How Roof Pitch Affects Your Choice of Roofing Materials

Roof PitchFor many homeowners, quality roofing in Daytona Beach, FL, depends largely on the types of materials that go into the installation. However, your choice for the materials you can use for your project may be determined by other factors. Chief among them is the roof pitch.

 

The roof pitch is also known as the slope of the roof. In the construction industry, a roof pitch is defined by a ratio, like 1/12 or 1:12. The first number in this ratio refers to the vertical measurement (height) of the roof, while the second number is the horizontal measurement (length) of the roof. Altogether, the pitch is a ratio that defines how much a roof rises over a set distance.

 

Roof pitch can be separated into two categories. High-pitch roofing is characterized by its steep inclines and sharp angles. The height of the roof changes drastically over the length of the roofing. On the other end of the spectrum is a low-pitched roof, which is characterized as roofing that appears nearly flat.

 

The pitch of your roof has a direct influence over what materials you can use in your project. For instance, some materials may be prone to leaking if they are put on a roof that is not rated for their recommended pitch. Here is a list of common roofing materials and their recommended pitch ranges:

  • Built-up (BUR): .25/12 to 3/12
  • Torch-down Roofing: .25/12 to 3/12
  • Rubber Membrane: .25/12 to 3/12
  • Standing-Seam Metal: 1/12 to 19/12
  • Clay or Cement Tiles: 2.5/12 to 19/12
  • Asphalt (Composite) Shingles: 4/12 to 20/12
  • Wood and Slate Shingles: 5/12 to 12/12

 

Quality roofing begins by working with professional contractors to discuss your project ideas. Before investing in a re-roofing project, speak with a contractor to learn how pitch might affect your options.
