The short answer
Each material has its own faults and its own remedy. Tiles and slate depend on sound battens, fixings and flashings, and lead around chimneys and dormers wears first. A thatched neighbour does not stop work on the rest of a house, but it shapes how access is planned.
A parish with several coverings is one where no single method suits every house. Before a job is priced the questions are simple: what is the roof made of, how is it held on and what has actually failed. Once we have surveyed, you receive a written total price with pictures of your roof; if you hold other quotes, check whether they include VAT and scaffolding.
Q3.1What goes wrong on a clay-tiled roof?
Plain clay tiles hang from battens on small nibs, with nails in only some courses. Over time battens soften, nails corrode, frost cracks tiles and a mat of moss keeps the surface wet. A few slipped tiles are a quick fix. A whole slope that has lost its fixings needs stripping, new battens and underlay, and the sound tiles laid again with new ones matched in. Condition decides, not age.
Q3.2Where does lead give way first?
At the details: around chimneys, along abutments, in valleys and on any dormer cheek. Lead lasts a long time when correctly installed, yet it fatigues where it has been stretched, and old stuck-on repairs make things worse. A soaker is a folded lead tab slipped beneath each course beside a wall or chimney, with the flashing covering the join above it. Renewing both in the right lead code is usually a modest job.
Q3.3Why do tiles lift on exposed ground?
Wind pulls at the verge, the ridge and the edges, and where fixings are missing the tiles move. Checking those edges takes minutes during a survey, and refixing them costs far less than repairing the storm damage that follows when they go. For the process in more detail, see our roof repairs page.
