Re: Stack Vent / 3 layers of shingles
I can't speak to the roof or any other issues you may have, but if you have decent DIY skills and the top layer of shingles is standard composition, extending the vent through the roof is a fairly easy job that would probably cost less than $20 for materials.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
