Some of the siding on the RV Garage was failing. It was in the gable over the greenhouse, and I didn’t see a good way to get up there to work on it without damaging the greenhouse. The contractors we called had to give it some thought. One wanted to build a new post inside the greenhouse to support the roof, then rest a scaffold on top. Another planned to use some construction machinery, like a giant forklift, to position their workers just above the greenhouse roof while they worked on the siding. One never called back.
and after the work was finished:
We got it done (barely) before winter!
