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.
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.
Why roofing work is weather-dependent
Roofers generally can't safely work in high winds, heavy rain, or icy conditions, so scheduled roofing jobs sometimes shift by a few days around bad weather — factor this into timing if you need work finished by a specific date, particularly in autumn/winter.
Leadwork around chimneys and valleys
Lead flashing seals the joins where a roof meets a chimney, wall, or valley — a very common source of leaks when it perishes or is poorly installed, even if the roof tiles themselves are fine. If a leak keeps recurring in the same spot near a chimney, it's often the leadwork rather than the tiles that needs attention.
Slate, tile and other roofing materials
Natural slate is durable and often required on period or listed properties for appearance reasons, but costs more than concrete or clay tile. Metal (zinc) roofing suits modern extensions and flat/low-pitch areas. The right material often depends as much on the property's style and any planning restrictions as personal preference.
Moss and algae on roofs — repair or just clean?
Moss on a roof isn't purely cosmetic — it can hold moisture against tiles and, over years, contribute to wear. Roof cleaning can help on an otherwise sound roof, but heavy moss on an older roof sometimes indicates it's simply due for replacement rather than cleaning being a lasting fix.
Background checks and identity verification
Roofing has a higher-than-average rate of doorstep cold-calling scams (particularly after storms), so checking a roofer's trading history, a verifiable business address, and reviews referencing specific local jobs matters more here than for some other trades.
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.
