roofing paper

Encyclopedia Article


Also known as roofing felt or tar paper, roofing paper is made of either heavy-duty paper or fiberglass mat that is soaked in tar or asphalt to produce a waterproof material. This material is used as an insulating layer in roof construction, and is normally laid in sheets over the wooden sheathing of the house and under the exterior shingles.
