The roof over your head

Roofs are important, no matter how big or small your home is. Without them, you’d be at the mercy and whim of any weather. Nobody wants to watch their favourite television show while having to dodge raindrops falling from above. Here are some interesting roofing facts:

The oldest roofing materials

Some of the materials that we use for roofing have been around for many years. Stone, clay, and thatch are the oldest roofing materials. Thatch, for example, was thought to have been used around 5,000 BC. It was a popular option in roofing until about 1,800 BC. Clay tiles are even older, with examples dating back to 10,000 BC.

Thatched roofs were popular due to their natural waterproofness. The reed is bundled and tied together tightly. The roof will shed any water that falls on it. A thatched roof is able to withstand the impact of rain, snow and even sleet. For help from Roofers Bristol, contact https://www.mogfordprescott.co.uk/roofers-bristol

Spotting and fixing roof leaks

Leaks are most often caused by damage to your roof’s tiles, slates or waterproofing layer. The leaking might mean you will need a brand new roof. However, the earlier you address any issues that may arise the less likely it is that permanent damage will occur. Don’t forget that water can travel before it drips down, so you may not find the leaky tile in the same place as the water.

The rise of green roofs

Green roofs are popular among many people, particularly those who care about the environment. They are basically roofs with plants growing on them. You should maintain them, particularly the area that is a water barrier. The soil and plants that you install protect your roof from sun and water damage, as well as extremes of temperature and fluctuations.

From mud and straw to clay tiles

People have been building shelter for thousands of years, and roofs have changed a great deal along the way. Some of the earliest homes were made from mud and straw, and their roofs used the same materials. Each year a fresh layer of mud and straw was added to keep the roof as watertight as possible.

Thatch developed from these early roofs. Bundles of reeds are tied together and laid in layers, then covered with netting to stop birds and animals getting into them. Reeds resist water naturally, which is why they work so well, although a thatched roof still needs replacing over time to stay effective.

Clay tiles were first used in China, and many other tiling materials have been developed since. They have stayed popular for the same reasons: they are durable, and their shape lets rainwater run off the roof quickly rather than soaking in.

How long common roofing materials last

A roof’s main job is to channel rain and melting snow into the gutters and drains so that nothing leaks through to the loft and ceilings below. The material you have affects how well it does that and how long it will last.

Thatch, made from tightly bound and cut straw, keeps out the wet remarkably well but needs replacing regularly. Dark Welsh slate became the standard from the seventeenth century onwards. It is easy to cut and shape, takes a nail, sheds rain very well and should last around a hundred years.

Clay tiles have a similar lifespan of about a century. They absorb heat so it does not pass into the house, which is why they are so common in Southern Europe and Latin America. Metal roofs were once avoided because of rust, but paint and nickel coatings have changed that, and with care they can last up to seventy years.

Summary

Covers some interesting roofing facts, from the age of materials like thatch and clay tiles, which date back thousands of years, to how thatched roofs shed water naturally, why leaks often trace back to damaged tiles, slates or waterproofing and can travel before showing up, and the growing popularity of green roofs planted with vegetation.
