Residential Roof Valleys Are A Common Source of Roof Leaks

A roof valley (as picture to the left) on your residence is defined as an area where two adjoining sloped roofing surfaces meet together and form a “V” shaped depression on your roof. There are varying degrees of slope depending on how steep the roof is installed on your home. Needless to say, there are several reasons a valley on your house roof is a prime leak area. Therefore it is extremely important to take proper precautions when repair roof leaks or installing new or re-roofs.

More water naturally accumulates in valleys because of run offs during normal rainfalls and especially during heavy storms and deluges. Ice and snow also build up to a greater extent in valley areas during the winter months in the Illinois region. Subsequently there are additional amounts of water which flow down through the valleys as the ice and snow melt as temperatures rise.

There are several installation techniques, including open or closed valley installation as well as woven installations.. Each varies based on circumstances, construction, region, budget as well as the type of asphalt shingle being used. Different techniques also present different looks or curb appeal. One installation technique even includes a metal water raceway in lieu of asphalt shingles in the bottom of the valley.

Regardless of technique and type of asphalt shingle selected, you should insure your roofing contractor installs both leak barriers and deck protectors in the valleys, as commonly referred to as ice and water shields. This helps prevent water which may leak up under the asphalt shingles in a heavy storm which could penetrate your roof if the preventative measures were not installed.

Because of the potential problems arising from improper or ‘low cost’ installations, you should only rely on a truly professional roofing contractor to get the job done right the first time. Make sure your roofing contractor carefully explains all of your options so you can make an informed and intelligent decision.
