Roof leak detection in 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.
A medieval core with a motorway-corridor ring
Cullompton's centre along Fore Street is medieval and Georgian, cob and thatch in the older lanes behind the main frontages, while the town as a whole has taken on a very large volume of late twentieth century estate housing and continues to grow with new development close to the M5. Natural slate and thatch cover the old core, concrete interlocking tile the estates, and profiled metal sheet turns up on the industrial units near the motorway junction.
New-build roofs generally start life sound, so a leak on this newer stock is often a workmanship or detailing fault from the build itself rather than age-related wear, which is a different thing to look for than the slow decay a Fore Street thatch roof shows.
Tiverton, Exeter and Honiton are all close enough for a single trip, and Wellington lies just over the Somerset border for context, though each town covered here has its own separate page written around its actual roof stock rather than Cullompton's motorway-corridor growth pattern assumed to apply everywhere.
A valley floor town that holds its damp
Cullompton sits on flat ground in the Culm valley, with the Blackdown Hills to the east and rolling Mid Devon farmland to the west, and that valley floor location means the town holds damp and frost more than the higher ground around it, so both thatch and shaded slate stay wet for longer here than they would on a hillside a few miles away.
On the newer estates, the more common fault is at the junction between two roof planes or where a dry ridge system was not bedded correctly at the build stage, a detail that a thermal pass can pick out cleanly on a uniform modern covering.
The EX15 postcode area has grown fast alongside the motorway corridor, and a trace booked for one of the newer estate addresses out there is, in practice, usually a quicker job than one in the historic lanes off Fore Street simply because the roof is younger and less complicated.
Old thatch and new estates need different flights
A thatch roof on Fore Street calls for the same careful, non-invasive approach as anywhere else this material appears: establishing roughly where the damp sits before anyone considers opening the coat up.
The estate ring nearer the motorway is a faster job in practice, straightforward access, uniform roofs, and often a newer-build defect the report can point a housebuilder's aftercare team at directly rather than leaving the owner to argue the case alone.
The Walronds and the other older buildings just off Fore Street carry real historic thatch and slate roofs that deserve the same careful, non-invasive approach as anywhere else this material appears in this site's coverage. Whether the job is a listed cottage or a new estate house near the motorway junction, the price is fixed before the visit and the written report lands within 48 hours either way.
Behind the trace
What Cullompton clients are actually buying
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.
