Putting in roof flashing towards a wall is a vital step in stopping water injury to your property. Roof flashing is a skinny steel 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 several types of roof flashing out there, however the most typical kind is L-shaped flashing. L-shaped flashing is created from a single piece of steel that’s bent into an L-shape. The vertical leg of the flashing is put in towards the wall, and the horizontal leg is put in over the roof shingles.
