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 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.
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.
Roofing regulations, FAQ
Do I need planning permission for a new roof? Usually not for like-for-like replacement, but altering the roofline, adding a dormer, or working on a listed building often does. Do I need Building Regulations sign-off? Yes for most re-roofing work involving insulation changes — a competent roofer will handle or advise on this.
What a roof survey actually checks
A proper roof survey looks beyond the visible tiles — timber condition in the loft, flashing around chimneys and valleys, ventilation, and signs of past repairs. Worth requesting one before buying a property with an older roof, since problems aren't always visible from ground level or even from inside the loft.
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.
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.
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.
