Another caution on brick walls whether real or veneer is.... NEVER allow your Aerial to "slam down" on a roof edge when laddering a roof...this can & has caused the wall to pull away showering the street below.......another caution also although not real brick related but decorative is being cognizant of old (pre acrylic) stucco .....this adds a tremendous weight to a wall when added after the original build as a re model.
