Final answer:
To secure roof underlayment, you can use nails, screws, or staples. The choice depends on factors like roofing material, building codes, and installation preferences.
Step-by-step explanation:
To hold the roof underlayment in place, you can use various types of fasteners.
These include 1) nails, 2) screws, and 3) staples.
Each of these fasteners has its own application depending on factors such as the type of roofing material, the local building codes, and the preferences of the roofing professional.
However, it is crucial to choose the right type of fastener for a secure and lasting installation.
For example, nails are often used for their quick application and strong holding power, screws provide excellent durability and can be used where wind uplift is a concern, and staples are fast to apply but may not provide as strong a hold as nails or screws in high-wind areas.
