Roof orientation and solar suitability
A south-facing roof slope generally gets the most useful sun for solar panels, though east/west-facing roofs can still work reasonably well. A roofer or solar installer assessing suitability will look at pitch, orientation, shading from nearby trees or buildings, and roof structural capacity together.
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.
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.
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.
Scaffolding — why it's often a separate cost
Scaffolding is frequently quoted separately from the roofing work itself, priced by roof height, access and how long it's needed. For a small repair some roofers use a tower or ladder instead, but anything involving a full re-roof or significant chimney work usually needs full scaffolding for safety and building regulations reasons.
Chimney repairs and rebuilds
A leaning or spalling (crumbling brick) chimney is a structural safety issue, not just cosmetic — some roofers handle chimney repointing and rebuilding themselves, others work alongside a bricklayer. If the chimney is still in use for a flue, check whether it needs to stay swept and functional during the work.
Roofing on extensions and new builds
A new roof needs to tie into the existing structure correctly at the junction — a common source of leaks on extensions is poor detailing at exactly this point, not the new roof covering itself. Timing roofing work before internal trades start avoids water damage to work done underneath.
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.
