Advantages of Thatched Roofs

Durability
Many people think of thatched roofs as shoddy or flimsy. In fact, a skilled craftsman can produce a roof that may last 40 of 50 years. When repairs are made, a new layer is simply placed on top of the old. It is not uncommon to find old buildings in Europe that still have remnants of thatch from Medieval times. When compared with today’s shingles that may last 10 or 15 years, the expense doesn’t seem significant.

Environmentally Friendly
Thatched roofs are considered a green roof. While it is often seen on cabanas, outdoor structures, and landscaping features, it is great for larger buildings as well. Thatch is made of materials that are natural, renewable, and biodegradable. It is one of the greenest roofing materials available for the serious environmentalist.

Disadvantages

The primary disadvantage is the very nature of the material. While thatch is no more likely to catch fire than other materials, it can be more difficult to put out and insurance costs may reflect that. There are also some risks of bird damage. They have been known to nest and forage in newly thatched roofs.

How It’s Made

Thatched roofs are deceptively simple, because it truly takes a master to make a good one. A poorly made thatched roof will be a leaky, drafty mess that falls apart and looks awful. A good one will leave you with a dry and comfortable home that will last for decades

Simple Process
A simple framework supports thatch roofs. A “ridge pole” design made of 2x4s leading from each corner to the center is the primary feature. The four corners are connected by cross beams parallel to the pole. Good reeds should be harvested during the winter and completely dry. The reeds must be gathered into bundles and secured to the frame using wire and pliers. Moving from one bottom corner, across the frame, and then up, the pattern should be repeated until covered. Overlap and tight spacing are very important to prevent leaks and drafts.
