NEED ADVICE ON REPLACING AN OLD LEAKY ROOF

Couldn’t agree more about checking the attic—people forget that’s where the real story is. I’d add, don’t just look for rot, but check insulation too. Wet insulation’s a mold magnet and kills your energy efficiency. Sometimes the “cheap fix” ends up costing double.

I get where you’re coming from about insulation, but I’d actually push back a little on the idea that it always needs to be replaced if it’s gotten wet. Sometimes, if you catch the leak early and the insulation’s just a bit damp—not soaked through—you can dry it out with fans and dehumidifiers. I’ve seen people rip everything out when a little patience would’ve saved them a chunk of cash.

That said, if there’s any sign of mold or that musty smell, yeah, it’s gotta go. But sometimes folks jump straight to demo mode when a careful inspection and some drying time could do the trick. Just my two cents from seeing a few too many overzealous “fixes” in older homes.

That’s a good point—people do tend to go straight for the sledgehammer when a little patience could do the trick. I’ve had a similar situation in my own place, actually. Had a slow drip from a flashing issue, and the insulation was just barely damp in one section. I set up a couple box fans and a dehumidifier for a few days, kept an eye (and nose) on it, and it dried out fine. No musty smell, no weird stains, nothing. Saved me a lot of hassle and money.

But I do wonder—how do you all decide when it’s “just damp” versus “too far gone”? Sometimes it’s hard to tell, especially with older insulation that already looks a little rough around the edges. I usually go by smell and feel, but I’ve heard some folks use moisture meters. Anyone tried that?

One thing I’d add is, if you’re going to try drying it out, make sure you pull back any vapor barriers or plastic sheeting so air can actually circulate. Otherwise you’re just trapping moisture in there. Also, if you’re dealing with blown-in cellulose, that stuff can clump up and hide wet spots, so it’s worth poking around a bit more thoroughly.

I get being cautious about mold, though. Once you get that musty smell or see any black spots, it’s game over for the insulation. No sense risking your health over a few bucks.

Curious if anyone’s had luck salvaging insulation after a bigger leak? Or is there a point where it’s just not worth the gamble? I’ve only dealt with minor stuff, so maybe I’m being too optimistic...

I’ve actually tried using a cheap moisture meter, and honestly, it’s been a game changer for figuring out what’s just damp versus what’s a lost cause. You don’t need anything fancy—just something that gives you a ballpark reading. If the insulation is reading high for more than a day or two, even with fans running, I’d say it’s probably not worth saving. Once that stuff gets saturated, especially old fiberglass or cellulose, it just never seems to bounce back right.

I’m with you on the mold risk—if there’s any doubt, I’d rather toss it than take chances with my lungs. That said, I’ve managed to salvage insulation after a pretty decent leak once, but only because I caught it quick and got airflow going right away. The second time, the water sat for a couple days before I noticed... at that point, it was clumpy, smelled weird, and just felt gross. Had to rip it all out.

Bottom line: if you have to think twice about whether it’s too far gone, it probably is. Peace of mind is worth more than saving a few bucks on insulation.

Totally get what you mean about the “is it worth saving?” debate. I’ve seen way too many people try to hang onto soggy insulation, thinking they’re being thrifty, and then end up with that weird musty smell that just never goes away. It’s like, you can paint the walls and buy all the candles you want, but if the insulation’s gone funky, your house is gonna smell like a wet basement forever.

I’m a big fan of the “when in doubt, throw it out” approach, especially with anything that’s been wet for more than a hot minute. Mold is sneaky and it doesn’t care how much you spent on that last roll of insulation. Plus, once you start opening things up, it’s kind of wild how much damage water can do behind the scenes. I had a client who thought it was just a little leak—turned out half the attic was basically a science experiment.

The only time I’ve seen someone successfully dry out insulation was when they caught the leak right away and had like four fans blasting 24/7. Even then, it was a gamble. Most of the time, it’s just not worth the risk or the hassle. And honestly, replacing insulation isn’t as bad as people think. It’s itchy and annoying, sure, but you get to pick something new that might even help with your energy bills. Silver lining?

Anyway, I’d say trust your nose and your gut. If it smells off or feels weird, it probably is. No sense risking your health over a few bucks. Plus, new insulation is kind of like a fresh start for your house... minus the confetti.
