Took advantage of a gorgeous mid-January day, sunny, dry, and not too chilly, to finally replace the cracked shower skylight on the RV roof. The old one developed a large crack (probably from a tree branch), and the plastic started to craze badly. Wasn’t thrilled with that dark-tinted model anyway.
This new white one feels way thicker and more solid, no more flex when you push on it. I carefully cut around the old tape, pried the cracked skylight off, cleaned everything up, and laid fresh strips of super-sticky Alpha Systems butyl tape around the opening for a good seal.
Screwed the new one down with fresh screws, then ran a nice bead of self-leveling lap sealant all around the edges and over every screw head. Didn’t bother with roofing tape today since it’s not quite warm enough for it to stick well, but the sealant should hold us fine, especially with a couple more sunny days coming to allow it to cure before the rain returns.
The roof is looking good overall; I’m planning to order another pail of that Alpha Systems acrylic coating and slap on a fresh coat in spring to keep everything sealed and bright white.
