What is the minimum roof slope that allows for the application of mineral surfaced roll roofing?

1:10
1:12
1:8
1:5

The correct answer is: 1:12

The minimum roof slope for the application of mineral surfaced roll roofing is 1:12. This slope is significant because it ensures that water can effectively drain off the surface of the roof, minimizing the risk of water pooling, which can lead to leaks and other moisture-related problems. A slope less than 1:12 is not recommended for this type of roofing material, as it may not allow for adequate drainage and could potentially lead to premature wear or damage to the roofing system. The choice for a 1:10, 1:8, or 1:5 slope, while they are steeper and can work for roofing, are not the minimum required slope and therefore are not suitable answers for this question. The 1:12 slope effectively balances the need for drainage while still providing a manageable inclination for roofing installation, making it the standard minimum in many building codes and roofing guidelines.
