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.
Three steps to hiring the right roofer
First, check NFRC membership or equivalent trade body registration. Second, ask for photos of similar completed jobs, ideally local ones. Third, clarify what happens if underlying roof timbers turn out to need work once the old covering is removed — a very common mid-job discovery.
Roof damage and home insurance
Storm damage to a roof is one of the more common home insurance claims — insurers usually want photos of the damage before repair and may ask whether the roof was in good general condition beforehand. Keep any roofing invoices in case they're needed to support a future claim.
Conservation areas and roofing materials
Even without individual listing, a property in a conservation area can have restrictions on visible roofing changes — different tile colours, added skylights on street-facing slopes, or replacing natural slate with a synthetic alternative. Check with your local planning authority before ordering materials.
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.
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.
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.
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.
