Flashings

Flashings are the hidden work that makes a roof last — every penetration, parapet, valley, chimney, wall abutment and change of pitch needs a properly folded, correctly lapped flashing or it will leak. ONTRA hand-folds flashings on site from Colorbond, zinc, aluminium, lead and copper, so every profile is tailored to the exact substrate rather than forced from a generic off-the-shelf section. It is slow, careful, expensive work — and it is why our roofs stay dry decades after the last screw goes in.

Every flashings project at ONTRA follows the same process: site inspection, written scope, fixed-price quote, fabricated and installed by our in-house team, and signed off with a final photo report.
