Fire leaves Grimbergen home uninhabitable after spreading from terrace to roof

Updated 18 August 2026 (CEST)

A serious fire damaged a home in Grimbergen on Tuesday, 18 August, after flames on a terrace spread to the roof, leaving the property uninhabitable, according to an initial report by HLN. The available reporting does not establish the precise time or street, whether anyone was injured, or how the fire started.

The reported sequence — fire on the terrace followed by flames reaching the roof — is the clearest account currently available. HLN described the incident as a major residential fire and reported that the damage made the house unfit for occupation. No accessible statement from the municipality, police, public prosecutor or Fire Service Zone Flemish Brabant West had independently corroborated those details when this article was updated.

That distinction matters in the first hours after a fire. Emergency services can make an immediate operational assessment that occupants cannot safely return, while any formal declaration of uninhabitability follows a separate administrative framework. The Flemish government says a mayor can order evacuation or declare a property uninhabitable when acute safety or health risks require intervention. It also says the municipality or public social-welfare centre can assist residents who must relocate.

The immediate human consequence is therefore displacement, even before investigators and insurers establish the full loss. It remains unknown how many people lived at the address, where they are staying, and whether neighbouring properties sustained smoke, water or structural damage. Belgium Pulse is withholding those details until a named authority or a second news organisation confirms them.

Roof fires demand particular attention because flames can move through dry timber, insulation and concealed cavities. In separate guidance reported by VRT NWS in 2025, Fire Service Zone Kempen warned that roof structures and wall cavities can allow fire to spread rapidly and make suppression difficult. That guidance provides context only; it does not establish the cause of the Grimbergen fire.

The next reliable update should clarify injuries, the exact location, the suspected ignition source and whether a fire expert will examine the property. Officials may also determine whether the house needs structural stabilisation before residents or investigators can enter. Until then, the confirmed news remains limited: fire spread from a terrace to the roof, and the home was reported uninhabitable.
