Charlie: Paul in southwest says, “I put a new roof on, and the contractor installed the” … I love what he puts here. “twirly bird vents, in addition to ridge vents. Should I have these removed? It’s an old 1966 two story house, has about three to four degrees hotter upstairs with the continuous soffit vents.” I’m not sure that the heat upstairs has anything to do with his twirly birds does it?
Podcast: Play in new window
Tom: No. It has nothing to do with it. Why the contractor did that is because he doesn’t know what he’s doing. He’s just going through the motions. There’s an old saying, a guy will tell you he’s been in the business for 30 years. Well, he’s been in the business one year, thirty times.
Charlie: Right. It’s the same thing when you go scuba diving.
Tom: Nice. So nice.
Charlie: Seriously. No, seriously. When you’re on the dock, the dive master will always ask you have many dives? How many dives? The people who give a reasonable number, like 18 dives, 30 dives, whatever, those guys are in. It’s the ones who say “Oh, I’ve been on hundreds of dives.”, that’s the guy you’ve got to watch when you get down there.
Tom: That’s true, but some people like, say, Jim at Ideal Roofing, they stay educated about the newer things that need to be done. Would I spend the money to take them off? I’m not going to tell him he has to. Would it be better not to have them? Yes. I’ll let them make that decision, but as far as that goes, it’s just a redundancy that probably does more harm than good because it’s short circuiting the system from drawing from the bottom and exhausting at the top.
Charlie: Mm-hmm (affirmative).
