Survey for a Bungalow: What Surveyors Check and Why It Matters

Buying a Property

By Lyman Marshall, Chartered Surveyor MRICS · Published September 2026 · Updated September 2026

Most UK bungalows were built between the 1960s and 1980s — and that age profile matters more than most buyers realise. A survey for a bungalow covers the same fundamentals as any other residential property survey, but surveyors bring a different checklist to a single-storey home. The structural risks are distinct, the roof carries far greater significance, and the lower ground clearance creates specific damp risks you won't find in a terraced or semi-detached house.

Why Bungalow Surveys Are Different

In a two-storey house, the roof load spreads across two floor levels before reaching the foundations. In a bungalow, all of that weight travels directly to the perimeter walls and footings — with no upper floor to help distribute it.

That single structural difference has a ripple effect on how a bungalow ages. It makes roof spread more likely, increases the load on external walls, and puts more pressure on foundations in areas with clay-rich soils — including much of Lincolnshire and Nottinghamshire. Surveyors look harder at those load paths than they would on a two-storey property.

Add to that the fact that bungalows sit closer to ground level than most property types — which increases exposure to rising damp — and the case for a systematic, thorough inspection starts to become clear.

What a Surveyor Checks in a Bungalow

The Roof Structure

The roof is one of the most critical elements of any bungalow survey. Surveyors inspect the pitch, covering material, and condition of all visible roof elements — ridge, hips, valleys, verges, and eaves. Where access is possible, they enter the loft space to check the timber frame, assess for sagging or spreading, and look at whether tie rods or collar beams are in place and working correctly.

Roof spread is a particular concern. This is the outward movement of external walls caused by the weight of the roof pushing against them over time. Early signs include cracking at ceiling junctions, gaps around window frames, and visible wall lean. Remedial work typically costs between £3,000 and £12,000 depending on bungalow size and access, making it one of the costlier defects to miss at the point of purchase.

Flat and Low-Pitch Roofs

Many bungalows built in the 1970s and early 1980s have flat or low-pitched roof sections, often over extensions or utility areas. These are among the most common sources of water ingress identified in surveys. Surveyors check the drainage falls, condition of the covering material, flashings, and junctions with vertical walls. A flat roof section that needs recovering may cost £2,000–£5,000 for an average bungalow extension — a figure worth knowing before exchange.

External Walls and Foundations

Because all structural loads concentrate on the external walls, surveyors check them carefully for cracking patterns, bowing, and signs of movement. Diagonal cracks at corners and around openings can indicate differential settlement. In areas of clay soil — which covers much of Lincolnshire and Nottinghamshire — seasonal ground movement is a known cause of subsidence. Surveyors look for the characteristic tapered cracking and assess whether any significant trees are nearby.

Rising Damp and Moisture

Bungalows sit closer to ground level than most property types, which increases the risk of moisture rising through walls and floors. Older bungalows often have solid floors with limited or deteriorating damp-proof courses. Surveyors use moisture metres to check wall readings at low level, assess whether the DPC is bridged by external ground or rendering, and look for tide-mark staining or salt crystallisation associated with rising damp.

Condensation is also common. Single-storey living concentrates moisture-generating activities — cooking, bathing, laundry — within a compact space, and older bungalows often have inadequate ventilation. Evidence of condensation is not the same as rising damp, but both can cause lasting damage to wall finishes and timber elements if left untreated.

Extensions, Garages, and Conversions

Bungalows are frequently extended. Rear additions, conservatories, converted garages, and altered loft spaces are all common — and some are built to a higher standard than others. Surveyors check the junction between the original structure and any addition, since differential movement often shows there first. Loft conversions deserve particular attention: converting a roof space changes the load distribution and can affect the structural frame if not properly engineered.

Which Survey Level Do You Need for a Bungalow?

The right level depends on the age, condition, and complexity of the property. As a general guide:

Survey Level	Best For	What It Covers
RICS Level 2 (HomeBuyer Survey)	Modern or well-maintained bungalows built after 1990 in clearly good condition	Visual inspection using a traffic-light condition rating. Highlights urgent defects and maintenance needs.
RICS Level 3 (Building Survey)	Older bungalows (pre-1990), extended properties, those with visible or suspected defects	Full structural inspection covering construction methods, advice on repairs, and cost guidance where relevant.

For most bungalows built before 1990 — which covers the majority of UK stock — a RICS Level 3 Building Survey is usually the more appropriate choice. The combination of single-storey structural dynamics, age-related roof issues, and the higher likelihood of extensions means a more detailed investigation is worth having. If the property is post-1990 and in clearly good condition, a Level 2 survey may be sufficient — and your surveyor can advise once they've seen the property.

Common Defects Found in Bungalow Surveys

Based on properties we survey across Lincolnshire, Nottinghamshire, and the surrounding region, the defects most commonly flagged in bungalow reports include:

• Roof spread (outward wall movement caused by concentrated roof weight)
• Flat roof deterioration and water ingress at flashings or edge details
• Rising damp through solid floors or bridged damp-proof courses
• Subsidence or settlement in clay-soil areas, particularly near mature trees
• Poor-quality or unapproved extensions and garage conversions
• Deteriorating cavity wall insulation in 1970s–1980s construction
• Outdated wiring or heating systems nearing end of service life
• Condensation damage in bathrooms, kitchens, and loft spaces

Not all of these defects are deal-breakers. Many are manageable with the right repair programme and an appropriate budget. The value of a survey is knowing which ones you're dealing with before you commit to a purchase price — not after.

What Happens After a Bungalow Survey?

If the survey identifies significant defects, you have options: proceed at the agreed price, renegotiate based on estimated repair costs, request the seller to carry out work before exchange, or in serious cases, withdraw. Having a RICS report gives you documented evidence that supports any negotiation in a way that an informal viewing simply cannot.

Where a surveyor recommends further specialist investigation — a structural engineer's report on roof spread, or an independent damp specialist's opinion — it's worth arranging these before exchange rather than after, so any findings can still influence the terms of your purchase.
