Roof leaks are not always caused by damaged or missing shingles. Roof problems may actually be due to broken or improper roof flashing. Repairing the flashing or providing new flashing may be all that is needed to make the roof watertight again. What is flashing? Flashing refers to thin continuous pieces of sheet metal or other impervious materials, offering extra protection at prone points of the roof. The function of flashing is to provide a watertight junction between roofing materials and roof projections or other parts of the structure, and between roof sections. The most common locations for roof flashing are at valleys,chimneys, roof penetrations, eaves, rakes, skylights, ridges, and at roof-to-wall intersections.
Many flashing problems can be reduced or eliminated by regularly scheduled inspection and maintenance. Save yourself the chore of repairing and painting ceilings and walls that were stained by water leaks and add 'check flashing' to your honey-do list.
