Got a call from the in-laws saying that a large tree branch fell on the shed roof and put a half dollar sized hole in it.
Now in my salad days I think I looked a lot more like Bob Villa because I grew a dark beard -- but the similarities don't extend to talent. I did manage to build this shed many moons ago with my buddies and even put the shingles on more or less correctly.
I went over to do a quick patching job with a joist plate for underneath support, some aluminum flashing, and a handful of half-shingles that are at least 14.5 years into their 15 year lifespan.
I figured it's too cold already to lay shingles down and hope they'll seal, so I brought along a tube of roofing cement and a caulk gun. Turns out my "new" caulk gun was 1) used, and 2) broken by some nice customer at Lowes and then surreptitiously put back on the shelf.
Not wanting to return to the store, I cut the roof cement tube open with my utility knife and used a board end as a spatula to coat the underside of the shingles. It took 3 times as long and I got black gunk all over my hands. I glued down the flashing and then shingled over the hole.
The patch definitely looks like a patch, and I only had a few mostly-not-broken half shingles to work with. The best I can say is that at least nobody fell off the roof, critters can't get in, and that it probably won't leak.
I showed the picture of my poor patch job to the in-laws. They just said they won't be looking down on the roof any time soon, so they didn't care.
