Cold weather guidelines:

• Traffic on the roof should be avoided as ice, snow and frost make the surface hazardous and can also cause shingles to break or crack.
• When removing snow, avoid direct contact with the shingles as this will scrape off the protective granules.
• When applying shingles in temperature below 0°C (32 °F), handle the product with care as the shingles become more brittle. Never force or drop shingles in cold weather as they may crack or break.
• If shingles are installed during the colder months, the tabs of the shingles should be sealed down manually using BP Multi-Purpose Plastic Cement as the sun is not warm enough to activate the adhesive strips.

NOTE: The amount of plastic cement used when sealing down shingles should not exceed two spots under each tab, no larger, or thicker than a quarter.
