In roofing, the choice of shingles is closely related to the slope of the roof. A slope of 4:12 or greater is generally the minimum requirement for the effective use of asphalt shingles. This specific slope ensures that rainwater effectively runs off the roof rather than pooling, which can lead to leaks and damage.

At this slope, shingles can create the necessary angle to shed water efficiently while providing adequate coverage and support. Moreover, using shingles on roofs with pitches lower than 4:12 can increase the risk of water infiltration and may require a different roofing material or additional waterproofing measures to prevent leaks.

Shingle manufacturers typically specify this slope because it ensures the optimal performance and longevity of the roofing system. Hence, a 4:12 slope is considered a standard guideline in roofing construction and is essential for maintaining the integrity of the shingles over time.
