Mold Caused By Roof Leak
TOM IN MICHIGAN: I was just wondering, I’ve got a roof leak or had a roof leak. Once the roof leak stopped, I’ve got what looks like mold on the boards and in the rafters?
TOM IN MICHIGAN: What can be done about that other than just tearing all the wood out and replacing it all?
TOM: You don’t have to get too emotional about this. If you get a leak and you get some mold or some algae growth on the underside of the plywood, the thing is that once you’ve taken the moisture away from this, it’s not going to get any further; it’s not going to decay any further.
And so as long as it’s not rotted now, the fact that you’ve got a little bit of mold stain there, I wouldn’t worry too much about it. If it’ll make you feel better, you could mix up a bleach-and-water solution, put it in a plant sprayer – like a pump-up sprayer – and just saturate those areas that look moldy. That will kill anything that’s left behind. But I would definitely not tear things out just because it got a little moldy because of the roof leak. That’s pretty common, actually.
TOM IN MICHIGAN: Alright. I appreciate it.
