WARNINGS & PRECAUTIONS
WARNING: Roofing application can be dangerous. All necessary precautions and safety guidelines
should be observed in accordance with proper roofing trade practices. Every effort should be made
to keep roof traffic to a minimum. Regular roof maintenance should be performed in the cooler
parts of the day. Important Precautions: Store on flat surface. Protect from weather during storage
and on job site. Sealant protection tape is placed on the back of each shingle and does not have to
be removed before applying.
DISCOLORATION: Some shading or variations in the colors may occur due to positioning or
embedment of the granule. When asphalt shingles are packaged, they are under a certain amount
of pressure due to weight. Minor staining may occur. While in storage, they may also pick up
varying amounts of backing material used to keep the shingles from sticking together. These
discolorations are temporary and are removed by natural weathering.
DO NOT MIX WITH MATERIAL BEARING DIFFERENT COLOR NAME OR OTHER PRODUCT SIZES ON
THE SAME ROOF.
