Brisbane Storm Season Roof Inspection Checklist (2026 Guide)
Between November and April, South-East Queensland regularly experiences severe supercell storms featuring 90 km/h+ wind gusts, marble-to-golf-ball hail, and torrential rainfall. Here is how to inspect your roof and prevent catastrophic ceiling collapses before the next storm hits.
The 7-Point Pre-Storm Roof Checklist
Review these key checkpoints or book our certified tradesman inspection:
Cracked Ridge Cap Mortar Bedding
Old cement mortar cracks as your house settles. Wind-driven rain forces water under caps straight into ceiling insulation.
Chipped, Cracked, or Slid Tiles
Hail impact and foot traffic cause hairline fractures that split wide open under storm downpours.
Blocked or Rusted Valley Irons
Valleys channel thousands of litres of water during storms. Pin-hole rust causes concealed internal leaks.
Heavy Moss & Lichen Encrustation
Lichen dams rainwater between tiles, backing up moisture over the top laps into your timber roof trusses.
Lead Flashing Around Chimneys & Skylights
Check for lifted or torn flashing edges that allow water penetration along parapet walls and penetrations.
Why Traditional Cement Mortar Fails in Queensland
In older Brisbane homes across Logan, Chermside, and Sunnybank, ridge caps were set in standard 3:1 sand-and-cement mortar. Because concrete is rigid and brittle, natural thermal expansion from 38°C sunny days followed by sudden cold 20°C storm cells causes the mortar to snap and fracture.
At Pro Paint & Property Care, we replace old, fractured mortar with flexible acrylic polymer pointing compound (like Selley's Point Works). This compound expands and contracts with the roof structure while bonding tiles with tenacious adhesion, providing wind-shear resistance up to Category 3 cyclone wind forces.
