Asphalt Felt Paper For Roofing Shingle Underlayment

 

Introduction

Asphalt felt paper has been the go-to substrate for roof shingles for more than a century, and it's still quite popular because of how well it works and how affordable it is. 

Traditionally, asphalt felt underlayment has been 36inch wide, 15lb or 30lb felt impregnated paper, and it is used as a weather resistant layer over the entire roof surface. It keeps sheathing dry until shingles are installed, serves as a backup layer when water gets under shingles or flashing, and prolongs shingle life by separating sheathing and shingles. (Without underlayment, shingle asphalt can leech into wood sheathing, or resins in sheathing can degrade the shingle.) 

Heavy duty, 30lb felt paper is often specified in high-wear, high-water areas such as eaves and valleys. A standard roll of 3-ft wide, 15lb felt paper covers roughly 432 sq.ft, the same size roll of 3-ft wide, 30lb paper covers only 216 sq.ft because it's roughly twice as thick.
