# Roof Leak Detection > Thermal and visual drone tracing finds where a leak is entering a roof before anyone strips it, with a dated report your builder or agent can use straight away. Someone with an active leak they cannot trace, and the builder, roofer or agent they have already called who cannot find it from the ground either. A visual pass and a radiometric thermal pass over the same roof, flown together, so the wet patch under the covering shows up before a single tile comes off to go looking for it. ## Services - [Leak Trace](https://roof-leak-detection.co.uk/services/leak-trace): A visual pass and a radiometric thermal pass over the same roof, compared, so the entry point can be narrowed down before anyone strips a covering to go looking for it. - [For Builders and Agents](https://roof-leak-detection.co.uk/services/for-builders-and-agents): A dated thermal and visual leak trace your client can book directly, with the report addressed to you, so you are working from evidence rather than a phone call and a guess. ## Key pages -

[Exeter, Devon](https://roof-leak-detection.co.uk/areas/exeter): Leak tracing across Exeter, from lead-lined Georgian parapets in Southernhay to concrete tiled 1970s estates at Whipton, thermal and visual flown together. - [Topsham, Devon](https://roof-leak-detection.co.uk/areas/topsham): Leak tracing in Topsham, where lead valleys and box gutters hidden behind Dutch gables make a thermal pass worth far more than a look from the Strand. - [Exmouth, Devon](https://roof-leak-detection.co.uk/areas/exmouth): Leak tracing in Exmouth, across Regency villas on the hillside, inter-war suburbs at Withycombe Raleigh and flat-roofed seafront blocks that take the South West's hardest salt exposure. - [Budleigh Salterton, Devon](https://roof-leak-detection.co.uk/areas/budleigh-salterton): Leak tracing in Budleigh Salterton, where long-held Victorian and Edwardian villas on generous plots have often gone decades between anyone actually looking at the roof. - [Sidmouth, Devon](https://roof-leak-detection.co.uk/areas/sidmouth): Leak tracing in Sidmouth, where an unusually complete Regency roofscape of lead-lined valleys and parapet gutters sits in a wind-funnelling valley that punishes every weak joint. - [Ottery St Mary, Devon](https://roof-leak-detection.co.uk/areas/ottery-st-mary): Leak tracing in Ottery St Mary, from cob and thatch survivals in the lanes to the concrete tiled estates spreading north, where a damp valley floor keeps every roof wetter for longer. - [Honiton, Devon](https://roof-leak-detection.co.uk/areas/honiton): Leak tracing in Honiton, along a rebuilt Georgian high street prone to sitting fog, where a damp roof and an actively leaking one can look identical from the ground. - [Seaton, Devon](https://roof-leak-detection.co.uk/areas/seaton): Leak tracing in Seaton, where post-war bungalows behind the front carry flat felt extensions that shed wind-driven rain far worse than the pitched roofs above them. - [Axminster, Devon](https://roof-leak-detection.co.uk/areas/axminster): Leak tracing in Axminster, on a hilltop market town where wind from every quarter works ridge and verge details on Georgian, Victorian and former industrial roofs alike. - [Cullompton, Devon](https://roof-leak-detection.co.uk/areas/cullompton): Leak tracing in Cullompton, where cob and thatch along Fore Street sit beside a fast-growing ring of new estates on the M5 corridor, each needing a different read. - [Tiverton, Devon](https://roof-leak-detection.co.uk/areas/tiverton): Leak tracing in Tiverton, on steep streets above the Exe where Victorian mill terraces and post-war estates both sit higher above the general roofline than most towns allow. - [Crediton, Devon](https://roof-leak-detection.co.uk/areas/crediton): Leak tracing in Crediton, where cob and thatch cottages and Devon slate on the high street sit in a red sandstone valley that traps damp against both. - [Okehampton, Devon](https://roof-leak-detection.co.uk/areas/okehampton): Leak tracing in Okehampton, at the wettest, windiest edge of Dartmoor, where granite-bedded ridges and post-war estates stay wet longer than almost anywhere else this site covers. - [Tavistock, Devon](https://roof-leak-detection.co.uk/areas/tavistock): Leak tracing in Tavistock, where a Victorian mining-wealth town of Hurdwick stone and tall