Parapet Roof Intersection

Wind uplift resistance parameters at last achieve meaningful values with a suitably elevated protective height parapet.

Parapet roof intersection.

Parapetitus they have a long history which of course is not always clear that allows me to embellish without threat of peer review reversal. If there s no other way to address this maybe you could use tji blocking knock out a few of the pre punched web holes and call it vented. While a roof parapet wall may seem like a small detail in the grand scheme of the entire building design it can actually change the dynamic of an entire roof both in terms of cosmetic detailing and safety. The parapet is so much more than the intersection of roof and wall.

Roof membrane must lap up wall to minimum of 12 above roof plane or per specifications whichever is greater. The flat roofing material must go up the wall a minimum of 12 or up the wall and over the top of the wall if the wall is less than 12 high. 4 1 roof to wall junction 78 4 2 roof junction detail 81 4 3 tricky lean to junction 85 4 4 so t detail at gable verge 88 4 5 parapet or balustrade to wall junction 90. The most common mistake at this intersection is to allow the metal coping to but up to the wall without the application of termination metal.

A critical and often overlooked design detail is at the termination of a parapet coping at a wall. Insulate within parapet wall cavity to depth of roof insulation if present. It s also the junction where building aesthetics meets structural performance air and moisture management energy efficiency construction trade sequencing and operational maintenance. I just use a fairly dense cant strip over top of that intersection between the roof and parapet and it seems to be working fine.

Yes even flat roof to wall intersections are not being properly done. Just as the roof parapet historically served to provide building occupants with a safe barrier against external attack the railing height roof to wall intersection for garden roof returns it to its primarily protective role. A parapet roof is a flat roof with the walls of the building extending upwards past the roof by a few feet around the edges. 1 their major function today aside from confusing architects is to protect the edge of roof assemblies from wind uplift forces.
