Roof leak detection in Sidmouth

Sidmouth's Regency and early Victorian core is unusually intact, and the roofs match the elevations: rendered and painted fronts hiding complicated rooflines behind them, ornate ironwork, and roof planes that turn corners and step down in ways a plainer Georgian town rarely attempts. Slate and clay plain tile dominate, with thatch in the outlying villages and lead-lined valleys and parapet gutters doing the quiet, unglamorous work of keeping the whole arrangement dry.

Later villas climb the valley sides above the esplanade, and post-war housing at Sidford and Sidbury sits further out on plainer roofs, but it is the Regency core's hidden lead detail that gives this town its particular leak problem: a lot of water is managed out of sight, behind a parapet, rather than shed openly off a simple slope.

Budleigh Salterton, Ottery St Mary, Honiton and Seaton are all within reach for the same visit, and each of those towns gets a page written around its own dominant roof era rather than Sidmouth's Regency parapet detail assumed to apply everywhere nearby.

The Sid valley funnels wind straight off the sea and up through the town, with Peak Hill and Salcombe Hill either side pushing it into gusting, turbulent patterns around ridges and chimneys rather than a steady prevailing direction. Salt reaches the esplanade properties hard, and that same turbulence is what works flashings and lead dressings loose over time on buildings a calmer valley would treat more gently.

A parapet gutter that has silted or a lead valley that has moved fractionally under thermal expansion fails inward, filling behind the parapet and overflowing into the building rather than dripping visibly off an eave, which is exactly the kind of fault a stain on a top-floor ceiling gives almost no clue about from inside.

The EX10 postcode area takes in Sidford and Sidbury as well as the Regency core, and a trace booked for either of the outlying villages gets the same fixed price and the same written report as one booked on the esplanade itself.

A visual pass over a Regency parapet shows very little, because the whole point of the detail is that it is out of sight. A thermal pass over the same run of gutter, taken while a recent wet patch is still losing heat differently to the dry lead around it, gives evidence a ground-level inspection cannot.

The steep hillsides either side of the town also make scaffold access to some of these upper roofs a properly awkward, expensive job, which is a second, entirely separate reason to establish where the water is entering before committing to it.

The Jurassic Coast cliffs either side of town are a geological reminder that this stretch of coast has always been shaped by the same forces now working on its roofs, wind, salt and driving rain finding every weakness over time. A trace here is priced and booked the same way as anywhere else on this site, a fixed figure agreed before the visit and a written report inside 48 hours, regardless of how elaborate the roofline turns out to be.
