Chimney repairs and rebuilds
A leaning or spalling (crumbling brick) chimney is a structural safety issue, not just cosmetic — some roofers handle chimney repointing and rebuilding themselves, others work alongside a bricklayer. If the chimney is still in use for a flue, check whether it needs to stay swept and functional during the work.
Understanding the labour vs materials split
Materials (tiles, felt, leadwork, scaffolding hire) are often a smaller share of a re-roof quote than labour, particularly given the time and access involved. A cheap quote is worth checking for the same tile/material spec as competing quotes, not just a lower labour day rate.
Thatched roofs — a specialist trade
Thatched roofing is its own specialism, not something a general roofer typically covers — thatch has different fire safety, insurance and maintenance considerations (including regular ridge and ongoing coating work) compared to tiled or slated roofs.
Domestic vs commercial roofing work
Most roofers who work on homes also cover garages, outbuildings and small extensions, but larger commercial flat-roof work (warehouses, larger extensions) sometimes needs a roofer with specific experience in bigger membrane systems. Worth asking directly if your job is unusually large or non-standard.
Why roofing work is weather-dependent
Roofers generally can't safely work in high winds, heavy rain, or icy conditions, so scheduled roofing jobs sometimes shift by a few days around bad weather — factor this into timing if you need work finished by a specific date, particularly in autumn/winter.
How long does roofing work take?
A small tile repair is usually a few hours. A full re-roof on an average semi-detached house commonly takes 1-2 weeks including scaffolding, weather permitting — roofing work is one of the more weather-dependent trades, so timelines can shift.
Signs your roof needs attention
Slipped, cracked or missing tiles, sagging in the roofline, daylight visible through the roof from the loft, and damp patches on ceilings are all signs worth having checked. A few slipped tiles is usually a repair; sagging or widespread wear across the whole roof usually points toward a full re-roof being better value than repeated repairs.
Moss and algae on roofs — repair or just clean?
Moss on a roof isn't purely cosmetic — it can hold moisture against tiles and, over years, contribute to wear. Roof cleaning can help on an otherwise sound roof, but heavy moss on an older roof sometimes indicates it's simply due for replacement rather than cleaning being a lasting fix.
