One of the most common type of shingle are 3-tab shingles. 3-tab shingles get their name from the amount of tabs on each shingle. 3-tab shingles are identified by their pattern (three notches, hence the name 3-tab) at the lower edge of the shingles. They are designed in a single, flat layer, with the three tabs placed evenly apart on the lower end. These tabs fit together like a puzzle when the shingles are installed. The result is a very uniform, flattened pattern of rectangular shingles. 3-tab shingles are very easy to install since they are composed of a thin, lightweight material.
3-tab shingles have been around for a long time, and most roofers are very familiar with them.
Their very simple design makes them easy to install and easy to repair. Because the shingle pattern is always the same, you know exactly what you are getting.
These thin shingles are also some of the most affordable shingles on the market, so they are a good choice if you need to save money.
3-tab shingles do not meet Lafayette, Louisiana’s building code wind speed requirement. Any shingle installed on a roof in Lafayette, La is required to have a warrantied wind speed of 110 mph.
3-tab shingles are only warrantied at 60 mph winds.
A 3-tabs life span is the lowest of all asphalt shingles.
3-tab shingles do not have higher end algae protection that is found in modern day architectural shingles.
They are more susceptible to wind and hail damage than other types of shingles.
The install time of a 3-tab shingle roof is longer due to their smaller size compared to other asphalt shingles.
