Each of the polygons making up the dome has interfaces with the adjoining polygons. Rake edge, drip edge, some kind of flashing, hip/ridge caps, nothing at all. I was reflecting on the one or two I have seen locally and in I could not recall what was used.Was the rest of your post not serious?
I get your points, but it was not IMO gobbleygook. It is a closer approximation to a sphere than a cube. Truncating a base and allowing for windows and doors and a sort of apron the comes down to the ground would certainly be part of the take off.. I would not expect the OP to bid the job directly off a few internet posts. My suggestions may or may not have helped the OP, but it would be an approach I would likely take.Tough crowd? Maybe, but you can't post gobbleygook on most forums and not get called out.
Anyway, you were right about the waste factor.
I know. I enjoyed your post about ice in the gutters so much that I didn't care you hadn't done an intro. You obviously know what you're talking about and I'm sure there is a lot I could learn from you (esp re: metal).I am not a smart-ass or a wise-guy. You will find most of my posts have substance and will be useful to the topic.
I could definitely use some work on my levity. Apologies and cheers.Further
Levity is is used with mixed results on the web. Aside from sticking in a winking smiley or a LOL here and there, one's intent can easily be misconstrued.
It's all good and I prefer to begin with mutual respect. Later, when there is a serious disagreement we can have a real pissin' match :laughing:I know.

Let's agree to disagree on the dome, but for the record I have done one. When you actually start roofing it, you realize each triangle took x shingles, and that you could fairly easily have estimated almost the exact number of bundles, even though the waste is ungodly. That mathematics agrees with this real world method is complete coincidence.

A tip for your next one. The manufacturer recommends dutch-lapping the hips. Do the flat bottmed ones first passing the hips 3", do the intersecting ones coming back over 3" again. This gives a 6" dutch lap.Run away? I'd love to have a dome job right about now :shifty:
We used a ton of coil stock too. Since there was no coping we flashed our hip shingles, and flashing a hip shingle takes a long pc of 'coping'.
