Parts of the Roof

  • Eave – the bottom edge of the roof that hangs off the home
  • Gable – the side edge of the roof that runs from the ridge down to the eave
  • Pitch – the slope of the roof plane, measured by the height of rise over the length of the roof; some roofing systems may be better suited for low- and high-pitched roofs
  • Ridge – the top of the roof where the two slopes meet
  • Valley – the internal area where the bottom of two slopes meet; the valley is generally used for water runoff

    Roofing Materials

  • Shingles – individual components that make up the entire roof; asphalt shingles are the most popular, but metal shingles are also available for improved durability
  • Tiles – a roofing material made of clay or concrete for a Mediterranean or tropical look
  • TPO – a single-ply membrane typically used for flat and low-slope roofs
  • Vertical seams – aluminum and steel sheets that comprise a metal roof

    Roofing Components

  • Coating – an add-on feature that can provide different benefits, such as color-fade resistance and heat reflection for better energy efficiency
  • Fasteners – the nails that are used to hold roofing shingles together
  • Flashing – waterproofing components used around protrusions from the roof, such as a chimney
  • Sealant – a chemical solution used to waterproof joints, cracks, and other areas of the roof
  • Underlayment – a synthetic sheet that is placed below the roof for structural integrity, waterproofing, and insulation
