The Project

The Challenge

Graham Ellis Associates (GEA) were commissioned by The Sigma Trust on behalf of Monkwick Infant School for an urgent Roofing Upgrade Project.

An intrusive and comprehensive survey was carried out, with core samples taken, to identify those roofs and windows which were in need of urgent repair/replacement.

The Remedy

An intrusive roof survey was carried out, taking core samples which indicated 1,230m2 of the flat roofing area was designated Grade D (marked red on plan) which was in need of immediate replacement. An initial budget was set of £252,500.00 to include replacement flat roofs, roof lights and removal of asbestos.

Scope of Works

GEA were tasked with providing the most cost-effective solution to deal with the defective roofs and the problems encountered by the leaking roofs at the School.

An overlay roofing system was adopted, which would cause minimal disruption to the teaching and learning curriculum and also carried a 30-year guarantee.

The works comprised the following:

  • Preparing the existing roof surface to accept new waterproofing.
  • Installing overlay roofing system
  • Insulating the roof areas to current building regulation standards.
  • Re-routing cables.
  • Raising soil and vent pipes.
  • Raising window thresholds.
  • Improving drainage/falls to roofs.
  • Installing new edge details.
  • Removal and capping of non-compliant roof lights (where required).
  • Providing rainwater outlets and down pipes where indicated.
  • Installing all necessary flashings.
