IMPORTANT: THE STATEMENTS EXPRESSED ON THIS WRAPPER ARE THE RECOMMENDATIONS FOR

THE APPLICATION OF THE ROOFING PRODUCTS AS OUTLINED AND ILLUSTRATED. ANY DEVIATION

FROM THESE RECOMMENDED PROCEDURES SHALL BE AT THE SOLE RISK OF THE INSTALLERS.

FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN SERIOUS DAMAGE TO THE APPLICATION

AND LIFE OF THIS ROOFING PRODUCT, RESULTING IN THE TERMINATION OF ANY WARRANTY,

EXPRESSED OR IMPLIED.

1. GENERAL INSTRUCTIONS

These GlassMaster shingles are warranted against manufacturing defects and wind gusts up to 60

MPH. The GlassMaster® 30 Limited Warranty can be obtained by visiting

www.AtlasRoofing.com/Warranty, or by writing to: Atlas Roofing Corporation, Attn: Consumer

Service Department, 2564 Valley Road, Meridian, Mississippi, 39307. The following instructions

must be followed to qualify for protection under the GlassMaster® 30 Limited Warranty.

Important: See special instructions below for Low Slope Applications. See special instructions below

for Steep Slope/Mansard/ High Wind application. To obtain stated area coverage and to achieve

design performance and appearance, the directions on this package must be followed. Sealing of

the adhesive strips on each shingle to the shingle beneath is created by heat from sunlight. Atlas

Roofing Corporation also endorses the Asphalt Roofing Manufacturers Association’s (ARMA)

recommendations for application details not specified within this text.

Important: Do not apply GlassMaster® 30 shingles on roofs having a slope less than 2" per ft. See

special instructions for Low Slopes (2" to 4" per ft.) and for Steep Slope/Mansard/High Wind

application. To obtain stated area coverage and to achieve design performance and appearance,

the directions on this package must be followed. Sealing of the adhesive strips on each shingle to

the shingle beneath is created by heat from sunlight. Sealing may be delayed if shingles are

applied during cooler temperatures, or to roof areas that do not receive direct sunlight. Dust

accumulation may also further delay sealing. If any of the strips have not activated properly after a

reasonable time period, hand sealing may be necessary. Shingles in prolonged storage may pick up

temporary staining, which is removed by natural weathering. Double stacking can cause staining

and sticking in the bundle. Atlas Roofing Corporation also endorses the Asphalt Roofing

Manufacturers Association’s (ARMA) recommendations for application details not specified on this

wrapper.

2. ROOF DECK VENTILATION

Adequate ventilation under the roof deck must be provided to prevent harmful condensation in

winter and heat build-up in summer. These conditions can cause:

A. Accelerated shingle weathering B. Deck rot and attic fungus C. Shingle distortion/cracking due to

deck movement D. Cosmetic blisters on the shingle surface.
