Roofing underlayment is a barrier material that is installed directly onto a roof deck. Underlayment is either water-resistant or waterproof. Underlayment is an extra layer of protection in case of severe weather. It’s applied over the roof deck and below all other roofing materials.
Three main type of roofing underlayment exist:
- Asphalt-saturated felt (water-resistant)
- Synthetic underlayment (water-resistant)
- Rubberized underlayment (waterproof)
Of course, new technology expanded on these three types. For example, check out elastomeric styrene-butadiene-styrene (SBS) polymers (synthetic rubber) used for underlayments or SBS-modified asphalt membranes.
Endureed’s Underlayment Suggestions
Endureed’s installation specifications call for installation of self-adhering, waterproofing underlayment on top of any roof decking. Self-adhering membranes automatically seal around nails and other penetrations. They do well if exposed to sunlight. Plus, they stick to almost any material.
Of course, you’ll comply with any low-temperature installation restrictions from the manufacturer. You’ll install lapped in directions to shed water with sides not less than 3.5 inches. Plus, lap ends not less than 6 inches staggered with 24 inches between courses.
