Hi - would really appreciate your advice. Is the repair to the pipe vent on my roof OK? The roofer said there was a rip in the rubber boot on the ridge side that was letting a small amount of water in. So he used a stretch of lead to form a collar and sealed it in place with silicone sealant, covering the rip. My concern is that the rubber boot will fail on the other side, particularly now it's carrying a lead collar. The scaffolding is costing me a fortune (it's a townhouse) so I don't want to have to do this again. Should I trust the roofer's expertise and relax that all is now well? Or should I ask them to replace the rubber boot entirely? Thanks for your help...
