Had a customer last year who went with a second layer to “save money”—then a hailstorm hit and the insurance barely covered anything because the old shingles underneath were already shot. Ended up costing more than a full tear-off would’ve in the first place. I get that budgets are tight, but shortcuts with roofs almost never pay off long term. Ventilation’s a big deal too—seen plenty of warped decking from trapped heat and moisture. If you’re already seeing leaks, I’d bite the bullet and do it right.
Yeah, I’ve seen that second-layer trick backfire more than once. Had a neighbor who thought he was being clever—stacked new shingles right on top of his 20-year-old ones. Next big storm, it looked like his roof had grown scales and insurance basically shrugged. I get wanting to save a few bucks, but roofs don’t really forgive shortcuts. And about ventilation—totally agree. I crawled up into an attic once and it felt like a sauna in July...decking was wavy as a potato chip. If you’re already patching leaks, might as well rip the bandaid off and do it right.

That’s where I landed too, even though my wallet wasn’t thrilled. I tried to stretch my old shingles for a couple extra years, but after a few “quick” repairs turned into weekend projects, it just wasn’t worth the stress. I did look at layering, but the warranty on new shingles gets weird if you don’t strip the old ones. Plus, in our humid summers, ventilation’s a must—my attic used to feel like a bread oven. Ended up biting the bullet and doing a full tear-off. Cost more upfront, but I sleep better when storms roll in now.
I get why you went for the full tear-off—peace of mind is worth a lot, especially with our weather. But I’ve seen some folks get a few decent years out of a second layer, if the decking’s still solid and you’re not dealing with major leaks or sagging. Did you notice any difference in noise or temperature after the tear-off? Sometimes people expect miracles and it’s only a slight change… curious how it felt for you.
To be honest, it depends on your location as well as how long you are staying. If you are exposed to hail, strong winds, or snowfall, I would pay a little more for a sturdier roof. However, if you are staying in a place with mild conditions or are staying for a short period of time, “good enough” could work for you.
