Roof replacements in London

A new roof is a major decision. We help you understand the options and plan a complete renewal around the condition and character of your property.

A considered approach to a new roof.

Repeated leaks, ageing coverings and a history of patch repairs can point to a roof that needs more than another local repair. We assess the covering and accessible details, discuss what can be retained and set out the proposed renewal in a written quotation.

Our work covers slate and tiled roofs on houses, residential blocks and commercial buildings across Central and North London. The choice of covering matters, but so do the underlay, battens, ventilation and weathering details beneath and around it.

More than replacing the covering

A renewal is an opportunity to assess the roof as a whole. The scope should explain the treatment of the roof edges, ridges, valleys, chimney junctions and rainwater drainage, alongside the main covering. Any underlying damage revealed during the work needs to be assessed and agreed.

  • Slate and tile coverings suited to the roof and property
  • Underlay, battens and appropriate roof ventilation
  • Ridge, hip, valley and eaves details
  • Associated leadwork, chimney flashings and drainage

Plan the access as carefully as the roof

Scaffolding, deliveries and waste removal can be a substantial part of a London roofing project. Tell us about shared access, neighbours, occupied flats and any restrictions. We discuss these at quotation stage so the proposed arrangements are clear.

Clear scope, before work starts

Your quotation will set out the proposed work and exclusions. We discuss the specification, the programme and any applicable guarantee arrangements before you commit. If a building has special constraints, share these at the start so they can be considered in the project planning.

Your questions

A little clarity, before you decide.

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

Can existing slates or tiles be reused?

Sometimes, depending on their condition, suitability and the proposed work. Reuse should be assessed as part of the specification. We will explain what can realistically be retained and what needs replacing.

How much does a new roof cost?

Roof size, covering, access, complexity and the condition of the underlying construction all affect the cost. Send your postcode and details of the property so we can arrange the information or inspection needed for a written quotation.

Will I need to move out?

That depends on the building and scope. Tell us how the property is occupied so we can discuss access, protection and disruption before agreeing a programme.
