6013BR Roof Dryer Vent Flap

This is the type that came with our new house that has orange concrete "S" Shape roof tiles. I broke the flapper with a screwdriver while trying to unclog it & remove lint.Our roofer said it should be used for flat roof tiles, not ours. So we bought a new dryer vent that is like the other roof vents we have which is round with a removable "hat" or top on it.

The vent flap seems to work well. Think this unit should last many years.
