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.
What affects the cost
Cost depends on roof size and pitch (steeper roofs need more scaffolding and take longer), the material (slate costs more than concrete tile), access, and whether the existing roof structure (timbers, felt) needs work too, not just the visible covering. A straightforward repair is quick; a full re-roof including scaffolding commonly takes 1-3 weeks.
Scaffolding — why it's often a separate cost
Scaffolding is frequently quoted separately from the roofing work itself, priced by roof height, access and how long it's needed. For a small repair some roofers use a tower or ladder instead, but anything involving a full re-roof or significant chimney work usually needs full scaffolding for safety and building regulations reasons.
What a good roofing quote should include
A proper quote should specify materials (tile type, felt/underlay grade), whether scaffolding is included or separate, what happens to existing timbers if they're found to be rotten once work starts, and the guarantee length on both materials and workmanship.
How roofing quotes work
An initial estimate can be given from photos or a description, but a firm price for anything beyond a very small repair usually needs the roofer to inspect the roof in person, often from the ground with binoculars or a drone rather than climbing up for a quote visit.
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.
Gutter clearing vs gutter replacement
Blocked gutters from leaves and debris are usually a clearing job, not a replacement one — worth getting cleared before assuming new guttering is needed. Persistent overflow even when clear, or visible sagging/cracking, points toward the guttering itself needing replacement rather than just clearing.
Flat roof vs pitched roof considerations
Flat roofs (felt, GRP fibreglass, or rubber/EPDM) typically need replacing more often than a pitched tiled roof, but repairs are usually quicker and cheaper. A flat roof extension on an older pitched-roof property is common and often uses a different material and roofer specialism than the main roof.
