Roofing felt vs breathable membrane
Older roofs often used bituminous felt underneath the tiles, which can perish and needs replacing during a re-roof; modern breathable membrane lasts longer and manages moisture better. If you're having a full re-roof, this underlay is worth confirming as part of the spec, not just the visible tiles.
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.
Roofing considerations before fitting solar panels
If a roof needs re-covering within the next 5-10 years, it's usually more cost-effective to do that before fitting solar panels rather than after, since removing and refitting panels for a later re-roof adds cost. Worth asking a roofer to assess roof condition before committing to solar installation timing.
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.
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.
Common roofing myths, busted
"A few loose tiles are always urgent" — sometimes, but not always; a roofer can usually tell you if it can wait for a scheduled visit. "Moss means the roof needs replacing" — not necessarily, see roof cleaning above. "Flat roofs always leak eventually" — modern EPDM/rubber flat roofing lasts decades if properly installed.
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.
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.
