Best-in-class Metshield® ice and water
underlayment protects the roof structure
from water seepage caused by ice dams
and wind-driven rain. Designed specifically
for high-temperature applications of metal
roof installations, it will resist temperatures
up to 250° without degradation of the
adhesive, and self-seals around roofing
nails, screws and clips used to install the
primary roofing system. This high-tensile
strength underlayment is a 40 mil SBS
modified bitumen with a UV-resistant anti-slip
polyethylene woven top facer and is required
under all Drexel Metals roof warranted
systems.
Features and Benefits
• Protects the roof structure from water seepage caused
by ice dams and wind-driven rains
• Resists temperatures up to 250°F without degradation of
the adhesive
• Seals around roofing nails, staples and screws
• Bonds directly to the roof substrate for fast and easy
installation without the need for additional adhesives
• Split-release film provides easier, faster installation
• Resists cracking, drying and rotting, providing long-term
waterproofing performance and low lifecycle cost
• Concealed waterproofing system will not detract from the
architectural aesthetics of the primary roofing system
• Exposed rubberized asphalt bead along the membrane
edge ensures watertightness of lap seams
• Made in USA
Standards
• UL Classified
• ICC-ES ESR #2206
• 2009 and 2012 International Building Code™

• Meets ASTM D1970
Storage
MetShield roofing underlayment rolls should be stored on
end, under cover and in areas where the temperature is
between 40° and 100°F (4.4° and 38°C). Do not double-
stack pallets.
Warranty
MetShield is backed by Drexel’s industry-leading warranty.
Visit our website for warranty details.
Installation
MetShield underlayment is applied when the roof deck
is dry and the substrate temperature is 40°F (4.4°C) or
higher. At temperatures below 40°F, nailing or priming
should be used to temporarily hold the membrane in place
while adhesion develops. MetShield is designed to be
covered with the primary roofing system and should not be
exposed to sunlight for more than 120 days.
Moisture: Substrate must be free of any moisture. If
moisture is present, it may inhibit adhesion.
New construction: Prepare the roof deck by removing all
loose objects, dirt, dust and debris.
Re-roofing: Remove all old materials from the roof deck
in the area to be covered with MetShield underlayment.
