When installing roofing shingles, one of the most common and economical choices on the market are asphalt roofing shingles. Asphalt roofing shingles are made of organic material or fiberglass and last anywhere from twenty to fifty years. Although they are not the most beautiful roofing materials to use, there are some more decorative asphalt roofing materials today that can also play into the design of the home or office. Asphalt roofing shingles can only be used on pitched roofs, not flat, since they are made to deflect rain and snow rather than deal with small areas of pooling water. A roofing contractor who delt in recladding a house and roof coatings provided the following information.
Asphalt roofing shingles usually cost between sixty to one hundred dollars per square which is very reasonable for pitched roofing material. There are some flat roofing materials that are less expensive than that such as tar and asphalt or roll roofing, but for pitched roofs it is the least expensive on the market. The main consideration as far as installing asphalt roofing shingles is the ventilation so that there is air circulation in the attic space under the roof. There should be one vent per three hundred square feet of roofing material, with half of the vents being near the ridge of the roof and the other half placed near the eaves. If this is done properly, then moss build up should not be a problem and the roof should last its lifetime of twenty to forty years.
The mid-range pricing for roofing material in comparison to asphalt roofing shingles are the metal and rubber roofing materials. Metal roofing material is probably the more popular of the two and has a life of about fifty years, which is excellent. In addition, metal roofing material has more options in color and style, such as imitating tile and slate shingles. Both rubber and metal roofing materials have some sun deflecting properties, depending on the kind used, which helps with energy costs in hotter climates.
The most expensive roofing materials in comparison to asphalt roofing shingles are cedar shakes, tile and slate. Cedar shakes are environmentally friendly, but often have to have fire retardant added to it in order to meet fire codes in neighborhoods which increases the cost. Tile roofing last a long time, but is very heavy to install and can be easily poken during the process which adds to the cost. Slate roofing material is the longest lasting, often lasting over one hundred years. It is also very weather resistant and requires little maintenance after installation. Installation is critical with slate, however, and requires an expert roofing team who is specifically trained in slate roofing.
