Pitched roof
North Bristol
Full strip & re-tile
Electronic survey pinpointed two failed valley flashings. Full strip, new breathable underlay, clay replacement tiles matched to original profile.
How it works
Three clear steps from first call to guaranteed result — no guesswork, no hidden extras.
-
Book a diagnostic survey
Call or message us with your postcode and what you’ve noticed. We confirm a visit time — often same or next day for urgent cases.
-
Receive your written report
After the survey you receive a written report with diagnostic images, the confirmed leak source, and an itemised fixed-price quote — before any work begins.
-
Approve the scope — we deliver
You sign off the agreed spec. Our insured crew completes the repair with zero hidden extras. Workmanship is guaranteed in writing on every contract.
Technology-led surveys
Bristol City Roofing pairs certified roofers with professional-grade diagnostic equipment — the same class of tooling used in building envelope and flat-roof commissioning. Whether you have a stubborn flat-roof leak, suspected membrane breach or complex pitched detail, we build a picture from data first.
That feeds straight into a written scope: materials, methodology, and access plan — so you can compare quotes fairly and sign off work with confidence.

Don’t just take our word for it
Representative of typical feedback after diagnostic-led projects — drawn from the kind of detail clients leave on Google and Checkatrade.
-
They showed us thermal images and explained exactly why water was tracking — the repair was scoped to one detail, not half the roof. Saved us a fortune.
-
Finally a roofer who leads with data. Report was clear enough to share with our insurer; the crew finished clean and on programme.
-
We’d had three roofers fail to find the source of a slow leak over 18 months. Bristol City Roofing attended, ran their electronic survey across the roof in under an hour, and showed us exactly where water was entering — a split flashing behind a parapet that nobody had even looked at. The repair was targeted, fast, and the ceiling has been dry ever since. Cannot recommend them highly enough.

Chimney & parapet leadwork
Three previous roofers failed to find the source. Diagnostic kit traced water entry to a split soaker behind the chimney stack — targeted repair, dry ever since.
Evidence over assumption
Our reputation is built on clarity: you see what we see, and you approve scope before major spend. That’s how we keep rework low and outcomes high — on homes, portfolios and commercial roofs alike.

Why diagnostic-led roofing wins
See how our data-first approach compares against the alternatives across five critical factors.
| Criterion | Bristol City Roofing | Typical roofer | DIY |
|---|---|---|---|
| Leak detection method | Electronic & thermal survey — source confirmed before lifting a tile | Visual inspection — experience-based estimate | Guesswork — strip and hope |
| Accuracy | Pinpoint — mm-level moisture mapping | Area-level — may over-scope work | Low — trial and error |
| Cost certainty | Fixed-scope written quote before any work starts | Estimate may change on opening up | Unknown — materials, time & repair costs unpredictable |
| Repeat call-backs | Low — root cause fixed, not patched | Possible — patch-first approach | High — wrong area, wrong fix |
| Guarantee | Written workmanship guarantee, fully insured | Varies — ask for it in writing | None |
Results that speak for themselves
Diagnostic-led repairs leave no ambiguity — the source is confirmed before a tile is lifted, and the result is documented on completion.

Thermal survey & pinpoint repair
Leak source confirmed by thermal scan. Only the failed section opened — replaced to specification.

We invest in equipment calibration, safe systems at height, and ongoing training — because precision tooling only matters when the team interpreting it knows roofs inside out.
