How we diagnose leaks quickly
- Triage: when it started, weather patterns, and where symptoms show.
- Visual survey: ground and safe roofline checks for tiles, flashings, and gutters.
- Moisture mapping: pin/pinless meters to trace the spread and direction of damp.
- Thermal imaging: highlights hidden cold/damp paths (where conditions allow).
- Drone survey: fast views of hard-to-reach or fragile areas (where lawful).
- Targeted tests: hose isolation, UV dye, or smoke tests to confirm the entry point.
- Micro-inspection: borescope to see inside voids and tricky junctions.
- Clear plan: photos/video, make-safe options, and a fixed repair proposal.

What we fix same day vs. follow-up
- Same day: slipped/broken tiles, small flashing issues, gutter reseals/clears, emergency covers.
- Follow-up: flat-roof recover/overlays (EPDM/GRP/felt), valley liners, chimney works, ridge/hip rebedding, skylight replacement, larger leadwork.

What we work on
- Pitched roofs, valleys/abutments, chimneys/leadwork, flat roofs (felt/EPDM/GRP), skylights/Velux, gutters/downpipes, and condensation issues often mistaken for leaks.

Why Speed Matters For Leak Diagnosis

Water ingress escalates quickly. Within hours it can:

  • Damage plaster, timber, and insulation
  • Trigger electrics issues and safety risks
  • Encourage mould and condensation problems
  • Increase repair costs the longer it is left

We prioritise same-day or next-day call-outs across Milton Keynes, Newport Pagnell, Bletchley, Great Linford, Stony Stratford, Bradwell, Bedford, Luton, Northampton and nearby villages. Most leaks can be diagnosed within minutes of arrival. We either repair on the spot or protect the area until a permanent fix is installed.

Our Rapid Leak-Diagnostic Process

Here is how we find leaks quickly – without guesswork:

  1. Triage and history
    • We listen: when did the leak appear, and under what weather conditions
    • We map internal symptoms to likely roof zones
  2. Visual survey – ground and roofline
    • Safe ladder inspection to spot cracked tiles, failed flashings, slipped slates, degraded flat-roof coverings, blocked gutters, missing verge mortar, ridge issues
  3. Moisture mapping
    • Pin and pinless moisture meters measure the spread of damp behind finishes
  4. Thermal imaging
    • Infrared cameras highlight cold and damp anomalies that reveal hidden paths
  5. Drone survey (where suitable and lawful)
    • High-resolution images for inaccessible or fragile areas
  6. Targeted leak tests
    • Hose isolation, UV tracer dye, or smoke tests to pinpoint the entry point
  7. Micro-inspection
    • Borescope cameras to view hidden voids and tricky abutments without damage
  8. Confirmed diagnosis and plan
    • We show photos or video, explain the cause, and outline immediate and permanent repair options with a clear quote

Specialist Tools We Use

  • Thermal imaging cameras – reveal damp cooling patterns and hidden ingress routes
  • Moisture meters – quantify damp levels and track movement
  • Drones – inspect tall or complex roofs quickly and safely
  • Borescopes – see inside voids, rooflight upstands, and underlay laps
  • Hose isolation tests – simulate rainfall on specific sections to pinpoint failures
  • UV tracer dye and smoke tests – track leaks through flat-roof build-ups
  • Lead probes and flashing tools – confirm movement, cracks, and capillary action
  • Safe access kit – tied ladders, roof ladders, harnesses, debris protection, and tarps

Common Leak Sources: How We Test and Confirm

Pitched tiled or slate roofs

  • Likely causes: slipped or broken tiles, failed underlay at eaves, ridge or hip mortar failure, porous tiles, inadequate laps, storm damage
  • How we confirm: course-by-course visual checks, underlay inspection from the loft where safe, moisture mapping, section-by-section hose tests

Valleys and abutments

  • Likely causes: blocked or split valley liners, poor mortar fillets, defective soakers or step flashings
  • Confirmation: borescope at valley edges, hose tests starting low and moving uphill, flashing probes to test movement

Leadwork and chimneys

  • Likely causes: cracked lead soakers or flashings, poor chasing, failed mortar, porous stacks, missing trays or caps
  • Confirmation: close-up inspection, pointing probe tests, hose isolation for each face of the stack, thermal checks for damp behind the breast

Flat roofs – felt, GRP, EPDM

  • Likely causes: blisters, splits, perished laps, ponding, failed trims, penetrations, poor detailing at upstands
  • Confirmation: visual walkover where safe, smoke or dye tests, thermal imaging after rainfall or early morning

