Roof leak detection in Okehampton

Okehampton's town centre is built from granite and slate, with Victorian terraces behind it, a large stock of post-war housing, and scattered moorland farms and longhouses in the surrounding parishes. Natural slate with granite-bedded ridges is the traditional covering, alongside corrugated metal on farm buildings and concrete tile on the more recent estates.

A granite-bedded ridge is a heavier, more robust detail than a mortar-bedded one, but it is not immune to the exposure this particular town gets, and once a bedding joint has opened here the same wind-driven rain that makes the exposure notable in the first place finds its way in fast.

Tavistock, Crediton and Holsworthy are all close enough to combine into one visit, and each has a separate page here, because the exposure Okehampton gets sitting directly under Dartmoor is plainly different from a sheltered market town a few miles further from the high ground.

Okehampton sits at the northern foot of Dartmoor where the East and West Okement meet, with the high moor and Yes Tor rising immediately to the south, and that position forces Atlantic air upward right on the town's doorstep. Rainfall is high, driving rain is frequent, and roofs here stay wet for unusually long periods compared with almost any other town this site covers.

That persistent wet is a double-edged fact for a leak trace: it means a fault, once present, is under sustained pressure and likely to be doing real damage, but it also means the ground truth, the imagery, has more contrast to work with than a drier town would offer, provided the flight is booked with the forecast rather than against it.

The EX20 postcode area runs right up to the moor edge, and a trace booked for a property closer to Dartmoor than the town centre should expect a noticeably wetter, windier flight than the same booking made a few miles further from the high ground.

The scattered farms and longhouses in the parishes around the town are exactly the kind of site where getting a tower up is a properly major undertaking, long tracks, awkward access, and often more roof than a single day's scaffold hire is built around.

Okehampton Castle and the wider Dartmoor National Park sit right at the edge of town as a reminder that this is a place built at the meeting point of moor and valley, and a trace flown here is planned around that exposure rather than treated as routine.

Meldon Viaduct out towards the moor is a reminder of just how much engineering this landscape has always demanded to manage water and wind, the same forces a domestic roof here deals with on a much smaller scale. A trace booked in Okehampton is planned around the forecast as much as the diary, and the report says plainly what the day's conditions did and did not allow the thermal pass to confirm.
