Slate is a homogeneous metamorphic rock which is formed due to low grade metamorphism. There are many places in Australia which have old homes sporting slate tiles on their roofs. These elegant period homes are closely related to the vernacular style. Slate roofing has been a timeless choice and even now many homeowners want to go for it. Slate roofs need not always look vintage; depending on the product and design, it can give a modern and seamless appearance.
Advantages of slate roofs
Slate has a lot of advantages because it is a natural product made of stone having a unique appearance. Some of the advantages of slate roofs are as follows:
- Slate roofs have a very distinctive look. As slate is composed of 100% stone, they have a naturally cleft appearance and an amazing range of colour variation.
- Slate tiles come in different sizes and thickness. There are numerous styles available ranging from textural and graduated installations to mixed patterns and colours. The texture of the roof can vary from very smooth to very rough. The general colours are in the shades of grey and black but can also be vibrant purple, red or green. The colour of slates is associated mostly with the geographical locations. Westmorland slate is mostly greenish while Welsh slate has a blue hue.
- Slate is completely fireproof which makes slate roofing one of the safest options. It is also mould resistant.
- Slate has a very low water absorption capacity which makes it resistant to freezing and water damage.
- Slate tiles are incredibly durable and can last well over a century with little or no maintenance as compared to other conventional products which have a life expectancy of 30 – 40 years. In some cases, they outlast the longevity of the buildings where they are installed.
- Slate roofing is extremely environment friendly. Due to the composition, slate tiles do not release volatile organic compounds or other pollutants during the manufacturing process. In fact, they can be recycled and reused if they outlast the building. However, residents must be careful not to put paints and sealants on slate roofs as this can cause slate to age prematurely.
- Slate roofing also increases the resale value of the property because it gives a natural beauty to the house and makes it more durable. Good quality slates do not change colour or deteriorate over time.
In spite of all the benefits, there is a downside to slate roofing as well. Slate is heavy and requires trained people to get it placed and the installation may be expensive. Another problem is that many roofers do not know how to install slate roofs correctly. But these issues are minor compared to the advantages.
Slate is a very unique material used for roofing and sometimes people tend to overlook it because they are not familiar with its capabilities. The above mentioned values make slate a very desirable material for roofing.
