Treehouse roof around tree.
The roof will extend the life of the tree house and is just as important as the rest of the framing.
A flat roof is the easiest to install and when built correctly is easy to maintain.
Don t restrict tree growth.
Try to to drill the pilot holes as straight and level as possible.
The top set of beams will be the floor height of your treehouse.
You should never use a flat roof for a treehouse.
Once the frame is square install your floor joist.
Add spacers between the beams and the tree to allow movement.
Follow the simple steps below to frame your own tree house roof.
When designing a treehouse in a single tree it is often necessary to pass the trunk and or major branches through the walls or roof of the structure to maximize space and achieve weight balance.
Lag two sets of beams to the tree using a 3 4 diameter x 10 lag screw.

These two boards will serve as a support beam for the rest of the structure.
The down side as you point out is that it is nearly impossible to seal the water from entering through these exit points.
Next install the perimeter beams to the top set o beams and square them up using the 3 4 5 rule.
Leave gaps around the tree.
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 treehouse was in a very very large oak tree.
It had a gravity fed cistern from rain water for a water system and a wood stove.
A properly sloped or pitched roof is much superior.
To accommodate tree movement and growth allow gaps around any branches or trunks that penetrate the tree house.
This can strangle the tree.
If your design calls for a flat roof try to introduce even a small slope of 3 5 so water cannot sit there.
The roof s primary role is of protection and so it is a good place to get right.
Use extra long large bolts.
Be sure the tree is at least 12 inches in diameter.
It was almost something out of a beatrix potter book.
