Factory Roofing & Sawtooth Roof Repairs

Sawtooth and monitor roofs

Many older Sydney factories have sawtooth roofs -- rows of angled glazed faces designed to flood the floor with even north light. They're brilliant for daylighting and awful for leaks once the glazing putty, flashings and gutters between each tooth start to fail. Water gets in at the glazing bars, the internal valley gutters between teeth silt up, and the whole system needs careful staged restoration rather than a quick patch.

We re-glaze, renew the flashings at each ridge and valley, and clear or upgrade the between-tooth gutters. Where original glazing is beyond saving we replace it with modern glazing or polycarbonate that keeps the daylight without the constant leaks.

Process heat, steam and corrosive exhaust

A factory roof takes punishment from the inside. Rising process heat and steam condense on the underside of the sheeting and rot it from below, and exhaust from paint, food, chemical or metal-working processes eats coatings and corrodes fasteners faster than weather alone ever would. We assess the sheeting from underneath as well as on top, upgrade ventilation to shift heat and moisture, and specify materials suited to the exhaust your process produces.

Working around live production

Stopping a production line is expensive, so we plan around it. We coordinate roof access to avoid working directly above running machinery or hazardous processes, schedule noisy work for shift changes or maintenance windows, and manage debris so nothing contaminates your product or plant below. Where a section genuinely must be shut, we scope it tightly so the downtime is as short as possible.
