Methods For Completing A Brief Internal Parapet Wall?

The height of roofing at the wall should be at least 12″ to the top of the parapet, and TPO should not be lapped over the top unless required by unique construction conditions. The top of the parapet should be sealed with fluid applied flashing, and venting in wood-framed parapets may need to be provided. A continuous vapor barrier behind the exterior cladding of the parapet should provide a clear drain-age plane that redirects water away from the interior. This vapor barrier typically encapsulates the top of the parapet wall directly underneath the coping, transitioning along the vertical face of the wall, and down onto.

A well-designed parapet wall can help keep rainwater away from the building’s interior, as it has less of an opportunity to end up sitting on the roof membrane. Ponding water on flat roofs can lead to deterioration of the roof. When parapet walls are designed correctly, they can make your house look better and leave a lasting impression.

To prevent rainwater from getting into the top of the parapet, slope the top inward so they don’t stain the building façade. Parapet walls are extensions at the edge of rooftops that form barriers to prevent people falling over, minimize dust and air loads, and prevent water seepage.

To design parapet components, consider creating a second wall type for above the parapet or using masking regions to hide what you don’t want to see above. Natural stone and brick can be used as parapet materials, and stucco can still be used as a coping cap. Wall coping is essential for parapet walls to prevent moisture entry and water seepage.
