Asphalt shingles are the most common form of roofing material used in the United States, primarily because they are so affordable. With a wide variety of colors and styles, asphalt shingle roofs are an economical and attractive way to spruce up your residence. One criticism of shingles used to be that the boring or repetitive look caused every roof on the block to look the same. Those days are over thanks to the advent of dimensional shingles.
Dimensional shingles, also known as architectural or laminated shingles, are asphalt shingles with a twist. Regular asphalt shingles have three regularly spaced asphalt tabs, giving the roofing material a very repetitive pattern. Dimensional shingles have two layers of shingle material bonded together. However, random notches have been taken out of the shingle, exposing the bottom layer. This gives these new shingles a three dimensional look, with different high and low tabs.
Because of the double bonded layer, dimensional shingles actually offer more protection from wind and hail — with the heaviest grades able to withstand 120 mph winds. They also have a longer lifespan — 40 years compared to the average 20 years for the single layer asphalt shingles.

Advantages to asphalt shingles:
Some roofing materials require regular maintenance (like shake shingles), whereas asphalt shingles require almost no maintenance. While they aren’t as tough as tile shingles, they do hold up fairly well to the challenges of Mother Nature. If they are damaged, asphalt shingles are easily repaired and cheap to replace by qualified roof replacement and maintenance experts.
