Rubber Roof Meets Brick

The roof framing itself in this situation is much like any other traditional.
Rubber roof meets brick. That lip is then set into a reglet or groove in this case cut into the mortar joint of the brick wall above. Metal roof flashing is a galvanized sheet metal that is bent at a 90 degree angle about 8 to 12 inches on each side of the angle. It is used to seal the gap between walls and intersecting roofs. It comes in 10 foot lengths or for step flashing 6 inch lengths.
These kinds of houses often have a roof that butts against a wall. Many of these incorporate a rubber seal with an aluminum flashing. Look for cracked rubber around the plumbing pipe. It is commonly used in two story and side split houses.
When the roof of an addition garage porch or patio meets a brick wall the intersection creates a number of concerns. Metal roof flashing can be use to seal gaps between roof walls. The rubber can fail in as little as 10 to 15 years. Metal roof flashing is a galvanized sheet metal bent at right angles with about eight to 12 inches on each side of the angle.
Newer vent flashings are a concern of mine.
