Clay and slate roofs can last 80–100+ years with good maintenance. Concrete tiles typically last 40–60 years. Flat roofs with modern membranes last 20–30 years. If your roof is approaching these ages, get a professional inspection.
In most cases, yes. Health and safety regulations require scaffolding for work at height. Be cautious of roofers who suggest working without it — it is both a safety risk and often a sign of an uninsured operator.
A full roof replacement on a typical 3-bed semi costs £5,000–£10,000 for concrete tiles or £8,000–£15,000+ for natural slate. Costs depend on roof size, access, material choice, and whether structural repairs are needed.
If damage is localised (a few missing tiles, small leak), repair is usually sufficient. If the roof is over 50 years old, has widespread deterioration, or multiple leaks, full replacement is more cost-effective long term.
