Steel roofing
Colorbond metal re-roofing
Sheet steel suits Sydney conditions: it sheds heavy rain quickly, carries a fraction of tile's dead weight, and modern coating systems handle coastal exposure when the grade is matched to the site. Replacing an old metal roof means new sheets, screws, flashings and insulation blanket in one program.
Scope
What this covers
Removal of corroded or fatigued sheeting and old fixings
New Colorbond roofing fixed to the manufacturer's screw pattern
Anti-condensation blanket or membrane laid beneath the sheets
Ridge, barge and apron flashings folded to suit the profile
Matching gutters and downpipes where the scope includes them
Timing
When it's needed
Rust blooming along laps and fastener lines, sheets lifting in wind, and ceiling stains tracking under fixings signal a covering past its useful life. Coastal properties often step up to a marine-grade coating at replacement: a material decision to settle before ordering, not after.
Stay off the roof. Aged tiles crack underfoot, brittle sheeting can fail without warning, and unprotected edges cause serious falls. Photograph from the ground or a window and leave the climbing to crews with edge protection and the right equipment.
Quote variables
What shapes the scope
Sheet profile and coating grade for the distance from salt water
Purlin or batten condition revealed once old sheeting comes off
Penetrations (flues, skylights, solar mounts) each needing new flashing
Length of custom-folded flashings and cappings on the design
Roofing in NSW is licensed work: roof tiling and roof plumbing are distinct specialist categories, and residential building contracts above the statutory threshold require a contractor licence, with home building compensation cover applying to larger jobs. Check any contractor's licence against the NSW Fair Trading public register before signing anything.
