Ok, some pictures. Once again, I finished in the rain last night, and it has been raining all day. And rain in the forecast for the weekend.
Starting on the ground: Pic 01, stairway to heaven. Pic 02, the belt to keep me from winding up there (or the other place).

The roof was in bad shape when the windstorm finished it off. Here's a small section of what is now under all that roofing paper. As you can see, the previously exposed section of the three tab shingles is gone. Don't you just love the cute little staples holding down the back part of the shingle?

The procedure for this kind of roofing is to cut several sections, nine inches wide, and nail them to the edge of the roof, in the area that will be covered by the roll roofing. These small sections are very securely nailed to the roof. The instructions call for two rows of nails, one inch in from the edges, spaced four inches apart. I generously overlapped these edge strips. This is the surface that will receive the asphalt roofing cement.

As I'm making my way around the edge of the roof, in addition to not falling off, I have to make sure I've covered all the territory. The long straight edges of the ridge and the drip edge and the rake were pretty easy, but the section around the chimney required some fiddling. Also complicating this section was a small valley.

The valley needs more reinforcement because it will carry much more water in a given area.

On Sunday, I cleaned the roof thoroughly, and we got the paper nailed down. Monday, Tuesday and Wednesday after work, say, 6 pm to 9 pm each night, was spent cutting and nailing the edge strips. Thursday night, I got to actually cover some roof with the roll material. I measured it out so that it started on the west eave and extended across the valley to the east. This was about 26 feet. I unrolled a new roll on the grass, measured it and cut it. I rerolled it and carried it to the roof. After a false start as to which way to position the roll (it does have an up and down edge in addition to the obvious top and bottom surface), I decided to save myself the trouble of throwing it down, climbing down, reversing the roll direction, and carrying it back up again just so I could start at the eave edge. So, I took a guess, and started the roll at the valley and unrolled toward the western eave.
My guess was pretty good. I was short by two inches. Good guess, but that meant that I now had a fifty pound 3x26 foot sheet of flexible material I needed to push/pull two inches to the west. And ZERO inches to the south--DOWNHILL. After some fiddlefartin around, I got it in place. The upper selvage edge is now secure, but the lower edge is free floating. I haven't applied the cement yet. I am thinking about waiting to have all the strips in place before I apply any cement. I will also measure more carefully for the next rolls as I move uphill. It's 14 feet from the top edge of that bottom roll to the ridge. I think I'll make that seven two foot exposures, with a generous one foot overlap. That means I need to go get two more rolls from the store though. Forecast for the weekend: Rain. Pic 01: Starting from the valley, guessing how far the roll will extend. Pic 02: Pretty good guess, within 2". In this picture, it's all nailed down after being adjusted westward. I didn't take any pictures of the adjustment work. I'm just thankful to be alive. It was a handful.

Not actually pictures of the roof, but pictures of the roof. The weather that makes the scary dangerous rain does make for pretty skies and pretty sunsets.

no. I am not handy. On your scale, I'd probably be a minus-5--total klutz.
And I've tried. Repeatedly. I can read and follow instructions, no problem, but I don't have that instinctive handiness that some people have. But I'm crafty and creative, so I just go with my strengths and pay people to do what I can't or won't do. Like clean.

I'm trying to figure out why you nail down a shitload of pieces, along the straight edges, instead of using a 9 inch wide strip? It would be a hell of a lot easier to cut 9 inches off the end of a roll, plus no seams/joints.

Are you talking about the valley reinforcement? The overlapping pieces make it stronger, where the run-off is heaviest. The seams are okay, since they go downward with the water flow.

No, I'm talking about the edges. There is no reason that couldn't be a 9 inch wide strip.

I think I see what you're saying...except that trying to nail down a long strip like that would be a pain. You'd have to make sure it stays straight along the edge as you go. The asphalt will cover the seams of the pieces.

It's easier to align if it's in smaller pieces!
C'mon, you build stuff--you know it's true. |

No it is not. You can't tell me it's easier to align a dozen short pieces of anything than one long one. Without a chalk line or string line it's not going to be straight anyway. The strip going on top is one piece which will make any unevenness is the bottom course look like shit.
