RICS Level 3 Survey Roath Cardiff

The predominantly Victorian and Edwardian construction in Roath presents specific challenges that our surveyors encounter regularly. The solid brick walls, while robust, lack the cavity insulation found in modern properties, and the original damp-proof courses often fail after decades of wear. Many properties have had previous alterations or extensions that may not meet current building regulations, and these can hide structural weaknesses. Our Level 3 Survey is specifically designed to uncover these hidden issues, providing you with a complete picture of the property's condition before you commit to the purchase.

The local geology adds another layer of complexity to property assessments. Roath sits on Mercia Mudstone, a clay-rich bedrock that expands and contracts with moisture changes. This shrink-swell behaviour can cause foundation movement, particularly in properties with mature trees nearby. Our inspectors carefully assess foundation conditions, looking for signs of subsidence or heave that could indicate serious structural problems. The presence of alluvial deposits and glacial till in some areas further complicates ground conditions, and our surveyors know to look for the tell-tale signs of ground-related movement.

The area's conservation status means many properties have historical restrictions that affect what repairs and alterations are possible. Understanding these constraints before you buy is crucial. Our Level 3 Survey includes advice on any listed building or conservation area implications, helping you plan future works with full knowledge of the regulatory requirements. Whether your property falls within the Plasnewydd Conservation Area or the Roath Park Conservation Area, we'll flag any specific considerations in our report.

Roath contains numerous period properties that showcase distinctive architectural features typical of Cardiff's Victorian suburbs. Properties on streets like Marlborough Road, Castle Street, and the surrounding roads often feature decorative brickwork, original sash windows, and bay windows that define the character of the area. These features, while attractive, can conceal defects that only an experienced eye will spot. Our surveyors have identified numerous cases where seemingly solid brickwork was hiding significant penetrating damp, or where original timbers had been compromised by decades of deferred maintenance.

Our comprehensive survey covers every accessible element of the property. We inspect the roof structure, examining slate tiles, flashing, and timbers for signs of deterioration or rot. We assess the walls for cracks, damp penetration, and structural movement. Our inspectors check floor joists, ceiling timbers, and the integrity of load-bearing elements throughout the property. We examine windows, doors, and joinery, noting their condition and functionality.

Given Roath's age profile, we pay particular attention to common defect patterns. Timber decay is frequently encountered, with wet rot and dry rot affecting floor joists and roof timbers in properties that have experienced condensation or roof leaks. Woodworm damage is another common finding in older properties with original timber elements. We also inspect chimney stacks, which are often in poor condition on Victorian terraced houses, with deteriorating brickwork, failed pointing, and corroded lead flashings all regularly identified.

Our surveyors are trained to recognise the specific defects that affect Cardiff's Victorian housing stock. We frequently find issues with original solid brickwork that has suffered from frost damage over the years, particularly on north-facing elevations that receive limited sunlight. Defective gutters and downpipes are a perennial problem, with cast iron systems now often corroded beyond repair. We also check for evidence of previous damp treatments, as many properties in Roath have had chemical damp-proof courses injected, sometimes incorrectly or in conjunction with failed physical membranes.

Terraced properties dominate the Roath housing market, making up nearly 60% of the housing stock. These Victorian and Edwardian terraces often have original features that require careful assessment. Bay windows, decorative brickwork, and original sash windows are characteristic of the area, but they can also conceal hidden defects. Our surveyors examine these period features thoroughly, identifying where maintenance is needed and where original elements have been inappropriately modified. The typical Roath terrace will have solid brick walls, a pitched slate roof, and suspended timber floors, all of which have specific defect patterns our inspectors recognise.

Flats and maisonettes account for around 32% of properties in Roath, with many converted from larger Victorian houses. These conversions often present specific issues related to shared structures, leasehold arrangements, and the condition of common areas. Our Level 3 Survey can be tailored to flat requirements, assessing the individual unit as well as flagging any issues visible within the property that may relate to the wider building. We check the condition of shared walls, floors, and ceilings, and note any alterations that may have compromised structural integrity.

Semi-detached and detached properties are less common in Roath, comprising only about 8% of the housing stock. These properties were often built as individual commissions during the Victorian and Edwardian periods, meaning they can vary significantly in construction and condition. Larger properties may have more complex structural elements, including multiple roof slopes, larger spans, and more extensive foundations that require detailed assessment. The higher price points for detached properties in Roath, averaging around £455,000, make the investment in a thorough survey particularly worthwhile.

The Plasnewydd ward, which covers much of Roath, has a population of over 19,000 residents across more than 8,000 households. This dense urban environment means many properties are semi-detached or have very limited gardens, with boundary walls and shared access ways that require specific assessment. Our surveyors understand these urban constraints and know how to assess properties where access may be restricted by neighbouring buildings or where the condition of adjoining walls needs careful evaluation.

The geology beneath Roath creates specific considerations for property owners. The alluvial deposits and glacial till overlying Mercia Mudstone mean the ground has moderate to high shrink-swell potential. During extended dry periods or following significant rainfall, clay soils beneath properties can expand and contract, putting stress on foundations. Our inspectors look for evidence of this movement, including diagonal cracks at corners, doors that stick, and uneven floors. Properties with large trees close to the building are particularly at risk, as tree roots extract moisture from the clay, causing it to shrink.

Flood risk in Roath is primarily from surface water, with the Roath Brook and urban drainage systems sometimes struggling during heavy rainfall. Properties in lower-lying areas or those near the brook may have experienced previous flooding. Our survey includes assessment of flood risk indicators, checking for water staining, flood resilience measures, and the condition of lower-level fixtures and finishes. We note any drainage issues visible externally and advise on potential improvements that may be needed.

While Roath is not in a coal mining area, properties in this suburb may have other ground-related issues. Made ground from historical development, backfilled cellars, and variations in foundation depth across adjacent properties can all create challenges. Our surveyors are familiar with these local ground conditions and know what to look for when assessing Roath properties. We examine external ground levels, check for evidence of cellar voids, and assess the overall stability of the property's foundation system.

The Roath Brook flows through several parts of the suburb, and properties in its vicinity face particular attention during our inspection. We've surveyed properties on streets close to the brook where previous flooding has caused damage to lower floors, displaced skirting boards, and left tell-tale watermarks on walls. Our report will highlight any flood risk and recommend appropriate investigations, including checking the condition of any existing flood resilience measures that may have been installed.

The vast majority of Roath's housing stock was constructed before 1919, with most Victorian terraces built using traditional solid brick wall construction. These walls, typically 225mm to 330mm thick, were laid with lime mortar rather than modern cement, which allows some breathability but can deteriorate over time. Our inspectors assess the condition of pointing, looking for eroded mortar joints that allow water penetration, and check whether sympathetic repointing with lime mortar has been carried out where needed.

Roof construction in Roath's period properties typically consists of timber rafters with sarking boards and natural slate or clay tile coverings. Many original slate roofs have now exceeded their expected lifespan, with individual tiles becoming porous or slipping. Our surveyors access the roof space where possible to assess the condition of felt, sarking, and structural timbers. We've found numerous cases of timber rot in roof spaces caused by prolonged roof covering failures that allowed water ingress over many years.

The suspended timber floors found in most Victorian Roath properties present their own inspection challenges. These floors were typically constructed with timber joists spanning between internal load-bearing walls, with air bricks providing sub-floor ventilation. In our experience, these air bricks are frequently blocked by vegetation, debris, or even rendered over during redecorations, leading to increased moisture levels and subsequent timber decay. We inspect under floor void spaces where access is available and use moisture meters to identify areas of elevated dampness that may indicate inadequate ventilation.
