Using Aerial Inspections to Plan Maintenance
Building maintenance is most effective when it is planned, proportionate, and based on evidence. Many of the most disruptive and costly building issues arise when deterioration goes unnoticed until urgent intervention is required.
Aerial inspections support a preventative approach by providing clear, visual information about parts of a building that are difficult to inspect safely or regularly. When used over time, they help property owners, custodians, and operators plan maintenance rather than react to failure.
This guidance explains how aerial inspections can be used as part of a structured maintenance strategy.
The difference between planned and reactive maintenance
Reactive maintenance often occurs when:
-
Water ingress becomes visible internally
-
Elements fail during severe weather
-
Emergency access or temporary works are required
Planned maintenance, by contrast, is based on early identification and prioritisation, allowing issues to be addressed before they become urgent.
Aerial inspections provide information that supports this shift.
How aerial inspections support maintenance planning
Aerial inspections focus on building elements that are:
-
Highly exposed to weather
-
Difficult or unsafe to access
-
Often overlooked during routine checks
By observing these areas regularly, aerial inspections help to:
-
Identify early signs of deterioration
-
Confirm whether known issues are stable or worsening
-
Provide visual evidence to support decisions
This information allows maintenance to be scheduled at appropriate times and budgets to be planned more effectively.
Using inspections as part of a maintenance cycle
Aerial inspections are most effective when integrated into a broader maintenance cycle.
This may include:
-
Routine ground-level checks
-
Periodic professional surveys
-
Targeted access where required
Aerial inspections sit between these activities, providing a light-touch, repeatable overview of high-level condition.
Prioritising maintenance activities
Inspection findings help to distinguish between:
-
Issues that require monitoring
-
Issues that warrant further investigation
-
Issues that may require planned intervention
This prioritisation helps avoid unnecessary work while ensuring genuine risks are not overlooked.
Supporting budgeting and long-term planning
Visual records from aerial inspections can support:
-
Maintenance forecasting
-
Budget discussions with stakeholders
-
Phased repair planning
For organisations and custodians, this evidence-based approach supports transparency and accountability.
Reducing emergency access and disruption
Emergency repairs often involve:
-
Short-notice scaffolding
-
Temporary closures or disruption
-
Higher costs and limited contractor choice
By identifying issues earlier, aerial inspections reduce the likelihood of emergency access and allow works to be planned around occupancy, events, or trading periods.
Working with professional advisers and contractors
Aerial inspection reports provide useful context for:
-
Surveyors and engineers assessing risk
-
Conservation professionals planning investigations
-
Contractors pricing targeted access or repairs
They support informed discussion but do not replace professional judgement or hands-on investigation.
Understanding the limits of preventative inspection
While aerial inspections support maintenance planning, they are not predictive or diagnostic.
They:
-
Record visible condition at a point in time
-
Cannot detect concealed defects
-
Should be used alongside professional advice
Understanding these limits ensures inspections are used appropriately.
