Roofing contractor disputes — leaks, overcharging, and the storm-chaser pattern
The short answer: roofing disputes combine the highest-stakes defect (water in the building) with the highest-pressure selling (doorstep "we're working next door" pitches and storm-chasing after bad weather). The evidence rules are strict: photographs during rain, honest inspection records, and quotes from roofers who actually went up the ladder.

The five classic failure points
1. Flashings and abutments — leadwork missing, wrongly dressed, or mastic-smothered (a tell of a botched job). Leaks at the chimney/parapet line follow. 2. Valleys and falls — valley gutters too small, wrongly laid, or felt/underlay not dressed into them. 3. Overcharging scams — "your whole roof needs replacing" after a ladder inspection of one slope; invoices inflated with invented items ("re-bedded all ridge" when nothing was touched). Get an independent roofer's opinion before agreeing to major work — and definitely before paying. 4. Storm-chaser pattern — unmarked vans after storms, cash-only, "spare materials left over from next door", pressure to decide now. These operations appear and dissolve; report via Citizens Advice → Trading Standards and pay by traceable means. 5. Incomplete work mid-storm — roof opened, battens off, tarpaulin inadequate: emergency make-safe costs are recoverable (see builder walked off the job).
Evidence that wins a roofing dispute
- Rain-day photos/video of the active leak, inside and out — a dry-weather photo of a stain is weaker than a video of water entering.
- Before/after pairs — the roofline before work (street photos, estate-agent photos, Google Street View history all count) versus after.
- The itemised invoice against the itemised quote — line-by-line comparison exposes invented items.
- Independent roofer or surveyor inspection — written report; RICS Find a Surveyor for chartered reports.
- Scaffold photos — was there actually scaffolding where the invoice says it was hired?
The overcharge fight
If you've been invoiced far beyond the quote: don't pay the excess while disputing; send a written breakdown of what you accept and what you dispute (your schedule of loss logic in reverse — line-by-line challenge); demand the original fixed quote terms. Then small claims for the balance wrongly withheld/demanded.
The doorstep-roofer emergency rules
- Never decide on the doorstep; a genuine roofer will put a fixed quote in writing.
- Check the firm on Companies House and TrustMark before any payment.
- Pay nothing beyond a small deposit by traceable means; never cash for storm repairs.
