It’s kind of like sweeping dirt under the rug. You might not notice anything off for a while, but when you do, it’s usually a bigger headache than if you’d just started fresh.
That’s been my experience too—tried the “quick fix” with a second layer on my old ranch, and three years later I got to play detective with a mystery leak. Turns out, the original deck was already a bit wavy, so the new shingles just followed the rollercoaster. Lesson learned: sometimes paying for the full tear-off is just paying for less stress down the road. The Midwest freeze-thaw cycle doesn’t cut us any slack, either.
- Been there, done that—my last house had three layers hiding who-knows-what underneath. Looked fine until a raccoon found a soft spot and made himself at home.
- Midwest weather is brutal. One winter you’re fine, next spring you’re patching leaks and cursing ice dams.
- I get the temptation to just slap another layer on. Cheaper up front, less mess, and you can pretend everything’s solid...for a while.
- But man, once stuff starts going sideways (literally, in my case—the roofline started to sag), it’s a way bigger pain to fix.
- Only thing I’ll mildly disagree on: if your first layer is still pretty flat and you’re not planning to stay long-term, sometimes doubling up isn’t the end of the world. Just cross your fingers for no hidden rot.
- If I ever do this again, full tear-off for sure. Not worth the “surprise” repairs down the line—or the wildlife moving in.
I hear you on the raccoon squatters—nature’s little roof inspectors, right? Midwest weather’s a beast, and every extra shingle layer just traps more heat and moisture. Personally, I went full tear-off last time. Less landfill guilt, better insulation, and no “surprise” wildlife condos. Worth the mess, honestly.
I get the landfill guilt, but I’m honestly torn. My inspector said my old shingles were still solid, so I just did a second layer to save money. No raccoons (yet), and it was way less hassle. Maybe it’s not ideal for every roof, but it worked for me... at least for now.
I get wanting to save cash, but double-layering kinda freaks me out. My uncle did it and now his roof looks like a lumpy mattress. Plus, if you ever need repairs, finding leaks is a pain... not to mention the extra weight if you get heavy snow. Just my two cents.
