Aerial thermal drone view of residential roof showing heat loss and water ingress

CAA Licensed · £10M Insured · Same-Day Report

Roof & Chimney Inspection Your Roof Has Secrets.
We Find Them.

The UK's only aerial inspection that sees water ingress before it reaches your ceiling. From a quick visual check to a full radiometric thermal survey — evidence-quality results, delivered the same day.

✓ From £199 ✓ No ladders or scaffolding ✓ Report within 24hrs ✓ Insurance-ready documentation

Why It Matters

Most roof damage is invisible
until it's expensive

Water ingress, failing flashing, cracked pointing and heat loss rarely announce themselves. By the time you see a damp patch on your ceiling, the damage has often been spreading for months. An aerial inspection catches problems before they escalate.

DJI Matrice 4T Northampton — thermal roof inspection drone — Skyline Drone Services

DJI MATRICE 4T · RADIOMETRIC THERMAL

Professional Equipment

Why the kit
changes everything

Consumer drones take photos. The DJI Matrice 4T captures radiometric data. Every pixel in a thermal image contains a precise, calibrated temperature reading — not just a colour. That's the difference between seeing a warm patch and knowing it's 4.7°C above ambient, confirming active moisture.

We post-process every thermal image using DJI's Thermal Analysis Tool, applying emissivity correction and isothermal analysis to produce findings that hold up to scrutiny from contractors, loss adjusters and insurers.

Complete Reference

What each inspection
finds & misses

Visual inspection reveals surface defects. Thermal reveals what's happening beneath and inside. Together they give a complete picture — but only thermal finds the problems that cause the most damage.

Visual Inspection

Surface & structural defects

Roofing & Tiles

Cracked, broken or missing clay/concrete tiles

Curled, torn or missing asphalt shingles

Mechanical punctures in flat roof membranes

Granule loss on shingles

Chimneys & Masonry

Crumbling mortar joints (failed pointing)

Spalling bricks (surface flaking)

Cracked chimney crowns (flaunching)

Damaged or missing chimney pots/cowls

Drainage & Flashing

Gutter blockages (leaves, debris, silt)

Sagging or detached gutter brackets

Lifting or rusted lead/metal flashing

Vegetation growth in valleys or gutters

Cannot detect sub-surface moisture, heat loss or hidden structural faults

Thermal + Visual

Hidden & sub-surface defects

Everything in Visual, plus:

Sub-Surface Moisture — wet insulation retains heat longer than dry. Moisture hot spots become visible under the membrane following sunset

Thermal Bridging — missing or compressed insulation where heat is escaping through the building envelope, invisible to any camera

Air Leakage — warm air escaping from gaps around skylights, vents or the base of chimney stacks — detected as heat plumes

Chimney Safety — abnormal heat signatures through the masonry indicating a cracked flue liner or creosote fire risk

Finds the problems that cause the most damage — before any symptoms appear inside

Common Questions

FAQ

No — you don't need to be present. We fly from public land adjacent to your property where possible. If access to your garden is needed for flight positioning, we'll confirm that in advance. Most inspections are completed without the homeowner needing to be there.

A standard thermal camera shows a colour image representing temperature variation — useful, but not measurable. A radiometric camera stores the actual temperature value in every single pixel of the image. This means we can apply post-processing tools, isothermal analysis and emissivity corrections to produce findings that are scientifically defensible — the kind that hold up in insurance claims and contractor briefings.

Thermal inspections are most effective in cooler conditions — early morning or evening, or during autumn and winter. The temperature differential between wet/damaged areas and dry surfaces is larger in cooler ambient temperatures, making findings clearer. We'll advise you on the optimal conditions when you book and schedule accordingly.

Yes. Our reports are specifically structured for use by insurers and loss adjusters. They include radiometric data, calibrated temperature readings, defect severity ratings, drone flight metadata, our CAA licence reference and £10M public liability insurance certificate. We've had reports accepted by major insurers as primary evidence for claims.

We're based in Northamptonshire and cover the surrounding region including Bedfordshire, Buckinghamshire, Leicestershire, Oxfordshire and Warwickshire. Travel is included within Zone 1 (NN, MK, LU, SG, AL postcodes). A small travel supplement applies for Zone 2 locations — our instant quote calculator calculates this automatically from your postcode.

We monitor conditions closely and will contact you to reschedule if weather prevents a safe and effective flight. Our weather refund guarantee means you're never charged if we can't complete the inspection due to conditions outside our control. You'll receive a full refund or a rescheduled date — your choice.
