Common roof problems in London (and how we fix them)
Slate & tile roofs
Issues: Slipped/broken slates or tiles; failing ridge/hip mortar; damaged battens or underlay.
Fix: Replace like-for-like slates/tiles and secure with appropriate fixings; repair battens/underlay; re-bed or mechanically fix ridges/hips.
Flat roofs (Felt, EPDM, GRP)
Issues: Blistering, splits, ponding water, failed seams and joints.
Fix: Cut and patch with compatible membranes, reinstate upstands/drip trims, improve falls where feasible; advise on overlay vs. renewal.
Leadwork & flashings
Issues: Cracked or undersized lead, failed sealant, poor step flashing.
Fix: Re-dress or replace with correctly sized code lead, chase and point properly, ensure correct lap and expansion allowances.
Chimneys & parapets
Issues: Open joints, spalled bricks, defective flaunching/caps.
Fix: Repoint with suitable mortar, rebuild small sections, renew flaunching and caps, add lead soakers/flashings as required.
Gutters & downpipes
Issues: Blockages, leaks at joints, inadequate capacity.
Fix: Clean, re-seal or replace joints/sections, add leaf guards; adjust falls to improve flow.

Fix: Renew flashing kits/seals and refit to manufacturer guidance, then water-test.

Inspections & surveys (including drones)
For high or complex roofs, a drone survey can be the quickest, safest way to understand what’s happening—often without scaffolding. Learn more about our drone roof surveys in London, including typical costs and turnaround times.
Emergency roof leak? Do this first
- Protect the interior: Move valuables; place a bucket; use dust sheets.
- Relieve ceiling bulges safely: If water balloons form, pierce carefully at the lowest point into a bucket (only if safe to do so).
- Isolate electrics if wet: Turn off the affected circuit at the consumer unit and avoid use.
- Call us: Request a same-day make-safe visit to stop further ingress.
- Keep evidence: Photos help with insurance claims.
London-specific considerations
Listed buildings & conservation areas: Many Kensington & Chelsea properties require sensitive methods and, in some cases, consent. We match materials and techniques to maintain character and compliance.
Shared/terraced roofs: Party-wall and access coordination may be needed. We’ll liaise with neighbours or managing agents where appropriate.
Weather windows: Storms can create backlogs; we prioritise make-safe actions, then schedule permanent works in the next safe weather window.
How to prevent future leaks
- Annual roof & gutter inspection: Spot small issues early. After heavy storms, do a quick visual check from ground level.
- Clear gutters in autumn/spring: Prevent overflow and damp ingress.
- Trim overhanging branches: Reduce moss and debris.
- Ensure adequate ventilation: Reduce condensation and timber decay.
Areas we cover
Kensington, Chelsea, Notting Hill, Holland Park, Knightsbridge, Bayswater, Paddington, Maida Vale, Hammersmith, Fulham, Shepherd’s Bush, Earls Court, and surrounding postcodes in Central and West London.
Frequently Asked Questions
How quickly can you attend an emergency roof leak in London?
Often the same day for make-safe works; permanent repairs are scheduled at the earliest safe weather window.
Do I need scaffolding for a small repair?
Not always. For low-risk, short-duration tasks, we may work from towers or ladders with the correct controls. For higher roofs or complex areas, scaffolding is safer and may be required.
Can you match my existing slates/tiles?
We’ll source the closest available match and advise on aesthetics versus performance where exact matches are no longer produced.
Will a patch fix last?
A well-executed patch can provide years of service, but we’ll explain lifespan expectations and whether a larger section is nearing end-of-life.
Do you work on listed properties?
Yes—our approach is sensitive to conservation requirements. If permissions are needed, we’ll advise on next steps.
