The "Hillside" Guarantee
Valleys weather can change fast. If we drive over the mountain and cannot fly due to sudden rain or wind, you do not pay a penny.
*Disclaimer: This guarantee provides zero upfront risk for you. Rescheduled visits are billed at the original quoted rate.
Don't Block The Street.
Scaffolding in the Valleys is a headache.
On narrow terraced streets in Blackwood or Pontypridd, putting up scaffolding often means getting a council permit to block the pavement or road.
Our drone survey solves this instantly:
- ✅ No Permits Needed: We fly from your property boundary.
- ✅ No Angry Neighbours: We don't block parking spaces with skips or vans.
- ✅ Steep Roof Access: We can inspect the rear of hillside properties easily, where ladders can't reach.
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. Whether your roof is perfect or falling apart, our price is the same.
2. The Evidence
The Roofer: "Trust me, mate." (Verbal opinion or a blurry phone photo).
CalonTerra: A downloadable Visual Condition Report with zoomed-in 4K photos of every crack, slip, and seal.
3. The Cost
The Roofer: You pay for scaffolding just to *look* at the problem (£500+).
CalonTerra: You pay a small fee for the truth. You only pay a tradesman to fix the specific damage you can actually see.
Buying or Selling?
"The Mortgage Lender has put a retention on the house."
Buying an older terrace in the Valleys? Lenders often demand a "Specialist Roof Report" due to the age of the slate. Standard RICS Homebuyer surveys often state "Roof not inspected - obscured from ground."
The Solution: We provide the independent, 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: Irrefutable 4K photos of fresh tile breaks.
- ✅ Date-Stamped Data: Proof of when the damage occurred.
- ✅ Independent Validation: We don't profit from the repair.
