YES...but not for each individual row of shingles. Standard 4' rolls, I was just rolling out the paper as I went up. It was good for a few rows. Just made it easier to do it that way. They recommend going over an existing asphalt roof. You just have to use 40# felt paper to provide a clean smooth surface for the metal shingles.
Block work took about 3 days and another day to fill. I can't say it has been particularly cheap but I found it to be reasonable block was specified by my architect. Perhaps we could have done poured walls. I'll have to investigate that for next time ( the barn or cidery)
Our electric service lines have been dug in and run to a location about 70 yds from the house. They did a very nice job but it tore the road up pretty good. The reason I only put #3 rock down was because I knew a lot of large trucks would be making the trip up and down and pounding it into the road and that would give us a solid road base to smooth out and then cover with crusher run. I'm glad I went that route because I'd be upset if I had done the final topcoat only to have it rutted up and covered with dirt. I have to say I am very happy to have the service box up here.
The walls were filled and the anchor screws were set. 102 of them. That's a lot of holes to drill for the sill plates. I began laying out the plumbing for waste connections and ended up spending all of today changing the layout of the bathroom on the fly. I needed more room space for my boiler room. Wife and I came up with a layout that she likes and will give us the space we need. It requires me to move one three foot wall and reposition some drains.
