Felt paper is your last line of defense for any water that gets blown into or leaks through the shingles. It also acts as a vapor barrier to keep your roof sheeting from drawing moisture.

Because tiles and slates are not sealed down, instead they just hang, so if the wind is strong it can push rain up under the tiles. Felt acts as an interior run off and stops the joists going rotten.

This is a secondary water intrusion defense in case of damage to the initial roof material.
