High temperature ice and water shield is designed for roofing systems where the underlayment is exposed to higher heat levels created by the roof covering itself. This category includes membranes engineered to handle the elevated temperatures found under metal roofing and other materials that conduct or retain heat. Contractors choose these products when standard ice and water shield may soften or fail under these conditions.

These high temp membranes provide strong adhesion, consistent moisture protection, and stable performance beneath metal and other demanding roof assemblies.

Why Contractors Use High Temp Ice and Water Shield

High temperature ice and water shields are used primarily under metal roofing, where the panels can trap heat and transfer it directly to the underlayment. This type of roofing underlayment high temp option prevents membrane slipping, wrinkling, or degradation caused by metal expansion and heat buildup. Contractors rely on these products to protect critical areas of metal roof systems and maintain long-term performance.

Key Benefits

  • Designed specifically for use under metal roofing systems
  • Stable bonding performance in high heat transfer conditions
  • Helps prevent membrane slippage and deformation under metal panels
  • Provides strong moisture protection against ice dams and wind-driven rain
  • Suitable for valleys, eaves, transitions, and fastener-heavy areas
  • Durable roofing underlayment high temp option for demanding installations

Technical Notes

Products in this category include high temp ice and water shield membranes engineered to resist heat generated by metal roofing. These underlayments maintain adhesion and seal around fasteners even when exposed to elevated temperatures beneath metal panels. They are built primarily for heat generated by metal roofing, and are also a good fit in very hot climates or any roof assembly that traps heat against the deck.

Use Cases

Contractors use high temperature ice and water shield in:

  • Metal roofing applications (primary use case)
  • Standing seam and exposed fastener metal systems
  • Roof areas where metal expansion increases heat load
  • Valleys, eaves, and transitions beneath metal panels
  • Can be used for the entire roofing job
  • Projects requiring enhanced protection under roofing materials that conduct heat
