Roof leaks most commonly occur at roof penetrations. Roof penetrations can’t be avoided and are a very common source of a leaking roof. Roof penetrations such as vent pipes, drains, skylights and electrical penetrations are all forms of penetrations and are subject to causing roof leaks.
When detecting roof leaks it is difficult to locate the actual source of the leak. Often times the water may leak around a roof penetration, follow a truss, and then find its way eventually to your ceiling several feet away from the original roof leak. If there is a roof or wall stain close to a common penetration we will always begin our search at the roof penetration to see if that is the cause. Often times we don’t need to look much father.
There are several methods used for sealing roof penetrations. Some roof systems will use a boot with a metal band or collar securely fitted to the penetration, other systems will require a pitch pan, and others will use flashings and membranes to close the roof opening. All of these systems have a weak link that can cause roof leaks.
Often times an annual roof inspection can help eliminate common roof leaks especially penetration roof leaks. During an inspection we can usually see either some cracking or pulling away of sealants or membranes from your roof components. When sealants or any type of pourable sealer begins to crack or if there is any settlement or movement in the roof it will cause a separation between the penetration and sealer. Finding these failing roof areas will prevent roof leaks and greatly reduce the damage caused by finding the leak after it occurs.
Any roofing material disruption, corner, valley or penetration is a source of a roof leak. Many times a very simple resealing of a roof opening can eliminate costly roof leaks and roof repairs. Annual inspection can greatly reduce the occurrence of these roof leaks and add several years to your roof installation.