Skylights and roof windows

  • Likely causes: perished gaskets, incorrect flashing kits, poor installation on uneven tiles, blocked drainage channels
  • Confirmation: level and upstand checks, step-by-step hose tests from low to high, borescope behind linings

Gutters, downpipes, fascias, and soffits

  • Likely causes: blockages, misaligned joints, failed seals, undersized outlets, inadequate falls
  • Confirmation: flow tests, joint checks, downpipe camera where needed, assessment of splash patterns and water staining

Condensation mistaken for leaks

  • Likely causes: poor ventilation, missing vapour control layers, thermal bridges, bathroom extract issues
  • Confirmation: hygrometer readings, thermal imaging, inspection of vents and roof ventilation pathways, checks on extract fans and ducting

What We Fix Immediately vs. What Requires Follow-Up

Immediate same-visit fixes we often complete

  • Replacing cracked or slipped tiles or slates
  • Re-seating or re-fixing loose verge caps or minor ridge issues
  • Small flashing repairs and localised sealant detailing where appropriate
  • Clearing gutters and downpipes and resealing leaking joints
  • Temporary covers – tarpaulins or patching to make the property watertight

Follow-up works we schedule promptly

  • Flat-roof overlays or full recover – EPDM, GRP, or felt systems
  • Valley liner replacements and major chimney repointing or rebuilding
  • Re-bedding and repointing ridge or hips, extensive re-tiling
  • Skylight replacement or re-installation with correct flashing kits
  • Larger-scale leadwork or structural remedial work

Compliance: Building Regulations, Materials, and Safety

Your roof must protect your home and comply with UK Building Regulations. We follow best practice on every job and advise when notifications apply.

  • Part C – Moisture: detailing that prevents rain ingress and manages condensation risk with correct ventilation routes and vapour control
  • Part F – Ventilation: ensuring roof spaces breathe correctly to avoid mould and condensation
  • Part A – Structure: when coverings or detailing change load, we assess underlying structure
  • Part L – Energy Efficiency: if more than 25 percent of a roof is refurbished or replaced, insulation and potential notification may be required
  • Fire safety on flat roofs: systems with appropriate fire performance and installation to guidance
  • Building Control or Competent Person schemes: we liaise with the local authority or self-certify where applicable and issue compliance certificates after completion
  • Insurance and safety: fully insured, risk-assessed working, safe access, tidy site management

Before We Arrive: Quick Steps to Limit Damage

  • Move valuables and soft furnishings away from the affected area
  • Place a bucket or tray under drips and protect floors with towels
  • Turn off affected lighting circuits if water is near electrics – do not touch wet fittings
  • Take photos for your records and insurance
  • Please do not go on the roof – stay safe and leave access to us

Fast Case Studies

  • Bletchley – valley leak found in 7 minutes: heavy staining under a valley. Hose isolation confirmed a split liner 1.2 m above eaves. We installed a new valley trough and corrected tile seating – dry since.
  • Newport Pagnell – flat roof blister: intermittent leak after sun and rain cycles. Thermal imaging and dye testing confirmed water tracking from a blistered felt lap. Local recover completed and ponding addressed with improved falls.
  • Great Linford – chimney flashing: wind-driven rain causing damp patches. Step flashing had lifted from the chase. We refixed and sealed correctly, repointed, and re-weathered the stack cap – issue resolved.

FAQs: Roof Leak Detection and Repairs

Can you find a leak while it is raining
Yes. Rain can help confirm the source. We work safely and can often diagnose even during bad weather.

How long does diagnosis take
Initial diagnosis usually takes minutes. We often confirm with targeted tests during the same visit.

Do you charge for quotes
No. Inspections and quotes are free and no-obligation across our service area.

Can you repair the leak on the same day
Often yes for minor issues. If larger works are required, we make the roof safe and watertight and schedule a prompt return.

Do I need Building Control for a repair
Small like-for-like repairs normally do not. If refurbishing over 25 percent of the roof or changing structure or material performance, Building Control may be needed. We advise case by case.

Do you work on all roof types
Yes – tile, slate, EPDM, GRP or fibreglass, felt, and metal. We also repair skylights, chimneys, gutters, and fascias and soffits.

Are you insured
Yes. We are fully insured and follow safety-first procedures on every job.

Which areas do you cover
All of Milton Keynes plus Northampton, Bedford, Luton, and surrounding towns and villages.
