What is the purpose of a starter strip in shingle installation?

• A. Decorative only.
• B. To hold nails.
• C. Provide proper nailing line and wind uplift protection.
• D. To increase weight.

Answer: (C)

Starting with the main idea: the starter strip creates a solid, straight base at the eave that defines the exact nailing line for the first course and helps protect against wind uplift. With a true edge, the first row seats correctly and nails are placed in a consistent location, reducing the chance of exposed nail heads and leaks behind the first row. It also provides a sealed edge to improve water shedding and keeps the bottom of the first course secured against uplift. This function is practical and essential; it’s not decorative, it doesn’t serve to hold nails for you, and it doesn’t significantly add weight.
