Flat Roof Construction

Generally a flat roof is defined as having a pitch no greater than 15° to the horizontal. Most flat roofs have some degree of angle in order to allow rainwater to drain away.

There are several materials available to apply a waterproof layer to the flat roof construction. Here at Mike Carroll roofing and building services we prefer to use an EPDM (Ethylene Propylene Diene Monomer) rubberised sheet.

A typical flat roof construction consists of six basic elements.

  1. A water resistant membrane
  2. Some form of thermal insulation to retain the heat within the building.
  3. A vapour barrier.
  4. A plywood timber deck which allows the roof to support a load.
  5. Wooden joists which are supported by the walls.
  6. Plasterboard ceiling

Typical applications for this type of construction would be Garage Roof, Porch, single storey extensions. Here at Mike Carroll Roofing and Building Services we also utilise this construction method for our bespoke summerhouses.

Rubber Flat Roof Systems

For all our Flat Roof Repair or Replacement projects we use the Hertalan rubber roof easy deck system. Their EPDM rubber sheeting is a synthetic rubber made from the refinery by-products ethyl and propylene so it’s both biologically and ecologically safe and comes with a manufacturers 20 year guarantee – although in a SKZ study in March 2001 suggests a 50 year life span for the system.

Hertalan is the ideal material for, flat roof repair or replacement projects as it is an environmentally friendly waterproofing system and it offers far better insulation properties compared to conventional flat roof constructions. It is lightweight and quick to install as the membranes are pre-fabricated to the correct size.

Wherever possible, for all our Flat Roof Repair or Replacement services, we use our own safety tower saving you the cost of hiring scaffolding.
