Roof Underlayment Supplier Los Angeles

Roof underlayment sits beneath the visible roof covering, making it an important part of the overall roofing system. We supply roof underlayment for contractors, builders, and property owners working on roofing projects throughout Los Angeles and Southern California, with products suited to asphalt shingle, metal roofing, and other applications.

Roof Underlayment We Supply

The underlayment you need depends on the roofing system, product specifications, and project requirements. We carry several types and can check current availability based on what you’re looking for.

Synthetic Roofing Underlayment

Synthetic underlayment provides a lightweight, water-resistant layer beneath the roof covering. It's commonly used with asphalt shingles and other roofing systems where a durable underlayment is specified.

Rubberized Asphalt Underlayment

Rubberized asphalt underlayment combines asphalt with rubber polymers to create a flexible, water-resistant material. Depending on the product, it may be used in areas that require additional protection from moisture.

Self-Adhered Underlayment

Self-adhered underlayment has an adhesive backing that allows the material to bond directly to the roof deck. Specific products can be used in areas where additional water protection is required, subject to the roofing system and manufacturer requirements.

Asphalt-Saturated Felt

Asphalt-saturated felt, sometimes referred to as roofing felt or felt paper, remains an option for certain roofing applications.

Ice & Water Protection

Ice and water underlayment provides additional protection in areas vulnerable to water intrusion, such as valleys, eaves, roof penetrations, and other detail areas.

Roof Underlayment Brands We Carry

Available underlayment products and manufacturers vary by current inventory. If you have a specific product, brand, thickness, or specification in mind, our team can check what’s available.
