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.
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.
Roofing on listed and period properties
Listed building consent is often required to change roofing material (even like-for-like sometimes needs approval if the material is being sourced differently), and conservation areas can restrict visible changes like skylights on street-facing roof slopes. Check with your local planning authority before committing to a material change.
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.
Leadwork around chimneys and valleys
Lead flashing seals the joins where a roof meets a chimney, wall, or valley — a very common source of leaks when it perishes or is poorly installed, even if the roof tiles themselves are fine. If a leak keeps recurring in the same spot near a chimney, it's often the leadwork rather than the tiles that needs attention.
What NFRC membership means
The National Federation of Roofing Contractors is the largest UK roofing trade body, representing over 60% of the industry. NFRC members are vetted on technical competence and financial standing, and some offer an insurance-backed guarantee on top of their own workmanship guarantee — worth asking whether this applies to your quote.
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.
Common roofing jobs
Roofers handle full re-roofs, repairs to individual slipped or cracked tiles, flat roof replacement, guttering, fascias and soffits, and leadwork around chimneys and roof valleys. Emergency work — storm damage, a leak during heavy rain — is usually handled separately from planned re-roofing.
