When using wood shingles on low-sloped roofs, how many layers of shingles should there be at any point?

When using wood shingles on low-sloped roofs, typically, there should be at least three or four layers of shingles at any point. This requirement stems from the need for increased water resistance and durability in areas subjected to more significant moisture exposure due to the roof's angle. The additional layers help ensure that water does not penetrate the roofing system, which can lead to leaks and damage over time.

On low-sloped roofs, water has a higher tendency to pool, so having multiple layers of shingles provides added protection against water infiltration. Each layer acts as a barrier, reducing the risk of moisture reaching the underlying roof structure. Furthermore, more layers can improve the overall insulation and aesthetic appeal of the roof, which is particularly valuable in regions prone to varied weather conditions. It's important to adhere to local building codes and manufacturer guidelines, as they may specify the minimum number of layers required for different roofing applications.
