LESLIE: Luke in Illinois is on the line with a roofing question. What can we do for you?
LUKE: So I have gotten a few people to – estimates. I want to put steel roofing on my house. And one guy will tell me that I need to sheet it and the next guy will say that I can put it over the shingles. And I didn’t know what the standard process for that is. And now, I was also told by the same contractor, “Well, every few years, you have to replace the screws.” And that – I had never heard that before.
LESLIE: Yeah, that’s something we’ve never heard.
Now, when it comes to whether or not to remove the existing roof or shingles, I should say, before you go ahead and put on a metal roof – I mean in this instance, a metal roof is expensive. They’re very long-lasting, up to 50 years, and they’re beautiful. And I think the situation would be that you would want to remove the existing shingles, just to give yourself nice, smooth sheathing to go on top of – less weight on the roof, less heat being trapped and best usage of your money and use of the metal roof.
TOM: Luke, what kind of roof do you have now? Under the asphalt shingles, do you have solid sheathing?
LUKE: Only on part. I have a house that’s over, probably, 200 years old. And it has – what they did – I’d say a shifty contractor put tar paper over the – where the slats were for the shake.
TOM: Did you have original, wood, cedar shakes underneath that?
LUKE: No, it’s just – they just tore all the shake off and just put tar paper over it.
TOM: OK, look, the best thing for you to do here, as Leslie said, is to strip down to those rafters, re-sheathe the roof, then put the metal roof on top of that. Yeah, it’ll be less expensive to put the metal roof over the asphalt but you’re not going to get as clean or neat of a job.
And there’s really no point in adding to the way it’s been assembled right now, in kind of the inappropriate way it’s been assembled now, by sandwiching those shingles forever underneath that metal roof. I would take it completely down. And the guy that’s telling you to do that is, I think, giving you the best advice.
LUKE: Alright. Well, thank you very much for answering my questions.
TOM: You’re welcome, Luke. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
