Roof work now going on

OK, to understand all this a bit of background on the building is needed.

It's a big square flat topped box. There is interior roof access, if one calls a hatchway accessed by leaning a ladder precariously from the stairs access. Earlier this year we had Bill install a slightly lowered ceiling area at the top of the stairs, with a pulldown attic ladder, making access to the roof quite easy, unless you just have a thing about heights, like myself. The pulldown ladder made it real easy for contractors to get to the roof to make bids, and the workers are finding it super handy, they still have some exterior ladders for hauling up materials but other than that they use the interior ladder 'cause it makes it so much easier. The reason I'd pushed for the ladder install was that otherwise we'd not be able to see what the roof was like, and it had been decades since anything had been done up there.

So yesterday they started on the job, first scraping off the old roofing material so they could see what the roof proper was like, which turned out to be not absolutely awful, but there is some rot, and the surface is rather uneven, more so than works with the roofing material we're having installed. So they're fixing the rotten sections, and then installing 1/2" CDX Plywood over the lot, and then back to the regularly scheduled roofing project. Adds $2295.00 to the cost, which is reasonable, at least to me. And these chaps are good steady workers; it's right above my head, I can tell they are working steadily, trust me on this!
