A 17-year-old Carrum Downs boy has been charged after he allegedly fired a missile into the roof of a Melbourne home.

The boy and and a 16-year-old Seaford girl were arrested on Wednesday morning, almost three months after the explosion at Carrum Downs.

The boy was charged with six counts of explosive-related offences over the incident, which allegedly occurred on August 28.

He was bailed to appear at the children's court at a later date.

The girl has been released pending further enquiries.

Detectives said the device was ignited at a reserve on Hillview Drive about 5pm on August 28 and rocketed into the sky before it crashed into the roof of a home about 150 metres away.

The missile caused extensive damage to the roof as well as inside the property.

Two people who were home at the time were not physically injured.
