Storm damage roof inspection in Dawlish

Dawlish sits in a narrow valley cut into red sandstone cliffs, split by the Dawlish Water, with the main railway line running along a sea wall at the foot of the town that has made national news more than once for the storms that damage it. That same wall sits directly beneath the Regency and Victorian terraces around The Lawn, so a south-easterly gale throwing sea water over it reaches the nearest buildings almost immediately.

Up on the cliff tops, an entirely different exposure exists: extensive post-war bungalow development takes unbroken wind with no valley shelter at all, a different storm experience to the sheltered feel of the valley floor a short walk away.

On the terraces around The Lawn and the seafront hotels and apartment blocks, rendered parapets and natural slate take the combined hit of wind and spray thrown up from the overtopped sea wall, with ridge and verge failures common after a bad blow. Salt reaches these buildings in a more concentrated dose than almost anywhere else on this stretch, because the wall itself is actively delivering it during a storm rather than the wind simply carrying it.

The cliff-top bungalows take a more straightforward wind-loading problem: flat felt roofs on extensions, and concrete interlocking tile on the main pitches, both under the kind of unbroken pressure a valley property never sees. Ridge, verge and flashing failures are common after a bad storm season here specifically because nothing on the cliff top slows the wind down first.

Dawlish Warren, at the mouth of the estuary a short way south, takes a related but distinct exposure to the cliff-top bungalow estates above the town centre, with lower, more open ground catching wind in a different way to the cliffs. The EX7 postcode covers both, and Exeter, close enough for a same-day booking, sees nothing like the storm force that reaches the Dawlish sea wall.

Because the same sea wall that carries the railway also runs beneath the town's oldest housing, a storm severe enough to close the line and make the national news is usually the same storm that has already damaged roofs along The Lawn, and the two get reported on very different timescales. Rail disruption is public within hours; a slipped ridge tile on a nearby terrace can go unmentioned for weeks unless someone has reason to look up.

A flown pass over both the valley floor terraces and the cliff-top estates in the same visit gets the full picture regardless of which part of town took the worse hit in a given storm, and ties the record to the specific event rather than to Dawlish's general reputation for rough winters, which is not something an insurer can date a claim against.
