The attic: It is a neglected storage space, but the ventilation up there affects comfort in your home, energy bills and how long that roof lasts. Your roof and attic requires the ability to breathe as well, think of it like the respiratory system for your home.
Hot air rises naturally. Inadequate ventilation allows the summer heat to become trapped in your attic, causing temperatures inside to soar above 150 degrees Fahrenheit – forcing your air conditioning system into overdrive. Consequently, you pay more for less efficiency from A/C usage or fans.
Moisture becomes your enemy. It is evident that poor ventilation can cause a build-up of damp air which facilitates perfect mould breeding, wood rot and insulation damage. Winter condensation can freeze and unfreeze countless times, speeding the devastation of an already decaying frame.

Proper airflow requires balance. Proper ventilation requires intake vents (typically soffit vents along the roof edge) and exhaust vents (ridge or peak of roof, to allow air flow across attic space). This means the hot, moist air will naturally want to leave your house and cool air will be sucked in without you even having to think about it.
Ventilation is like kryptonite for ice dams. Ice dams in winter happen when the trapped heat unevenly melts snow. Roofing insulation combined with the right type of ventilation keeps your roof consistently cold and prevents those expensive icicles from forming which later damage gutters and cause leaks.
Your roof materials last longer. Moisture thermal stress on tiles, felt and timber components is reduced because better ventilation leads to a much cooler roof which stays intact for many more years.
Get your venting system professionally inspected for better efficiency even heat distribution. Do not overlook the importance of investing in good roof ventilation, as it will come back to you in terms of lower energy costs and a longer-lasting (low maintenance) perfect roofing option.
Why well insulated homes need roof vents
Modern homes are built to hold on to heat, with insulated cavities, double glazing and thick loft insulation. The catch is that warm, moist air rises and has nowhere to go but the roof. In winter, with doors shut and the heating on, that air meets the cold, unheated loft and condenses on the joists and floor.
Left unchecked, that damp can rot woodwork, damage joists and fixtures, spoil insulation and encourage mould, which is unsightly and bad for breathing. The effects can spread downstairs too, with peeling wallpaper and bubbling plaster and paint.
The answer is to let some warm air escape and draw cooler air in, which evens out the temperature in the roof space. Vents along the ridge give warm air a way out, while vents in the eaves bring fresh air in from outside, creating a steady flow through the loft. Treat ventilation as just as important as insulation, rather than an afterthought.
