ABSTRACT:
A durable shroud is provided for roof ventilators to prevent warm air from escaping through ventilators openings as well as to provide a protective cover for the ventilator in inclement weather. The ventilator is comprised of two hemispherical segments that are coupled to form a complete hemisphere about a roof ventilator. Therefore, weather elements are prevented from contacting the ventilator and heat from within is prevented from escaping through the ventilator openings.
