Once you get the hang of installing roofing felt over the hips, it's not much more involved than installing the felt on a gable roof. the basic idea is to install the asphalt-treated felt in such a manner that the roof will shed water.. Roofing felt or similar is a secondary protection membrane, should the shingles leak, and isolates the shingles from the sheathing. it is required in some areas, but always a good idea.. Tar paper has been time-tested as a weather barrier. normally used on roofs, tar paper makes a great barrier for the exterior walls of your housing, building or shed. tar paper keeps the wood beneath it dry..
