Abstract

This specification covers three classes and three types of asphalt roll roofing in sheet form, in widths agreed upon between the purchaser and the producer/supplier, and composed of asphalt-saturated organic felt coated on both sides with asphalt. Class M and WS rolls are surfaced on the weather (exposed) side with mineral granules, except for any selvage. Class S rolls are surfaced with powdered talc, mica, or other fine mineral matter to prevent sticking. Type classifications (Types II, III, and IV) are grouped based on minimum net mass per unit area of roofing. Roofing shall adhere to physical property requirements such as breaking strength, water permeance and vapor transmission, width, selvage, area, and moisture.
