Felt roofing material is not like the felt sets used in the children's Sabbath School classes. Rather, "felt roofing" is just another name for tar paper. Before installing the felt roofing, you should first nail a drip strip to the edges of the roof. Then the felt paper is rolled out over the entire horizontal length of the roof (not top to bottom!) and stapled onto the sheathing. If the felt is not wide enough to cover the roof from the eaves to the peak, you will need another layer. The first layer should be along the eaves, and subsequent layers should overlap previous ones by a couple of inches. If the roof has a ridge vent, do not cover it. The purpose if a ridge vent is to allow heat to escape from the attic. Covering it with tar paper defeats this feature completely. The roof is now ready to shingle.
