Rubber Roof Meets Brick

Look for cracked rubber around the plumbing pipe.

Rubber roof meets brick.

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. Metal roof flashing can be use to seal gaps between roof walls. These kinds of houses often have a roof that butts against a wall. It is used to seal the gap between walls and intersecting roofs.

The roof framing itself in this situation is much like any other traditional. It comes in 10 foot lengths or for step flashing 6 inch lengths. The flashing should dive up and under the shingles that extend up roof from the middle of the plumbing vent. Newer vent flashings are a concern of mine.

To install the roof wall flashing above the builder bent the top edge of the flashing into a 90 degree lip about 2 cm in width. When the roof of an addition garage porch or patio meets a brick wall the intersection creates a number of concerns. Metal roof flashing is a galvanized sheet metal bent at right angles with about eight to 12 inches on each side of the angle. That lip is then set into a reglet or groove in this case cut into the mortar joint of the brick wall above.

It is commonly used in two story and side split houses.
