Yeah, that’s what worries me too—once you’ve got two or three layers up there, it’s like rolling the dice on what’s underneath. I get why people want to save money by just adding a new layer (I was tempted myself), but if there’s already some hidden rot or soft spots, wouldn’t that just make things worse down the line? I’m in central Illinois and our freeze-thaw cycles are brutal... I’d rather pay a bit more now than risk a big repair later. Anyone else find insurance companies push for full tear-offs these days?
I get the concern about hidden damage, especially with the Midwest weather doing its thing every winter. Still, I’m not totally convinced a full tear-off is always necessary. When we did our roof (asphalt shingles, 1,500 sq ft, pretty standard ranch), the contractor checked for soft spots and moisture with a thermal camera—turned out everything underneath was solid. We saved a chunk by just adding a second layer.
I know insurance companies lean toward full tear-offs now, probably to avoid long-term liability or claims down the road. But honestly, if your decking’s in good shape and you’re not already pushing the weight limit, an overlay isn’t always a shortcut to disaster. My neighbor’s place is going on year 12 with two layers—no leaks yet.
That said, if there’s any sign of rot or sagging, yeah, bite the bullet and tear it all off. But sometimes these blanket “always tear off” rules feel more like CYA for insurers than actual necessity... at least from what I’ve seen around here.

I’m with you on this. We did a second layer a few years back after getting the attic checked for leaks and mold—everything was dry. Saved us a couple grand, and the roof’s holding up fine so far. I get why insurance wants full tear-offs, but sometimes it just feels like overkill, especially when budgets are tight. Only thing I’d watch is resale—some buyers get spooked by two layers.

That’s the part that always trips folks up. I’ve seen houses sit longer on the market just because of that second layer, even if the roof’s solid. Around here, overlays are pretty common, but yeah, it can be a sticking point for picky buyers. Personally, I’ve done both—sometimes you just gotta work with what the budget allows.
I hear you—buyers can get weird about two layers, even when the roof’s in good shape. In my experience, it’s not always a dealbreaker, but it does come up during inspections. Sometimes folks just want that “clean slate” feeling with a full tear-off, especially if they’re worried about hidden issues or future repairs. But if the overlay was done right and there’s no sign of leaks or sagging, I usually reassure folks it’s not an automatic red flag. Budget’s real, and sometimes you just have to make the best call for your situation.
