Roof and façade condition monitoring

Create a dated record of your roof or external walls and use repeat inspections to identify visible changes that need attention.

Make changes easier to identify

A photograph taken at one visit records condition at that point. A planned sequence of inspections allows accessible details to be compared over time, helping owners decide when maintenance or further investigation should be commissioned.

WHBC can establish an initial visual record and return at agreed intervals. Drone imagery may assist where the site and operating conditions allow. The inspection method is chosen for the question being monitored, with access limitations explained in the reporting.

A repeatable visual inspection record

  • Initial condition record: identify the areas to be monitored and photograph accessible roof or façade details.
  • Inspection planning: agree a repeat inspection interval and the circumstances that should trigger an earlier review.
  • Comparison visits: record visible changes using consistent locations and viewpoints where practicable.
  • Action reporting: explain findings requiring repair or closer investigation and draw attention to newly observed concerns.

What you receive

A dated photographic record establishes the starting condition within the agreed scope. Subsequent reports compare the areas inspected and update the action schedule. The reports identify changes seen and record any difference in access or viewing conditions that limits comparison. A separate scope can be developed for resulting repairs.

Example scenario: monitoring an ageing roof

For example, an owner planning future roof renewal could commission an initial visual survey and agreed follow up visits. Comparisons might identify further slipped coverings or changes at a roof junction, allowing the owner to commission repairs or bring forward a more detailed investigation.

Questions about this service

The interval depends on the building condition and the purpose of monitoring. We discuss the available information before proposing a programme. Where a specialist has advised particular inspection requirements, those need to be incorporated into the brief.

No. It records visible condition at the inspection dates and does not provide a structural guarantee. Concealed defects or movement may require testing or a structural engineer’s assessment. Monitoring is not a substitute for dealing with an identified immediate concern.

Drone use depends on site restrictions and suitable operating conditions at each visit. We agree an appropriate inspection method and report any areas that could not be viewed. A change in method may affect how directly the photographs can be compared.

Repeat photographs can record visible changes but are not automatically a precise movement measurement system. If measured movement monitoring is required, the equipment and interpretation responsibilities need a separately agreed specialist scope.
