Any penetration point in your roof is considered a leak prone area and should be the first place you look when trying to locate a leak. Pipe vents are the most common type of penetration found on a roof and are from bathrooms, dryers, and some high efficient HVAC units. Each PVC pipe is typically wrapped in a boot and rubber doughnut. However, these boots can leak over the years.
Hot summers can eventually crack and tear the rubber seal around your vent pipe. These should be inspected every year, to keep you from finding out, after the fact, that you have a roof leak. In addition, when the rubber separates, water will enter your attic space and typically track down a rafter. This allows the water to enter your ceiling from a place far away from where the actual leak took place. Just because the leak is not showing up in your home directly below the vent pipe, inspect anyway, this may solve your problem.
To repair the vent pipe, you can purchase a new boot from a local hardware store. Or, if you are needing something repaired quickly and easily, you can simply layover a new donut or rain collar. These can be picked up for just a few dollars and are extremely easy to install. Typically you will need to trim the size of the hole, which is perforated, and then slide it over the top of the pipe. Then, slide the new rubber seal down the pipe to the boot, and pull it tight against your roof line or upper part of your boot.
By repairing your vent pipe, you are saving yourself hundreds of dollars in damage inside your home. Mold growth in the attic can be very costly to have cleaned and sanitized. In addition, damaged drywall requires replacement and painting.
Remember, if you have a leak, check your vent pipes. But if possible, do a roof inspection once a year to make sure all of your roof penetrations are not damaged or deteriorating.
