What must be used under shingles for underlayment?

Felt
Inverted shingle
Starter strip
Tar paper

The correct answer is: Felt

Felt is used under shingles for underlayment because it creates a protective barrier between the shingles and the roof decking. Inverted shingles are not used as underlayment, they are used as ridge caps. Starter strip is used for the first row of shingles at the bottom edge of the roof, not for underlayment. Tar paper can be used as underlayment, but it is not as commonly used as felt. Additionally, felt is typically the recommended option for underlayment as it is more durable and provides better protection against moisture.
