Common Roofing Inspections


If you have ever wanted a quote on a new roof you will not be surprised that a roofing company will be out to pay you a little visit. They are doing a roof inspection as they walk around your house outside. To someone who is not trained in roof inspections, you have no idea what they are looking for. This article will compile a list so that you will know what these roof inspectors are looking for.

Looking for

Common roof inspections are to examine the following:

  • Broken or missing shingles
  • Mildew, moss or mold
  • Problems with ventilation
  • Ripples, buckles or blistering

Missing or broken shingles

Most residential roofs in the United States are made of asphalt shingles. As these asphalt shingles get old, they can become extremely brittle. A couple of decades of temperature extremes, as well as direct sunlight, will cause this damage to happen. Brittle shingles can break and crack where wind can then tear off pieces of the shingle. While shingles can be completely missing off of the roof.

Moss, mildew, and mold

Moss, mildew, or mold will create ugly patches on the roof. These creations or growths cause damage to the shingles as well as the underlayment or what lays under the shingles. These problems do not occur overnight, so moss, mildew, or mold can also be signs of a roof that has aged past its usefulness.

Problems with ventilation

Most homeowners do not understand that inadequate attic ventilation can be a roof’s biggest nightmare. Ventilation that is poor allows hot air from inside your home to heat the roofing deck, aging shingles by making them extremely brittle and cause curling.

Ripples, blisters or buckles

These three or some of the physical changes that can signal myriad roof problems. These can include:

  • Shingles that are old
  • Ventilation that is inadequate
  • Improper installation
  • Sheathing that is damaged
  • Multiple layers of shingles
  • Underlayment that is wet

And these are all the items that a roofing team is looking for in a roof inspection.
