How Do I Finish The Peak?


All the shakes are on the cupola except for whatever I'm going to do at the peak. I was thinking of a mini cupola and raising the peak up a bit or making an octagonal cap with 1x8 cedar and gluing that together and using some type of roof cement to secure it.

I was also thinking of forming up a piece of copper like the flashing I made but, like the flashing in the photo, I have no idea how to secure it without piercing it with nails. If you look at what's underneath, creating any holes for water to get through doesn't seem like a good idea.

Here is what I've done so far:

This is the top of the cupola. If I were to add some sort of nailing block for the cap, I'd have to cut away the shakes.


View from the side.


This is the flashing I made for the cap. It is not yet secured.



I'm at a loss as to how to properly finish this. I was going to finish it with shakes but I'd be doing a lot of nailing but... more places for rain to seep through. I have no idea how to finish this.

Any help and/or ideas?
Thanks, Julie

Is the felt 2" or more under that cap? Almost looks as if the field shakes could have been one row higher.

As for the cap, on each side nail a doubled over piece of aluminum 4-6" long, the same color as the cap about 2" up the roof. The piece should be about 1/2 wide and match the cap in color. Place the cap, and and fold the strips of aluminum back against the cap and about 45 degrees over 90. Cut all of them off leaving about 1/2" -3/4" of the strips. Then, just finish dressing them down over the edge of the cap.

Put your cap under new ridge cap pieces that are precisely cut to come to the top.
Put no nails into this spot. they need to be long enough that the nails below the metal cap hold them in place.
Also your felt or tin underneath should lap in with the shingles and cover the top.

Your cap is nice, but i'd like it even more if it were copper.

If the underside can not be seen then I might think about using the copper as you mentioned before and soldering a length of all-thread to the inside of the peak of the cover, then drill through the top of the roof and attach with a double nut or something akin to that from underneath.

The felt is right at 2" under the cap. There's probably four layers of felt at that point.

All the shakes have 7-1/2" exposure, including the ridges. There's 15-1/2" from the center to the bottom edge of the existing ridge shakes. That would mean I'd have to make a cap with a 16" diameter to keep that 7-1/2" exposure.

The only issue I see with doing what you showed in your photo is the piece I made needs to be held down at the center as it now springs up. If I took some of the bend out of the joints I may have to install a lot of those clip-strips. I'll play around with it some more.

I'm being pressured here at home to make a finial cap. I'm so burned out on this roof I just want to walk away from it. I still have to do the roof on the gazebo and after all the time it took to do the cupola, I'm not anxious to do that.

I finally made a decision. Take the flashing, cut shakes to fit the sections and screw them to the flashing from the bottom.




Now the 7-1/2" exposure continues on up the ridge. When I'm ready to install it on the main roof, I'll permanently affix the finial and that will hold down the shake/flashing. I'm going to toy with a larger flashing on the underside of the finial and see how it looks. As it is, it just barely covers the shake top edge.
