Disclosed is a roof spoiler that effectively disrupts the attached flow of wind on a roof surface. Preferably, the spoiler is specially designed for installation with a gutter mounted on the roof fascia or along the leading edge of the roof. This spoiler utilizes a hinged design to move between two operating positions. The first position is a stowed position, whereby the spoiler extends beyond the gutter and is designed to be nearly invisible to passersby. In the stowed position, a portion of the spoiler covers the outer edge of the gutter (if present). A second portion of the spoiler may extend outward from the gutter. The second position is a deployed position, wherein a barrier is projected vertically, or substantially vertically, so as to disrupt the flow of air over the roof surface. In one embodiment, the spoiler rests upon the roof covering when in the deployed position. In another embodiment, the spoiler rests near or against the gutter or holding bracket. In one embodiment, a bracketing system, or support structure, is placed around an existing gutter. The roof spoiler is then pivotally attached to this support structure. In another embodiment, the support structure attaches directly to the gutter.
