What Is a Thatched Roof?

The thatched roof is a roof that is made from plant material such as straw, oats, rice, wheat, rye, or bamboo.

While ancient roofing forts and homes were made from thatch, most modern homes use slate, rubber, tile, aluminum, or metal as their roofing, but most traditional homes still use thatch.

Historically, a thatched roof is made from dried leaves and reeds. The roof is a type of roof that would be a common type of roof in a tropical region.

A thatched roof has a lot of advantages like the roof cools the home more than a traditional roof, but also traps more hot air.

A thatched roof will also help with protection against heavy storms. The roof material is however not fire resistant.

Thatch Roof History

Thatch roofing originated in the mid-18th century where straw or reeds were used as a roofing material instead of wood shingles.

Thatch roofs were used because they required little construction to build and roofs could be built quickly. Straw was mixed with lime, clay or cow dung juice to make a dense foam that would hold heat well.

This mixture would be applied onto the roof in thick layers before being smoothed out with furled cloth strips. Thatch roofs were an effective way of making buildings but they were very difficult to repair.

Thatch roofs dried quickly so if a leak occurred it would be difficult to fix as the material would not be moist enough to repair, like wooden shingles.

Thatch roofs were cheap to build but they did not last long without maintenance. The main issue was that it was extremely difficult to patch or repair the roof once it had started to deteriorate.

The straw that was used to build thatch roofs were also prone to fire and would burn easily.

The colours of a thatch roof can range from dark green or black through to grey. This is based on the type of material and the position of the sun in the sky.

The green appearance comes from algae and moss growing on top of roof material which has been moist for a long period of time.

The colours of a thatch is also affected by human activity such as soil and rainfall. The colour of the thatch roof may also be affected by the type of wood used to make the shingles because of their different colours.

A thatch roof can be more effective in keeping out the rain and protecting a building but they are not perfect, some changes have been made to them to help them perform better.

With modern materials such as zinc, and more advanced technology it is possible get a thatch roof with more insulation.

People in some areas of the world use thatch roofs to protect their buildings as well as making them look attractive. These buildings are constructed in a similar way to a thatch roof but are made from other materials.

They are almost always built over a mound or platform which may be made from earth, wood or metal. There may also be a sloping roof built above the thatch slabs. The thatched roofs provide shelter, warmth and protection for people nearby.

Thatch roofs are used in many areas of the world today as they have low maintenance, good insulation and can be made quickly.

However, there are some disadvantages to them such as increased fire risk and they are not very good at keeping out water.

Thatch Roof Maintenance

To maintain a thatched roof, regular inspection is necessary as the materials may deteriorate easily.

The pitch of the roof should be kept low so that water doesn’t pool on it.

The design of the thatched roof should be made with a good drainage system. The slanting-pitched roofs help to ensure there are no standing pools of water which in turn reduces the risk of decay from mould and other weathering factors.

To inspect the roof for wear and tear, it is necessary to ensure the thatches are healthy. It is best to needs a professional roofing contractor to do these checks as they have the necessary tools for doing this job.

To ensure there is proper drainage, it is necessary to clean the guttering and rainwater outlets every year.

New roofs should be constructed first before the old roofs are repaired. It is not advisable to repair a thatch roof when it already has some damage.

This is because repairs will only prolong the roof life. The best way to fix a thatch roof when it has damage is to completely replace it with a new one.

It may be possible today but most materials used in constructing of a thatched roof are not fire resistant.

Problems With Thatched Roofs

The first issue with thatched roofs is the expense. It is difficult to make a thatched roof and it can be expensive to make one that will last.

The second issue with thatched roofs is safety. Thatched roofs are made of straw. If it gets too close to an open fire, the fire can quickly spread onto the roof.

Some of the thatched roofs are more prone to imperfections than others. It can be difficult to repair, especially if they have been damaged.

Decaying thatch is dry and rough on the roof and can cause problems when it comes to fixing leaks. More of a challenge is removing the decaying thatch to ensure a good waterproofing layer for roof repairs.

Another issue with these roofs is that they are vulnerable to wind damage. The materials are typically susceptible to strong winds because of their flexibility.

To prevent this, many houses now have steel or aluminum strips that are layered over the roof. The strips create an added layer of stability that prevents the roof from swaying during storms.

Finally, thatched roofs pose a fire risk and are not very good at keeping out water. The plastic panels commonly used today in constructing of a thatch roof are fire resistant but they may crack or move over time.

The construction materials for thatching are becoming more inaccessible and expensive. The main building materials for this type of roofing are straw, hair, reeds, and grasses such as clover and bracken.

3. Prone to fire

Thatch roofs are easily prone to fire because of the materials they are made from. When burning, it will create sparks that could lead to a large fire.
