1. Get Quote
Submit the form. We calculate the exact travel rate from our NP4 HQ (approx £20-£35 depending on BS postcode).
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 quiet, high-stability drones to scan delicate Bath stone and complex rooflines. Ideal for Clifton's terraces or Hotwells' waterside villas.
4. Receive Data Package
You receive a PDF Condition Report and a link to every raw image & 4K video to show your insurer, conservation officer, or roofer.
The "Conservation First" Guarantee
We understand the sensitivity of listed buildings and conservation areas. If we arrive and cannot fly due to sudden weather or unexpected airspace restrictions near protected sites, you do not pay a penny.
*Disclaimer: Rescheduled visits are billed at the original quoted rate.
Scaffold-Free Heritage Audits.
Why risk damage to Grade-listed facades when you can inspect from the air?
Installing scaffolding around Georgian properties in Clifton can be costly, time-consuming, and potentially damaging to the historic fabric.
Our drone survey provides a respectful, efficient alternative:
- ✅ Evidence for Insurance: Validation for storm damage claims with 4K photos.
- ✅ Conservation Compliance: Non-invasive inspection reports for heritage authorities.
- ✅ High Level Access: Inspect complex rooflines and rear elevations safely.
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 (£600+ in Bristol).
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 in BS8?
"The survey flagged a potential roof issue."
Banks often demand a "Specialist Roof Report" before releasing funds on older Clifton properties. 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 for your claim.
- ✅ Independent Validation: We don't profit from the repair.
Typical Defects We Expose
Damaged / Slipped Tiles
Identify slipped or missing slates causing water ingress. Critical for Trace and Access on complex heritage rooflines.
Chimney Stack Pointing
Check for cracked pointing, damaged pots, and lead flashing issues. Crucial for storm damage assessment on exposed properties.
Blocked Guttering Check
Spot blockages, vegetation growth, and sagging brackets in complex valley gutters.
Fascia / Soffit Issues
Identify water damage and rot on wooden fascia boards.
BS8 Housing Intelligence
Our drones are calibrated to spot specific defects common to the Clifton/BS8 area:
- Listed Building Sensitivity: Identifying freeze-thaw damage on delicate Bath stone.
- Georgian Valley Gutters: Inspecting complex "M-profile" valleys common in crescents for blockages.
- Avon Gorge Exposure: Checking for salt-air masonry degradation on waterside properties in Hotwells.
- Steep Incline Access: Inspecting rear elevations of hillside properties where ladders cannot reach.
