Mixed roof geometry is common on South Florida homes, especially where an addition meets the original structure. This photo set highlights architectural shingle courses, valley detailing and the visible transition between the sloped shingle field and a low-slope section.

Aligned courses and clean valley work are visible signs of care. Much of what determines how a mixed-slope roof performs, though, is covered before completion — underlayment, flashing and the tie-in between the two systems.
