Roofing is an essential aspect of any building, ensuring protection from the elements and enhancing the overall aesthetic appeal. The choice of roofing material is influenced by various factors, with roof pitch being a significant determinant. This guide delves into the intricacies of roof pitch and its influence on the selection of roofing materials.

Understanding Roof Pitch

Roof pitch, often referred to as the slope or slant, describes the angle of the roof. It is represented as a ratio, indicating the relationship between the vertical (height) and horizontal (length) measurements of the roof. Commonly, this ratio is denoted either by a division slash, like 2/12, or a colon, such as 2:12. In roofing terms, the denominator is consistently 12, representing the horizontal measurement. The numerator indicates the vertical height.

For instance, a roof with a 2:4 pitch means that for every four feet horizontally, the roof rises by two feet vertically. Adjusting this for roofing standards, the pitch becomes 6:12.

Determining Your Roof’s Pitch

To ascertain the pitch of your roof, you can use a simple method involving a level. Place one end of the level on the roof, lifting the other end in the direction of the slope. Adjust until the level reading is accurate. Measure a foot from the end touching the roof, then measure vertically from this point to the roof. A four-inch measurement indicates a 4/12 pitch.

Roof Pitch and Its Influence on Roofing Materials

Very Low Roof Pitches: .25/12 to 3/12

Roofs with pitches ranging from .25/12 to 3/12 are typically seen in modern-style homes from the 1960s and industrial buildings. These roofs appear almost flat. Suitable materials for such pitches include:

  • Built-Up Roofing (BUR): Comprising alternating layers of bitumen and reinforcing fabrics.
  • Torch-Down Roofing: A single-layer membrane activated by heat during installation.
  • Rubber Membrane: EPDM roofing, which can be glued or anchored mechanically.
  • Standing Seam Metal: Suitable for pitches as low as .25/12 and also for steeper roofs.

Low to Moderate Roof Pitches: 2.5/12 to 20/12

For pitches between 2.5/12 and 20/12, clay or cement tiles are ideal. However, roofs with pitches between 2.5/12 and 4/12 require double underlayment. Asphalt (composite) shingles are also popular for these pitches, adaptable from 4/12 to 12/12.

High Roof Pitches: 5/12 to 12/12

Wood and slate shingles are perfect for high roof pitches. However, they might not be suitable for the lower end of this range due to potential leaking issues.

Very High Roof Pitches: 18/12

Victorian-era homes often featured sharply angled roofs with pitches as high as 18/12, presenting a steep appearance.
