The Alliance Approach

Experience On The Roof.
Accountability On The Ground.

A roof is a system, not just a covering. Water finds the weak point: a chimney junction, a loose tile, a low upstand or a blocked outlet. We look at how those details work together before recommending a repair.

With 22+ years in roofing, we carry out the work with our own team. The owner oversees projects and the final sign-off, so the conversation stays connected from your first enquiry to the finished roof.

  • Repairs and replacements assessed on condition
  • Slate, tile and specialist flat-roof systems
  • Work kept in-house with owner oversight
  • London and Surrey contact addresses

Repair Or Replace?

Start With The Condition. Not An Assumption.

A local repair may be enough when the surrounding covering and structure are sound. A roof with repeated leaks, failing fixings or water trapped beneath its membrane needs a wider assessment. The right answer comes from understanding the failure, not choosing the biggest job.

For flat roofs, we consider drainage, deck condition, rooflights and thresholds alongside the waterproof layer. On pitched roofs, the valleys, ridges, chimneys and flashings need the same care as the tiles or slates. We’ll explain the proposed work and what can be retained.

Your Questions

Good To Know
Before We Start.

Need to discuss something specific to your roof?

Speak To Our Team
Do I Need A Repair Or A New Roof?

That depends on the condition around the defect, not just the size of the leak. A local repair can be sensible when the surrounding covering, fixings and structure remain sound. If several parts are failing or moisture is trapped within the build-up, a more extensive renewal may be appropriate. We assess the roof before recommending the scope.

Which Areas Do You Cover?

We cover London, Surrey and Berkshire, with contact addresses in South Kensington and Cobham. Our areas directory lists the places we serve. Give us your property postcode when you enquire so we can discuss access and arrange the appropriate next step.

Can I Send Photographs Before A Visit?

Yes. Photographs of the roof and the inside symptom can be useful, provided they are taken safely from the ground, a window or an accessible loft. Send the postcode, explain when the problem started and mention any recent work. Do not climb onto a wet or damaged roof to obtain photographs.

Do You Have An Emergency Contact Number?

You can contact us about roofing emergencies on 07553 337796 at any time. Tell us if water is near electrical fittings, if a ceiling is sagging or if loose materials could fall. Attendance and the work possible on arrival depend on the location, weather and safe access.

Who Will Carry Out The Roofing Work?

Alliance Roofing London keeps roofing work in-house. The owner oversees projects and the final sign-off. Your agreed scope should identify the roof sections and details being worked on, along with any parts that are being retained.
