A roof overhang, also called an overhead roof, extends the roof, on a terrace or front door, while protecting the walls of the house. Explanations.

What is a roof overhang?

The roof overhang allows to extend the roof and thus, to protect the facades of the house and the windows of bad weather but also of the sun. It has great aesthetic quality but is often overlooked for legal issues. Indeed, this advance of the roof can encroach on the ground of the neighboring property. In the past, many homes have been cut off from their eaves in the name of the invasion of private property.

The overhang can be set up for both a sloping roof and a flat roof. In the case of a flat roof, the overhang is obviously horizontal and allows rainwater to flow easier. In the case of sloping roofs, there are several forms of roof projection: horizontal or sloping, in the extension of the roof.
The overhangs can be self-supporting or be the subject of a distinct supporting structure, according to the vision of the architect, according to the shape of the roof but especially according to the final covering of the overflow. For example, a brick or stone overhang requires a heavy load-bearing structure unlike wood or pvc, which is lighter.

What are the advantages of a roof overhang?

Although not common, a roof overhang offers many advantages:

  • The covered space obtained can be used to protect an entrance or a terrace,
  • The gutters being fixed to the overhangs, the facades are spared in case of leakage of water or breakage,
  • The parts of the windows below the overhangs benefit from the shade of these in summer and the light of the sun low in winter,
  • The choice of trim finish is wide: wood, pvc, stone, metal, etc.,
  • The visual effect is aesthetic: the house is embellished. The overhangs, which can be very worked, allow to put mood lights and to put the house more value.

The overflow roof has only one defect: the price since it involves more work at the level of the roof.
