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.
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.
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.
Domestic vs commercial roofing work
Most roofers who work on homes also cover garages, outbuildings and small extensions, but larger commercial flat-roof work (warehouses, larger extensions) sometimes needs a roofer with specific experience in bigger membrane systems. Worth asking directly if your job is unusually large or non-standard.
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.
Flat roof vs pitched roof considerations
Flat roofs (felt, GRP fibreglass, or rubber/EPDM) typically need replacing more often than a pitched tiled roof, but repairs are usually quicker and cheaper. A flat roof extension on an older pitched-roof property is common and often uses a different material and roofer specialism than the main roof.
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.
Roof damage and home insurance
Storm damage to a roof is one of the more common home insurance claims — insurers usually want photos of the damage before repair and may ask whether the roof was in good general condition beforehand. Keep any roofing invoices in case they're needed to support a future claim.
