About Slate Roofing
If you are looking for elegant and sturdy roofing, then slate is what you should go for. One of the most durable roofing materials available, it can provide solidity and class to your house roof.
Slate is a type of homogeneous metamorphic rock, derived from the metamorphosis of sedimentary rocks. It occurs predominantly in gray color, though other shades, ranging from purple, green, to cyan are also available.
This roofing type is popular in Europe and 90% of its supply, originates from Spain. It is mined worldwide, as it is a versatile material used in roofing, as well as flooring. In USA, these roofs are still opted for by many, but metal, asphalt, and other new types are more popular.
Slate can be easily converted into roofing shingles due to the two lines of breakability it has, which are grain and cleavage. Due to this property, it can be easily split into thin sheets. What makes it an ideal candidate for roofing shingles is its water absorption index, that is lower than 0.4%.
This low water absorption rate, makes it impervious to breakage, caused by freezing and frost damage. The only minus point of slate as a roofing material, is its weight. Due to the heaviness of this type of roofing, extra reinforcement may be needed, during installation. No roofing is perfect and it comes with its share of shortcomings and advantages.
They come in two types. One is natural mined slate and the other is a synthetic variety, made from rubber and plastic composites. The synthetic types are made to look like natural slate but are much lighter.
The cost of a slate roof depends on many factors, including the type of slate, roof design, height, its square footage, and the method of installation. If you opt for natural slate, the overall cost per square foot ranges from USD 9 to USD 40, depending on the quality of slate.
Instead, if you opt for synthetic slate, the cost per square foot will be USD 7 to USD 9 only. The overall costs will include the charges for reinforcement, that may be required in case you opt for natural slate, and also the cost involved in removing previous roofing material, if any. Compared to asphalt roofing, this one is costly but it provides a host of advantages, including moisture and fire resistance.
Buy high quality slate to ensure a longer life for your roof. Talk with local contractors about the local costs as they vary highly, with location. Natural slate roof installation is a masonry job, that requires a high degree of skill and accuracy. Go for an experienced contractor, who can ensure that the project is finished in a reasonable amount of time.
