Emergency roof leak repair in London
Rain coming in, damaged roof covering or a gutter overflowing into the building?
Homes, businesses, landlords and managing agents. One number for the fault, the visit and the next repair step.
1-hour arrival aim, subject to availability. Give us your postcode and fault for the available visit time and charge. Call for an active emergency; the form does not dispatch help.
With a roof leak, the first priority is the safety of people beneath it and a workable access plan. Tell us where water enters, the building height and whether anything is loose or falling. We arrange roofing attendance and discuss the earliest safe work window.
When to call
Problems we can help with
- Active roof leaks during or after rain
- Storm-damaged tiles, slates or flashing
- Leaking flat-roof details
- Failed or blocked rainwater goods causing water ingress
Safety first
While you arrange help
Keep clear of sagging ceilings and falling debris. Do not climb onto the roof or use a ladder in dangerous weather. Keep away from water near electrics. Call 999 for immediate danger to people.
What the visit can include
- Assess the reported leak and access from a safe position.
- Arrange suitable temporary weather protection where practical.
- Explain the permanent repair scope, materials and access needed.
24/7 contact does not mean roof work is safe at every hour. Wind, rain, darkness, height and access equipment can delay physical repairs. Temporary protection and a permanent repair are different scopes.
Detailed roofing repair guides & local areasTell us these details when you call
- How high is the roof and is the leak over an occupied room?
- Is anything visibly loose, bulging or falling, viewed from a safe place?
- Are there existing roof-access arrangements, a caretaker or a managing agent?
Add the full postcode, a safe contact number and who can arrange entry. Send photos only if you can take them safely.

Commercial maintenance solutionsEmergency repair questions
Can I call Mayfair 24 hours a day?
Yes. Contact Mayfair 24/7 for emergency and reactive maintenance across London, including evenings, weekends and bank holidays. Describe the fault and give your full postcode so attendance can be arranged.
How quickly can someone arrive?
We aim for arrival within 1 hour where available. Timing depends on your postcode, the specialist required, current availability and travel conditions. Safe access and weather also affect roofing and other external work. We explain the expected attendance when you call.
How much does an emergency repair cost?
Call for the charge for your fault and attendance time, including VAT and what the visit covers. Our small-repair offer starts from £85 including VAT for eligible accessible jobs; it is not a fixed price for every emergency. Parts, specialist equipment and further work are priced separately and need your approval.
Can a roof be repaired during heavy rain?
Sometimes work must wait for safer weather or suitable access equipment. The team will discuss what can be done safely to limit damage and when the roof itself can be inspected or repaired.
Can I send an emergency through the form?
Call for an active emergency. The form is useful for supporting details or a non-immediate repair, but it does not dispatch an engineer or book attendance.
