Components of a Commercial Roofing System

Commercial Roofing Structure

Most flat or low-sloping commercial roofs consist of three principle components: one or more weatherproofing layers on the top to prevent water from penetrating the deeper layers of the roof and usually fitted with an extra layer of surfacing to protect those deeper layers from the sun and the wind and a reinforcement layer to add strength and stability. Depending on the type of the commercial roof, the components are made from different material:

  • Built-up roofs – this type of roofing consists of alternated layers of sheets made from tar or other suitable material and gravel or liquid surfacing;
  • Modified bitumen roofs – these roofs use sheets of modified bitumen adhered with a roofing torch. Modified bitumen is more resistant and more durable than conventional bitumen;
  • Foam roofing – these roofs consist of a decking on which a suitably thick layer of polyurethane foam is applied from a large spraying gun and then granules and various top coatings are added for weatherproofing and enhanced protection against impact, UV radiation, wind and water;
  • EPDM roofs – also known as rubber roofs, these systems use sheets made from special sheets of rubber material fastened together with seam tape and fixed with a bonding adhesive to the deck.
