Slates are one of the most durable materials for modern roofs. A well-installed slate roof can last for a few decades or even centuries. Slate roofing has become highly popular in the world as it comes with multiple advantages. But before settling down to purchase, you should know how to choose them as you want your investment to last as long as possible.
Sizes and categories
Slates are available in different categories. Majority of contractors and builders categorise slates by their origin and size. The size ranges from twenty-four inches by fourteen inches down to ten inches by sixteen inches. Usually, large size slates are used on big buildings or to give better coverage at the roof’s bottom. Moreover, big size slates are appropriate for countries having wetter climatic conditions.
Purchasing new slates
If you are looking to purchase a premium slate product, you have to pay a lump sum amount. Generally, Welsh slates are considered to be the best. In terms of durability and appearance, no other quality can beat them. Each Welsh slate cost around 2 pounds. You will need at least 2000 of Welsh slate to build the roof of your home. By adding fitting cost, installation charges and other costs, you have to spend a hefty amount. However, the price is reasonable in terms of the longevity of the roof. Westmorland and Burlington are a bit cheaper than the Welsh product. Spanish and Chinese are also good alternatives, but many reported about their brittleness.
Testing the slates
If you have purchased the right quality slate, it will not only pass the test of time but also offer you an attractive roof. With the help of a simple test, you can judge the quality of the slates. Keep a piece of slate standing upright in a bucket filled with water halfway to the slate’s length. Leave this for 12 hours. Due to absorption, the water line on the slate will rise higher than the water level in the bucket. The higher the line of water, the greater is the amount of absorption. But it should not go beyond a quarter of an inch. Slates that fail in this test should never be used for roofing purpose. They will fail to protect you from the weather. If you find that the slates are delaminating, discard them immediately. When they are cut in half, they should appear solid.
Composite roofing is made from different plastics and comes with an array of benefits. This offers a robust roofing structure and saves a lot of costs. They look similar to traditional slates, making it hard to tell you the difference. Drop them on the ground or cut them without the fear of breaking. As they are lighter, composite tiles can be used on roofs with weaker slopes or structure. Though it had a few setbacks, new composite tiles are manufactured with an impressive guarantee.
