Factors that affect the cost of roofing shingles are material, type and style of shingles. The size of the roof also affects the cost of roofing shingles because it determines the number of shingles the homeowner must purchase.
Shingles can be made from several materials, including asphalt, metal, wood and ceramic. Asphalt is the cheapest and costs between $50 and $80, but it offers many advantages, including a wide variety of colors and simple installation. Materials such as slate are generally more expensive and cost between $300 and $600, as of 2015. Types of shingles include organic, fiberglass and architectural shingles. Organic shingles are the most expensive, while fiberglass shingles are the cheapest.
The style of the shingle also affects its price. The three-tab style is popular because it is cheap and easy to install. Dimensional shingles are more expensive, and they offer a unique look and some depth. Interlocking shingles are the most expensive and are quite difficult to install. However, they are advisable for homeowners living in windy areas.
The bigger the home, the more shingles a homeowner needs. Therefore, size significantly determines the cost of the roofing material. Roofing materials are often sold by the square, and one roofing square is equal to 100 square feet.
