If your roof has a gravel surfacing and there are some bare spots present, clean the bare spot thoroughly using a broom and a wire brush if necessary. Be sure to remove all loose dirt generated from brushing and sweeping. Blow on the area if need be. Spread a thin layer of asphalt roof cement (mastic) over the bare area about 1/8 inch thick. Gather some loose gravel from other areas of the roof and embed it in the roof cement.
