Asphalt Shingles are one of the most commonly used types of shingles in the roofing industry. It is one of the most inexpensive options and is relatively simple to install. However, it does require routine maintenance to keep it in good shape and it is not as long lasting as slate and some other materials. In a moist climate, moss and mildew will cover the asphalt shingle and so will need regular removal to prolong the life span of the roof.
One of the main advantages of asphalt shingles aside from the lower cost is that they are available in a huge range of shapes and colors allowing you to obtain a custom look. There are even asphalt shingles made to look like faux slate allowing the appearance of a slate roof at a fraction of the cost.
