The paper mill and large-scale roofs
Industrial buildings put area, access and drainage ahead of ornament.
The former paper mill dates from around 1860 and is Grade II listed, with a water wheel still driven by a small canal from the river. The mill was built for industry, and its roofs were meant to cover space cheaply and drain it quickly. A building of this sort has broad pitches, long runs of gutter and, often, large areas of glazed or lit roof that were designed to bring daylight to the work floor.
The problems on that scale are of a different order from those on a cottage. A long gutter that falls slightly the wrong way ponds, and a ponded gutter fails. Brackets that carried the original iron or timber gutters can rust or rot. An outlet that blocks in autumn leaves overflows the full length of a wall. A lost fixing in a large sheet or tile run can spread to its neighbours in the first strong wind.
We survey a building like this in sections, often from a mobile platform or scaffold, and we write the findings up by roof plane so that an owner or managing agent can see where the risk lies and what can wait. The report separates urgent items from planned ones and places a figure on each part once we have measured it.
Where a historic industrial building has been converted to housing or offices, as many mills have, the roof often serves several occupiers. We then work with the managing agent on a single scope that all parties can see. Pricing is set after the survey; a large complex building gets a survey scope agreed in advance, as the national cost guides only cover simple cases. Larger and non-domestic work is covered under commercial roofing.
The listing means any significant change to the roof needs consent from Somerset Council before it begins: matching repairs prompt a conversation, while altering covering, rooflights or outlets means making a formal request.
Large roofs
On a mill-scale roof, survey first by section, then repair what is failing and plan the rest.
