Roof leaks present multiple challenges for homeowners and building owners. They never occur at a time which is convenient and they can lead to significant damages on the interior of the structure. Their effects can linger long after the repair has been made in the form of mold growth on interior surfaces.
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 roofing repairs.
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.
What are the ideal condition for roof leak investigation?
It is best to see the leak occurring. In order to trace a leak back to its original source it is best to visually see the active leak instead of depending on the remnants of the leak such as staining on the ceiling.
Stains can be used to locate roof leaks, but they may not reveal the entire story behind the roof leak.
In order to see the leak occurring it will be necessary to trace the leak during a rain or snow. If this is not possible, it may be necessary to conduct a water test on the roof surface by saturating the suspected area with a garden hose for a period of time until the leak occurs on the inside of the building.
