In the ideal world homeowners will have a roof that is not too expensive, does not require maintenance and lasts forever. But the reality is that most roofs change every ten years – or at least are repaired. The value of replacement can be decreased by carefully picking the roofing material of your home.
By determining the right tile for your roof in the long run, you will use less money, produce less scrap materials and demand limited natural resources. The reclaimed slate roof tiles are also useful to consider as roofing materials.
The use of slate roof tiles is an international phenomenon and is often found on many impressive buildings, including cathedrals, palaces and mansions. Elite-looking residential homes now use this durable building material to protect it from the forces of nature, while heritage and other prestigious building projects that involve restoration, renovation or expansion are also known for their undeniable quality, permeability. Use slate for colour fastness and aesthetic appeal.
A metamorphic rock
The reclaimed slate roof tiles are metamorphic rocks that exhibit foliage and is fine-grained. If it looks like a little silt, it can help to think of the slate as a special clay that has been heated and sifted. This silt becomes a rock called a shell and changes the chemistry of the heat and pressure shell. Its longevity also makes it suitable for the reclaimed tile market.
Stone slate made of sedimentary rocks (mainly limestone and sandstone) is different from true slate made of metamorphic rock. The main reason for the excellent roof-tiling quality of slate is its cracking.
However, the advantages of slate should also be taken into consideration in any decision, such as its very lifespan, good fire safety, low maintenance and resistance to rot and insects. In many cases the roof will protrude beyond the building covering it. When the roof eventually needs to be replaced, it will be more than likely to be caused by nail corrosion. Roof coverings will be reused frequently.
It is because of this durability that reclaimed slate roof tiles can be considered truly “green” or environmentally friendly. Other roof coverings may need to be replaced several times during the life of a similar slate roof that increases carbon emissions. The material is formed when the rock is pushed into thin sheets by intense pressure.
Divisions and dimensions
The reclaimed slate roof tiles were classified on the foundation of quality and excellence. These are the best, second, third and tone in declining order of nature. Most builders and roofing traders will now classify materials by size and origin. Sizes range from 24 inches by 14 inches to 10 inches by 16 inches at the bottom.
Typically, larger sizes are used to provide increased coverage on larger constructions or under the roof. When building a new roof, the local climate must be taken into account. Due to the way water passes over the roof slate (angle of creep) large size is more suitable for wet climate.
Buying a new roof slate
Premium slate roof tiles cost a lot. The slate is usually considered the most trustworthy on the market. They are inferior to none in terms of appearance and durability. Unfortunately, the cost of three to four pounds each can be restricted. Depending on the size of the structure, you will need between one and two thousand to complete a house.
Add the cost of fittings to this and you may have an expensive roof. However, if you consider the lifetime of the roof over the cheaper options, the price is reasonable. Melbourne and Sydney are of the same quality as the roof slate and a little cheaper. The premium slates offer a great option if budgets need to be cut. At half price they are still quality slate, though they have not yet landed the test of time. The slates are still cheap but many experienced roofers have complained about the brittleness of the product.
Reclaimed slate
Recovered roofing materials provide an environmentally friendly option for covering your roof. Properly used slate will provide an attractive and durable roof if chosen. You should expect to pay around two pounds for a well-recovered slate. It is also advisable to test the reclaimed slates for uniformity and absorbency for appearance.
A simple test can be done by keeping the slate straight in a large bucket. The bucket is then filled with water up to half the length of the slate and left for 12 hours. The water line on the slate will go beyond the water level in the container due to consumption. The higher the water line, the higher the absorption. It should not grow more than a quarter of an inch.
Any slate that fails the absorption test should not be used for the roof as it will not provide weather-tight seals. If the slate starts to fall off, it should also be removed. When cut in half they should be solid without slight layers.
