A roof should have a minimum slope of 2:12 (approximately 9.5 degrees) to effectively use asphalt shingles. This means that for every 2 inches of vertical rise, there should be at least 12 inches of horizontal run. Roofs with slopes lower than this can lead to water pooling and potential leaks. For steeper slopes, additional considerations for installation and ventilation may be necessary.
