Wood shingles are fastened to the roof with a minimum of how many fasteners per shingle?

1. 1

2. 2

3. 3

4. 4

The correct answer is: 2

Wood shingles are typically fastened to the roof using a minimum of two fasteners per shingle. This requirement is important for ensuring adequate securing of the shingles to withstand various weather conditions, such as high winds and heavy rain. Using a minimum of two fasteners helps to maintain the integrity of the roof structure by reducing the likelihood of shingles being dislodged over time. The fasteners should be placed in a manner that prevents splitting the wood while ensuring that they are driven deep enough to secure the shingles effectively without compromising their structural integrity. This standard is aligned with building codes to promote safety and durability in roofing installations.
