Asphalt shingles are a popular roofing material because of their look, quality and low maintenance. More than 12.5 billion square feet of asphalt shingles are made annually, which is enough to cover more than 5 million homes, according to iCastle.com. One of the reasons for their popularity is that they can match nearly any type of architecture and are affordable.
You can find two types of asphalt shingles. The first type has a fiberglass center surrounded by hard asphalt, which makes them resistant to fire and also lighter than other types of roofing material. The second type has a cellulose center surrounded by asphalt. This type of shingle is heavier but more flexible. They don’t last as long as some other shingle materials, but they are low maintenance.
Asphalt shingles perform well in all climates — hot, cold, rainy, snowy. Because asphalt shingles are so popular, the high-volume production has reduced the cost of the shingles and they are easy to apply to a roof. Once the shingles are on your roof, they require little or no maintenance. If the shingles are damaged, it is easy to replace just the damaged shingles. You can also purchase shingles that have Class A, B or C fire ratings, with Class A shingles being the most resistant to fire. Some brands of asphalt shingles are also marketed as wind resistant, which means they have demonstrated that capbability in product testing.
For a 1,700 to 2,100 square foot roof, you can expect to pay anywhere from $680 to $3,700 for the shingles, according to Costhelper.com. This would be for standard gray, three-tab shingles, which are the least expensive. As you change colors and choose a better-quality shingle, the price will move up to the high end of the range. If you then have a roofing contractor remove the old shingles and apply the new, the cost will be anywhere from $1 to $4 per square foot or $1,700 to $8,400 in addition to the cost of the shingles. Steep roofs with lots of corners will be at the higher end of the range.
You need to make sure your roof supports can maintain the weight of a shingled roof. Inspect your roof before applying the shingles. You may need to make repairs that could easily add thousands of dollars to you project costs. If disposal of the old shingles is not included in your roofing estimate, it will probably cost you anywhere for $510 to $1,100 to dispose of them.
Shingles are generally sold by the square, or enough to cover 100 square feet. Once you estimate the roof area, add an additional 10 percent for waste for a simple roofline and 15 percent for a steep roof with lots of peaks. Divide the result by 100 to get the number of squares you need. Also, remember to lay a base down on the roof before applying the shingles with nails or tar.
