A small roof projection built over a window, featuring a continuous wavy or arched roofline that blends smoothly into the main roof pitch without sharp valleys. Framing and flashing these structures requires complex carpentry and custom shingle work to shed water effectively without standard metal valleys.
The framers are struggling with the curved rafters on that eyebrow dormer above the garage.
Because they lack standard vertical sidewalls and valleys, eyebrows rely entirely on the overlapping flexibility of the shingles to stay watertight.
