Common reasons

  • The repair treated the symptom, not the source
  • Several entry points exist at once
  • The problem only appears under certain conditions (wind-driven rain, snowmelt)
  • A joint between two materials was overlooked

What helps the diagnosis

  • A history: dates, weather, past repairs
  • Photos of each episode
  • Access to the exterior of the affected area

Our approach

Entreprise SGB carries out the investigation itself before proposing corrective work. This information is used to plan the work; it does not replace an expert report requested by an insurer or in a dispute.

Official sources
