A roof over your head isn’t just a blessing—it’s multiple blessings. That’s because this standard part of your home or business is composed of various smaller parts. Understanding these components can help you assess your roof better, and make you more comfortable reaching out to your local roofing contractor for help with any of these parts.

5 Common Parts of a Roof

1. Decking

This component serves as the base of the roof and is usually made of wood. In some rare cases, polystyrene, metal, and even concrete can be used. Decking is usually attached to the rafters, providing a solid foundation for the roof’s shingles.

2. Underlayment 

Between the decking and the shingles is the underlayment. As the name suggests, it lays under the shingles for the primary purpose of moisture control. Usually made of felt or synthetic, it can resist water and stop both the decking and the shingles from rotting because of it.

3. Shingles

What may seem like the only part of a roof is simply its outer shell. With a strong foundation set up for stability and ventilation, a roof can provide years of reliable use in most cases, no matter what shingles are used. Standard options include asphalt, metal, clay, and even wood. If you’re unsure which option would be best for you, consult with your local roofing contractor. 

4. Ridge Vent

This feature is especially common in buildings that have attics, which can tend to get warm thanks to heat’s tendency to travel upward. By allowing the warm and humid air a means of escape, it stops it from pressing up against the decking, underlayment, and shingles, so there’s less of a chance it harms them.

5. Flashing

Flashing can be thought of like small sections of sheet metal. It’s installed anywhere there could be an opening to keep drafts, pollen, insects, moisture, and other debris out. Flashing is commonly used around the vent, chimney, and points where sections of roof material meet.
