The short answer
Old timber frames, in most cases adapted many times. Around the Cloth Hall and its half-timbered granary, a roof is often only as sound as the frame beneath it, so checking timbers, joints and earlier repairs matters as much as replacing a missing tile.
A medieval market town leaves its mark in the roofs. The Cloth Hall and granary are rare survivors, and the buildings around them, even where later, tend to share the same habits: irregular timbers, uneven lines and a history of alteration. Anyone repairing them is working with that history, not against it.
Q1.1Why do old timber-framed roofs leak in odd places?
Water follows the structure. A frame that has twisted a little over generations opens gaps where roof meets wall, and rain that gets in can run along a beam a long way before showing up as a stain somewhere surprising. We therefore trace a leak from the inside as well, looking along rafters and wall plates, before deciding where to repair. The loft, where there is access, tells us more than the outside alone.
Q1.2Can a new covering be laid on an old frame?
Sometimes, but weight and fixing both matter. A new covering far heavier than the old one loads timbers never meant to carry it, and Approved Document A treats anything more than 15 per cent heavier as a point to check. Where a frame is tired, we may recommend strengthening or replacing particular timbers rather than a full new roof. That is a smaller and kinder job, and the survey photographs show exactly which timbers we mean.
Q1.3What happens around the church?
Take St Nicolas: while Anglican services continue, the ecclesiastical exemption covers the building, and any change is settled through a faculty rather than listed building consent. Houses and shops near the church do not share that exemption, and the work on them follows the ordinary rules, which is why a survey comes before any promise about consent. For those, roof repairs that keep to the existing materials and method are usually the simplest route.
Wherever we work in the centre, we keep the site tidy and take the waste away when the job is done. Narrow streets and busy pavements mean we plan deliveries and scaffold positions with the neighbours in mind, so that shopfronts and doorways stay clear.
