Metamorphic rock is forged by great heat and pressure deep within the earth's crust. While slate may have started life as unextrordinary shale, thanks to a good baking in the earth, slate has some pretty fantastic features. If you are looking for a good-looking, impervious roof, slate is a good choice.
Go Green with Slate
If you have a strong environmental conscience, then you will want to choose green, or earth friendly, roofing materials for your home. Slate is just such a material. It is harvested from quarries, and while this does disturb the earth, quarry workers use very few machines in order to extract the slate and split it into shingles. As compared to materials such as metal roofing or asphalt shingles, quarrying requires much less processing. Thus, it uses less of earth's resources and requires far less infrastructure to produce.
Reduce the Need to Replace Your Roof
Another consideration when going green is how long your roof lasts. For example, the ubiquitous asphalt shingle will last only 20 years. That might seem like a long time, but consider that soft slate can last for 125 years and hard slate can last for 200 years. In other words, when you install a slate roof on your home, you will likely not have to worry about replacing it during your lifetime. Not only will this help you save money, but it will reduce the need to harvest and manufacture new materials to replace your roof, which reduces the strain on earth's resources.
Exposed to the full assault of mother nature's arsenal, roofs can degrade faster than any other part of your house. Thus, you want to make sure that your roof is up to the abuse. Slate will not dent or break when hail falls, nor can gale-force winds strip it off of your house. The same UV rays that can dry out asphalt shingles, making them brittle and prone to cracking, will have no effect on slate. On the other hand, falling limbs or even poorly placed steps as you walk across your slate shingles can crack them. However, as long as you don't have overhanging limbs or the need to walk on your roof, you should get good durability from your slate roof.
Slate costs more than the more common asphalt shingle, but you get a lot of quality for your money. Thus, if you are looking for a low-maintenance, earth friendly, and/or good-looking roof, then slate shingles are worth considering. Talk to a company like Skywalker Roofing for more information.
