Abstract: A system for protecting building structures such as mobile homes, trailers, sheds, and hangars from high wind conditions comprising a rigid plate-like member externally attached in the middle and across the width of the roof of the building structure. The plate-like member is raised at the center thereby forming an arch-type structure. Four rigid tubes coming from four corners of the roof of the building structure join above the center of the plate-like member. The tubes are held together between two disks, which are tightened together by a bolt and nut assembly. A tent-like cover with a plurality of eyelets is anchored to the ground surrounding the building structure. The canopy means is independent and separate from the building structure it covers, and extends downwardly and outwardly from above the roof of the building structure at an angle in order to deflect the wind and avoid pressure build-up.
