D&M Home Inspections

A sewer pipe vents sewer/methane gas from the septic tank or sewer through the roof. A flashing must be installed around the pipe to keep it from leaking. A standard flashing will be made of aluminum with a rubber collar. Sometimes the collar will split. At this point some people elect to add a little tar to the flashing to keep it from leaking. This is a temporary fix only until the flashing can be replaced.

The photo is standard sewer vent pipe flashing. Flashing should not be face nailed and left exposed to the elements.
