Roofing paper is an essential material used for installing and repairing roofs. It is sometimes known as "roofing felt," "tar paper," "roofing underlayment," or "roofing membrane." Other fine synonyms for roofing paper may include asphalt felt, roof felt, roofing fabric, or roof membrane. These synonyms provide various options for contractors to choose from. For instance, roofing fabric may be a suitable choice for those looking for extra longevity, while tar paper tends to work best as an underlayment. Regardless of the synonym used, all roofing papers are designed to provide insulation, weather protection, and leak barriers for a long-lasting roof.
