Essential Insights from a Building Surveyor for Your Next Property Viewing

When property investors attend viewings, they often focus on aesthetics and location. Yet, the condition of the building plays a crucial role in determining the true value and potential risks of the investment. A building surveyor’s mindset offers a practical edge, helping investors spot issues that could affect future costs or negotiations. This guide highlights the top five things to look out for during property viewings, drawing on the expertise of building surveying professionals.

Inspecting the roof condition during property viewing

Check the Roof Thoroughly

The roof is one of the most critical components of any property. It protects the structure from weather damage and affects energy efficiency. During a viewing, look for:

• Missing, cracked, or slipped tiles

• Signs of water damage or stains on ceilings inside the property

• Sagging or uneven rooflines

• Condition of gutters and downpipes, ensuring they are clear and intact

  
  

A damaged roof can lead to costly repairs and may indicate underlying issues with the building’s construction. If the roof shows signs of wear, ask for recent maintenance records or surveys to understand the extent of any problems.

Assess the Structural Condition

Structural issues can be hidden but have serious implications. Investors should look for:

• Cracks in walls, especially around windows and doors

• Uneven floors or doors that stick or don’t close properly

• Damp patches or mold, which may suggest rising damp or leaks

• Signs of subsidence such as gaps between walls and ceilings

  
  

These signs often point to foundational problems or poor construction quality. A building surveyor would recommend a detailed structural survey if any of these symptoms appear, as they can affect the safety and value of the property.

Inspect the Electrics and Plumbing

Electrical and plumbing systems are expensive to upgrade if outdated or faulty. During property viewings, check:

• Condition of visible wiring and sockets; look for exposed wires or scorch marks

• Age and type of the fuse box or consumer unit

• Water pressure and drainage by running taps and flushing toilets

• Signs of leaks under sinks or around boilers

  
  

Faulty electrics or plumbing can delay deals and add unexpected costs. Requesting a recent electrical installation condition report or plumbing inspection can save surprises later.

Evaluate the Quality of Construction Materials

The materials used in the building’s construction affect durability and maintenance needs. Investors should pay attention to:

• Type of walls (solid brick, cavity, timber frame) and their condition

• Quality of windows and doors, including seals and frames

• Flooring materials and any visible damage or wear

• Insulation presence and condition, especially in older properties

  
  

Poor-quality materials or outdated construction methods can lead to higher running costs and reduced lifespan. Building surveying reports often highlight these issues, helping investors negotiate better deals or plan future upgrades.

Review Previous Surveys and Documentation

If available, reviewing past surveys and maintenance records provides valuable insight into the property’s history. Look for:

• Recent building surveys or condition reports

• Records of repairs, renovations, or extensions

• Energy performance certificates (EPCs)

• Planning permissions and compliance certificates

  
  

These documents help verify the property’s condition and legal standing. They also support informed decisions and strengthen negotiating positions during deals.

Understanding these five key areas during property viewings equips investors with the knowledge to spot potential problems early. Building surveying expertise reveals hidden risks that can affect the property's value and future costs. Taking time to inspect the roof, structure, electrics, construction materials, and documentation ensures smarter investments and smoother transactions.
