A Quick Guide to the Different Parts of Your Roof

by | Jun 11, 2019 | Roof Tips | 0 comments

At Elite Roofing and Restoration Services, we understand that not everyone is as familiar with the parts of a roof as we are. Sometimes the industry terms can be confusing when you’re not exposed to them every day. We always want our customers to know what we’re talking about when we discuss their roofing project with them, so we’ve made this quick guide to the different parts of a roof. It never hurts to learn more about such an important part of your home or office!


Roof Anatomy 101

A roof is made up of sturdy layers that are designed to keep coolness and warmth in and keep rain and moisture out. Water damage is the bane of your roof’s existence, so nearly every part of the roof, from the shingles to the eaves and underlayment, has been designed with the goal of keeping water from pooling and causing damage.

Other structures, like the decking and rafters, are built to support the substantial weight of the roof. Without them, your roof would be in danger of caving in and collapsing.


Here are the most common parts of the roof that you should be familiar with:

  • Decking. Decking is a plywood base that covers the rafters. All other roofing materials are attached to the decking.
  • Dormer. The dormer is a window structure on the roof slope. They are commonly used to increase space and let light into a loft or attic room.
  • Drip Edge. This is an edge that is added to steer dripping water away from lower sections of the roof.
  • Eaves. The part of the roof that overhangs the wall.
  • Fascia Board. The long, straight board that runs along the lower edge of the roof.
  • Fascia Trim. Trim that covers the rafter end of the eaves.
  • Flashing. Pieces of metal installed to prevent water seepage around any intersection or projection of the roof, like pipes, vents, and valleys.
  • Gable. A gable is the triangular wall created by the intersection of two sides of a sloping roof.
  • Hip. On a hip roof, all sides of the roof slope down toward the walls.
  • Hip and Ridge Shingles. Accessory shingles used to finish the hips and ridges of the roof.
  • Rafters. Structural support members that slope down from the ridge to the eaves.
  • Ridge. The highest point of the roof that runs along the length of the roof.
  • Ridge Vent. Added to provide ventilation through the ridge.
  • Roof Truss. The framework of beams that, with the rafters, acts as the roof’s skeleton.
  • Shingles. Attached to the underlayment to create the surface of the roof. Shingles come in asphalt strip shingles, heavier dimensional shingles, and laminated premium shingles.
  • Soffit. The finished underside of the roof’s overhang.
  • Underlayment. Felt or fiberglass installed under a roof deck before the shingles are installed. Underlayment provides a water-resistant layer.
  • Valley. The valley is a V-shaped metal channel that runs up and down the folds of a roof.
