The short answer
Slowly and in matching material. Cottage roofs here have commonly been reworked more than once, so each slope is mapped first, then repair with tiles or slates of the same size, colour and laying pattern, and only strip a slope when re-fixing cannot cure the fault.
A cottage roof is a record of the house's history. Chimneys have been rebuilt, dormers added or removed, and the covering renewed one slope at a time. Reading that record is the first stage of any repair.
Q1.1Why map the cottage roof first?
We walk the roof, photograph each slope and note which areas are original and which are later. Original coverings often hold years of life if they are well fixed, and re-fixing them is usually the cheaper and kinder route for the building. Patches from earlier repairs are the usual source of trouble: the wrong size of tile, a cement fillet that has cracked away, or a flashing dressed too stiffly. Before anything is touched, the leak itself is traced to its entry point, a process set out on our roof repairs page.
Q1.2How is a new slope matched to the old?
If one slope has to be re-covered, the new work needs to sit comfortably beside the old. That means choosing tiles by size, thickness, texture and colour, then laying them at the gauge the existing roof uses. Reclaimed tiles can help, though they must come from a source that does not strip another building of its own roof, and they should be sorted for cracks before they go back up. A visit to a salvage yard with the old tile in hand beats ordering from a picture.
Q1.3Does Aston's conservation area matter?
Aston's conservation area dates from 1998. West Oxfordshire District Council publishes a map for it, and we advise checking that map and, if your house is listed, asking the council before you commit. Like-for-like repair work rarely needs consent, whereas a change to the roof's visible form or material can.
At handover the garden is left tidy and the rubbish goes with us, and you keep the photographs of what we found, which gives the next owner a record too.
