When should flashing be used?
Flashing is critical to certain areas of your roof — namely, the places where the roof surface meets a wall (sidewalls and front walls), the low points where two roof slopes meet (called valleys), roof protrusions (bathroom/kitchen vents, skylights) and the roof's edges (rakes and eaves).
