How to vent a flat roof with parapet wall.

Incidentally another benefit parapet walls is that they help conceal such eyesores. A parapet is a barrier which is an extension of the wall at the edge of a roof terrace balcony walkway or other structure. Can use round louvered soffit vents to limit bulk water intrusion if venting holes are in exposed locations. Coming from me it should by now.

Instead the air is vented through the roof to the parapet walls the parapet then incorporates a continuous strip vent beneath the cap flashing. If cavity is greater than 12 above roof insulation provide high low venting in each wall cavity. For areas which do not need above cover hole with bug screen. Alternatively you can drill lots of holes to connect the joist spaces or use web trusses and then install vents in the flat roof surface as in commercial.

Normally you would find the venting at the soffit the underside of the roof overhang but that s not possible with the parapet. 2 i call them the baker principles. Connect the water control element layer of the roof to the wall the air control element layer of the roof to the wall the vapor control element layer of the roof to the wall and finally the thermal control element layer of the roof to the wall. That way you can use the parapet wall to detail a vent in the back side of it.
