Preheat your oven to 350F. Line a jelly roll (15x10) pan with parchment paper. Be sure to leave an overhang on the sides in order to make it easier to remove from the pan.
In a large bowl combine the flour, baking soda, pumpkin spice, and salt. Whisk until free of lumps.
In a medium bowl combine the sugar, eggs, vanilla, and pumpkin puree until smooth
Fold the dry ingredients into the wet ingredients until just combined.
Pour the batter into the prepared pan and spread evenly.
Bake the cake for 15 minutes or until a toothpick inserted into the center comes out clean.
Remove from oven and immediately lift the parchment paper out of the pan and onto a flat surface.
While the cake is still hot, begin to slowly roll the cake, starting at one of the short ends. Roll the cake and parchment all the way up and allow it to cool completely like this.
While the cake is cooling prepare your frosting.
