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.
A new roof can provide safety and security for your home and family. However, a roof does not consist of shingles alone, but many roofing components that create a barrier to the weather, while allowing harmful elements to escape your attic and home. It’s important for any roofer to understand the components they work with, to ensure that your home’s HVAC and other ventilation is properly installed.
All roofing penetrations must be suitably removed, installed, and inspected when you receive a new roof. This includes common pvc vents, furnace flues, and chimneys that must all be either replaced or repaired. When having a new roof installed, confirm with the contractor that the vent boots are being replaced and properly sealed. For furnace flues, make sure the roofing contractor understands the components they are working with, to allow the proper ventilation of harmful gasses. And for chimneys, confirm that the flashing will be replaced for tear-offs, with new install of step and counter flashing.
The soffit, also known as eaves, are the underside of your roof that hangs off the side of your house, from the extension of the roof. Typically they are aluminum panels and can aid in venting your attic space. Venting through the soffit can help reduce moisture and protect your home in the attic.
