Benefits of Ridge Ventilation

Air movement is the key to efficient ventilation to help eliminate damaging conditions in your attic.  Ridge vents provide constant air flow along the entire underside of the roof to help remove heat and moisture.

Attic and roof temperatures can soar as high as 160 degrees in the summer.  This over heated air can damage roof structures and shingles, as well as increase cooling costs in the home.  Ridge ventilation can create an air flow to remove this over heated air. 

Excess moisture can be as damaging as too much heat.  In today's tightly constructed homes, moisture can accumulate in the attic causing mold, mildew and wood rot.  Ridge vent systems work year round to ventilate the attic.

Heat and moisture combine to damage shingles, trusses, rafters, roof deck and painted surfaces.  Ridge ventilation can help extend the the life of shingles and the roof structure.

Research has shown that the best way to ventilate an attic is with a system that provides continuous airflow along the entire underside of the roofing sheathing.  Achieving this desired airflow requires a balanced system of ventilation along the soffit or underweaves of the roof and exhaust ventilation at the ridge.

The main purpose of roof ventilation is to have temperatures on the outside and inside of roof materials as close as possible. This also includes the reduction of moisture buildup.

Most houses have static ventilation devices that include ridge vent , gable openings, and small static vents.  These upper roof vents combined with adequate soffit vents provide airflow during evening and non-sun conditions.

Power ventilation (use of motorized fan systems) during the heat part of the day  reduces the pressure (heat) buildup and in fact , creates a slight negative pressure that allows soffit vents to work effectively.

The Sunvent reduces high temperatures in an attic or building, helping to remove hot air which transmits heat directly to the living space.

 Air-conditioning loads can be reduced up top 30% . Moist air can be eliminated from vented in house air ducts.  A combination of high efficiency motor and specially designed 5-blade fan provides airflow that is so quiet that it is difficult to hear.  There is no motor noise as in conventional A.C. models and no large bearing assemblies as in turbine models.
