Heritage Aerial Intelligence for Historic Buildings
Historic buildings rarely reveal their full condition from ground level. Roof defects, failing leadwork, blocked rainwater systems and masonry deterioration can remain unseen for years, allowing minor issues to develop into significant conservation challenges.

Protect What's Valued
Our independent aerial intelligence helps custodians, trustees, conservation professionals and insurers understand building condition, prioritise maintenance and protect historic fabric without intrusive access or unnecessary disruption.

What Historic Buildings Can Hide
Many heritage buildings contain high-level defects that cannot be safely or effectively assessed from ground level alone. Early identification allows custodians to prioritise repairs, reduce long-term costs and safeguard historic fabric before deterioration becomes more extensive.
Drone inspections provide a safe method of understanding condition without the immediate need for scaffolding.

“Three Weave provided us with over 300 high quality images on the first external survey - which enabled us to look closely at the condition of the building particularly the roof which, of course, is hard to see in detail from the ground. The images can be zoomed in to focus clearly on specific areas of concern which has proved helpful in scheduling and prioritising maintenance. The survey was unobtrusive - a lot quieter than I was expecting- and was easy to arrange” - Church Warden - St.Thomas Church, Garstang

Supporting Those Responsible
for Historic Buildings
Historic buildings are cared for by a wide range of owners, custodians and professionals, each with different responsibilities and priorities. Our heritage drone inspections and aerial surveys provide independent visual evidence to support informed decision-making across the built heritage sector.

We regularly support:

Providing aerial inspections of churches, chapels, towers and spires to help identify defects, support maintenance planning and document building condition.

Helping owners understand roof condition, identify hidden defects and prioritise maintenance while protecting historic fabric.

Supporting estate managers and custodians responsible for the long-term stewardship of significant historic assets.

Supporting conservation architects, surveyors and specialists with high-resolution imagery and aerial intelligence for difficult-to-access areas.

Helping those responsible for day-to-day building management understand emerging risks and plan preventative maintenance.

Providing independent aerial evidence to support underwriting, claims investigations, risk assessments and post-event inspections.

What We Inspect During a Heritage Drone Survey
Every historic building is different. Our heritage drone inspections are tailored to the individual property, its construction, significance and maintenance objectives.
Roof Coverings
Slates, tiles, ridge details, parapets and other roof elements.
Lead Roofs & Flashing
Lead coverings, valleys, gutters, abutments and associated details.
Church Towers & Spires
High-level structures that are difficult, costly or hazardous to inspect.
Rainwater Goods
Gutters, hopper heads, downpipes and drainage arrangements.
Masonry & Stonework
Stone façades, decorative detailing, pointing, weathering and signs of deterioration.
Chimneys, High Features
Assessing condition and identifying defects affecting stability or water ingress.
Vegetation Growth
Identifying moss, invasive growth and biological colonisation that may accelerate deterioration.
Roof Drainage
Locating blockages, overflow points and areas where poor water management may be affecting historic fabric.
Storm Damage
Providing rapid post-event inspections following severe weather to identify damage and support insurance discussions.
Inaccessible Areas
Safely inspecting locations where traditional access methods may be impractical or prohibitively expensive.


Grant and Funding Applications
High-resolution imagery and documented observations can provide valuable supporting evidence when seeking funding for repair and conservation projects.
Planned Preventative Maintenance
Early identification of defects helps prioritise repairs before deterioration becomes more extensive and costly.
Post-Loss & Storm Damage Assessment
Drones can assess landscapes, wildlife impact, drainage, and surrounding risks with precise aerial environmental analysis.
Conservation Planning
Detailed visual evidence assists conservation professionals and custodians in understanding building condition and planning appropriate interventions.
Committee & Trustee Reporting
Clear visual evidence helps trustees, PCCs, committees and stakeholders understand building condition and agree priorities.
Insurance Risk Management
Independent aerial evidence can support underwriting discussions, renewal reviews and broader risk management activities.
Long-Term Condition Monitoring
Repeat inspections create a visual record of change over time, helping organisations demonstrate stewardship and monitor deterioration trends.
Supporting Better Heritage Decisions
Our role is not simply to capture aerial imagery. We provide independent aerial intelligence that helps those responsible for historic buildings make informed decisions.
Heritage aerial evidence reports can support:

We have developed a growing collection of practical guidance to help custodians, trustees, conservation professionals and insurers better understand the risks affecting heritage properties and how using drone inspections can help.
Heritage Guidance
Practical articles covering common defects, maintenance planning and approaches to protecting historic buildings.
Risk Guides
Understand how defects such as failing leadwork, blocked gutters, slipped slates and masonry deterioration develop — and why early identification matters.
Insurance Guidance
Resources explaining how aerial evidence can support risk management, underwriting and claims investigations for heritage properties.

Protect Your Historic Building with Confidence
Every historic building deserves informed stewardship.
Whether you are responsible for a listed building, church, heritage estate or other significant historic property, understanding its condition is the first step towards protecting it for future generations.
Three Weave provides independent heritage drone inspections that help custodians, conservation professionals and insurers make informed decisions based on clear visual evidence rather than assumption.
