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.
Don't Ask a Roofer if You Need a New Roof
We are Independent Data Collectors. We don't fix roofs, so we have no incentive to "find" extra work.
1. The Incentive
The Roofer: Makes money by finding defects, selling materials, and increasing the job scope.
CalonTerra: We charge a fixed flat fee. Our price is the same whether your roof is perfect or needs repair.
2. The Evidence
The Roofer: Often relies on verbal opinions or blurry ground photos.
CalonTerra: A downloadable Visual Condition Report with zoomed-in 4K evidence.
3. The Cost
The Roofer: You may pay for scaffolding just for an estimate.
CalonTerra: A small fee for the truth. Only pay a tradesman to fix the specific damage you can see.
Buying or Selling in CF83?
"The Mortgage Lender has put a retention on the house."
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 new and not just "wear and tear."
- ✅ HD Evidence: 4K photos of fresh damage.
- ✅ Date-Stamped Data: Proof for your claim.
- ✅ Independent Validation: Unbiased reports.
