Roof leaks found and fixed properly
A roof leak rarely shows up where the problem is. Water can enter at a cracked tile, a lifted flashing or a blocked valley, run along battens and rafters, and appear as a stain on a ceiling several metres away. Patch the stain and the leak stays. Guess at the roof and you pay twice.
We trace leaks methodically from inside the roof space and on the roof, repair the actual entry point, and then fix the damage the leak caused: wet insulation, stained or sagging plasterboard, swollen cornices and any water-affected light fittings. Because we're builders and electricians, the whole job is done by one team.

Water coming through now?
Put a bucket under it, move valuables, and if water is near light fittings, switch off that circuit or the main switch if it's safe. Then call our 24/7 line and we'll tarp the roof.

Roof leaks and electrical safety
Water in the roof space often reaches downlights, ceiling fans and cable joins. If you have water coming through near light fittings or power points, treat it as an electrical hazard. Our electricians check and make safe affected circuits as part of the roof repair. See electrical services.
Strata and commercial roofs
Strata and commercial roofs bring their own problems: box gutters that overflow into units, flat membrane roofs, roof plant penetrations and parapet flashings. We repair and maintain these roofs for strata managers and commercial owners. See strata maintenance.
