Asphalt shingles, when installed properly, have proven to be very resistant to strong winds. Self-sealing asphalt shingles have a factory applied adhesive that is activated by heat, thus roof temperature is important.
Though most shingle manufacturers warrant their shingles for wind speeds of 100 km/h (60 miles/h) or more, reducing roof damage caused by wind can be accomplished by taking some simple precautions, especially if you are in an area known to have periodic high winds or very dusty conditions.
Although some of the recommendations above may exceed minimum building code requirements, following any of them will help ensure a more wind-resistant finished roof, avoiding the potential inconvenience and stress of insurance claims, roof repairs, and possible internal building damage/repair.
