Aim for a slope of at least 30 but preferably 45 or more.
Flat roof treehouse.
To waterproof a sloped roof you can attach felt over a thin plywood base and cover it with shingles or boards.
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 of the treehouse was pretty standard framing and once completed we called in a professional roofing company to roof it for safety purposes.
A flat roof is the easiest to install and when built correctly is easy to maintain.
Our color preferences limited us in the corrugated department and the fact that we needed pieces that were 12 in length narrowed us down to a polycarbonate roofing product at our local.
The storage building was a slightly different process because the roof also doubled as a deck.
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.
To get the roof started determine how much of a slope you want on your roof.

A roof finished with shingles was a viable option too if it wouldn t have made the treehouse seem too professionally finished and nicer than our barn.
The roof is more than just a lid for your treehouse.
As mentioned above a pitched roof looks better and is easier to waterproof than a flat roof but it takes longer to make.
The down side as you point out is that it is nearly impossible to seal the water from entering through these exit points.
For a standard 8 x8 treehouse choose a tree with a trunk at least 12 in diameter.
You should never use a flat roof for a treehouse.
This durable material is weatherproof in the wind and rain and it insulates the inside from heat in the summer.
A properly sloped or pitched roof is much superior.
I used a 4 12 for the rise and run and this was a good slope to stand on while doing the shingles.
Then the next 2 pix are that of a flat roof for table chairs tree house with a porch overhang.
Divide that number by pi 3 14 to get the diameter.
Step 1 understanding the dimensions even though these are called flat roofs they do have a slight pitch.
To calculate your tree s diameter measure its circumference by wrapping a string or measuring tape around the trunk at the point where you want the treehouse to sit.
