Flat roof structure

Flat Roofs presented by Pelasgos Homes

Flat roofs represent the most efficient use of urban space, offering architectural freedom, control of the downflow of the water to the drainage system as well as energy savings.
Roofs of a very low slope are usually selected for one or more reasons; aesthetic design, provision of a promenade roof /deck and ease of covering for structures of complex plans.

We design our roof structure according to the architectural drawings of our Customers!

  1. Metal structural trusses are positioned every 40-150 cm, based on the engineering drawings.
  2. A galvanized trapezoidal profile which is being used in the construction of large spanning composite decks is installed on top of the metal trusses.
