Understanding the Main Parts of a Roof

Homeowners should take the time to learn about the different parts of the roof as well as their functions. This can help them easily determine what specific problems they may encounter before contacting roofers in their region.

Understanding the Main Parts of a Roof

Today, DryTech Roofing shares a brief description of the main components of a roof:

  • Decking or Sheathing

This is used to close and reinforce the roof’s structure as well as provide a stable nail bed for shingles.

  • Shingles

These are components that help protect the roof from rain while also improving the house’s overall aesthetic. Most roof repair service providers usually handle issues with shingles.

  • Underlay Membrane

This is a layer used to protect the roof shingles against resin as well as protect the decking against extreme weather conditions.

  • Roof or Eaves Edge

These are boards that run along the edge of the roof.

  • Attic

This is the area or space that’s usually under the roof. This space requires proper ventilation to protect the roofing system from excess heat in the summer as well as air generated by the house’s heating systems during winter.

  • Roof Vents

These are enclosed openings and fins that help ensure the attic is properly ventilated. These usually have four open sides and are a few feet above the roof. They work by capturing the wind, which helps produce a sucking effect.

  • Deflector

These as rafters that help secure proper airflow over the insulation near the soffits.

  • Saddle

This is the structure found behind the higher side of the chimney. This works by diverting rainwater around it to prevent leakage.

  • Valley

This is another name roofers use to refer to the V-cut angle found along the junction of the folds.

  • Drip Edge

A special molding that helps cover the roof edges, reducing the chances of water infiltrating into the home.

  • Plumbing Vent

Plumbing vents are pipes that emerge from the roof that introduces air into the plumbing system to allow wastewater to flow effectively to the sewer systems.
