When installing felt paper underlayment with nails, it is important to follow these best practices:
- Start at the bottom of the roof and work your way up.
- Overlap the felt paper sheets by at least 2 inches.
- Use galvanized nails to secure the felt paper, placing them every 6-8 inches along the edges and every 12 inches in the field.
- Avoid overdriving the nails, as this can tear the felt paper.
- Trim any excess felt paper at the edges to ensure a neat and secure installation.
