Counterflashing skirt is recommended when pre-manufactured flashing flange extends less than 2 inches over membrane base flashing, or when membrane base flashing fasteners are exposed.
Metal curb flashings are designed for rectangular penetrations. These flashings are easily welded to the installed membrane and the combination of reinforced membrane and custom-fabrication ensures a long-lasting, watertight flashing.
This detail is intended to be used where wall heights are greater than 24" above roof surface. The profile of specific components, their configuration or sequencing, can vary with the roof system, climatic differences, and regional or area practices.
Overflow drainage scuppers are typically holes with no downspout or other intricate designs and can be used with roof drains or with primary drainage roof scuppers.
The profile of specific components, their configuration or sequencing, can vary with the roof system, climatic differences, and regional or area practices. Dimensions as shown are recommended minimums and are intended to be approximate to allow for reasonable tolerances due to field conditions. Flashing or stripping ply should extend into scupper throat, and be fully welded
Flashing or stripping ply should extend into scupper throat, and be fully welded. Seal exterior of scupper at wall penetration. Continuous cleats are recommended when flashing face dimension exceeds 3 inches and in areas deemed a high-wind zone as categorized by local building code.
The profile of specific components, their configuration or sequencing, can vary with the roof system, climatic differences, and regional or area practices.
Waterproofing Pipe PenetrationsPipe penetrations are often placed by the plumbing and electrical contractors in such a manner that it is impossible to properly install the required flashings.
