Bampton has several houses of real age. Ham Court grew from a castle gatehouse and curtain wall, and the Deanery and Weald Manor are of similar standing. Roofs on buildings like these are not simply bigger versions of an ordinary house roof.
Q2.1Why understand the building first?
Before we price anything we look at what the roof is made of, how it has been altered, and which route the water has taken in. Old roofs carry the marks of past repairs, and reading them tells us what has already been tried. A patch in an unsuitable material shows where an earlier repair went astray; one in the correct material shows a job done properly. The survey photographs record all of it.
Q2.2Must the materials and methods match?
For a listed house we begin from the existing covering, fixed in the existing manner. Changing a covering, or altering a chimney, affects the building's special character and needs listed building consent from the local authority. If any part of the structure is also a scheduled monument, scheduled monument consent is a separate matter, decided by the Secretary of State. We raise these questions early, and we do not start until they are settled.
Q2.3Can the structure take a heavier covering?
Old frames carry old coverings, and they have often been carrying them for centuries. Replacing with something heavier, even a different stone or tile, changes the load, and the structure has to be checked. For a larger project on a building of this kind, our listed roof repairs page sets out how repairs are planned.
On a protected building the quickest fix is rarely the right one. The right one is the repair that keeps the original fabric and keeps the weather out.
