Tarco Roofing Products

Tarco manufactures roofing underlayments and building-envelope products. The company says it has produced roofing underlayments since 1978 and remains one of North America’s largest independently owned manufacturers in this category.

Product Lines

Tarco’s catalog includes traditional asphalt-saturated felts and base sheets, mineral-surface roll roofing, synthetic underlayments, and self-adhered membranes. Its current product document library lists the products available now and should replace older fixed catalogs.

• EasyLay synthetics: EasyLay UDL 15, EasyLay UDL Basic, and EasyLay UDL 50 are mechanically fastened synthetic underlayments with different weights, exposure limits, and warranty terms.
• Self-adhered membranes: Current listings include MS300, NR600 Ultra, PS200HT, and PS200MU. The suitable roof coverings, temperatures, substrates, and slopes vary by product.
• Traditional products: Tarco continues to list organic felt, base sheets, mineral-surface products, and Quick Roll Shingle Starter.

Older Tarco profiles may refer to SS400, PS200(MT), or SA Shingle Starter as current names. Tarco’s present library uses PS200HT and Quick Roll Shingle Starter and does not list SS400 in its current SDS index.

Choosing and Installing Underlayment

Do not select an underlayment by brand family alone. Match the product to the roof covering, slope, deck, attachment method, climate, maximum service temperature, exposure period, fire classification, and local approval.

Tarco’s ICC-ES report for EasyLay UDL Basic and UDL 50, for example, recognizes specified installations on slopes of 2:12 or greater with mechanically fastened roof coverings and adds other conditions. The NR600 Ultra data page supplies separate properties, permitted uses, and instructions for that self-adhered membrane.

Textured or granular surfacing may improve walkability, but it does not remove fall risk. Contractors must follow the product instructions and required fall-protection practices.

Contractor Support

Tarco publishes product data, specifications, safety sheets, approvals, and technical contacts. No current public contractor-certification program was verified. Ask Tarco or the local distributor about installer training and technical support for the chosen product.

LEED and Environmental Claims

LEED certifies qualifying building projects, not individual roofing products. A Tarco product may contribute to a project credit only when its current documentation and the project’s calculations meet the applicable LEED version.

The old claim that LEED awards points to Tarco products used within 500 miles is obsolete. Current LEED material credits use project-level thresholds, product documentation, responsible-sourcing criteria, and defined regional multipliers. The U.S. Green Building Council’s current credit language should control any project calculation.

Warranty

Warranty terms vary by product. Tarco describes limited material terms of 20, 30, and 50 years for EasyLay UDL 15, EasyLay UDL Basic, and EasyLay UDL 50. Selected self-adhered products carry 30-year limited warranties, while some products receive coverage only against manufacturing defects.

Read the warranty for the exact product and installation date. Application, storage, notice, proof-of-purchase, transfer, access, exclusions, and remedy provisions can affect coverage. A warranty term for underlayment does not guarantee the service life of the complete roof.
