Nine Essential Parts of a Roof

Unless you make a living as a roofer, you probably rarely think about all of the parts of a roof. Most people automatically think of shingles or tiles when considering their roofs, but these materials can’t adequately protect a home without all the other structural elements.

1. Truss

Industry professionals call a roof’s framework the truss. It comprises several components, which include:

  • Rafters: Diagonal beams that rise from the roof’s edges to the ridge and provide support for the decking and roof load
  • Ceiling Joists: Horizontal beams that connect the rafters, frame the ceiling, and support other elements like soffits
  • Collar beams: Horizontal beams connecting pairs of rafters that meet at the roof’s ridge

The truss of a pitched roof also includes struts, purlins, and other elements.

2. Decking

Also called sheathing, roof decking provides the roof’s foundation. It supports all the other parts of a roof that protect the home from water and wind and creates a solid, even surface for nailing down materials.

3. Underlayment

Roofers install a protective felt layer called underlayment over the decking. This waterproof layer adds extra protection to help keep the roof deck dry.

4. Valley Waterproofing

Many roofs feature two or more pitches oriented in different directions. The angled lines where these differing roof pitches meet are called valleys.

Roof valleys present a higher risk of leaks because water and ice tend to accumulate in these areas. To help protect the roof frame and home interior, roofers install special waterproof membranes across these valleys.

5. Flashing

Roofing contractors install sheets of metal flashing (usually steel, aluminum, or copper) to roof sections that need extra protection against intrusive water, such as valleys, chimneys, vent pipes, and roof edges. Depending on its purpose and placement, this flashing may sit above or below other roofing materials.

6. Shingles, Tiles, Shakes, or Panels

Roof shingles, tiles, and other systems protect the interior roof elements. Roofers install these roof cover materials over the underlayment, usually in overlapping rows that encourage rain, snow, and ice to fall down and off the roof. Homeowners have several roofing material options, including:

  • Asphalt
  • Wood
  • Slate
  • Clay
  • Concrete
  • Metal
  • Synthetic materials

7. Vents

A well-sealed roof must include proper ventilation that allows the attic to breathe. An improperly vented attic may trap heat, cold, or humidity, which can cause inefficient heating and cooling of the home’s interior and lead to maintenance issues.

8. Soffits

The roof cover extends beyond a home’s exterior walls, so we must seal the underside of the overhanging roof to prevent intrusion from water, wind, and unwanted pests. Roofers install soffit boards made of wood, fiber cement, or similar materials to seal up these parts of a roof.

9. Fascias

Fascia boards also help seal the roof by providing a drip edge. We install these on the sides of the roof edge, covering the open sections between rafters. High-quality fascia is essential because these boards often help to support rain gutters.
