- Had to make the same call last year—roof was 22 years old, asphalt shingles, Midwest winters.
- Decided on full tear-off after seeing a few curled shingles and some soft spots near the ridge.
- Decking was mostly okay, but a couple sheets had water damage.
- Insulation was surprisingly fine, just needed to patch a spot where there’d been a small leak.
- Contractor said adding a second layer would’ve trapped moisture and made things worse long term.
- Cost more upfront, but peace of mind’s worth it for me.
Full tear-off’s definitely the way I lean, especially if you’re thinking long-term. I get the temptation to just slap another layer on—cheaper, less mess—but in my experience, that’s just kicking the can down the road. Had a neighbor do the overlay thing and ended up with moldy decking two years later... not fun. Plus, if you ever want to upgrade to something greener (like solar shingles or a cool roof), you’ll need a clean slate anyway. Costs more now, but your future self will thank you.
I hear you on the full tear-off. I’ve seen too many “quick fixes” turn into bigger headaches, especially after a bad storm rolls through. One time, a client had two layers—looked fine from the street, but after a hailstorm, water found its way between the layers and just sat there. Ended up with rot and a much bigger bill. It’s tough to swallow the upfront cost, but you’re right—sometimes you gotta do it right the first time, even if your wallet protests.
“sometimes you gotta do it right the first time, even if your wallet protests.”
Yeah, that’s the hard truth. I used to think slapping a new layer on was a shortcut, but after tearing off a few roofs myself, I get why the pros push for full removal. Step one: strip it down and see what’s really going on underneath. Step two: fix any rot or soft spots—if you skip that, you’re just hiding problems. Step three: new underlayment, then shingles. It’s more work up front, but you skip the “surprise leaks” later. Your wallet might grumble, but your ceiling will thank you.
That’s exactly it—sometimes you just have to bite the bullet. I learned the hard way after adding a second layer on my old house. Looked fine for a couple years, then one winter we got ice damming and surprise, water started dripping in the guest room... Ended up costing more to fix because we had to rip off both layers and replace rotted decking. It’s tough on the budget, but catching those hidden issues early really does save headaches down the line.
