Nearly Slipped Off a Steep Slate Roof During a Ridge Cap Install Today, FML

Been slinging slate for 8 years now and thought I had this pitch mastered, but up in Maine the wind kicked up something fierce while I was up on that 12/12 ridge cap. Was hammering in some new Malarkey cap shingles when my boot hit a patch of moss, and I slid a good 10 feet toward the edge before grabbing a rafter. Luckily my harness caught me, but damn, heart was pounding harder than my slate hammer. We're in Maine so every job site's got that extra slick from the damp, makes you double-check your grip every time. Anyone else had a close call on a steep install like that? I saw a post on r/Roofing about a guy who wasn't so lucky last month, SMH. Thinking of switching to more of those DeWalt harnesses with the auto-locking reels after this.

Hah, close calls are what separate the pros from the pretenders. I've taken a few headers on steep jobs myself, but screw the harness drama, real roofers balance like cats without 'em.
