I’m looking for advice about how to shingle a round turet roof with architectural asphalt shingles. The roof is about 17′ outside diameter at the bottom and has a pitch of 11 in 12. My first issue is the drip edge – it doesn’t bend so I’m figuring I need to use something else otherwise I end up with hundreds of overalpped seams. As for the shingles, I can cut the starters and first row to match the curve, after that I think I can get away with 1/2 shingles cut pie-shaped, but I’m concerned that the pie cuts will leave an odd pattern of shingles such as thin bits. Anyone have experience? Would 3-tabs be better? Is there an easier way than cutting pie shaped pieces? I’ve got Owens Corning Oakridge Pro 30 shingles.

OK - here we go.
Drip edge- if you snip thru the roof flange, standard alum "D" style drip edge will make the radius you've got.
Shingles - before starting to shingle, snap a series of lines from the top of the turret to the eave. Space them every 18" at the eave to nothing at the top. Use your tape and measure up from the drip edge 11" and mark each verticle line.
Lay your first course with the ends butted to every other line. Measure off the top of the 1st course 5 1/2" and mark again. Alternate bond lines on the second course. You may need to trim a hair off each shingle. Go back to the 1st set of bond lines for the 3rd course. You will certainly need to trim each shingle in this course. Make your cuts with the angle of the bond lines. Continue alternating up the roof. Try to establish a control point at the top and occasionally check your coursing to see if you are gaining at the same rate all the way around.
Keep all your cut-offs. They'll be useful as you get higher. As the bond lines get closer together, you can start to use every third one and then every fourth.
A shingle shear would probably be worth the investment on this project - there's lot's of cutting to make it look right.

But you all knew that. I detailed it extensively in my blog.
i would second what seeyou said and add that i would take careful time to lay out so that i could cut everything on the ground. every turret i've ever roofed has been quite steep, usually 16 or more. if you are going to be doing any amount of roofing a shingle shark/shear is a no brainer and you should have no problem making your money back many times over.
Every day is a gift, that's why it's called the present.
that shark / shear tool
about how much & is it something they carry at rental houses?
Google "shingle shear"
$258.36 at Amazon.com
Maybe you should check with your local rental place.

yes I'll be checking
thanks, John
I've got a shingle rep named "John Harkins". I've never seen a shingle shear at a rental store, so it's doubtful. But I paid about $200 for mine 10 years ago. $239 sounds well worth it. I need new blades on mine.http://grantlogan.net/

Now they have the kit you can put together yourself, costs only $140 with shipping. Basically, you provide your own plywood base. Also, you have to order it from their factory.

Thanks for the info.
FWIW, I took a RAS to the blades for about 5 mins and it cuts as good as new.http://www.quittintime.com/ View Image
I figured you still had yours, mostly just bumbed this topic up for anyone else. I'm considering getting the kit, but not sure when I'll be on a roof again.
Does the kit seem to be the same thing, less the plywood? Just wondering if I'm better off getting the already build one.
Oh, and not to sound dum but what's an RAS? (stone of some sort?)

I'm hoping he meant an ROS.

I'm thinking he meant ROS--random orbit sander.

Mine's got a metal bed with a roof jack type hanger. We mostly use it on the ground to pre-cut, so the hanger seldom comes into play.
All the business parts seem to be the same.
One might be able to improve on the original making their own bed. I've kinda been scratching my head over that.
RAS= random Arbital sander, I guess. I meant ROS.http://www.quittintime.com/ View Image
I thought you wanted him to use a radial arm saw.
Where you 35 years ago when I and others shingled a 40' diam. geodesic dome? Each section was about 3' to a side. ;-) They can't get your Goat if you don't tell them where it is hidden.

Those geodesic domes are a different story. I've only seen one shingled that looked right. Who ever did this one should be commended. I'll take a picture the next time I'm out near it.http://grantlogan.net/

I will also see if I can get a pic of the one I worked on. It burned down many years ago so have to ask some old friends if anyone has a pic.
