gazebo roof

I've shingled an octagon gazebo roof and am having a heck of a time finishing at the top where the cone comes together. Can anyone help?

Picture working toward the right, or counterclockwise as you look down on the roof- Once the pieces of ridge cap get close to the top and they begin to overlap each other, it works well to trim the cap shingles so that they are more pie shaped- not as long on the top. Nail one shingle down, folding it over the adjacent sides that it overlaps and nailing the upper corners. The next piece can get trimmed on the left along the left ridge line so that it bisects the two ridges exactly (you may put roof tar under it if desired), while the right side can fold onto the adjacent sides and get nailed down. The right side of the cap really does not need to be any longer than the ridge, since it is getting overlapped by the next piece, so just trim them with a hook blade as you go along. Repeat this as you go around the octagon. Your 8th shingle will be a triangle.

Once that's done, the only leak is at the top and a piece of sheet metal bent over the top will work nicely to cap it. You can also look into purchasing octagon finials.

This part is wrong and didn't come out of my brain right. It was bugging me all day at work. As the caps get near the top, The top edges of the first shingle on that row would get bent over the ridge, and folded down on the adjacent left and right sides. Anything that wants to fold onto more than the 3 sides could be cut off.

The next shingles you lay will be put down in order, like holding 7 more playing cards in your hand. You'll trim the peaks of each of them even with the hip on the left and right. Each piece of ridge cap covers one ridge, the rest is cut off. Otherwise you build it up too thick.

Once you're close enough to the top that you don't need more shingles, put on your homemade sheet metal finial, or purchase one!
