Get to Know JSIU.roofing

At JSIU Roofing, we don’t just clean black mould — we investigate the root cause, document it clearly, and help Melbourne homeowners hold volume builders and insurers accountable when poor workmanship or failed waterproofing is to blame.

Whether you're dealing with a leaking roof, poor ventilation, or suspected building defect, our expert inspection reports are designed to give you leverage in disputes, insurance claims, or builder warranty cases.

• Roof & Ceiling Ventilation Failures – Solar vents, whirlybirds, airflow design
   
• Hidden Leaks & Moisture Traps – Flashings, valleys, gutters, and tile faults
   
• Cavity & Attic Observations – Signs of trapped moisture and long-term water damage
   
• Structural & Insulation Issues – Sagging plaster, rotting timber, insulation collapse
   
• Black Mould Source Identification – Not just where, but why it’s forming
   
• Before & After Photo Reports – With optional video footage for proof
