    Description

    Deckguard HT is designed to help in high-temperature applications. The high-temperature resistance allows the membrane to be exposed to heat of 260° F (127° C) or less. It has superior adhesion to the roof deck. Deckguard HT is self-sealing and will seal around nails which will resist leakage caused by water backing up due to ice dams or wind-driven rains. When applied according to specifications and recommendations it will keep the roof deck and supporting structure dry. Deckguard HT is a waterproofing roofing underlayment manufactured for use on sloped roof decks and is suitable under most traditional roof coverings such as shingles for both commercial and residential and metal roofs. Deckguard HT resists water penetration from water backup due to ice dams or wind-driven rain. It also waterproofs potential leak areas such as protrusions, skylights, valleys, and other flashing areas. The Deckguard HT should be used in conjunction with designs that will minimize ice dam formation. It is important to utilize insulation and ventilation to reduce the size of the ice dams in order to reduce the amount of condensation that can build up. This is especially true in the colder climate areas and mountainous regions. Cathedral ceilings must include ventilation between the rafters to allow for airflow to a ridge vent. Many variables can influence the height of the ice dams and the coverage of membrane required. This includes the slope, climate, overhang, valleys, exposure, insulation, and ventilation.
