Roof leaks present multiple challenges for homeowners and building owners. Sometimes determining the source of the roof leak can be an even greater challenge. The source of the roof leak on the outside rarely matches where the leak shows on the inside. This leads to a good deal of frustration in attempting to repair the leak. Locating the source of a roof leak is not an exact science. It is a process of elimination due to the fact that a roof leak may have several contributing factors and may not always be the direct result of one specific problem associated with the roof.
