When it comes to buying a property, inspections are a crucial step in ensuring you’re making a sound investment. While most buyers prefer to view homes on a bright, sunny day, there’s actually a huge advantage to inspecting a property when it’s raining. Wet weather can reveal hidden issues that might otherwise go unnoticed, potentially saving you thousands in unexpected repairs down the track.

Here’s why a rainy-day inspection is one of the best ways to truly assess a home before you buy.

 

1. Spot Drainage and Flooding Issues

A key concern for any homeowner is how well a property handles water. Heavy rain will instantly highlight poor drainage around the home, revealing:

 

• • Water pooling in the yard – A sign of poor grading or blocked stormwater drains
  • Flood-prone areas – Especially important in low-lying areas or properties near creeks and waterways
  • Runoff issues – Water flowing toward the house instead of away, which could lead to future structural problems

If water isn’t draining properly, you may be looking at expensive landscaping or drainage fixes post-purchase.

 

2. Check for Roof Leaks and Gutter Problems

A home’s roof and gutters are essential for protecting it from the elements. On a dry day, it’s impossible to tell if a roof is leaking, but during wet weather, you’ll quickly see signs such as:

 

• • Water stains on ceilings or walls
  • Dripping or active leaks inside the house
  • Overflowing gutters and downpipes, indicating blockages or improper drainage

Replacing a roof or repairing major leaks can be costly, so identifying these problems early is a major advantage.

 

3. Assess Windows, Doors & External Walls for Leaks

Heavy rain can reveal how well-sealed a home is against moisture. Pay close attention to:

 

• • Windows and doors – Are they leaking or letting in moisture?
  • External walls – Any water seepage through cracks or poor rendering?
  • Skirting boards – Signs of dampness or water ingress inside the house

Water damage can lead to serious mould issues, structural damage, and costly repairs—things you definitely want to avoid.

 

4. Identify Damp & Mould Risks

Mould thrives in damp conditions, and a rainy inspection will help you identify:

 

• • Damp-smelling rooms – A telltale sign of moisture issues
  • Condensation buildup on windows – Indicating poor ventilation
  • Water stains on walls or ceilings – Possible leaks or rising damp issues

Damp conditions can also lead to pest problems, as termites are drawn to moisture-rich environments.

 

5. Test Outdoor Areas & Features

From decks and patios to driveways and pathways, wet weather is the perfect time to check:

 

• • Surface drainage – Are paved areas or driveways holding water?
  • Slippery surfaces – Some tiles or timber decking become dangerously slick in the rain
  • Outdoor structures – Pergolas, sheds, and fences can all show signs of weather damage

If these areas don’t drain well or become a hazard, it’s worth factoring in the cost of necessary upgrades.

 

6. Ensure the Garage and Under-House Areas Stay Dry

Garages, basements, and under-house storage areas are often prone to flooding or excess moisture buildup. Rain will reveal:

 

• • Leaks in garage roofs or walls
  • Water seepage under roller doors
  • Dampness in under-house storage areas

A flood-prone garage or basement can be a dealbreaker, particularly if you need dry storage space or plan to use it as a workspace.

 

7. Check for Noise Levels in Heavy Rain

If the house has a metal roof, large windows, or a lot of hard surfaces, rain can amplify noise levels. If the sound is overwhelming, you may need to consider insulation upgrades or window treatments to reduce noise inside the home.

 

Final Thoughts: Should You Only Inspect in the Rain?

While a rainy inspection is ideal for spotting hidden defects it is not always possible. But it is goos to inspect a home in different weather conditions if it is possible. If you first view a home on a sunny day, consider returning when it’s raining to check for any issues.
