3-tab Shingles

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.

Pros:

• 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.

Cons:

• 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.
