Rainwater from the roof could harm the vegetation around the house and increase the risk of moisture build-up at the foundations. This could damage your materials and form mold and efflorescence. In fact, the absence of a gutter is a very likely cause of water infiltration through the walls.

Recovered by drains or gutters, the water accumulated on the roof will be removed from the foundations. This is necessary if you want to prevent water from collecting near the foundation walls or overloading your French drain.

What material to choose for its gutters?

  • Several choices of gutters are available on the market, with varying impacts on the environment.
  • PVC (vinyl): the most affordable, but not recommended, because it degrades on contact with ultraviolet (UV) rays, releasing particles harmful to health and is very sensitive to temperature variations.
  • Aluminum: light, lifespan of about ten years, recyclable.
    Copper: more expensive, but generally last as long as the house. It is necessary to entrust its installation to a contractor (welding).
