Ventilation, natural light and solar power

Along with all the essential trims, fixings, flashings and battening, Gerard offers optional extras that are fully integrated and designed to match or complement the aesthetics of the roof where possible.

Gerard Vents

Vents that perfectly match your roof

Manufactured from HIPS (High Impact Poly Styrene) and finished with Gerard’s coatings, the vents are not just fit for purpose they precisely match the colour and finish of any Gerard roof.

Keep things simple and save on plumbing

Your Gerard Certified Roofer can install the vents as part of the roof; your plumber need only connect up on the inside, so there’s no need for him to be working up top with flashings and pipes that could compromise weather tightness.

Gerard Free-flow Port

A low-profile vent intended to cap off general extraction systems from kitchens, bathrooms and laundries; with a free vent area of 20,000mm2 it’s also ideal for airflow and heat circulation in roof cavities. The unit comes with a 100-150mm stepped adaptor that fits most ducting.

Gerard skylights

Gerard Skylights can bring light and air into any room. Their advanced no-flashing installation system reduces risks of leaks. Gerard Skylights are available with a transparent or opaque dome. You can also choose between vented or non-vented options Product features weather-safe vents that remain permanently open.

Gerard solar brackets

Secure solar panels without roof penetrations

The Gerard Roofs system ensures that solar panels and rails are securely fixed and supported by a complete substructure without penetrating the surface of the roof – roof penetrations should always be avoided as they can lead to leaks.

Gerard Roofs solar brackets are designed to fix any conventional type of solar panel to a Gerard roof, regardless of size and configuration.

Ideally, installing solar panels should be carried out during a complete roof installation. However, the system does allow for solar panels to be successfully retrofitted, under certain circumstances, provided the work is carried out by Gerard
certified installers using approved methods. Contact us for details.
