Roof ventilation, why it matters
Poor roof ventilation can lead to condensation build-up in the loft space, which over time causes timber rot — a factor a roofer will often check during a re-roof, since it's a much cheaper fix to address at that point than as a standalone later repair.
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.
Gutter clearing vs gutter replacement
Blocked gutters from leaves and debris are usually a clearing job, not a replacement one — worth getting cleared before assuming new guttering is needed. Persistent overflow even when clear, or visible sagging/cracking, points toward the guttering itself needing replacement rather than just clearing.
Seasonal roof checks worth doing
Before winter: check for loose tiles and clear gutters, since blocked gutters and ice are a common combination for damage. After a storm: a visual check from the ground for obvious damage, before assuming everything's fine just because there's no visible leak yet.
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.
Understanding the labour vs materials split
Materials (tiles, felt, leadwork, scaffolding hire) are often a smaller share of a re-roof quote than labour, particularly given the time and access involved. A cheap quote is worth checking for the same tile/material spec as competing quotes, not just a lower labour day rate.
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.
Roof insulation, where it goes
Loft insulation (laid flat, cheap, effective) is different from insulating the roof slope itself (needed if the loft is being converted into living space). A re-roof is often the most cost-effective time to upgrade roof-level insulation, since the covering is already off.
