Overview
- BlockShield SA Plus is a self-adhered, non-asphaltic air and vapor barrier roofing underlayment designed for applications either direct to deck or over a thermal barrier board.
- BlockShield SA Plus is made from a proprietary high strength polypropylene sheet with a very aggressive adhesive layer that effectively bonds to virtually all deck types.
- BlockShield SA Plus can be installed on steep slope roofs (>2”:12”) and on low slope roofs (1/4":12" <2":12") in both commercial and residential construction.
- Top surface is slip resistant, UV stable, and resistant to punctures, tears, and foot traffic.
Product Applications
- Apply directly to galvanized or painted steel Type B Deck
- Apply to thermal board fastened to galvanized steel deck
- OSB
- Plywood
- Gypsum
Safety
- CAUTION: Release liners are slippery. To prevent injury, liner should be removed from under foot as soon as membrane is installed and disposed of properly.
- Persons who access any roofs, involved with roof construction, repair or maintenance shall use appropriate personal protective equipment including, but not limited to, hard hats, eye protection, and leather gloves and must be trained on safe practices relevant to their work.
- Where the use of ladders, scaffolds, platforms, or temporary floors are utilized, safety lines and safety harnesses shall be used. Please access the OSHA Web site at www.osha. gov, contact your local OSHA office, or visit the local federal bookstore to obtain the most current information on OSHA 29 CFR 1926.
Delivery, Packaging And Storage
- Store roll materials vertically on end in original packaging at temperatures between 40°F and 120°F (4ºC - 49ºC).
- Protect materials from direct sunlight and inclement weather until ready for use.
Substrate Information
Steel surfaces must be clear of any oil residue and moisture. Wood decks must be dry to the touch and clear of dirt and dust. BlockShield SA Plus can be installed in 20°F (-6°C) and rising temperatures. BlockShield SA Plus surface is white, reducing the overall temperature gain during installation.
Installation Best Practices
![]() |
![]() |
STEP 1 Once BlockShield SA Plus is in place, while holding the sheet tight, remove the silicone release film by pulling diagonally. |
STEP 2 After multiple rolls are installed, roll the membrane with a weighted roller, min. 70 lbs. |
CAUTION: Release liners are slippery. To prevent injury, liner should be removed from under foot as soon as membrane is installed and disposed of properly.
STEP 3
At the end of each roll, install a metal sheet plate (24 GA x 6"W) to support the end lap between flutes. Ensure 6" (15.2 cm) end laps are maintained on metal sheet plate for each course during installation.

STEP 4 CAUTION: Release liners are slippery. To prevent injury, liner should be removed from under foot as soon as membrane is installed and disposed of properly. |
