Roof Ventilation

Problems associated with heat and moisture in the roof can be avoided by the installation of adequate ventilation systems.

At Jims Roofing,we have found that whirly birds provide a cheap solution to removing excessive heat from the roof in summer and damp air in winter, as such we recommend and install Ampelite products and systems for roof ventilation as well as fibreglass roofing and laserlite roofing

Cools your roof space - Cools your Home

How it works - How it Saves
Ampelair turbo vents exhaust the very hot air that becomes trapped in the space between the ceiling and roof. This prevents heat radiation into rooms.
A well ventilated home is protected from problems associated with moisture condensation and temperatures that can soar to a blistering 60ºC. In hot humid localities, mould, mildew, dry rot, and damp insulation (which becomes inefficient), is frequently found where proper ventilation is not provided.
Normal insulation is not enough to prevent heat radiation into your home. With effective roof space ventilation less heat is radiated into your rooms, and air conditioners and fans can cope more easily. Power costs are reduced.

Winter ventilation is important too!

Removes damp air - Saves on Heating
Moisture laden air from inside the home, and outside air, can condense and cause dampness. Good ventilation prevents damage to ceilings and roof timbers, formation of mildew etc. Shaded areas of your home particularly benefit.
Ceiling insulation loses it effectiveness when it becomes wet, and as a result, increases the need for heating to compensate for heat loss. Damp conditions can also cause ceilings to become mildewed. Proper ventilation of the roof space overcomes these problems and helps lower heating costs. Bathrooms and kitchen ventilation is also improved.

We recommend installation of 2 under eave vents per AA300 ventilator to ensure correct operation.
