SlopeShield Installation

Printer Friendly (PDF)

Overview

SlopeShield with Integrated Tape is a mechanically attached vapor permeable, weather resistive, roofing membrane, designed as a secondary back-up under the metal roofing material. With a continuous Integrated Tape for vertical lap conditions, SlopeShield is installed immediately before the metal roofing material to limit foot traffic and UV exposure which can degrade the material.

Best Practices

  • SlopeShield is not to be used as a temporary roof covering during the construction period. SlopeShield can sustain up to 4 months of UV exposure but is not intended to be the primary liquid water hold out barrier.
  • Temporary protection measures such as tarps must be used when rain, snow/ice or storm events exist or are anticipated, if SlopeShield is not immediately covered by metal roofing material.
  • Install SlopeShield and metal roofing material using the vertical installation method. This method minimizes installer foot traffic and additional fastener penetrations.
  • SlopeShield with Integrated Tape can be used as an air barrier when all other seams and overlaps are sealed with VaproTape or VaproBond sealant.
  • In geographic locations subject to ice damming, install ice and water shield membranes per applicable building codes, prior to installing SlopeShield.
  • Do not adhere asphaltic-based peel and stick materials to SlopeShield. Butyl-based peel and stick materials are compatible.

SlopeShield should not be used under Asphalt Shingles.

Substrate Information

  • A minimum Roof Slope of 3:12 is required when SlopeShield is used as an underlayment for liquid water protection.
  • SlopeShield may be used as a slip-sheet only, on slopes less than 3:12 (warranty will not apply).
  • SlopeShield can be installed over damp substrates. 
  • See Roof Slope Application Chart below.

Fastening Guidelines

Ensure correct alignment, using the dotted line at the vertical seam, prior to removing release paper.
  • Stainless Steel Staples may be used only at the perimeter where they will be covered by the next layer of material, to temporarily secure the SlopeShield material to the substrate.
  • Avoid placing staples through the Integrated Tape locations.

Installation Method

  • Ensure substrates are clean and free of any contaminants.
  • VaproShield recommends SlopeShield be applied vertically, in the same direction as the roof slope.
  • Along Valleys, Hips and Ridges, install a single continuous layer of SlopeShield parallel to the feature. Fasten at the edges, 12” o.c. (on center).
  • Avoid placing staples through the Integrated Tape locations.
  • Install a course of SlopeShield material onto the substrate, then immediately install metal roofing material onto each vertical run of SlopeShield. This method minimizes installer foot traffic and additional fastener penetrations.
  • Add an additional SlopeShield course and engage the integrated tape to seal the two (2) courses together.

Engaging The Integrated Tape 

MetalRoof Partial
Immediately install metal roofing material onto each vertical run of SlopeShield.
  • Ensure correct alignment, using the dotted line at the vertical seam, prior to removing release paper.
  • Seal vertical overlap seams by slowly pulling both release papers at the same time followed by smoothing both layers together with hand pressure.
  • Once the release paper has been pulled, the seal is permanent.
  • On slopes less than 4:12, all roofing clips must have a patch of butyl tape or use VaproBond Sealant at all fastener penetrations.
  • See Roof Slope Application Chart below.
  • On projects requiring ice dam protection, install butyl-based ice and water shield materials (by others) in proper sequence to ensure shingle fashion application of the SlopeShield material.

  • Seal penetrations and lap seams around pipe penetrations with VaproBond sealant or Tremco Butyl sealant.
  • Detail penetrations prior to the installation of the field membrane.
  • Always ensure overlapping shingle format result.

Repair and Cleaning

  • Measure and pre-cut roof underlayment membrane to cover damaged area with minimum 12 inch overlap to the sides and bottom.
  • Always ensure overlapping shingle format result.

Storage

  • Store in cool, dry location, without direct UV exposure.
