  1. Asphalt Shingles: Asphalt shingles are the most common type of roofing material used in residential construction. They are made from a fiberglass or organic mat coated with asphalt and granules. Asphalt shingles come in a variety of styles and colors and are known for their durability and affordability.
  2. Underlayment: Underlayment is a layer of material installed between the roof deck and the roofing material (such as shingles). It serves as a secondary barrier against water intrusion and helps protect the roof deck from moisture damage.
  3. Flashing: Flashing is a thin, weather-resistant material installed around roof penetrations, such as chimneys, vents, and skylights, to prevent water from seeping into the roof system. Common types of flashing include metal, rubber, and plastic.
  4. Ridge Vent: A ridge vent is a ventilation system installed along the peak of the roof to allow hot air and moisture to escape from the attic. Ridge vents work in conjunction with soffit vents to promote airflow and regulate temperature and humidity levels in the attic space.
  5. Ice Dam: An ice dam forms when snow melts on the roof and refreezes at the eaves, creating a barrier that prevents water from draining properly. Ice dams can lead to water backup and leakage into the home, causing damage to ceilings, walls, and insulation.
  6. Fascia: Fascia is the vertical band of material that runs along the edge of the roof and covers the ends of the roof rafters. It provides a finished look to the roof’s edge and helps support the gutter system.
  7. Eaves: The eaves are the lower edges of the roof that overhang the exterior walls of the house. Eaves protect the walls from water runoff and provide shade and shelter for windows and doors.
  8. Pitch: Pitch refers to the slope or angle of the roof, typically expressed as a ratio of rise over run. A roof with a high pitch has a steep slope, while a roof with a low pitch has a shallow slope.

FAQ: Common Roofing Terms Every Homeowner Should Know

What is a “shingle”?

A shingle is a flat, rectangular piece of roofing material that overlaps in successive layers to cover the roof. Shingles can be made from various materials, including asphalt, wood, slate, and metal.

What does “flashing” refer to in roofing?

Flashing is a thin material, typically made of metal, used to direct water away from critical areas of the roof, such as joints, seams, and valleys. It helps prevent water penetration and leaks.

What is a “roof valley”?

A roof valley is the internal angle formed by the intersection of two sloping roof planes. Valleys are designed to channel water off the roof and into the gutters, and they require special treatment to prevent leaks.

What is a “ridge” on a roof?

The ridge is the highest point on a roof where two sloping sides meet. It often has a ridge vent or ridge cap to allow ventilation and protect against weather elements.

What is an “eave”?

The eave is the lower edge of the roof that overhangs the walls of the house. Eaves help direct water away from the walls and foundation and can include features like soffits and fascias.

What does “underlayment” mean in roofing?

Underlayment is a protective layer installed between the roof deck and the shingles. It acts as a secondary barrier against water infiltration and is typically made of felt or synthetic materials.

What is a “roof deck”?

The roof deck is the structural surface to which the roofing materials are applied. It is usually made of plywood or oriented strand board (OSB) and provides the foundation for the roofing system.

What is “roof pitch”?

Roof pitch refers to the steepness or slope of the roof. It is usually expressed as a ratio of vertical rise to horizontal run (e.g., 4:12, which means the roof rises 4 inches for every 12 inches of horizontal distance).

What is a “gutter” and why is it important?

Gutters are channels installed along the edges of the roof to collect and direct rainwater away from the house. Properly functioning gutters prevent water damage to the roof, walls, and foundation.

What are “soffits” and “fascias”?

Soffits are the undersides of the eaves, providing ventilation to the attic. Fascias are the vertical finishing edges that cover the ends of the rafters and support the lower edge of the roof tiles or shingles.

What is a “drip edge”?

A drip edge is a metal flashing installed along the edges of the roof to direct water away from the fascia and into the gutters. It helps protect the roof’s underlying components from water damage.

What is the purpose of a “vent pipe”?

A vent pipe, often seen protruding from the roof, allows gases and odors from the plumbing system to escape safely. It helps maintain proper air pressure in the plumbing system and prevents water traps from being emptied.

What does “R-value” mean in roofing?

R-value measures the thermal resistance of roofing materials, indicating their insulating effectiveness. Higher R-values mean better insulation properties, which can improve energy efficiency.

What is a “hip roof”?

A hip roof has slopes on all four sides that come together at the top to form a ridge. This design provides additional stability and resistance to wind damage compared to other roof types.

What is “ventilation” in the context of roofing?

Ventilation refers to the system of vents (such as ridge vents, soffit vents, and gable vents) that allow air to circulate through the attic. Proper ventilation helps regulate temperature and moisture levels, protecting the roof and improving energy efficiency.
