Lets say, hypothetically, that I'm going to build a 25 foot tall wizard tower in the woods.
The building is octagonal, which means there will be 8 ridge caps intersecting at the peak of the metal roof. The roof is 18/12 so it'll be a pretty big area where the ridge caps intersect. How the hell do I cap or seal that? I have everything else figured out (aside from permits but this is another step in that direction)
I don't even know how to research this sort of thing which is why I ask
Overhang it and make eaves? Why does it need to be airtight? What dark machinations are you doing?
>airtight
I just need the very tip to be shielded from rain. I'm not sure how to acquire or attach some type of roof cap.
>What dark machinations are you doing?
It's basically just going to be an office. My wife is letting me build it in hopes that I stop trying to do similarly absurd things in our actual house
Sheet of copper or tin cut and folded into a cone then nailed to the top. Possibly a bit of brazing to seal the tip and some overlap in the folding to make it watertight.
>My wife is letting me build it in hopes that I stop trying to do similarly absurd things in our actual house
I'm building a similar tower in a year or two on the hilltop in my woods for similar reasons; considering starting with a two-tier gazebo type thing and closing it in later if I like it well enough. It seems polite to ask her opinion before I visibly modify the house or anything adjacent to her gardens but innawoods I just do whatever.
Couldn't you just make a solid tip from a mold, then put it on top of a truncated octagonal pyramid? The tip wouldn't have to be very big, and you probably wouldn't notice it from afar
I scrubbed through this video on mute for a bit and I think there's a chance it could be useful.

Check out Guédelon Castle, it’s a French giga larp project where they’re making a castle from scratch with period tools.
It’s got some handy shit that could help you
I'm not larping, this is all cinder blocks and standing seam. Its basically the same as a shed as far as materials goes, just a weird shape.
Forgetting the "tower" aspect, how do I cap an 8 sided metal roof?
Neither are they, anon is moronic. It’s a real castle.
Yeah I knew about it already, that's not at all what I'm building
Are you telling me the peak of a roof can be silicone? Did you misread something or am I just not following what you're saying
silicone from a caulking gun you notools moron.
did you really need to ask here and not just google it in the first place?
Cut this shape out of a flat sheet of steel, where the radius is how far you want the cap to go down
For an 18/12 roof that doesn't have to be very long
Bend each line a bit at a time until the first and last faces overlap as perfectly as possible, then spot weld / epoxy them together
You'll need something to seal the tip, then paint the hell out of it. Maybe do a mockup with cardboard first
Holy shit thanks anon. Didn't know it was something I could actually make.
>You'll need something to seal the tip
Like silicone or some other piece of metal or what?
I mean, you could probably buy an artisan one online but this is diy after all
Since it'll barely be visible I would use a galvanized / hot dipped / whatever screw / nail and epoxy it into the tip
Keep in mind if you cut / bend pre-painted sheet metal it can ruin the coating, so you'll definitely want to research and prep for a final coating on whatever you make
Also this is what the software says for a mathematically perfect 18:12 octagon pyramid, your actual roof may vary a little.
Awesome, this is perfect. Thanks for the info man
No problem, hope it goes well
you could just do another smaller one and stagger the seams (e.g. spin it 180º)
just hammer some lead over the top fa.m
Pic is my actual plan so far by the way. 25' tall, 8' at the widest inside, with the width of the 8 internal walls being about 40". The door starts high because of the water table. There will be a staircase there. The arched doorway and window frames will be custom cast stone that I'm 3d printing the molds for. Technically it is 2 stories but it will be uncomfortable to stand on the second floor which is fine because that's where the desk will be. I'm building everything to code.
8' diameter is pretty tight. My house is french country / french provincial and I have an octagonal turret. I went 11' diameter and it's a good size for a cozy study but emphasis on cozy, I would have gone a little bigger if I did it all again. 8' will feel like a closet or a bathroom.
>I would have gone a little bigger if I did it all again.
How big?
Maybe just 12' or 12'6", too wide and the proportions are off... but with furniture in there the feel of the space starts to close in quicker than you'd think.
Much obliged. Adding to my document
>two-tier gazebo type thing
That sounds awesome and I hope to see it here someday
15 seconds in google. Just cut and solder a cone and slap it on top.
Blast
really? just use a cone for the cap...how moronic can you be to not realize that! i have an extra chromosome and it took me 10 seconds
roofing doesn't lay on a radius as well as a flat
also, wasted quads
you just connect the roof with whatever polygon you want. they don't have to connect perfectly at the top. you cap the whole with a flat piece, and flash over the whole thing with a small cone that you would barely see from the ground.
You may be able to find something pre-made.
Good search terms:
gazebo cap flashing
gazebo roof cap
turret cap flashing
octagonal roof cap
These guys have a selection.

Make sure you use a compatible metal since some metals left in-contact will have galvanic corrosion.
Why cap it…4 drops ofvrain aint shit
>How the hell do I cap or seal that?
try copper finials or spires
Dont try anything because you’re obviously full of shit
