Buying a home is one of the biggest financial decisions most people will ever make. While it’s easy to focus on the layout, location, and appearance of a property, it’s equally important to look beyond the cosmetic features. Many expensive building problems aren’t obvious during a quick inspection or home open.
Before making an offer on a house, taking a closer look at a few key areas can help you identify potential issues and decide whether a professional building inspection is needed.
1. Check the Gutters and Downpipes
Gutters and downpipes play a vital role in protecting a home from water damage. Look for signs of rust, sagging, loose brackets, overflowing sections, or evidence of previous repairs.
Poorly maintained gutters can cause water to pool around the foundations, increasing the risk of structural movement, dampness, and costly repairs.
2. Look Along the Roofline
Stand back and view the roof from different angles. A roofline should appear relatively straight and even.
Watch for:
- Sagging sections
- Missing or damaged roof tiles
- Rust on metal roofing
- Damaged flashing
- Uneven ridgelines
Roof problems can sometimes indicate underlying structural issues or long-term water damage.
3. Inspect the Ceilings Inside
Ceilings often reveal signs of hidden issues that may not be immediately obvious elsewhere.
Look for:
- Water stains
- Discoloured patches
- Bubbling paint
- Cracks
- Sagging plaster
These signs may indicate roof leaks, plumbing problems, or movement within the structure.
4. Test Every Door and Window
Open and close as many doors and windows as possible during your inspection.
Difficulty opening or closing them can sometimes suggest:
- Foundation movement
- Structural settling
- Warped frames
- Moisture damage
While sticking doors aren’t always a major concern, they should be investigated further if accompanied by cracking or uneven floors.
5. Examine Retaining Walls
Retaining walls can be expensive to repair or replace if they begin to fail.
Look for:
- Leaning walls
- Bulging sections
- Large cracks
- Poor drainage behind the wall
- Movement in nearby paving
Failing retaining walls may also affect neighbouring structures and boundary fences.
6. Look for Signs of Poor Drainage
Water should always drain away from the home.
Watch for:
- Pooling water
- Soil erosion
- Damp garden beds against walls
- Overflowing gutters
- Water stains on external walls
Poor drainage can contribute to foundation movement, rising damp, mould growth, and landscaping problems over time.
7. Check for Cracks Throughout the Property
Not all cracks are serious, but some deserve closer attention.
Pay particular attention to:
- Large diagonal cracks
- Cracks around doors and windows
- Wide brickwork cracks
- Cracks that continue through multiple walls
- Uneven floor levels
A professional building inspector can determine whether cracking is cosmetic or potentially structural.
8. Don’t Be Distracted by Fresh Paint
Fresh paint and stylish renovations can make a home look immaculate, but cosmetic improvements may sometimes hide underlying defects.
Take the time to inspect areas carefully rather than assuming a freshly renovated property is problem-free. If access is available, check inside cupboards, behind doors, and around wet areas for signs of moisture, movement, or poor workmanship.
Why a Professional Building Inspection Matters
Even experienced buyers can miss important defects during a home open. A professional building inspection provides an independent assessment of the property’s condition and can identify issues that aren’t immediately visible.
A comprehensive inspection may uncover structural concerns, moisture problems, roof defects, drainage issues, or other maintenance items that could influence your purchasing decision or provide valuable negotiating power before contracts become unconditional.

Our comprehensive reports help buyers make informed decisions with confidence, giving you a clear understanding of the property’s condition before you commit to one of life’s biggest investments.
If you’re considering purchasing a property, booking a professional inspection could save you thousands of dollars in unexpected repair costs and provide valuable peace of mind.
