An old stone house in Shrivenham is a different proposition from a 1990s estate home. The walls are thick, the roof is steep, the timbers may be oak, and nothing is quite square. Re-roofing one means working with the building as it is.
Q2.1What happens before a Shrivenham re-roof is priced?
Before any quote, we look at the roof from outside, from the loft and, where needed, from scaffolding. We note the pitch, the covering, the condition of rafters, battens and underlay, and any earlier repairs. Each slope gets its own photographs. If only one slope is worn on an otherwise healthy roof, the quote covers that slope alone, since a whole new roof is not always the answer.
Q2.2How do you make a repair match the old roof?
A repair should look as though it was always part of the roof. For stone, that means stones of matching size and thickness, graded so the biggest sit low down and the smallest near the top. For clay tile or slate it means matching colour, size and texture. Our page on Cotswold stone roofing describes the traditional method, and the same principles apply to stone in this part of the Vale.
Q2.3Can the timbers take a different covering?
Stone is heavy. A traditional stone roof may weigh about 1000 kg per 10 square metres, according to Cotswold District Council's 2000 guidance, so the timbers have to be sound before anything is laid. Replacing stone with a different covering changes the load. The Planning Portal says a covering that is 15 per cent or more heavier needs building control approval, and Approved Document A treats an increase of more than 15 per cent as significant. We check what the structure can carry before we recommend a covering.
None of this has to be rushed. A roof that is surveyed in dry weather and planned for a settled spell is easier to do well. Stripping only as much as can be made weathertight by the end of each day is standard care on an occupied house, and it keeps a stone or slate roof from being left open to a sudden shower. The ridge and the hips are usually the last parts to be finished, once the slopes either side are complete. Old battens, broken stone and offcuts leave in our skip, not yours.
