The Navigation & Engineering Hub
From Crumlin’s industrial heritage to Risca’s steep residential valleys.
1. Topographical Assessment
We assess slope angle and access risk. If it’s too steep for ladders, it’s perfect for drones.
2. Arrive & Pay
Accept the quote to book. To prevent fraud, payment is only taken upon arrival once flight safety is confirmed.
3. The 20-Min Scan
We use stabilized drones to inspect extreme slopes safely. Ideal for A470 corridor properties.
4. Receive Data Package
You receive a PDF Condition Report and a link to every raw image & 4K video to show your insurer or engineer.
The "Impossible Access" Guarantee
If your property has a slope steeper than 30 degrees or is adjacent to industrial infrastructure, ladders are unsafe. We provide the only viable inspection method. If we cannot fly due to terrain, you do not pay a penny.
*Disclaimer: Rescheduled visits are billed at the original quoted rate.
TAMING THE INCLINE
Drones are the only safe way.
Inspecting a roof in Crumlin often means working on a 45-degree valley slope. Ladders are unstable; scaffolding is prohibitively expensive.
Our drone survey eliminates all physical risk:
- ✅ Industrial Heritage Sites: Crumlin Navigation area mapping
- ✅ Valley-Side Safety: No personnel on steep slopes
- ✅ A470 Corridor Access: Rapid deployment for impossible sites
Crumlin: Inspecting a Roof on a One-in-Three Hillside
The Ebbw valley sides at Crumlin, Newbridge and Abercarn make conventional access marginal.
Gradients That Defeat Ladders
The streets climbing from the valley floor at Crumlin and Newbridge sit on slopes steep enough that a ladder cannot be footed safely at the rear of a property. That is not a preference, it is a working-at-height problem — and it is why so many roofs here have never truly been inspected, only guessed at from the pavement.
Industrial Heritage Structures
Crumlin's legacy is large: former works buildings, retaining structures and the remains of the viaduct approaches. Structures like these need condition monitoring in places nobody can safely stand. We photograph them at zoom from a stable hover, and can repeat identical angles later to show whether anything has moved.
Valley Floor Damp, Hillside Wind
Two different climates inside half a mile. Properties on the floor near the Ebbw hold moisture, grow moss and lose mortar; properties up the valley side take uplift at the ridge and verge. What a survey should be looking for depends on where in Crumlin you actually are, and we plan the flight around that.
The Report Is the Product
We do not repair roofs, so nothing we find in Crumlin turns into work for us. Fixed fee, every raw image, the 4K video and a written condition assessment — then you decide whether to call a roofer, call your insurer, or do nothing at all because the roof is sound.
Owning a Valley-Side Home in Crumlin?
"The roofer said it's too dangerous to inspect."
Steep slopes and limited rear access make traditional inspections unsafe or impossible.
The Solution: Aerial evidence without setting foot on your property.
Industrial & Heritage Audits
The Crumlin Navigation area demands non-intrusive inspection methods.
- ✅ Asbestos Roofing (Visual): Safe identification
- ✅ Structural Mapping: For aging engineering sites
- ✅ Thermal Option: Detect heat loss on converted units
Typical Defects We Expose
Steep-Pitch Tile Slippage
Identify slipped or missing slates on 40°+ roofs. Critical for Trace and Access.
Industrial Chimney Erosion
Check for lead flashing issues and cracked pointing on tall stacks.
Valley Gutter Blockages
Spot vegetation growth and sagging brackets from above.
Water Ingress on Slopes
Identify driving rain penetration on exposed eaves.
Crumlin Engineering Intelligence
Our drones are calibrated to spot specific defects common to the Western Valley:
- Crumlin Navigation: Industrial heritage mapping
- A470 Corridor: Rapid response for commercial sites
- Risca Slopes: Valley-side water ingress patterns
- Newbridge Estates: 1970s concrete tile audits

Crumlin Drone Surveys: NP11 Questions
What Crumlin, Newbridge and Abercarn residents ask us.
My back garden drops away steeply. Can you still survey the rear roof?
Yes, and that is the exact problem the aircraft solves in Crumlin. We fly the rear elevation from open air, so the gradient behind the house is irrelevant. No ladder gets footed on a slope and no scaffold has to be built up from one.
Do you inspect industrial or heritage structures, not just houses?
Yes. Former works buildings, retaining walls, bridges and industrial units around Crumlin, Newbridge and Abercarn are regular work. Where monitoring is needed we can repeat identical flight positions on later visits so the images are genuinely comparable.
Can you find where a leak is getting in?
It is the most requested job here. We survey the full roof at high zoom to identify the actual breach rather than the ceiling stain, which is often several metres away. Insurers call this trace and access, and most policies contribute towards the cost.
How much disruption is there for neighbours?
Very little. No scaffold, no pavement licence and no vehicle blocking a narrow valley street for days. We are usually on site for under an hour, and the aircraft is considerably quieter than most people expect.
What area around Crumlin do you cover?
