3. PRODUCT DESCRIPTION
Basic Uses:
ATA-Shield is a self-adhering underlayment
designed specifically for use under metal
roofing. This membrane is well suited for use
where a water resistant barrier is required.
It is formulated to withstand the high heat
environment generated by some metal
roofing systems.
Composition and Materials:
ATA-Shield is composed of an unreinforced
polymer-modified bitumin material adhered
to the underside of a polymer-coated
synthetic woven material.
Size:
The ATA-Shield membrane is 45 mils thick
and is available in rolls 3’ wide by 72’ long.
Each roll weighs 48 pounds and covers
approximately 200 sq. ft. of roof surface. Split/
perforated release backing film aids in easy
positioning of sheets to maintain a proper line.

5. INSTALLATION
Recommended Application:
ATA-Shield uses include, but are not limited to,
application under metal roofing where a water
resistant barrier is required. It is also suited
for application in desert climatic conditions.
ATA-Shield has been specially formulated to
be high temperature resistant up to 240°F.
Installation manuals or hands-on training via
seminars are available through ATAS. Visit
www.atas.com for more information.
Application Methods:
ATA-Shield must be installed above properly
ventilated areas, as it’s considered a vapor
barrier. Apply ATA-Shield only in dry weather,
when the air, membrane and the substrate
are at temperature over 40°F. Protect
completed roof areas to avoid damage during
roof installation and material transportation
by installing protective boardwalks to
enable passage of people and products. It
is recommended to use a double layer of
ATA-Shield and repair any damage in critical
areas, such as the valleys or along the eaves
in climates where severe ice damming is
expected. For high wind or wind driven rain
protection it is recommended to cover the
entire roof deck with ATA-Shield.
ATA-Shield is to be laid out horizontally
(parallel) to the eave with the printed side
up, using 3” horizontal laps and 6” vertical
laps. Prior to application of the second course
remove the white release liner tape to expose
the lap seal asphalt. Care should be taken not
to walk on or contaminate the lap seal once
exposed.
Apply the membrane in valleys before the
membrane is applied to the eaves. Cut the
membrane into 10 -15 foot lengths and re-roll
loosely. Peel back 1-2 feet of release liner,
align the membrane, and continue to peel the
release liner from the membrane. Hand press
first followed by a heavy pressure roller to
smooth and secure the membrane, especially
at the overlaps layers. For valleys and ridge
applications, peel the release liner; center
the sheet over the valley or ridge, drape, and
hand press in place followed by a pressure
roller. When left exposed prior to application
of primary roof covering, secure membrane
in place, carefully sealing the laps, to protect
against uplift from wind exposure.
6. AVAILABILITY AND COST
Availability:
ATA-Shield is available through ATAS product
distributors.
Cost:
Contact ATAS product distributors for cost.
7. WARRANTY
ATA-Shield is covered by a thirty (30) year
limited warranty.
8. MAINTENANCE
General Storage Requirements: All materials
should be stored in their original unopened
packaging. Roll goods shall be stored on
end on a clean flat surface. Store all roofing
materials in a dry place, on raised platform,
out of direct exposure to the elements until
time of application. This requirement applies
equally to rooftop materials, temporarily on
the roof before installation. Store membrane
at room temperature whenever possible
until immediately prior to installing the roll.
Materials shall be stored in a safe way in order
to avoid exceeding the allowable live load of
the storage area. Do not double stack pallets
of ATA Shield membrane.
