Roof leak detection in 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.
A steep waterfront quarter into Cornwall
Saltash's old waterfront quarter is a notably steep run of terraced cottages on near-vertical streets, with Victorian villas above it, extensive post-war estates at Burraton and Latchbrook, and modern development along the Callington road. Natural slate and slate hanging on exposed elevations dominate the older stock, with concrete interlocking tile on the estates and flat roofs on the many garages and extensions that have been added over the years.
Slate hanging, tiles fixed vertically to a wall rather than a roof slope, exists here specifically because it works: it is a defence against exactly the driving rain this crossing point gets, and where it fails the water tends to enter behind the hanging rather than through it, invisible until it has already tracked some distance.
Plymouth, Liskeard and Tavistock are all within reach of the same trip across the Tamar, and each has its own page here, written around its own building stock, since the estuary wind that shapes Saltash's slate hanging does not reach every one of those towns the same way.
A funnel of wind under two bridges
The Tamar funnels wind hard up and down the valley at the crossing point, and Saltash takes salt-laden air off the estuary as a matter of course rather than only in storms, conditions that work on flashings, hanging tiles and flat roof upstands harder than a more sheltered town a few miles inland would experience.
On the flat roofs over garages and rear extensions, so common across the post-war and modern parts of the town, the upstand where the covering meets a wall is the recurring weak point, exactly the kind of localised fault a thermal pass isolates cleanly against the dry roof field around it.
The PL12 postcode area sits just over the Tamar from Plymouth, and although the crossing is short, the weather and the building stock on this side of the bridge are plainly different, older, steeper, and more exposed to the funnelled estuary wind.
A gradient that makes access properly expensive
The drop from the town centre to the waterfront beneath the two bridges is steep enough that conventional scaffold access on the older streets is a specialist, costly undertaking before any work has even started, which is exactly the situation a flown trace, needing only a clear launch point rather than a route a lorry can climb, is built for.
For the newer estates further from the water the job is more straightforward, regular plots and easier access, but the same estuary wind still reaches them, so the exposure does not stop simply because the gradient does.
Saltash Passage, the older crossing point downstream of the two bridges, sits alongside some of the town's oldest slate-hung cottages, and access down to that stretch is exactly the kind of steep, narrow route a scaffold lorry struggles with. A trace needs only a lawful launch point, and the fixed price is agreed before the visit regardless of how awkward the street itself turns out to be.
Behind the trace
What Saltash 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.
