Top 5 issues found during residential building surveys
When purchasing a property, it’s natural to wonder what a building survey might uncover. While every property is different, there are certain issues that come up regularly during residential surveys.
Understanding these common findings can help you approach the process with realistic expectations and a clearer idea of what to look out for.
1. Roof defects
The roof is one of the most frequently reported areas in any building survey.
Common issues include:
Slipped or missing tiles
Deteriorated roof coverings
Defective flashing around chimneys or junctions
Signs of ageing or previous repairs
Many of these issues develop gradually and are not always visible from the ground. While not always urgent, roof defects can lead to more significant problems if left unaddressed.
2. Damp and moisture-related issues
Damp is another common finding, particularly in older properties.
Typical causes include:
Poor ventilation leading to condensation
Defective rainwater goods
Bridged damp-proof courses
External ground levels that are too high
A building survey helps identify not just the presence of moisture, but the likely cause, which is key to resolving the issue properly.
3. Cracking and movement
Cracks in walls are often highlighted during surveys but they vary significantly in severity.
In many cases, cracking is:
Minor and related to normal settlement
Historic and no longer active
However, surveys also assess whether there are signs of ongoing movement that may require further investigation.
Understanding the context of cracking is essential, rather than focusing on appearance alone.
4. Poor maintenance
A lack of routine maintenance is one of the most common underlying issues found during surveys.
This can include:
Blocked gutters and downpipes
Deteriorated external finishes
Worn seals around windows and doors
General neglect of smaller defects
Individually, these issues may seem minor, but collectively they can affect the condition and performance of the property.
5. Previous alterations
Many properties have been altered over time, and not all work is carried out to a high standard.
Surveys often identify:
Removed or altered internal walls
Loft conversions
Extensions or modifications
Inconsistent workmanship
The focus is not just on what has been changed, but whether those changes may affect the structure or long-term performance of the building.
What these findings mean for buyers
It’s important to recognise that most properties will have some issues. A building survey is not about finding a “perfect” property, but about understanding its condition.
In many cases, the issues identified are:
Manageable through routine maintenance
Typical for the type and age of the property
Useful for planning future works
Only occasionally do surveys uncover serious defects requiring immediate attention.
Final thoughts
Residential building surveys provide valuable insight into the condition of a property. By identifying common issues such as roof defects, damp, cracking, maintenance concerns and past alterations, they help buyers make informed decisions.
Rather than being a cause for concern, a survey should be seen as a tool to understand the property and plan ahead with confidence.
