Putting in roof flashing in opposition to a wall is an important step in stopping water injury to your house. Roof flashing is a skinny metallic sheet that’s put in over the joint between the roof and the wall. It helps to direct water away from the joint and prevents it from seeping into the wall.
There are various kinds of roof flashing out there, however the commonest kind is L-shaped flashing. L-shaped flashing is comprised of a single piece of metallic that’s bent into an L-shape. The vertical leg of the flashing is put in in opposition to the wall, and the horizontal leg is put in over the roof shingles.
