For the implementation of a framework, many constraints must be taken into account:

  • Plan of the house (form, dimension, orientation …),
  • Mechanical resistance to wind, snow, weight of cover,
  • Slope depending on local traditions, the style of the house, the type of cover chosen,
  • Attic or not,
  • Presence of openings in the roof (skylights, windows, chimneys …),
  • Thickness and type of insulation.
