Does your roof need repairing or replacing?

Repeated leaks, worn coverings and a history of repairs can be reasons to consider a wider renewal. They do not all lead to the same specification. We assess the condition, discuss what can be retained and explain the proposed scope.

Our work covers slate and tiled pitched roofs as well as flat-roof renewals. A terrace, an extension and the roof of a residential block have different details and access needs.

What your roof replacement quotation should include

The quotation should identify the work included and any exclusions. If underlying damage is revealed during the work, the response needs to be assessed and agreed.

  • The proposed slate, tile or flat-roof covering
  • Underlay, battens and ventilation where relevant
  • Ridges, hips, valleys, eaves and edge details
  • Chimney junctions, flashings and adjoining roof levels
  • Scaffolding, access and removal of old materials

Plan access and disruption early

Tell us about occupied flats, shared entrances, garden access and any restrictions affecting the property. These details help establish the arrangements for scaffolding, deliveries and waste removal.

We discuss the proposed programme and applicable guarantee arrangements before work is agreed. Insurance-backed guarantees are available for eligible work; the relevant cover and terms need to be confirmed for your specification.

Compare the work behind each quotation.

Preparation, access, the layers beneath the covering and roof details can make two replacement proposals very different. Use our eight-point roofing quotation checklist to compare the scope. If you are still weighing up a local repair, the repair or replacement guide sets out the questions to ask first.

Common questions about roof replacement

Answers to common questions about the next step.

Can the existing tiles or slates be reused?

Sometimes. Their condition, suitability and the proposed work determine what can be retained. We discuss this as part of the specification.

How much does a roof replacement cost?

Roof size, covering, access, complexity and the condition of the construction all affect the price. Scaffolding, removal of existing materials and the roof’s junctions also affect the scope. We provide a free written quotation based on the proposed work rather than a generic estimate from the postcode alone. Include any existing report and photographs when you enquire.

Is a flat-roof renewal different from a tiled roof replacement?

Yes. The materials, construction and details differ. We will discuss the appropriate scope for your roof; the flat-roofing page shows more of that work.

Should I book a survey first?

A separate paid condition report can be useful if you need a documented assessment before planning major work. A roofing quotation is the route for a proposed scope and price.
