Find the cause · Explain the repair
Leaking roof, slipped tiles or damaged flashing? We repair pitched and flat roofs across London, helping homeowners, landlords and property managers understand the problem and agree the work before it starts.
Free roofing quotations. Formal roof surveys are a separate paid service.
NFRC memberFully insuredWritten roofing quotationsDetailed roof survey reportsDescribe what you have noticed—you do not need to diagnose the fault before contacting us.
Water does not always enter directly above the stain you can see indoors. Roof coverings, junctions and drainage need to be considered together. Tell us when the leak occurs, whether it changes with wind or rain and what has already been tried.
We undertake local repairs to pitched and flat roofs. If the wider condition means repeated patching is unlikely to be a sensible approach, we explain the renewal options as well.
Roof repair costs depend on the defect, materials, affected area and safe access. Scaffolding or other access arrangements can be a significant part of the scope, even where the visible defect is small. We discuss the assessment needed before providing a free written roofing quotation.
Your quotation should identify the proposed work, access and exclusions so you can understand what the price covers. Sending an enquiry does not book a visit or commit you to work.
For a detailed written record of the roof’s condition, ask about a separate paid roof survey. If you mainly want a price for roofing work, start with a roofing quotation.
We welcome roof-repair enquiries across London, with a focus on North, West and Central London. See our local information for Highgate, Hampstead, Barnet, Finchley, St John’s Wood, Marylebone and Mayfair. Share the property postcode so we can discuss access and the appropriate assessment.
Send your postcode, a short description and the history of the problem. Existing photographs, previous survey findings and information about access can help us discuss the next step.
For water actively coming into the property, call our 24/7 emergency line instead of waiting for a form response.
Our roof repair or replacement guide explains the questions to ask about an isolated defect, wider deterioration and further investigation. Before agreeing work, use the roofing quotation checklist to check what the proposed price includes.

Answers to common questions about the next step.
No. An isolated defect may be repairable. Widespread deterioration, repeated failures or problems beneath the covering may need a wider scope. We explain the proposed work and any limits to the assessment so you can decide on the next step.
Call our emergency line to discuss the leak, availability, attendance and charges. Keep clear of affected electrics and do not climb onto the roof. The enquiry form does not reserve an emergency visit.
