4. ISO-Compliant Report
You receive a PDF Report + 4K video + gutter mapping for insurers, builders, or facilities managers.
The "Regeneration Guarantee"
For new builds at The Works, we provide a post-warranty defect log. If no actionable issues are found within 2 years of build, you pay only 50%.
*Disclaimer: Rescheduled visits are billed at the original quoted rate.
FROM HERITAGE TO HIGH-TECH
One drone. Two worlds.
Ebbw Vale is a tale of two roofs: The Works’ modern builds with GRP systems and Beaufort’s aging terraces with chronic damp.
We bridge both with precision:
- ✅ ISO 19650 Compliance: Structured data for commercial clients
- ✅ Rassau Industrial: Gutter & cladding audits for logistics units
- ✅ Beaufort Damp Mapping: Hidden valley gutter blockages
Ebbw Vale: Industrial Spans and Post-Industrial Housing
From The Works regeneration site to the steelworks terraces at Cwm and Beaufort.
Large Spans at The Works and Rassau
Regeneration at The Works and the units on Rassau Industrial Estate mean acres of profiled sheeting, long valley gutters and translucent rooflights. The rooflights are the specific hazard: they degrade until they will not carry weight, and they look identical to the sheet beside them. Flying the roof removes any need to find that out the hard way.
Steelworks-Era Housing Stock
The terraces at Cwm, Waunlwyd and Beaufort were built for the works and largely retain their original roof structures. Sustained upland wind plus a century of service produces slipped slate, opened laps and perished lead at the stack. It stays a maintenance problem rather than a replacement problem only if somebody looks in time.
Measured Data for Development Sites
Ebbw Vale has live development and remediation land. Beyond roof condition we produce measured aerial data: orthomosaics, stockpile and cut-fill volumes, and dated progress records. That serves contractors and planners working the regeneration sites for far less than mobilising a ground survey team for every update.
A Fixed Fee, Whatever We Find
CalonTerra is a survey business, not a roofing or maintenance contractor, so nothing in an Ebbw Vale report leads to a quote from us. You get the imagery, the 4K video and a written assessment at a price agreed beforehand, then take it to whichever contractor or insurer you prefer.
Buying in The Works?
"The developer’s warranty expires in 3 months."
New builds often have hidden installation defects: poor GRP falls, unsealed junctions, missing vents.
The Solution: An ISO-compliant drone audit that gives you leverage before warranty expiry.
Rassau Industrial Estates
Logistics units require routine roof health checks.
- ✅ Flat Roof Mapping: Identify ponding and split seams
- ✅ Gutter Blockages: Map debris across large roof networks
- ✅ Compliance Ready: Full audit trails for BSI or insurer review
Typical Defects We Expose
GRP Roof Ponding
Poor falls on new builds cause standing water. Critical for insurance claims.
Beaufort Damp Sources
Hidden valley gutters between terraces cause chronic internal damp.
Rassau Cladding Failure
Corrosion and panel displacement on logistics units and warehouses.
Post-Warranty Ventilation
Missing or blocked roof vents causing condensation in attic spaces.
Ebbw Vale Construction Intelligence
Our drones are calibrated to spot specific defects common to the Regeneration Hub:
- The Works: GRP flat roofs, modern tile systems, unsealed junctions
- Rassau Estate: Industrial cladding, aluminium guttering, thermal loss
- Beaufort: Victorian terraces, valley gutter networks, rear chimney stacks
- ISO 19650: Structured, compliant data output for commercial clients

Ebbw Vale Drone Surveys: NP23 Questions
What Ebbw Vale, Cwm, Beaufort and Rassau customers ask us.
Can you survey a large industrial roof without anyone walking on it?
That is the main reason industrial clients call. Profiled sheeting and ageing rooflights are among the most common causes of serious falls in building maintenance. We record sheet corrosion, fixing condition, gutter blockage and rooflight degradation from the air, with nobody at height at all.
Do you produce measured survey data as well as photographs?
Yes. Alongside condition imagery we deliver orthomosaic mapping, digital terrain models and volumetric calculations, which is what development and remediation work around The Works generally needs. The measured side of our work is set out on our topographical mapping page.
Is Ebbw Vale too high and windy for a reliable booking?
It is exposed, so we build flexibility into the schedule and watch the forecast for the tops rather than the valley floor. If we arrive and conditions prevent a safe or useful flight, there is no charge and we rebook at the originally quoted rate.
Can you inspect a terraced house as well as commercial premises?
Yes. Domestic work at Cwm, Waunlwyd, Beaufort and Ebbw Vale town is routine, and the terraced streets here are where the aircraft is most useful, because the rear elevations are difficult and expensive to reach any other way.
How is the price worked out from Pontypool?
The survey fee plus travel from our NP4 base is calculated for your specific postcode in the quote form on this page. You see the complete figure before committing, and payment is taken on arrival once the flight is confirmed safe.
