Ensuring the underlying roof deck is properly sealed and protected is fundamental to the longevity and performance of any roofing system. The Protecto Roof Deck Seam Tape, offered by A1A Wholesale Supply, provides a cutting-edge solution for sealing roof deck seams, acting as a critical barrier against water, air, and vapor intrusion.

This tape is a cold-applied, self-adhering flashing tape. It is composed of a proprietary slip-resistant, tri-layer, woven polyolefin fabric coated on one side with a layer of high-temperature polymer-modified bitumen adhesive. The 40-mil thickness of the membrane provides robust protection.

A key feature for job site safety is its proprietary slip-resistant surface for added footing safety. This enhances worker stability during installation. The tape also reliably seals around properly installed fasteners and boasts excellent nail sealability, which is crucial for preventing water penetration at fastening points.

Protecto Roof Deck Seam Tape functions as a waterproof, air, and vapor barrier, contributing significantly to the building’s overall energy efficiency and moisture management. It has an extremely low permeance of less than 0.05.

Key Features and Benefits for Contractors:

• Comprehensive Protection: Provides a fully adhered, waterproof, air, and vapor barrier system.
• High-Temperature Performance: Uses a high-temperature polymer-modified bitumen asphalt, suitable for use under steel roofing (note limitations for highly conductive metals). It has an in-service temperature of up to 250°F (121°C).
• Slip-Resistant Surface: Enhances safety for installers.
• Durable & Flexible: 40-mil thickness with a 6-month UV exposure rating and no cracks or delamination in low-temperature flex tests.
• Fastener Sealability: Seals around properly installed fasteners and passes nail sealability tests.
• Versatile Installation: Can be installed horizontally or vertically (as code allows) on roof pitches down to 2″/12″.
• IRC 2015 R 905.1.1 Compliant.

Applications:

• Sealing OSB or Plywood Roof Deck Seams: Primary use to protect the structure by keeping water out of the building.
• New and Re-Roof Applications.
• Roof Deck Protection: Ensures a fully adhered system across the roof deck.

Installation Considerations:

• Surface Preparation: Roof deck surfaces must be clean, dry, and free of foreign materials, gaps, sharp edges, and protrusions. Metal surfaces may require solvent wiping and/or abrasion.
• Priming: Prime DensGlass Gold, DensDeck, masonry, and concrete substrates. For other substrates like OSB, plywood, and gypsum sheathing, prime if adhesion is marginal. Protecto Wrap recommends testing substrates for adhesion.
• Temperature: Apply only in fair weather conditions when air, roof deck, and membrane temperatures are at 40°F (5°C) or higher. For cold weather applications, store products in a warm, dry area between 50°F to 90°F (10°C to 32°C) for at least 24 hours prior to installation.
• Application Method: Install starting at the lowest point of the roof slope and work upward. Center the tape over the seam, apply with a minimum 3″ to 6″ overlaps, ensuring laps shed water. Firmly press or roll all laps to ensure a positive seal.
• Coverage: One 4″ x 66′ roll covers approximately 2 squares of roofing.
• Limitations: Not recommended for roofs exceeding 250°F (121°C) operating temperature. Not for use on roof slopes less than 2″/12″ without approval. Not recommended over granulated surfaces or existing roof coverings. Avoid contact with solvent-based products, polysulfides, plasticized PVC roofing materials, or high concentrations of resins. Copper, Core-Tin, and Zinc roof components can exceed 250°F (121°C).

Warranty & Storage: This product is covered by the Protecto Wrap Standard 10 Year Limited Warranty. Maintain optimum initial adhesion when used within one year from the date of manufacture. Store in original, unopened containers at ambient temperatures between 50°F to 90°F (10°C to 32°C), in a dry area and out of direct sunlight. Do not double stack pallets.
