Replacing A Roof Jack
On the boots if you have metal roof jacks with rubber boot seals on top with many models the rubber seals can be popped off and replaced without removing the metal part and there are also slip over boots that can just nestle down over the existing damaged boot and overlap the top of the jack but contractor would have to look at it and see then go get parts so if using a contractor probably cheaper to just have him bring new ones right off unless quite close to his supply wholesaler.
