"These sprays just don't seem to handle expansion and contraction very well."
Yeah, that's generally true, but honestly I've seen some decent results when the spray sealant is applied in multiple thin layers instead of one thick coat. It seems counterintuitive, but layering it gradually allows for better flexibility during temperature swings. Still wouldn't rely on it long-term though—just might buy you a bit more time if you're stuck waiting for better weather...
I've messed around with those sprays a bit myself, and I agree they're not exactly miracle workers. Last winter, I tried the thin-layer trick mentioned earlier:
"layering it gradually allows for better flexibility during temperature swings."
It actually held up okay through a couple of freeze-thaw cycles. But honestly, once spring rolled around and things warmed up, cracks started reappearing anyway. Seems like temporary patching at best...good enough to limp through winter, but definitely not something I'd trust long-term.
I had pretty similar results with that layering method. Tried it on my garage roof a couple years back—got me through winter alright, but once the weather warmed up, it was back to square one. Honestly, these sprays and patches are decent for buying time, but eventually you've gotta bite the bullet and do a proper fix. Learned that lesson the hard way...
Yeah, that's what I'm worried about too—just bought my first place and the roof looks okay for now, but I'm guessing patches won't cut it long-term. Did you end up doing a full replacement or just major repairs? Curious how big of a project I'm looking at...
Honestly, a lot of folks jump straight to full replacements when sometimes major repairs can buy you years. Had a client last year who was convinced he needed a whole new roof—shingles looked worn, some leaks popping up—but after we took a closer look, turns out targeted repairs and better ventilation solved most of his issues. Saved him thousands, and he's good for at least another five years.
Not saying that's always the case...sometimes roofs are just too far gone. But before you commit to the big replacement, maybe get someone experienced to really inspect it thoroughly. You might be surprised how much life is left in it with some strategic fixes and regular maintenance. Just my two cents from seeing this scenario play out plenty of times.
