Re: Brick walls on top of gable roofs

[Subject Prev][Subject Next][Thread Prev][Thread Next]

The prefered method, of course, is to run the masonry down to the foundation. I do
not recommend supporting masonry off of roof trusses or any other type horizontal
wood member because of the long term sag which will eventually occur. Lagging a
steel angle to a full height stud wall may be an  option, depending on how much
load is actually being supported. Proper details must be developed and used.

If a support angle has to be sloped, I use small keeper plates welded to the angle
to engage the brick and prevent sliding of the brick along the angle. Locate the
plates in the head joints.
