Generally, this collar consists of a rubber boot and metal plate, which is typically made from aluminum that is being built into the collar’s top.
The use of a roof vent pipe collar is to give a tight seal to prevent debris and rain from entering the attic. Gradually, the rubber boot may split up due to the harsh weather or sun exposure.
A damaged pipe collar will first enable the rainwater to pool around and then getting into the home’s interior walls, causing considerable damage.
