[[FAQS and GUIDES]] ====Roofing under cold weather==== 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. - http://www.dreamroofs.com/en/02/p_02_061.aspx?id=2 -
