THe sheathing underneath was in pretty good shape for a house this old (1979), so we were happy not to have to cut any wood out. Except for the chimney hole of course. Here's a shot of Karren after the roof top chimney install. She can't get over that we did this ourselves. I don't have the heart to tell her that the homeowners probably will kill us on this if we ever have a fire! : (
So Monday I picked up the underlayment for the shingles, which had to be special ordered from Lowe's. Why does everything they order take so long to get to the store? I guess that's why Lowe's is known in the construction trades as "SLowe's." The under side of the chimney (inside) is framed in a black metal box to prevent contact with the combustibles and it serves as the chimney support in this cathedral ceiling application. Naturally these parts are sort of special as well. Lowe's sells ALMOST everything you need for this particular situation except a universal roof support, which I picked up in town after a day long search. Cal-Ranch stores had it, plus everything else you need for chimneys. Shoulda looked there first. There were several places that had the "additional"support but they wanted more than twice the price! It would be nice if Lowe's actually read the literature of the products they sell so they can stock the rest of the pieces that are REQUIRED for installation. Anyway, here's a look at the interior penetration:
It was a tight fit; I didn't want any air moving up past the box creating a draft. They drywall marks on the box just wiped off. Today I connected the rest of the stove pipe and the stove is ready for its initial burn. They are usually pretty stinky for 30 minutes or so, because of all the fresh metal having its surfaces heated and smoked up.
After fixing the stove in place I woke up Karren and we attacked the roof underlayment. We managed to get the stuff laid out square and completed the roof that was bare. It looks kind of cool. This stuff (Grace's Tri-flex synthetic) is very nice to work with and is really tough. It requires nails every four inches around the perimeter and every 24 in the field. Karren really liked it because they have little x's where you are supposed to nail. she likes that a lot! It sure does look better...
There is metal drip edge all the way around the roof. We noticed that the rake (angled edge to the right) had plywood edges that had weathered severely and I wanted to make sure that we never have to worry about that anymore. Here's the chimney after the storm collar was attached. Looks good!
We have to leave the lower part of the flashing loose because we'll slide shingles under it until half way past it, then they will ride over top of the flashing. This sheds the water correctly.
Stay tuned for the next installment: Critters that are in trouble or the Sky's the limit!
