Orange County NY Roofing: Article About Attic Ventilation
Having the right amount of ventilation in your attic makes the home more energy efficient and helps prevents issues such as ice dams and mold. There are also many shingle manufactures that require balanced insulation in the attic to validate their warranties. It is difficult for a homeowner to determine if they have adequate ventilation, which is why Orange County NY roofing professionals perform low-cost inspections to determine the type of ventilation your roof requires.
Part of the ventilation system of the home is located at the soffit area, where a continuous intake of fresh, cool air pushes hot, moist air out of the roof ventilators located near the peak of the roof. Maintaining proper airflow in the attic contributes to the longevity of your roof by ensuring that the proper temperature in your attic is maintained, therefore inhibiting the growth of mold, which can lead to wood decay and rot.
When an experienced roofer is contracted to install and repair the ventilation system of your home, they ensure that all work is performed according to manufacturer standards. They also know what is required with respect to roofing and building envelope issues, which can solve many ventilation problems.
Proper roof ventilation systems should have baffles installed at the eaves area under the sheeting or roof boards.

When they are properly in place, they allow airflow induction at the eaves area of the roof, without being impeded by insulation. If insulation blocks the flow of air in the attic, it can lead to moisture build-up, which can cause mold to grow and eventually rot the wood supporting structures of the roof.
Homes that are older were often built with roof rafters pocketed between the brickwork of the home. If your home was designed in this way, it may be necessary to remove bricks located between the rafter spaces to allow air to flow into the attic. Homes built in this manner are identifiable by having very short under-hangs as well as tongue and grooved wooden soffits. Once the bricks are removed, then new, continuously vented aluminum soffit panels can be installed on the underhang. The new panels will provide your home with a lower-maintenance exterior. Only an experienced roofer should perform this work.
If your roof is fitted solely with a ventilator or small gable-end vents, adding soffit vents will greatly increase the air flow in your attic. Evacuating warm, moist air that escapes from the living spaces below the attic ensures that mold growth is inhibited and will help to prevent the formation of ice dams on the roof. Soffit vents allow outside air to enter the attic at the underside of the eaves, the lowest point of the roof. The new air in the attic helps push warm, stagnant or moist air out through the ventilators.
