Low Slope Installation

• Gypsum Roof Sheathing Board
• Rigid Insulation
• Concrete (Bull bloat finish or better)
• Plywood

• Mass Timber
• Steel Deck Pre-painted galvanized metal
• Aluminum Painted/Mill finish
• OSB (Contact VaproShield Technical)

• DO install on roof applications with a minimum slope of 1/4:12
• DO ensure all side and head laps are a minimum of 3” (7.5 cm)
• DO roll the membrane with a weighted roller, min. 70 lbs
• DO use VaproTape on all seams when using SlopeShield Plus SA for temporary weather protection on low slope roofs
• DO install in a shingle fashion perpendicular to the roof slope with VaproTape in low lying areas, such as drains, valleys, etc
• DO install above of 20˚F (- 6.0˚C) and rising
• DO cover membrane as soon as practical, maximum exposure time is 180 days
• DO ensure surfaces are in sound, clean condition and free of oil, grease, dirt, excess mortar or other contaminants
• DO fill voids and gaps in substrate greater than ½” (12.7 mm) wide
• DO conduct on-site adhesion testing along with moisture meter testing, prior to installing new insulation and roof membrane
• DO use primer as required to meet uplift pressures*

• DON'T install reverse laps or install seams against the flow of water
• DON’T install below 20˚F (- 6.0˚C) and decreasing
• DON’T install on a roof below 1/4:12 without prior written approval from VaproShield Technical
• DON’T leave release liner underfoot, dispose immediately
• DON’T store materials in direct sunlight and inclement weather until ready for use

IMPORTANT INSTALLATION NOTE EXPOSURE TIME
When using SlopeShield Plus SA in a self-drying application or as temporary weather protection, all seams must be taped and rolled with a weighted roller to ensure proper adhesion.

LOW LYING AREAS, DRAINS
Under 1/4:12 or in low lying areas, such as drains and valleys, VaproTape is required on all seams 1 foot on either side of the drains.

Note: VaproLiqui-Flash (min. 30 wet mil.) can be used as an alternative to VaproTape for sealing seams in damp environments. Refer to VaproLiqui-Flash installation instructions.

Step 1
Starting at the low point of the roof, unroll SlopeShield Plus SA onto the clean, dry substrate.
Once leading edge is set, while holding the sheet tight, remove the silicone release film by pulling diagonally.

Step 2
When installing subsequent rolls of SlopeShield Plus SA ensure 3” (7.5 cm) side laps are maintained.
After multiple rolls are installed, roll the membrane with a weighted roller, min. 70 lbs.

STEP 3
When left exposed to precipitation, positive slope and adequate drainage is required. The effects of weathering may vary based upon local climate and project conditions. May be used as temporary protection at the discretion of the general contractor or building professional. Maximum exposure is 180 days prior to coverage.

STEP 1
Ensure factory-applied oil has been weathered or removed from the deck.

Starting at the low point of the roof, unroll SlopeShield Plus SA onto the clean, dry substrate.

STEP 2
Sequence work to plan placement of head laps.

When installing subsequent rolls of SlopeShield Plus SA ensure 3” (7.5 cm) side laps are maintained.

STEP 4
When left exposed to precipitation, positive slope and adequate drainage is required. The effects of weathering may vary based upon local climate and project conditions. May be
used as temporary protection at the discretion of the general contractor or building professional. Maximum exposure is 180 days prior to coverage.

STEP 1
1A: Concrete deck installed by others

STEP 2
2A. Prime surface as required. Contact VaproShield Technical for primer requirements.

STEP 3
3A. Starting at the low point of the roof unroll SlopeShield Plus SA onto primed surface.

3B. Once placed, while holding the sheet tight, remove the silicone release paper. Remove release paper from under foot.

STEP 4
4A. Install subsequent rolls of SlopeShield Plus SA ensure a 3" min. (7.5 cm) side laps are maintained.

4B. After multiple rolls are installed, roll the entire section of installed membrane with a weighted roller, min. 70 lbs.
