Slipped or damaged roof coverings
A tile has moved out of line, with a damaged edge interrupting the roof covering. The opening may expose the layers beneath to rain.
Possible explanations
Displacement can follow storm damage or deterioration of the tile and its fixing. An isolated slipped tile does not establish the condition of the whole roof.
What a surveyor examines
A surveyor would consider the surrounding coverings and look for evidence of water entry within an accessible roof space. Closer inspection may be needed to establish how the affected tiles are secured. Staining inside can occur away from the entry point.
Ask WHBC about a drone roof survey to obtain clearer views. Material that appears loose above an entrance warrants prompt assessment and avoidance of the area below.
Defective flashing at a roof abutment
The metal flashing has lifted away from the masonry at the roof junction, leaving an opening along its upper edge.
Possible explanations
The joint securing the flashing may have deteriorated, or previous detailing may allow movement and water entry. Splits in the metal are another possible route. A stain below the junction does not, by itself, identify which detail is leaking.
What a surveyor examines
A surveyor would examine the visible flashing and adjacent masonry, then relate these observations to evidence inside the accessible roof space. Concealed weathering details may need a separately agreed closer inspection.
WHBC can advise whether a drone roof survey would help clarify the visible defects. Establish the water entry route before specifying repairs to this junction.
Deteriorated chimney masonry
Some mortar joints are recessed and the faces of several bricks have broken away near the top of the chimney stack.
Possible explanations
Repeated wetting and frost can damage exposed masonry. The suitability of earlier repairs may also influence how the stack weathers. The appearance alone cannot establish whether its stability is affected.
What a surveyor examines
The surveyor would assess the extent of erosion and look for cracking or leaning. The condition of the chimney pots and their surrounding mortar also needs consideration. Close inspection may be appropriate where a distant view leaves the extent of deterioration uncertain.
Ask WHBC about a drone roof survey. Freshly fallen fragments or visibly loose masonry would justify prompt professional assessment and keeping people away from the area below.
Leaking gutter joint and wall staining
Water is shown escaping at a gutter joint, with a narrow band of staining on the masonry beneath it.
Possible explanations
An open or deteriorated joint may be responsible. Overflow from an obstruction can produce similar staining, so the whole gutter run needs consideration. Persistent wetting may contribute to dampness within the adjoining wall.
What a surveyor examines
A surveyor would examine the joint and how the gutter drains towards its outlet. Observations during rainfall can help distinguish a leak from overflow. Any internal staining should be compared with the external location rather than assumed to have the same cause.
Discuss the affected wall with WHBC through a building survey enquiry. Identifying where the water escapes helps define an appropriate maintenance response.
Stepped cracking near an opening
A crack follows the mortar joints above the corner of a window. Its stepped shape is an observation, not confirmation of subsidence.
Possible explanations
Movement may relate to the support above the opening or changes elsewhere in the building. Seasonal movement and historic settlement also need consideration. Foundation movement is one possibility to investigate in context.
What a surveyor examines
A surveyor would record the crack pattern and width, compare both sides of the wall and consider whether doors or windows have distorted. Previous photographs or monitoring may help establish whether movement continues. An engineer may be needed where structural concerns remain.
Request a WHBC building survey quotation. A crack that is developing rapidly, particularly with new distortion, warrants prompt professional assessment.
Raised ground near the damp proof course
The paving sits close to the horizontal damp proof course in the external wall, leaving little exposed masonry between them.
Possible explanations
Raised paving can increase rain splash above this barrier. Where adjoining material bridges the course, moisture may pass around it. This does not establish that the course itself has failed or that internal dampness comes from the ground.
What a surveyor examines
A surveyor would establish the relationship between outside levels and the internal floor. Drainage falls and any material bridging the course would be assessed alongside corresponding internal symptoms. The floor ventilation openings also need to remain effective.
Ask WHBC about a damp investigation. The appropriate response depends on how moisture reaches the wall and how the surrounding ground drains.
