My parents built a cabin in Union County in 1984. My father passed away in 1987 and the cabin was turned over to my generation. Otherwise, I probably would never have been part-owner of a cabin. But since it turned out that way, we've been going every spring with my sisters to do the annual spring cleanup and maintenance work.
The biggest job this year was washing the roof. We've done it several times over the years but this year we thought we'd make it easy with a 1000 gal. tank of water and a high pressure washer. That was a wishy washy idea! It was eight years since it was last washed and the black stuff was stuck on tight. The only way to get it off was to blast it off at close range with the pressure washer. That meant doing only a small section at a time and it was slow going.
By the time this side was finished we saw it's going to get dark before the job was done. But two dedicated people were determined to finish. Leroy set up a big spotlight and they continued to work (in the rain) after dark.
At 10 p.m. the water ran out and they finally quit. It was all done except one small section about 3 ft. across and half way down this back side of the roof.
It needs to be painted and now, while it is clean, is the time to do it. But we agreed to hire someone to do it. Washing it was enough for a bunch of (mostly) senior citizens.
