Roof, replace plumbing vnt stack boots question
My adult son has a 8 year old home and the pvc vent pipe penetrations in the roof leak around the pipe where it goes through the boot.
Is there a cure for this (like sliding another boot over the present one or is it normal to replace the whole roof "jack"- which is a lot more work for an only 8 year old house.
house is 2 story on a high foundation so he can not do it himself, but wants to know what the usual repair method is.
