The sitch...
I am getting ready to install the final pieces of roof flashing on a shed roof (metal roof) where it meets a second story brick wall. I've had some special flashing made with a "V" bend at the top that will set into a groove cut in the brick. This was recommended as an extra measure to ensure that rain water does not enter at this joint. The house is quite old and the entire exterior was re-pointed about nine months ago. But when I cut the groove into the wall, about 1" deep, the older mortar is still present in some place and basically just crumbles away.
The part that has got me scratching my head is...
What type of adhesive/sealant should I be using to close the gap between the metal and masonry? If the old crumbly mortar is a serious issue, is there a product I can treat it with to ensure the adhesive/sealant does the job its supposed to?
Many thanks!
