By AEP Span. 

This concealed waterproofing system protects the building from wind, rain and ice and is now part of the Full System Warranty! 

AEP Span's top-notch underlayment solution, AEP Span Underlayment HT, has now been included in the Full System Limited Weathertightness Warranties offered by AEP Span. This means better building protection under your steel or aluminum roofing against extreme weather events.  

AEP Span Underlayment HT is a high-tensile strength, rubberized, asphalt underlayment specifically designed to withstand temperatures up to 250°F (121°C). This concealed waterproofing system will not detract from the architectural aesthetics of a primary roofing system and seals around roofing nails, staples and screws. 

AEP Span Underlayment HT is a strong, skid-resistant membrane that provides superior protection from water penetration caused by wind-driven rain and ice dams. 

Our split-release film provides easier, faster installation and resists cracking, drying and rotting, providing long-term waterproofing performance and low life cycle cost. 

AEP Span Underlayment HT is backed by our defect warranty and will display optimal performance when stored under recommended conditions and used within one year of manufacture date. 

AEP Span Underlayment HT is offered for all roofing products and is required to be used with the following standing seam roof products to be eligible for a Manufacturer’s Limited Weathertightness Warranty: 

  • Design Span® hp 
  • Select Seam Narrow Batten 
  • Span-Lok TM hp 
  • Aluminum Span-Lok TM hp 
  • Span-Lok TM/Curved Span-Lok TM 
  • SpanSeam TM 

AEP Span Underlayment HT is available as an option for all AEP Span roof profiles regardless of a Full System Weathertight Warranty or not. 

Enjoy the convenience of working with one vendor for your entire installation and benefit through reduced administrative hassle and costs.
