The present invention relates to a novel rooftop shading system for recreational vehicles (RVs) and a method of installing the same. The shading system comprises a sheet of material generally sized to cover the roof of an RV. The sheet is supported over the roof with support rods which extend across the width of the roof and maintain a curved shape of the sheet. The sheet is secured to the RV by two strap systems which extend from the front end and rear end of the sheet. This system allows the sheet to be secured to and elevated from the roof of the RV providing space and producing shade to the rooftop of the trailer body or RV.
