Well I just had my plumbing inspection on my kitchen and it turns out my sink vent pipe needs to be moved as it's to close to my upstairs window. I will be having the plumber move it this week and he said he will cap the pipe so it won't leak until I repair the hole. Can anyone let me know what steps I need to take to repair where the old hole is? My kitchen is open in the ceiling right now so I can see where the rafters run. I just don't know the first thing about repairing roofs so any help would be great. Also if you think it might be above me, what should I expect to pay to get this repaired?
