When the Great Western Railway reached Chippenham in 1841, it brought employers and housing with it. Terraces built to house railway and engineering workers share roofs, walls and often chimneys, and that shape defines the repairs they need.
Q2.1Why does a neighbour's stack leak into my house?
On a terrace, each chimney stack often serves two houses, and the junction between roof and party wall is a long run of flashing. Where lead or mortar fillets have failed, water gets in at the wall and runs down inside it, showing up on the ceiling of a house that looks perfectly sound from the street. Rebuilding a stack that sits on a party wall, or taking out a chimney breast, brings Building Regulations approval into play, with a party wall notice where the wall is shared. Our chimney repairs page explains the process.
Q2.2What happens where a rear extension meets the main roof?
Rear extensions on terraces create valleys against the main roof, and these are the places where a small amount of debris becomes a large amount of damp. Back gutters behind chimneys collect leaves and moss, and they are easy to forget because nobody sees them from the ground.
Q2.3Will a patch show along a whole street?
On a street of near-identical roofs, a patch in the wrong tile can be seen from the pavement all the way along. We match tile size, colour and profile as closely as possible, using sound reclaimed material where it suits, so the repair reads as one roof. Where replacement is the better course, we talk through the choices before anything is priced. A long terrace run may be best done in a single stage, so the finished roof is consistent from end to end, rather than house by house over several years.
A neighbour's roof and yours are linked, so a friendly word before work starts saves awkward moments later. Scaffolding on a terrace often has to cross a neighbour's line, and asking beforehand is simply good manners, and good practice.
