There is a common misconception that roof ventilation for winter is not needed, this is as further from the truth as pigs may fly. Winter is the season that roof ventilation is an absolute necessity.
You see the objective of effective roof ventilation is to allow the ambient airflow to flow through the roofspace 24/7 all year round to keep the home cool in summer and the roofspace dry from condensation and/or humidity moisture all year round, especially from condensation in the winter.
Some of the reasons why roof ventilation is very important in winter – condensation is the major reason for having roof ventilation in winter, condensation can cause many problems in the roofspace. Due to the moisture from condensation, causes:- saturated ceiling insulation loses its R value and becomes the breeding ground for mould, mildew, termites, the ailments for Sick Building Syndrome, fungal infestations, causing or further exacerbating existing respiratory infections such as asthma, bronchitis, minor and more serious lung infections, sneezing, runny nose, eyes stinging for no reason, etc.
IT COULD BE RAINING IN YOUR ROOF
As well as damage to the building materials in the roof with the saturated insulation causing follow on ceiling damage with further structural damage of timbers dry rot, thermal creep etc. See blogs on this site with relation to these problems, “Thermal Creep”. “Warning! Read Before You Design Your Next Housing Project”.
THE MAIN REASONS FOR CONDENSATION IN THE ROOFSPACE TODAY IS THE OVERUSE OF INSULATION AND THE NEGLECT OF AN EFFICIENT ROOF VENTILATION SYSTEM
It is more likely than not that moisture in the roofspace from condensation in winter applies to colder climates more than warmer ones. However humidity moisture is more likely in the warmer climates at the height of summer.
Areas where condensation can be predominate:- the Dandenongs and the surrounding area of Victoria the best part of Tasmania, Southern NSW including Canberra, inland and the hinterland of NSW, QLD, VIC and TAS and condensation can raise its ugly head almost anywhere in Australia. Honestly we have sent many of our systems to Brisbane to rectify the problems of condensation. So you see no area is safe from the problems of condensation in the roofspace, I guess it’s the luck of the draw.
SO TO GET RID OF THE PROBLEMS OF ROOFSPACE CONDENSATION IN WINTER YOU WILL NEED AN EFFECTIVE ROOF VENTILATION SYSTEM
So with all the ventilators and fans in the market place today how do you choose, when you can have too much roof ventilation or not enough the wrong kind or two different kinds that do not work well together.
