Roof Flashings for Pipes

There are many types of flashings that can be used on a Jacksonville roof but today I’d like to talk about those flashings that seal the plumbing pipes at the roof elevation. You may wonder why I even mention this type of flashing because it is way up on the roof and probably will never become a concern. But, yes, some day these flashing might fail and it would be helpful for you to understand what these roof components do.

Usually encased with a rubber material that is stretched around the pipe. The rest of the flashing body is usually aluminum that is hidden under the roof shingles. Normal roof shingle life in Somerset, Jacksonville is about 25 years and the normal- no maintenance life of this type of roof flashing is 15 years. Hence there is a discrepancy. What happens here is the rubber flange holding the venting pipe starts to crack. Even a small crack can let a large amount of rain water inside. This leakage will be prominently displayed by a water stain on the ceiling that you will notice when casually walking into the area of concern.  No need for alarm, yet.

What is normally a typical repair is to seal the pipe and rubber bushing with roofing tar. No need to replace the entire roof flashing. As was stated before in this article, even a small crack can let in a lot of water.  These small holes/or cracks are also an easy access for flying insects to enter the house.

Here in Somerset Jacksonville, stinging insects such as wasps and hornets are prone to fly around at roof elevations for the purpose of finding a safe, dry nesting area. These flying insects are out and about everyday. A vacant attic space would make for an ideal home for them but on the other hand, may create a very undesirable situation for yourself and your family as they eventually will find a way from the attic into your living space. Yikes!
