Many things can cause a leaky roof.
Sometimes a roof leak is the result of a roof that has exceeded its serviceable life. It has deteriorated so it can no longer serve as an adequate water barrier. Sometimes the leaky roof is a result of an act of nature, such as a falling limb. Then there is the most troubling reason: when an otherwise good roof starts leaking.
A problem with a vent or your flashing is the most common areas that cause roof leaks. Why? Because two different materials are merging: your roofing material and a metal flashing or vent. Both materials have the same goal of keeping your roof waterproof, however they don’t automatically blend together and need other methods to prevent roofs from leaking.
The most common method typically used is adequate overlapping. This is so a piece of venting or flashing goes far enough under the roofing material so that water will not run underneath it. While you might think that there is a lot of sealing or caulking used to waterproof a roof, generally that is not the case. Not much is used in relation to the volume of the entire roof. Skylights are another common leak area. They are waterproofed by one piece of flashing being snug against another going in the opposite direction.
Vents, flashing and skylights can occasionally loosen and get out of position. Once this occurs, the immediate area becomes susceptible to leaks. Replacement or Repositioning of the subject vent, flashing or skylight is required.
The Chimney on your roof usually requires additional sealing. Caulks and sealants are subject to deterioration from their constant exposure to UV rays water. Resealing such areas is periodically required in advance of a leak. A free roof inspection from Exterior Care PDX will help spot any problems before they happen.
