Full Colorbond Re-Roof in Kilsyth

The Project

This one was a full re-roof in Kilsyth — the old roof off, a brand-new Colorbond roof on, and a fair bit of work in between to get it there. It's the kind of job where most of the effort goes into the parts nobody sees from the ground: stripping the old sheets back, checking what's underneath, and detailing every hip, valley and penetration so the finished roof works as a system. Get those right and the roof looks sharp and stays watertight for decades.

The Job

A re-roof on a home with this roofline brings a bit of everything:

• A full strip-back — the old roof had to come off completely rather than being sheeted over, so the structure underneath could be checked before anything new went down
• Multiple hips and valleys — the roof runs across several planes, so every hip line and valley had to be set out square and flashed to carry water cleanly off the roof
• An existing chimney — the chimney had to be flashed and capped properly so water is directed around and past it instead of being sealed over and hoped for
• A skylight and roof penetrations — the skylight and vents needed sheets set out around them so water runs past each opening rather than into it
• A finish that's seen from every angle — with a roof this visible, the ridge, barge and gutter lines all have to sit straight and consistent

What We Did

We stripped the old roof back and went over the structure before laying anything new, then ran the new Colorbond sheets out square across each face. The sheet lines were set out so the runs stay straight and consistent right across the roof — on a roof with this many planes, any drift shows up immediately from above and from the street.

From there it was all in the detail work. The chimney was flashed and capped so water is carried around it and back onto the roof, the skylight was set out and flashed so the sheets shed water past the opening, and each hip, valley and ridge was capped to finish flush and tight. New flashings were run through the job so the roof drains as one system rather than relying on sealant to hold things together.

The Result

The finished roof is exactly what a re-roof should look like — clean, continuous sheet lines, crisp ridge and hip capping, and a chimney, skylight and penetrations that all sit flush and watertight. From above you can see the set-out is straight the whole way across, and from the street the new roof completely lifts the look of the property.

More to the point, it's built to last. New Colorbond sheets resist corrosion for decades, the flashing detail keeps water moving off the roof rather than into it, and the owners are done with the repair-and-patch cycle that comes with a roof at the end of its life. Another re-roof completed, and onto the next one.
