I have a home built in 1976. Recently while on the roof, I noticed the roof vent pipe boot has deteriorated.
I went to Lowes, Home Depot, and 3 other local hardware stores looking for a boot to fit my pipe – 4.5 inches OD. It seems there is none for this size and they only go to 4".
Any suggestions of where I can find one or what I can do to remedy the problem.
