Roof repairs in London

A leak needs a clear diagnosis and a sensible repair. We assess the affected roof and explain what needs attention, from a slipped slate to a failing flashing.

Find the issue. Repair with care.

Water inside a property does not always enter directly above the stain. The covering, junctions, drainage and nearby roof details all need consideration. Tell us when the leak appears, whether it changes with wind or rain, and what repairs have already been attempted.

We undertake repairs to pitched and flat roofs, including local slate and tile defects, weathering details, ridges, valleys and associated rainwater goods. If the condition points towards wider renewal, we explain that too.

Common roof repairs

The right repair depends on the roof’s condition and the cause of the defect. We can assess problems affecting the main roof covering and the details around it.

  • Slipped, cracked or missing slates and tiles
  • Leaks around chimneys and roof junctions
  • Deteriorated ridge, hip and verge details
  • Valley and parapet gutter defects
  • Local flat roof damage and failed edge details

A repair that fits the roof

Before recommending work, we consider how the damaged area connects with the surrounding roof. An isolated defect may be suitable for a local repair, while widespread ageing can make repeated patching less useful. We set out the proposed scope so you can decide how to proceed.

What to send when you enquire

Your postcode, a description of the problem and when you first noticed it are a useful start. If you have photographs taken safely from inside or ground level, you can email them to the team. Tell us about any roof access and whether the property is a house, flat or commercial building.

Your questions

A little clarity, before you decide.

If you have a specific concern about your roof, tell us when you enquire.

Can you help with a roof that has been repaired before?

Yes. Let us know what was done, when it was done and whether the leak changed afterwards. Previous photographs or invoices can help us understand the history, alongside an assessment of the roof.

Do you handle small roofing repairs?

Yes. We assess local defects as well as larger roofing work. Safe access and the location of the defect influence how a repair can be undertaken and quoted.

What if the leak is urgent?

Please call us. We will discuss the circumstances and confirm availability. Online enquiries do not reserve an emergency visit.
