The benefits of roof ventilation cannot be trivialised, for the benefits of roof ventilation go far beyond keeping your home cooler in summer. Yes, that’s right, the benefits for roof ventilation are many – by drying the roofspace from condensation and/or humidity moisture you will be alleviating all the follow on problems.
Moisture in the roof cavity can contribute to or exacerbate existing allergy problems: Sick Building Syndrome due to bacteria, mould, mildew – mould fungus will grow in moist poorly ventilated spaces and can travel through air in minute spoor particles triggering allergic responses, toxic mould can be fatal (so the last thing you need are ceiling vents allowing an opening to the roofspace).
Then there is the structural damage that can be caused from not having an effective ventilation system to dry out the roofspace – insulation can trap moisture reducing the R value with the trapped moisture resulting in ceiling damage, creating the perfect environment for termites to thrive and further structural damage dry rot to timber and thermal creep (see BLOG on this site “Thermal Creep” and “Warning! Read Before You Design Your Next Housing Project”).
With roof ventilation you can have too much or not enough the wrong kind or two different kinds that do not work well together.
So when you are looking for the right amount of roof ventilation, the right kind to effectively ventilate your roofspace and the one single system that has inlets and outlets within an integral system – look no further than Universal Tile Ventilators for tiled roofs and Smoothline ventilators for corrugated colourbond roofing keeping you cool in summer and dry from condensation and/or humidity moisture 24/7 all year round.
