The Anatomy of a Roof: Understanding Each Part

Learning the different components of a roofing system gives homeowners better, more accurate ideas whenever issues come up. More than that, knowing how each part benefits the home gives them a better understanding of how to better care for the roof.

The Anatomy of a Roof: Understanding Each Part

Here are the most basic components of a roofing system you should be aware of.


Just as the roof is your home’s primary protection against the elements, the shingles are your roof’s first line of defense. The most common types of shingles available today are wood, shakes, metal, tile and asphalt shingles. Asphalt shingles, either three-tab or architectural, are the most popular.

Roof Deck

You can think of this part of the roof as the foundation because everything rests on it. The material used for decking varies, but the most common ones are either plywood or OSB (Oriented Strand Board). However, homeowners have other options, such as polystyrene, concrete and metal.


The underlayment provides an extra layer of protection, mostly against water intrusion, if water penetrates the shingles. As a temporary barrier against the elements, this felt material keeps moisture out until you can contact a proper contractor for roof repair services.

While the roof consists of other components, these are the basic parts you should know about. By taking the time to learn about them, you can get a better understanding of how to keep your roof in top shape.
