since i'm certainly no builder by trade, and have more or less been feeling my way through this day by day, it was necessary to hire out the upstairs addition as well as the shingling. i think i may have been able to figure out the shingles, but thought it better left to the pros, especially since half of the roof is a 12/12 pitch and the area over the addition needed a EDPM rubber roof due to the low slope (1/12).

here you can see the old front roof being cut off in sections to prep for the new master closet and bathroom. since the original attic roof peak wasn't all that high, the decision (on suggestion from the builder) was made to move the peak forward a foot, which also moved the peak up a foot since the roof was a 12/12 pitch. now the roof has an 8' ceiling and no longer feels like an attic...also, the sky trak was pretty sweet to watch in action but it made my yard look like i hosted a monster truck rally...not that i really care. (oh, and i got to drive it, which was really cool)

here the wall and roof framing are pretty much complete. you can make out the two 24 x 24 windows in the bathroom (which will be awning style) and the 36 x 12 window for the closet. in terms of access, you'll walk through the closet to get to the bathroom. all said, it adds about 200 square feet to the house, a 9'x10' closet and a 10'x11' bathroom. if all works as planned, it should be pretty nice. (as always, hopefully..)
new roof sheeting: at first i didn't plan on having the entire roof re-sheeted, but as is turned out, it made the new shingle application much easier and hopefully will make them last longer. originally it was 3/4" planks, now it's 1/2" OSB over the wood planks. basically its a brand new roof. and my house no longer leaks, which is the real benefit.
here the exterior sheeting is complete on the addition and the roof is done. now, i realize the front of the house doesn't look all that great, but envision is with a porch with roof between the addition and the first story. hopefully it all works out.. and if you need a builder in central michigan, i would highly recommend Buchanan Builders, i think they did a great job.
