Eyeballing it got me in trouble too—first ridge I ever did looked fine up close, but once I stepped back, it was way off. My trick now is snapping a chalk line on both sides of the ridge and checking it from the ground before I start nailing anything down. Saved me a ton of rework, especially on older roofs where nothing’s actually straight. I’ve tried those pre-bent ridge caps, but honestly, they didn’t flex enough for my wonky roofline. Just taking it slow and double-checking alignment as I go made all the difference for me.
Chalk lines are a lifesaver, honestly. I learned the hard way too—first time I tried just “following the ridge,” it looked like a snake from the driveway. I do a dry lay with a few shingles before nailing, just to see how things line up. Pre-bent caps never quite sat right for me either, especially on those old farmhouses where nothing’s square. Sometimes I’ll even use a level if the ridge is really weird, just to double check.
Chalk lines are a must, but even then, I’ve seen ridges that just wander no matter what you do. On older roofs, sometimes I’ll snap two lines—one each side of the ridge—just to keep things looking straight from the ground. Pre-bent caps never fit right for me either, especially after a storm when nothing’s square anymore. Sometimes you gotta just trust your eye and tweak as you go.

That’s pretty much what I ended up doing on my last roof job. My house is older, and after a couple storms, nothing lines up like it should. Chalk lines help, but I still get spots where the ridge cap just looks off from the yard. I’ve tried those pre-bent caps too—never seem to sit right, especially if the decking’s a bit warped. Has anyone found a brand or style that actually fits well on uneven ridges? Or is it just always a bit of a compromise on these older roofs?

Yeah, that’s just the reality with older roofs. I’ve tried a bunch of different ridge caps—none of them really hide a wavy deck. Sometimes I’ll hand-bend the caps a bit more to match the shape, but it’s always a compromise. Honestly, I think it comes down to making it look as straight as possible from the ground and not stressing about perfection. Pre-bent ones are never a perfect fit if your ridge is uneven.
