Resolving Roof Ventilation Issues


We recently have done on some repair work on an older home where we resolved the root of some moisture and roof ventilation issues that lead to air contamination and discomfort for the owners.


Underlying these problems were:


  • Rotting Insulation

  • Deteriorating Battens

  • Worn Pointing

  • Cracked tiles allowing water and moisture through


AIR CONTAMINATION


In this case and others, air contamination can be due to rotting insulation that releases dust particles into the air, causing them to circulate within the house which is not ideal for residents.


This rotting can be due to insulation deteriorating over time, and the process is accelerated by water and moisture exposure from cracks and damage to the outer tiles or metal roofing. The build-up of dust particles from the rotting insulation can be vacuumed away and new insulation installed to prevent further air contamination.


ROOF VENTILATION DEVICES


An additional installation that will help the air quality and ventilation within a home are whirlybird vents.


Whirlybirds are a roof ventilation device that extract heat and moisture from the inside of a home, leaving it cooler and less prone to humidity and mould growth. They are great investments for a home and help maintain quality air conditions within your house.


ROOF BATTENS ROTTING


During the roof inspection in this case, it was also found that there were sunken tiles due to rotten battens underneath that were giving way.


Rotten battens can occur from exposure to excess moisture and water invading from cracked or porous tiles above, or from pests such as termites. Sunken tiles such as these need to be lifted, the rotting battens replaced, and new tiles installed. Any surrounding tiles that are chipped or cracked should also be replaced to maintain the structural integrity of your roof.


In this case there were also damaged tiles near the valleys and under ridge caps, which upon fixing needed repointing. By replacing these damaged tiles, the roof is regaining its integrity and watertightness, preventing moisture from seeping in.


RESTORING AIR QUALITY


Hence, there can be quite a few issues contributing to poor roof ventilation and inadequate air quality within a home.


Particularly in older homes, these can include issues such as cracked or porous tiles that allow moisture to seep through the roof, leading to further damage to battens and roof insulation and promoting mould growth from the increased humidity.

Rotting battens can further contribute to damaged tiles by causing them to sink, and should be addressed as soon as possible. Whereas deteriorating insulation can lead to air contamination by giving off dust particles which can be breathed in by residents, causing discomfort.


By laying in new roof insulation and roof ventilation devices such as whirlybirds, air quality can be restored.
