Intersection Of Stucco Wall And Roof Waterproofing

N coordinate the stucco assembly installation with other trades on the project.

Intersection of stucco wall and roof waterproofing.

This absorbed water carries the cement paste into the voids in the cmu a process commonly known as wetting out where it cures and locks the two together. In addition wrb paper should be installed at the soffit line and at the top of the stucco walls. In this video kirk giordano demonstrates how to counter flash the bottom of a stucco wall over the step flashing of the roof so that no one has to jackhammer your walls just to fix a roof. With sections where the roof does not extend over the stucco wall or where the stucco wall and roof intersect a special type of metal flashing called kick out flashing must be installed to prevent water intrusion.

The bond of the stucco to the cmu is achieved by the concrete masonry absorbing the water from the fresh stucco. We used two layers of jumbo tex building paper over open bay. Many areas of air and water resistive barrier coatings must be installed prior to other construction components such as windows louvers doors roof intersections deck headers. Lay 2x4 blocks on the roof to set a consistent height for the weep screed flashing.

The next problem area is where the roof and stucco meet. With sections where the roof does not extend over the stucco wall or where the stucco wall and roof intersect a special type of metal flashing called kick out flashing must be installed to prevent water intrusion. Many flashings must be installed prior to stucco. The next problem area is where the roof and stucco meet.

Roof to wall intersections. There have always been problems with the flashing details at the roof to wall intersections of head walls rake walls and chimneys especially if brick or stone veneer or stucco is used.