stacks sits on Dartmoor's edge, taking rain up the Tamar valley from the south west. - [Plymouth, Devon](https://roof-leak-detection.co.uk/areas/plymouth): Leak tracing across Plymouth, from asphalt flat roofs on the rebuilt post-war centre to Victorian terraces on the Hoe, where salt-laden Channel wind reaches well inland across the city. - [Saltash, Cornwall](https://roof-leak-detection.co.uk/areas/saltash): Leak tracing in Saltash, on near-vertical waterfront streets under the two Tamar bridges, where slate-hung villas and flat garage roofs both take the estuary's salt-laden wind hard. - [Newton Abbot, Devon](https://roof-leak-detection.co.uk/areas/newton-abbot): Leak tracing in Newton Abbot, across the railway-era Victorian terraces of a low, misty floodplain town where shaded slate holds moss longer than almost anywhere inland. - [Teignmouth, Devon](https://roof-leak-detection.co.uk/areas/teignmouth): Leak tracing in Teignmouth, the one Devon town this site covers that takes its worst weather from the east, catching seafront details designed only for the south west. - [Dawlish, Devon](https://roof-leak-detection.co.uk/areas/dawlish): Leak tracing in Dawlish, on a storm-battered stretch of coast where cliff-top bungalow estates and a Regency terrace both take unbroken south-easterly gales after every storm season. - [Torquay, Devon](https://roof-leak-detection.co.uk/areas/torquay): Leak tracing in Torquay, across grand Victorian hotel roofscapes with lead-lined parapet gutters, hard to reach and hard to see from the ground even before a leak starts. - [Paignton, Devon](https://roof-leak-detection.co.uk/areas/paignton): Leak tracing in Paignton, across a flat, open stretch of Tor Bay where inter-war seaside semis and guest house flat roofs both meet easterly weather with no shelter at all. - [Ivybridge, Devon](https://roof-leak-detection.co.uk/areas/ivybridge): Leak tracing in Ivybridge, an overwhelmingly late twentieth century commuter town on Dartmoor's southern edge, where moor-driven wind tests ridge and verge fixings estate after estate. - [Barnstaple, Devon](https://roof-leak-detection.co.uk/areas/barnstaple): Leak tracing in Barnstaple, North Devon's main town at the tidal limit of the Taw, where Atlantic rain reaches almost unbroken and prolonged wetting is the main cause of decay. - [Taunton, Somerset](https://roof-leak-detection.co.uk/areas/taunton): Leak tracing in Taunton, Somerset's county town, ringed by hills and drier than Devon on average, where localised gusting off the surrounding escarpments still catches roofs unprepared. - [Weymouth, Dorset](https://roof-leak-detection.co.uk/areas/weymouth): Leak tracing in Weymouth, behind the unbroken Georgian esplanade where hidden parapet gutters fail by filling and overflowing inward, never showing a drop outside until the ceiling has. ## What is on the record - CAA registered: Operator ID and Flyer ID held, plus the A2 Certificate of Competency. Every trace is planned to the rules that apply to the site, and the paperwork is available before the visit if your agent, insurer or a managing agent wants it. - Radiometric thermal: A DJI Mavic 2 Enterprise Advanced carrying a 640 by 512 thermal camera. Water and the material around it hold and release heat differently to a dry roof, which is how a leak gets traced back towards its entry point rather than guessed at from a ceiling stain. - 100 megapixel camera: A DJI Mavic 4 Pro with a Hasselblad camera and 6K video, flown alongside the thermal pass. The resolution means a candidate entry point can be shown close up, from a safe standoff distance, without the image falling apart when your roofer zooms in. - Insured with Coverdrone: Full commercial cover for the operation. Certificates go to letting agents, managing agents and insurers as a matter of course, without anyone having to chase for them. ## Contact - Phone: 07476 926544 - Email: info@exeterdronesurveys.co.uk - Enquiry form: https://roof-leak-detection.co.uk/contact - Based in Exeter, covering Devon and the South West ## Optional - [Full text version](https://roof-leak-detection.co.uk/llms-full.txt): every service, town and question on this site as markdown. - [Sitemap](https://roof-leak-detection.co.uk/sitemap.xml) - [Privacy](https://roof-leak-detection.co.uk/privacy) - [Terms](https://roof-leak-detection.co.uk/terms)