Obstructed ventilation below a timber floor
An air brick is partly covered by soil and vegetation. In this house it serves the void below the suspended timber ground floor.
Possible explanations
Landscaping can obstruct an external opening. Debris or later alterations may also interrupt the air path inside the void. Restricted ventilation can allow moisture to persist, increasing the risk of timber decay where conditions remain damp.
What a surveyor examines
The surveyor would confirm that the openings connect to the floor void and consider airflow across the building. An existing access point may allow inspection of nearby timbers. A clear grille alone does not establish that the concealed air path is effective.
Raise the concern in a WHBC building survey enquiry. Assessment of the ventilation route helps identify what needs attention beneath the floor.
Deterioration to a timber window sill
Paint has flaked from the sill and part of its outer edge appears weathered. The joint at the end is visibly open.
Possible explanations
Repeated wetting through failed finishes or open joints can encourage decay. The extent may be localised, and deterioration at the sill does not automatically mean the complete window requires replacement.
What a surveyor examines
A surveyor would assess the accessible timber and adjoining frame to understand how far the damage extends. The inspection would consider how rainwater is shed and whether nearby defects are keeping the sill wet. Closer examination may distinguish superficial weathering from deeper decay.
A WHBC building survey can help establish the likely extent of the problem and whether a targeted joinery assessment is needed before repairs are specified.
Internal damp staining
An irregular stain is visible on an internal wall, with local damage to the decorative finish. The mark records a symptom rather than its source.
Possible explanations
Rainwater penetration and a plumbing leak are possible explanations. Condensation may contribute in some locations, while an old stain can remain after a leak has stopped. More than one moisture source may be involved.
What a surveyor examines
A surveyor would relate the stain to the construction and conditions outside. The history of the mark and its response to rainfall can help. Moisture readings need interpretation alongside the inspection, with monitoring or targeted investigation where uncertainty remains.
Request a WHBC damp investigation quotation. Establishing the moisture source provides a sound basis for deciding what work is needed.
Surface mould at an external wall corner
Dark speckled growth is visible at an internal corner formed by two external walls. The surrounding finish appears locally affected.
Possible explanations
A colder surface combined with moisture in the air can create conditions for mould. Limited ventilation or a defect that wets the wall may contribute. The pattern should not be attributed to the occupant's behaviour without examining the building.
What a surveyor examines
A surveyor would consider surface temperatures and humidity, together with the available ventilation. The wall construction and signs of water entry would also be assessed. Monitoring can help where conditions vary over time.
Ask WHBC about a damp investigation so that the underlying conditions can be addressed. Extensive or recurring mould warrants prompt attention; decorating alone is unlikely to resolve the cause.
Distortion within the roof structure
The cutaway reveals a bowed roof timber and a slight dip in the roof line. The amount and significance of distortion need assessment.
Possible explanations
Movement can be longstanding. Increased loading from replacement coverings or inadequate support may also be relevant. Where timber has become wet, decay could reduce its ability to carry load.
What a surveyor examines
Within a safely accessible roof space, a surveyor would examine the arrangement of the timbers and their connections. Evidence of alteration and moisture would be considered alongside the external roof profile. A structural engineer may be needed to assess capacity or continuing movement.
Discuss the roof through a WHBC building survey enquiry. Rapidly developing distortion or a broken supporting member justifies prompt professional assessment.
Deterioration affecting floor timbers
The cutaway shows a damaged joist end beside its wall support. In an occupied house, the floor finish may conceal this location.
Possible explanations
Persistent moisture near a bearing can encourage fungal decay. Restricted ventilation may contribute, although a leak or damp masonry could be the moisture source. Discolouration alone would not establish the extent of timber damage.
What a surveyor examines
A surveyor would assess accessible timbers and investigate the conditions within the floor void. Any opening of the floor would need separate agreement where existing access is insufficient. The remaining sound timber and adequacy of its support may require specialist assessment.
Ask WHBC about a building survey. A floor that has become markedly soft or unstable needs prompt assessment, with the affected area kept out of use meanwhile.
