Greem Roof System Over Sip Roof

We re planning to use steel sips to put a low pitch flat roof on an existing brick 2 story building 25 x30.

Greem roof system over sip roof.

Green roof development involves the creation of contained green space on top of a human made structure. The elastomeric base ply paradiene 20 tg is engineered to retain its elasticity through the rigors of deck movement. Green roof would be 4 inches of soil plants. Specifying a cold roof or simply over sheathing the roof.

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. Load would be 25 lbs per sq ft. 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. Several assemblies that prevent shingle ridging are described in the builder s guide to structural insulated panels sips.

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. 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. Vegetated green roof systems teranap multi ply sbs modified bitumen systems the torch applied two ply teranap system is based on siplast s proven roof membrane design.

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.
