Treehouse roof flashing.
You should never use a flat roof for a treehouse.
A properly sloped or pitched roof is much superior.
The ideal roof is impervious to water but also needs to rapidly shed water so there is no chance of pools or damp patches building up.
The first decision we made when it came to the roof was how tall you want your treehouse.
It is too high for me to reach the roof from a ladder on the ground.
If your design calls for a flat roof try to introduce even a small slope of 3 5 so water cannot sit there.
Top off the tree just below the roof line and build a solid roof above.
The first is a bit dramatic.
Roof pitch can be a bit confusing but i will tell you how we did it and please know that you can modify to what suits your treehouse best.
Tire tubes are a good source of rubber a flexible membrane for fashioning a pipe collar like boot around a trunk that passes through your tree house roof.
Also there is an open deck in the front so the building is actually six sided.
The base is eight sided but stretched a bit.

The second solution is to build a wall vapor barrier around the trunk on the inside of the treehouse.
Please carefully cut the tire with a sharp knife and each tube will yield two rings of rubber with a natural curve to them that will prove useful when wrapping it around a tree trunk.
The tree isn t in the exact center.
I built a treehouse last summer 17 x 14 platform with a deck it had to be done before my wedding day honeymoon suite consequentially we were hurrying when we shingled the roof and we didn t quite get the flashing right around the two branches that go through the roof.
I have seen a treehouse built in four cedars designed this way and it works remarkably well however it is not practical for most applications.
