Shingle roofs come in come in two basic varieties; three-tab shingles and architectural shingles. Many manufacturers also make designer shingles that are made to look like other materials, like wood shakes or slate. These shingles are generally more durable and have a distinctive look, but are also considerably more expensive.
As the table above indicates, three-tab shingles have an average lifespan of 25 years under ideal conditions. Architectural shingles generally last for 30-years, and longer lasting versions are available. If you are in an area that is prone to high winds, then architectural shingles may be a great option, as they are guaranteed to stand up to stronger wind speeds than three-tab shingles. While a roof of any age can be damaged by hail of sufficient size, architectural shingles are also more resistant to hail damage. Although opinions differ from person to person, most people seem to like the appearance of architectural shingles more as well, as they create a more "high end" look. If you are looking to replace your shingle roof, then architectural shingles clearly deserve a great deal of consideration.
