Have you ever had a neighbor that built a tiki hut in his backyard? You’d probably be jealous. I mean, who wouldn’t want a cool place to hang out in the backyard.

Or perhaps you have plans to live on an island? Well then, you may have considered building a Tiki Hut. But before you do so, you’re probably wondering if they are waterproof enough for your home.

How Are Tiki Huts Waterproof?

Thatched roof like that of those of Tiki huts is traditionally built with grasses or reeds called “cane”. These are interwoven together to produce a homogeneous surface.

Many of the materials used on Thatched roofs contain some amount of silica making it a naturally waterproof material. Not only that it is waterproof but during rainy seasons the stems of the cane become stiffer which in turn giving more protection from seepage.

Also, thatched roofs are typically built with steep angles thus making the rainwater run-off on the sides before it even gets absorbed by the thatch. A pitch of around 50 degrees is desirable to be the most effective.
