Why pay for access when you can pay for data?
Hiring scaffolding for terraced properties in Bedwas or Trethomas can be logistically difficult and expensive.
Our drone survey provides a faster, more practical alternative:
- ✅ Evidence for Insurance: Validation for storm damage claims with 4K photos.
- ✅ Industrial Audits: Efficient scanning of large commercial roofs on the estate.
- ✅ Trace and Access: Find the exact entry point of a leak in minutes.
Bedwas & Trethomas: A Valley Floor Microclimate
What sitting in Machen Mountain's shadow does to a Rhymney Valley roof.
Shade, Moss and Slate Displacement
Bedwas and Trethomas sit low with high ground on either side, so north-facing pitches see very little direct sun. Moss and lichen hold moisture against the slate, freeze-thaw lifts the tail, and the tile walks out of its lap. It happens slowly and unevenly across a roof, and from the street you cannot tell a mossy roof from a moving one.
Colliery-Era Terraces, Shared Ranks
The terraced ranks built for Bedwas Navigation Colliery share ridges, valleys and party parapets. A defect above next door's bedroom regularly wets your ceiling, and neither household can see it. Photographing the full rank from above settles where the breach actually is before the conversation becomes expensive.
Bedwas Industrial Estate Sheeting
The estate's large-span units run long valley gutters that fill with leaf litter off the valley sides. Once a gutter backs up, water goes into the building rather than over the edge. We survey those runs and the rooflights without anyone stepping onto profiled sheeting, which is where most industrial roof injuries happen.
No Repair Quote Attached
We are surveyors, not roofers, so there is no follow-on job for us in whatever your Bedwas roof turns out to need. You pay a fixed fee, you receive every image and the 4K footage, and you take it to whichever trade you choose — or to nobody at all, if the answer is that the roof is sound.
Buying or Selling in CF83?
"The survey flagged a potential roof issue."
Banks often demand a "Specialist Roof Report" before releasing funds on period properties. Standard surveys often can't see high, complex roofs properly.
The Solution: We provide the high-level evidence your lender requires to lift the retention.
Insurance Claims & Storm Damage
If you are claiming for "Storm Event" damage, your insurer will demand proof that the damage is recent.
- ✅ HD Evidence: 4K photos of fresh damage.
- ✅ Date-Stamped Data: Proof for your claim.
- ✅ Independent Validation: Unbiased reports.

Bedwas Drone Surveys: CF83 Questions
What Bedwas, Trethomas and Machen residents ask us.
Can you tell whether moss is actually damaging my roof?
It is a genuinely useful thing to fly for in Bedwas. From above we can establish whether the moss is simply sitting on sound slate or whether it has lifted tails and opened the laps. The photographs let a roofer price the correct job rather than defaulting to a full strip and re-cover.
My neighbour and I share a roof. Can one survey cover both?
Yes, and on the Trethomas and Bedwas ranks we would encourage it. A single flight documents the whole shared roof plane and both households receive the same evidence, which tends to shorten the argument about which side the water is entering.
Do you inspect commercial units on Bedwas Industrial Estate?
Yes. Valley gutter surveys, rooflight condition and sheeting corrosion on large-span units are routine work for us, and they are considerably safer flown than walked. Imagery can be supplied in a format your insurer or maintenance contractor will accept.
How long does the drone need to be in the air over my house?
Around fifteen to twenty minutes for a standard property. Bedwas streets are tight, so we normally launch from the pavement or a front garden, hold the aircraft high and quiet, and are packed away inside the hour.
Is Bedwas inside your zero-travel area?
It is close to it. Travel from our Pontypool base is worked out for your exact postcode in the quote form on this page, so you see the complete figure — survey plus any travel — before deciding.
