sloped bond beam
(OP)
We called out a continuous reinforced masonry bond beam near a roof. The roof elevation slopes. The bond beam is acting as a chord. Is it common for the bond beam to slope with the roof? Is this easy for contractors? How is this done since blocking is in 8" increments? Would it just be better to place the top of the bond beam near the low point of the roof and just keep it at one elevation? There is an approximate change in roof elevation along the wall of 2'-0". Thanks.

I use stepped bond beams. The bond beam starts at the lowest point in the wall, and runs until there is a full course of masonry above it, then steps up to the next course. I generally show to overlap the lengths of the two beams 2 to 4 feet (depending on bar sizes used in the bond beams) so the bond beam is 'spliced'.

The bond beam is as deep as you want it. The top of the concrete slopes with the roof. The bottom will step with the cmu. The rebar may be laid on top of the masonry or put up on chairs and usually slopes with the roof to be parallel with the top of the bond beam.
