I've noticed battery performance in cold weather has improved quite a bit recently. Lithium-ion tech is way better at handling freezing temps than the older NiCad stuff. But still, if you're out there for hours, the charge definitely drops quicker than normal—keeping a spare battery warm in your jacket pocket helps a lot. Honestly though, air nailers still feel like the safer bet on those extra chilly mornings... ever had your compressor lines freeze up on you? That's a whole other headache...
Had compressor lines freeze up on me more times than I care to remember—usually at the worst possible moment, too. Last winter, we were doing emergency repairs after a storm, and the lines froze solid halfway through. Ended up switching to battery-powered nailers just to finish the job. Lithium-ion batteries definitely handle cold better now, but still not perfect. Keeping spares warm helps, but for extended cold-weather roofing jobs, air nailers still edge them out reliability-wise... provided you keep an eye on moisture buildup in your compressor lines.
Totally agree about keeping moisture out of your compressor lines—been there myself more times than I'd like. One thing that's helped me is installing an inline air dryer and regularly draining the tank, especially before a cold snap hits. Battery nailers are handy, no doubt, but I've found if you're meticulous with compressor maintenance—draining daily and using antifreeze additives—you'll rarely get caught out, even on those brutal winter jobs. Just my two cents from way too many freezing rooftop mornings...
Have you ever had your compressor freeze up mid-job though? Happened to me last winter—tank drained, lines dry (or so I thought), but still ended up with ice crystals clogging the fittings. Maybe I wasn't thorough enough with the antifreeze additive... Battery nailers might not have the same punch, but man, they're tempting after mornings like that. Any tips on making sure the antifreeze actually gets everywhere it needs to go?
Had a similar issue last January—thought I'd covered everything, but ice still clogged the couplers halfway through. Found out later that cycling the antifreeze through the lines multiple times helps ensure full coverage. Tedious, yeah...but beats freezing your fingers off troubleshooting mid-job.
