Drone inspection services in Tiverton

Tiverton's older industrial buildings are the ones with the interesting roofs: large-span mill and works structures, north light and sawtooth ranges, tall stacks, and coverings that have been patched across several eras. The modern estates east of the town are conventional portal frame and much easier to plan for, but the two sit within a mile or two of each other and a portfolio here often contains both.

A sawtooth or north light roof is a different inspection altogether. It has far more linear metres of gutter per square metre of roof than a duo-pitch shed, most of it internal, and every one of those valleys is a potential ingress point. The glazing runs are usually original or nearly so, and their condition is a real cost question rather than a cosmetic one.

From the air the whole run of valleys is visible at once, which is close to impossible to achieve safely on foot. On a roof of that construction it is also the difference between finding one blocked valley and understanding that six of them are silting at the same rate.

The Exe valley here is notably wet, well above the county average, and the town is built on steep-sided ground with the centre low and streets climbing sharply north and west. Two consequences follow for anyone maintaining a building.

First, sustained wetting. Anything that relies on drying out gets less opportunity to do it here than almost anywhere else in Mid Devon, so growth, silting and corrosion all run faster than the general expectation for an inland town.

Second, the steep sites mean many roofs sit above the general roofline, where wind loading is higher than the surrounding buildings would suggest. A unit part way up the hill can take gusting that a comparable unit on the valley floor never sees, and its perimeter fixings show it.

For the mill and works stock, an inspection focused on the valleys, the glazing and the stacks. For the estate stock, the standard pass over sheets, gutters, rooflights and plant. For a portfolio holding both, one visit and one report, with the two building types written up separately because their maintenance cycles have nothing in common.

Autumn is the right slot for either. It is the point where the previous winter's damage has had a full year to develop and where gutter work still has time to be booked before the next one.

The canal and the older transport infrastructure add a further class of structure that nobody obvious is responsible for inspecting: wharf buildings, bridges, workshops and stores associated with the Grand Western Canal, plus school and institutional estate around Blundell's and the town centre. These are buildings with long roofs, restricted access and often heritage constraints on any physical intervention, which puts them squarely in the category where an aerial record is the only survey anybody is realistically going to get.
