For decades, Gerard roofs have been acclaimed around the world for their innovative design, robust quality, and wide choice of finishes and accessories offered.

Unique Features


The interlocking system

Gerard steel roof panels lock together to form a singular weathertight unit. Furthermore, the design eliminates any gaps where flying embers might enter.

Horizontal fastening

Unlike long-run and heavy tile roofs, Gerard steel panel roofs are fastened at right angles to the wind’s lifting forces – holding on tight even in Category 3 hurricanes.

Up to seven protective coatings

A Gerard roof has up to seven different coatings applied for long lasting protection. The final layers are applied after the panels are formed to avoid surface cracking.

A lighter load

Where a concrete or clay tile roof could weigh 10 tonnes or more, a Gerard roof can weigh just one tenth of that, which is particularly reassuring in an earthquake.

Textured v Smooth


With a crisp look to accentuate the roof pattern and details, Gerard’s smooth finish panels look like coloured steel but are much more durable.


Made with natural stone chips, our textured finish gives your roof a stronger, more substantial look, and added protection from the elements.

Gerard Profiles


Inspired by the smooth stone slate roofs typical of alpine regions, Aspen gives a sleek, understated look of modern sophistication.


The smooth, linear look of Welsh slate with slightly rustic detailing. A simple profile that works well with both contemporary and traditional architecture.


A geometric profile with bold, strong-looking shapes and angles. Often used on homes where the roof is an architectural feature in its own right.


Irregular grooves give this profile a recurring yet organic pattern that works on a wide variety of homes. Supremely versatile, and immensely popular.


The traditional scalloped style of a terracotta tile roof. Often seen on traditional brick homes, but equally appropriate above plaster or weatherboards.


Balanced arches and flats create a perfectly elegant, classical looking roof. This timeless profile makes a strong statement, especially on steeply pitched roofs.


A sleek, linear look that sits low and tight to complement popular postmodern house designs. Perfect for clean, simple architecture with a modern bias.


The distinctive vertical ridge adds refinement, giving the roof a timeless character. Well known for the simplicity and uniformity it brings to a roof.

Roof Trims

Roof trims are an important part of your roof, both for weather-
proofing and appearance. We make four types of trim, which are
fully compatible with our range of pressed steel tiles:

Angle Trim

Barrel Trim

Long Angle Trim


Gerard Accessories

To complete the look of your roof, our accessories are fully
integrated and designed to match your chosen style.


Gerard vents are finished with the same coatings as your roof, so they’ll match it perfectly. Plus they can be installed by the roofer – no need for a plumber to be working up top.

Gerard free-flow port

A low-profile port designed for extraction systems from kitchens, bathrooms and laundries. And with a large free vent area, it’s also ideal for airflow and heat circulation in roof cavities.

Gerard Sanitary Port

Primarily intended to vent sewage systems, this port can also be used for general air/moisture extraction from kitchens, bathrooms and laundries.


Solar Brackets




The warm roof solution for pitched roofs, Gerard Thermacore™ insulation actually sits above the rafters – therefore outside the building structure. This creates a continuous barrier that thoroughly blocks thermal leakage and moves the dew point to the outside which eliminates a major cause of condensation. Ideal for new and existing builds, both the Gerard Thermacore™ and your Gerard roof are installed at the same time by a Gerard Distributor.

Cleaning Product

Over time, lichen and moss will grow on most outdoor surfaces – including your roof. Left unchecked, it damages the surface coating of your roof, creating ‘moisture traps’ that can cause corrosion. Using Gerard Roof Refresh will remove the growth and help prevent future problems

Prevent growth before it happens

Gerard Roof Refresh is a powerful cleaning agent that targets not only the lichen, moss and algae, but also the spores that lead to it. We recommend treating the roof every three to five years, or sooner if signs of growth are visible (this is also required to maintain the warranty on your roof). You can either spray the roof yourself, or arrange a commercial contractor who specialises in this type of work.
