Roofing Underlayment

Roofing underlayment is a water-resistive barrier material installed above the roof sheathing and below the roofing material. The underlayment serves as an added layer of protection from severe weather. The type of underlayment may vary depending on which type of roofing material selected. If you select integrated sheathing (see section 04, Rough Framing), underlayment may not be required.

 

Select type of underlayment:

__ asphalt saturated felt (water resistive)

__ synthetic underlayment (water resistive)

__ rubberized asphalt underlayment (waterproof)
