Chalk lines definitely help, but I still swear by guide boards for hip and ridge shingles. I tried relying solely on chalk once, and halfway through realized my line had drifted slightly—ended up looking like a subtle curve from the ground. Not terrible, but enough to bug me every time I pulled into the driveway. Now I do both: chalk first, then boards for extra insurance. Might be overkill, but it keeps my perfectionist side happy...mostly.
Been there myself—thought I'd eyeball it once and ended up with a ridge that had a gentle wave... drove me nuts every time I mowed the lawn. Your chalk-and-board combo sounds solid, honestly. Might take a bit longer, but worth it for peace of mind.
I've done the chalk-and-board thing before, and yeah, it works... but honestly, sometimes it feels like overkill. Ever tried snapping a chalk line directly onto the shingles instead? I was skeptical at first, but found that if you take your time and keep tension on the line, you get a pretty clean guide without all the fuss of boards. Sure, there's a bit more room for error than with a rigid board, but it's way quicker and still beats eyeballing it by miles. Plus, no lumber to haul up and down the ladder. Curious if anyone else has given this method a shot or if I'm just cutting corners here...
I've tried snapping chalk lines straight onto shingles before, and honestly, it wasn't half bad. Sure, my first attempt looked like a drunk squirrel drew it, but once I got the hang of keeping the tension steady, it was pretty slick. Beats hauling lumber around any day. You ever have issues with the chalk washing off too quick though? Maybe I'm using cheap chalk, but a surprise drizzle had me guessing again...
I've snapped plenty of chalk lines straight onto shingles myself, and yeah, once you get the knack for it, it's a solid method. But honestly, the chalk washing off issue isn't just you or your cheap chalk—it's pretty common. Even the "good stuff" can vanish quick if there's unexpected rain or heavy dew overnight. Learned that the hard way when a quick afternoon shower turned my carefully marked lines into a guessing game the next morning... not fun.
Here's what I usually do: I switched to using red or blue chalk instead of white or yellow. Seems to stick around longer, especially if you grab the permanent marking chalk (usually labeled as "weather-resistant"). Just a heads-up though, that stuff doesn't come off easy, so make sure your lines are spot-on before snapping. Ask me how I know...
Another trick I've picked up is lightly spraying the chalk line with clear marking paint after snapping it. Just a quick misting—nothing heavy. It locks the chalk down nicely without making a mess. Sure, it's an extra step, but beats having to redo your layout after every drizzle.
Also, tension is key, like you mentioned. A buddy of mine used to snap lines so loose they looked like spaghetti noodles. Tightening up the line makes a huge difference in accuracy and how well the chalk transfers onto the shingles.
One last thing—if you're working solo, try anchoring one end of your chalk line with a nail or clamp. Saves you from doing the awkward one-handed shuffle trying to hold tension and snap at the same time. Been there, done that, got the crooked ridge lines to prove it.
Anyway, sounds like you're already getting the hang of it. Keep at it, and soon enough you'll be snapping lines like a pro—minus the drunk squirrel vibes.
