Signs your roof needs attention
Slipped, cracked or missing tiles, sagging in the roofline, daylight visible through the roof from the loft, and damp patches on ceilings are all signs worth having checked. A few slipped tiles is usually a repair; sagging or widespread wear across the whole roof usually points toward a full re-roof being better value than repeated repairs.
Roofing felt vs breathable membrane
Older roofs often used bituminous felt underneath the tiles, which can perish and needs replacing during a re-roof; modern breathable membrane lasts longer and manages moisture better. If you're having a full re-roof, this underlay is worth confirming as part of the spec, not just the visible tiles.
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.
Red flags in a cheap roofing quote
A quote well below others, unsolicited doorstep cold-calling (especially "I noticed a problem while working nearby"), demands for cash up front before any work starts, and no fixed business address are all worth treating with caution — roofing is a trade with a higher-than-average scam rate.
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.
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.
Aftercare after roofing work
Ask for photos of the completed work (roofers can see angles you can't from the ground) and keep any guarantee paperwork with your house documents. It's worth a visual check from the ground after the first heavy rain to confirm guttering is draining properly.
Pest and vermin entry points in roofs
Gaps around fascias, damaged soffit vents, or missing tiles are common entry points for birds, squirrels and other vermin into a loft space — a roofer doing repair work will often flag these even if they weren't the original reason for the call-out.
