What Roofers Look For When They Inpect a Roof

Updated: Mar 13, 2023


Many times determining if your roof is still in good health, needs repair, or needs an entire replacement comes down to a reputable and credible inspection. There are some basic components to a roof inspection that every roofer should be looking at and evaluating. Read on to see what you can expect from a qualified roof inspection.


At Herring Residential, we share all the parts of a roof inspection that we work through when we are hired to inspect your roof whether it is a residential or commercial building.


There are two parts of a roof inspection that involve assessing the health of the interior and exterior of the roof. There are physical signs that signal issues and will warrant recommended repairs or replacement.


  • Roofing materials are either missing or in poor condition.

  • Growth of moss or algae

  • Pooling or sitting water

  • Broken and rusty parts




During a roofing inspection, roofers examine the interior of the roof to identify any problems that may be affecting the structure. This process helps them to determine the cause of any leaks, cracks, or other issues and recommend the best course of action to resolve the problem. In this blog, we will discuss what roofers look for on the interior of a roofing inspection.



  • Signs of Moisture Damage: Roofers will inspect the interior of the roof for signs of moisture damage, including water stains or mold growth. These are indications of water infiltration, which can lead to a host of issues, including rotting wood, structural damage, and health hazards from mold growth. Moisture damage can be caused by a variety of factors, including roof leaks, poor ventilation, and humidity levels.

  • Proper Ventilation: Roofers will also examine the ventilation system in the attic space. Proper ventilation is essential for preventing moisture buildup, which can cause damage to the roof deck and insulation. Without proper ventilation, condensation can form on the underside of the roof deck, leading to mold growth, rot, and other issues. Roofers will check for adequate ventilation, including intake vents at the eaves and exhaust vents at the roof's peak.

  • Structural Integrity: Roofers will inspect the interior of the roof for signs of structural damage, including cracks, sagging, or bowing. These issues can be indicative of a more significant problem with the roof's structural integrity, which can compromise the safety and stability of the roof. Structural damage can be caused by a variety of factors, including poor installation, excessive weight, and weather-related stress.

  • Insulation: Roofers will examine the insulation in the attic space. Proper insulation is essential for maintaining a comfortable temperature inside the home and preventing heat loss or gain. Insulation can also help to prevent moisture buildup and reduce energy costs. Roofers will check for adequate insulation levels and any signs of damage, such as compression or wet insulation.


During the exterior portion of the roofing inspection, experts examine the outside to identify any problems that may be affecting the structure. Much like the interior portion, they are looking for areas that may be the cause of any leaks, cracks, or other issues and recommend the best course of action to resolve the problem.


  • Shingles and Roofing Material: Roofers will inspect the shingles or roofing material on the exterior of the roof. They will look for any signs of wear and tear, such as cracks, curling, or missing shingles. They will also look for any signs of damage caused by weather, such as hail or wind damage. Roofers will also check for any signs of deterioration caused by age or exposure to the elements.

  • Flashing: Roofers will inspect the flashing on the exterior of the roof. Flashing is a thin piece of metal that is used to seal gaps and prevent water from seeping into the roof. Roofers will look for any signs of damage or deterioration, such as rust or missing flashing. They will also check to make sure that the flashing is properly installed and sealed.

  • Gutters and Downspouts: Roofers will also inspect the gutters and downspouts on the exterior of the roof. Gutters are designed to channel water away from the roof and the foundation of the house. Roofers will look for any signs of damage, such as cracks or holes, that could cause water to leak onto the roof or the foundation. They will also check to make sure that the gutters are properly attached and sloped to ensure proper drainage.

  • Chimneys: Roofers will inspect any chimneys on the roof for signs of damage or deterioration. They will check for any cracks or gaps in the mortar, which could cause water to seep into the chimney and the roof. They will also check to make sure that the chimney is properly sealed and that the flashing around the base of the chimney is intact.

  • Ventilation: Roofers will inspect the ventilation system on the exterior of the roof. Proper ventilation is essential for preventing moisture buildup and maintaining a comfortable temperature inside the house. Roofers will look for any signs of clogs or damage to the ventilation system, including the ridge vents and soffit vents.
