That upfront cost is definitely intimidating, but your concerns make a lot of sense. When you say you’re worried about ventilation and long-term costs, are you thinking about ice dams or more about energy bills over time? I’ve noticed that a lot of folks in colder areas end up having to deal with rot or mold if they just keep layering. Did you get any quotes for both options? Sometimes the price difference isn’t as big as it first seems, especially if you’re already seeing issues with the old layers.
“I’ve noticed that a lot of folks in colder areas end up having to deal with rot or mold if they just keep layering.”
Yeah, this is what freaked me out too. Our inspector literally poked a finger through the old plywood under our shingles—like, horror movie stuff. I got quotes for both options and honestly, the “just add a layer” route was only a little cheaper. Once I pictured mold parties in my attic, I bit the bullet and did the full tear-off. My wallet cried, but at least my ceilings don’t drip anymore.
Finger-through-the-plywood is a classic, but not the kind of “soft touch” you want in a roof, right? I always ask folks—if you’re already seeing signs of rot or leaks, what’s that second layer really covering up? Sometimes it’s just putting a band-aid on a zombie. Sure, the upfront savings are tempting, but have you ever tried drying out attic insulation after a slow leak? Not fun... and the smell sticks around forever. Anyone else ever find weird stuff growing up there?

That’s exactly how I felt when I found a patch of black mold under the old shingles. I get wanting to save money upfront, but I ended up spending more replacing soaked insulation. Has anyone tried using a moisture meter before deciding? Wondering if that’s worth it.
I actually think a moisture meter can be helpful, but it’s not a magic bullet. Sometimes you’ll get a “dry” reading but there’s still hidden damage—especially with older roofs or if ventilation’s bad. I’ve seen spots that looked fine on the surface but had rot underneath once we pulled things up. For me, full removal is usually safer in humid climates, even if it’s pricier upfront. Otherwise, you risk missing stuff that ends up costing more down the line. Just my two cents...
