My buddy is trying to determine the best way to roof the treehouse he is building. He is ready to start cutting the rafters, but he is not sure how
to deal with the trunks. You'll notice the issue immediately.
We have some ideas, but I don't want to influence anyone, so I'll keep them
to myself for now.
This question is mainly about rafter layout, not about sealing the roof
from rain, although suggestions/experience related to that are also welcome.

The smaller branches are not an issue, they will be cut. It's the 2 main
trunks that need to be dealt with. Based on the location of the trunks,
neither 16" OC or 24" OC will clear them.
Have fun!

Along the line of over kill(?), your "not sure it's needed" comment: The t=
runks to be boxed in, with the boxing members at 90=C2=B0. A diagonal brac=
ing, in the corners or in some fashion, would further prevent racking, if t=

I don't know tree house construction. Maybe my idea of a more rigid frami=

le, for when the trees move in the wind, etc. But I would think one needs=
to guard against too much racking, potential racking.

What it ended up being is a show of love from a father to his children.
Add a few pieces of furniture, some games and a sleeping bag or two and
it will be so much more than a "small storage room with a tree interrupting
the middle of it."
Sometimes we forget to see world through the eyes of a child. I try to
do it as often as I can. It makes the simple things in life so much fun.

I used one on my stand-alone play structure - bright blue 6 x 8 -
it would last about 4 years - so I replaced it 2 or 3 times in the
life of the structure - easy & cheap..

That was one the ideas we had.=20
The reason for the "preferred direction" and center ridge is because of the=
view. He is hoping=20
to have the gable face the house instead of a bunch of shingles.
After a few more responses, I'll ask a question about an idea we had to ret=

The house seems to be only about 10' X 10'. That's not so large that a st=

Overkill? Use some Simpson strong ties to further the joinings.

That is very close to what we had in mind, other than the "diagonal" rafter
between the trunks. Considered it, not sure it's needed.
The main idea was to "box" in each trunk with 2x6's and run a rafter from t=

Some thoughts:
Not sure just how he is to seal the inner tubes to the shingles and/or furt=
her roof topping. Might want to recommend, to him, to use spray adhesive,=
for auto head-liners (from your local auto parts store) or foam adhesive (=
from your local fabric shop).... the two spray glues are essentially the sa=
me. This adhesive may not seal the minute=20
"holes" as per from the shingle's small gravel, but it should allow good ad=
hesion of the inner tube to the shingles. They are for rubber products.
Spray on generously, allow to dry for a minute or two, then press the mater=
ials together. Clean up any residual glue (from hands and the like) with =
mineral spirits/paint thinner. This adhesive might be better than the shi=
ngle tacks, but doesn't hurt to use both. Probably $4 per can of spray, a=
t least 2 cans needed.
I'm kinna thinking tar won't stick to the rubber inner tubes, but I don't r=
eally know. The non-tar roofing sealant/adhesive might stick to the rubbe=
r tubes, maybe better than the spray adhesive. Might want to read the labe=
ls, to compare adhesion properties.

I'll wager that the tarp on your play structure looked more like this...
http://qaria.co/wp-content/uploads/2018/03/playset-tarp-heavy-swing-walmart.jpg
...than this:
https://i.imgur.com/UhTlqtO.jpg?1
My point is that there is not going to be any way to neatly - and tautly -
put a tarp over a 10' x 10' square structure that has a double trunk tree
coming up through the middle of it
Wind, rain, snow and gravity are sworn enemies of sloppy tarps.
I know you said "if it doesn't need to be weather-tight" but other than
building a large box around the tree and running the tarps in 4 directions,
leaving a huge hole in the middle, I don't see a way to use a tarp and have
it last. And if there is a hole the size of the 2 trunks in the roof, I don't
think it would be proper to call it a tree *house* anymore. ;-)

As I mentioned to my buddy last night: A couple of tarps would be pretty
easy to install. And easy to install again. And easy to install again. And
easy to install again. And easy to install again.

Well his skill set is growing along with the tree house. I've done decks and
walls, etc. so I've been coaching him a bit in that regard. He picked up a lot
of "treehouse" support structure skills from the company that he bought the
treehouse hardware from. He's a pretty smart guy in general.

That's basically where we were heading. Just looking for some other options
from the real experts.

So here is what my buddy ended up doing. He totally expects some leakage
down the tree trunk and will deal with it - or not - once the rest of the
tree house is done.
Boxed out trees, rafter layout:

Inner tubes used for seals, shingled roof.
Tar, etc. will strategically applied later

Exterior view so far- Funky look of siding is caused by coating of sawdust
which will be cleaned off.

I know that 20/20 hind sight is pretty common but it appears that this
is not so much of a tree house as a small storage room with a tree
interrupting the middle of it. Might have been just as effective and
easier if built close to the tree. Cool solution but I guess it became
an exercise in solving a problem vs. what it ended up being.

First thing that jumps out to me is a four sided hip roof and pyramid
hip roof.
All the rafters would terminate near the two trunks and you could get
creative with how it all joins together at the peak.

What's been done so far looks pretty legit, so I assumed the builder had
a decent skillset to begin with.
However, even with the preferred rafter direction, he could sandwich the
tree trunks and have a rafter going between the two. Then just block in
around them.
