Exterior Inspection

Exterior Inspection

When it comes to home inspections, the exterior of a property plays a crucial role in identifying potential issues that can affect its structural integrity and overall condition. Unfortunately, certain aspects of the exterior are often overlooked, leaving homeowners vulnerable to hidden problems.

Let’s dive into the three key areas of exterior inspection that are commonly missed: the roof, foundation, and gutters/drains.


The roof is your home’s first line of defense against the elements, making it essential to thoroughly examine its condition during an inspection. However, many people fail to recognize some common roof issues that can have significant consequences if left unaddressed.

One frequently overlooked problem is roof leaks. Water intrusion can cause extensive damage, leading to mold growth, compromised structural integrity, and costly repairs. During a visual inspection, it is crucial to look for signs of water stains on the ceiling or walls, damp insulation, or discolored patches on the roof.

Additionally, missing shingles or tiles can go unnoticed, especially when they are not easily visible from the ground. These gaps allow water to seep into the underlying layers, accelerating wear and tear. Inspectors should pay close attention to any areas where shingles appear loose, damaged, or absent.


The foundation is the backbone of any structure, providing stability and support. Yet, potential foundation problems are often missed during inspections, leaving homeowners vulnerable to issues that can worsen over time.

Cracks in the foundation are a common red flag that should not be overlooked. Even hairline cracks can indicate underlying issues, such as settling or shifting of the soil, hydrostatic pressure, or structural defects. Inspectors should carefully examine both the interior and exterior foundation walls for any signs of cracks, no matter how small.

Unevenness or sloping floors can also be indicative of foundation problems. If the floors feel uneven or if doors and windows don’t close properly, it may be a sign of foundation settling or shifting. These issues can lead to structural instability and require costly repairs if not addressed promptly.

Water damage around the foundation is another commonly missed problem. Poor drainage can cause water to accumulate near the base of the house, leading to erosion, moisture infiltration, and potential foundation damage. Inspectors should evaluate the grading around the property, ensuring that water is directed away from the foundation and that gutters and downspouts are functioning correctly and a proper drainage system is in place.

Gutters and Drainage

While gutters and drainage systems may seem like minor components of a home’s exterior, their importance should not be underestimated. Faulty gutters and inadequate drainage can lead to a multitude of major problems, including water damage, erosion, and even foundation issues.

During an inspection, it is crucial to assess the condition of gutters and downspouts. Look for signs of clogging, rust, or damage that can impede proper water flow. Inadequate gutters can result in water overflowing onto the roof or pooling near the foundation, causing significant damage over time.

In addition to gutters, inspecting the overall drainage system is vital. Check for proper grading around the property to ensure water is directed away from the house. Standing water near the foundation can seep into the basement or crawl space, leading to dampness, mold, and other water-related issues.

Understanding the impact of improper drainage on the property is crucial. It not only affects the structural integrity but also increases the risk of water infiltration, which can result in expensive repairs and potential health hazards.

Interior Inspection
