Deckguard® HT Roofing & Watershield Underlayment

Deckguard® HT is a high heat 40-mil roofing membrane composed of a high strength slip resistant spider web backing laminated to a high performance high heat asphalt compound with a film release for ease of application.  The release liner is removed leaving a strong asphalt compound to bond to the roof deck.

Deckguard® HT is designed to help in high temperature applications.  The high temperature resistance allows the membrane to be exposed to heat of 260° or less.  It has superior adhesion to the roof deck.  It 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.
