Understanding the Anatomy of a Roof & Its Many Layers


Some falsely assume that a roof is little more than a layer of shingles, tile, metal, or other outer material. But that’s only part you can see from the outside; there’s actually quite a bit more to a complete roof system! Thankfully, we make everything clear in this helpful infographic!

Here are just a few of the roofing layers that we dissect, all of which play a role in helping to protect your home from heat, humidity, sun, wind, and precipitation:

  •       Ventilation – Essential for allowing proper air circulation around the roof. Without adequate ventilation, heat and moisture can damage the framing, insulation and underlayment, and can shorten the outer roof layer’s lifespan.
  •       Ice & Water Shield – This is a self-adhered waterproofing material installed along eaves, valleys, side walls, and other sensitive areas to protect against ice damage, wind-driven rain, and moisture.
  •       Shingle Starter Strips – Either specially designed, or created by breaking shingles in half. They’re installed at the eaves to create a first line of defense against wind uplift along the roof’s edge.
  •       Roofing Material – This outermost weatherproof layer comes in many material, style and color options. The most common home roof categories include asphalt shingles, wood shakes, tiles, slate, composite materials, and metal.
  •       Flashing – Sheet metal is used to prevent water from penetrating seams where different materials meet. It’s also used around chimneys, skylights, bathroom vents, and any other protruding roof features.
