof

We re debating between using modular trays to contain the soil or putting it straight on the roof with membrane or metal roofing over sip surface.

Greem roof system over 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. Green roof development involves the creation of contained green space on top of a human made structure. Green roof would be 4 inches of soil plants. Several assemblies that prevent shingle ridging are described in the builder s guide to structural insulated panels sips.

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. When the house was built melton sealed the seams between roof panels with tape applied on the bottom of the panels. We re planning to use steel sips to put a low pitch flat roof on an existing brick 2 story building 25 x30. 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.

Load would be 25 lbs per sq ft. Specifying a cold roof or simply over sheathing the roof. 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. 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.

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.
