💡 What is the best way to secure synthetic underlayment to wooden roof decking?
Crews usually start by snapping chalk lines so rows stay dead straight across the boards.
- Space fasteners about fifteen inches apart along the field and all perimeter edges
- Lay overlapping strips four inches wide to shut out driving rain during storm surges
- Sink cap nails directly over ceiling joists so wind can never pry the sheet up
- Cut slits near drainage valleys with sharp knives to keep flashing tape perfectly snug
