ROOF VENTILATION
Trapped roof heat is one of the biggest challenges of a building’s cooling system
Attics are hot places in the warm seasons. If you’ve never been in a hot attic space, it’s easily comparable to a sauna – it’s unpleasant, and through radiance against your ceilings, creates a continuous sponging effect on your air conditioner’s cooling benefits. As hot air rises, having a warm ceiling only further intensifies the extra warmth in the top of rooms, and even more in a two-story home.
There are many types of vents and cooling devices
However, a simple system of vents or fans always does the trick, reducing ambient heat in the building by letting the stifling attic heat escape. The cost of any ventilation device is easily negated by the improvement in cooling.
Other issues with poor ventilation
Besides losing precious cool air in the summer months, there are a few other issues that arise from a poorly vented top.
Dead air: Houses can ‘breath’ in a subtle way, and any air pulled in from attic is truly dead air – it’s a quality of air that no one wants to breath on a daily basis.
Extra Moisture: warmth and humidity create ambient moisture that also effects the materials that air is in constant contact with.
Dry rotting sheathing: increased heat in the attic means the materials are being exposed to extra heat as well – this can affect the material basis, and age it pre-maturely.
Ice Damns: the colder months can also place a negative effect on roofing with poor vents.
So, it may seem surprising but poor ventilation can lead to loses including the need for emergency leak roof repair.
SOME VENT TYPES: Ridge Vents, Off Ridge Vents, Powered Attic Fans, Box Vents, Roof Turbines, Solar Powered Vents, Soffit Vents, Gable Vents are a few of the common types that will save your home and attic from stifling conditions.
