We have about 2250 sq.ft. of living space and just had ours replaced this past winter, I know winter isn't the
best time but we got loads of rain and a couple leaks, and they removed the old ones and replaced it for
$6300. We used Owens-Corning Architectural 30 year shingles and the put down new tar paper,
a drip edge(it never had one before) and an Owens-Corning Ridge Vent on every peak. We used
O-C Oakridge series in Desert Tan color:

They used this Ridge Vent:

The only regret we've had so far is I wish I paid extra for copper flashing as they used galvanized and it's
really shiny, it'll turn eventually but I think brown patina of copper would have looked better down the
road. We've several comments that the Desert Tan narrow tab shingle look like real wood.
The people that did ours have done a lot work for us here on the farm and are fully licensed contractors.
The guy is of Amish decent and has 12 kids, at one point they had some of the girls on the roof handing
out shingles in their long dresses and hair up in bun or whatever you call it. There's a lot fly-by-night
roofers out there so be careful. We also had a roof put on my late FIL house, the old farmhouse, and it
has a steep 12/12 pitch, now that was something to watch. The shingles on that one were over 30
years old but didn't look too bad but you could tell they were very brittle when they were taking them off.
I don't suggest leaving an old roof on, tear the old one off.
I'm just glad we finally found someone we can trust to get the job done, we've dealt with some real flakes in this area.
