A complete roof renewal

Flat Roof Replacement

When an old covering has reached the end of a practical repair life, a planned replacement provides the chance to correct damaged decking and rebuild the waterproofing from a sound base.

Is it right for your roof?

Where this service can make sense.

Every flat roof needs to be assessed on its own condition, construction and details. These are common situations where this service may be considered.

  • Repeated leaks across an older roof
  • Widespread cracking or failed covering
  • Soft, damaged or unsuitable roof decking
  • Extensions and newly formed flat roofs
  • Roofs with several previous patch repairs
  • Full upgrade to a modern felt system

The working process

From first inspection to finished roof.

The exact method depends on the existing roof, but the work follows a clear sequence focused on preparation and waterproof detailing.

  1. 01

    Survey the complete roof

    The covering, deck, falls, edges and drainage details are reviewed before the replacement is planned.

  2. 02

    Strip back where required

    Failed materials are removed carefully to expose the condition of the roof structure and deck.

  3. 03

    Repair or renew the deck

    Unsound deck areas are replaced to create a firm, even base for the new waterproofing system.

  4. 04

    Install the new roof

    The selected system is installed and finished around every edge, junction, outlet and penetration.
