Collection point and outlet
Ask where the valley drains and whether the path is clear. An interior collection point needs a property-specific drainage review.

Butterfly Roofs in Miami: The Central Valley Matters
Two roof planes fall toward the center instead of away from it. The dramatic V-shaped form puts the central valley and its drainage at the heart of the inspection.

READ THE ROOFLINE
How does a butterfly roof work?
A butterfly roof has two inward-sloping planes that meet at a central valley. It is essentially an inverted gable silhouette. Its form concentrates runoff in the middle rather than scattering it around the perimeter.
Miami roof planning must account for the building and the exact assembly. Miami-Dade's roofing permit guide separates roof categories and system details; requirements for a specific job must be checked with the proper jurisdiction.

What should be checked at the central valley?
A proposed repair or replacement should explain the relevant details, not simply repeat the roof shape.
Valley waterproofing
The central junction receives water from both planes. Its assembly and any signs of deterioration deserve particular attention.
Overflow and access
A proposal should account for how water behaves if an outlet is obstructed and how the roof can be accessed for maintenance.
FORM IS NOT FINISH
Can a butterfly roof use any roofing system?
The geometry alone does not answer that. The slope of each plane, central valley design, roof structure and approved assembly must be evaluated together before a system is recommended.

Butterfly roofs: Common Questions
Clear answers make it easier to choose the right next step for your property.
01Is a butterfly roof the same as a gable roof?
No. A conventional gable sheds water outward from a central ridge. A butterfly form slopes inward toward a central valley.
02Why is the center of a butterfly roof important?
Both roof planes direct water there, so the valley and drainage outlet are critical details to inspect.
03Does DOM currently service butterfly roofs?
This page is educational. DOM must confirm the responsible team, system capability and coverage for a specific address before offering work.

ROOF SHAPE
Gable roofs
Two sloping planes meet at one ridge. The silhouette looks simple, but the ridge, eaves and wall transitions still deserve a careful inspection when water appears inside.
ROOF SHAPEHip roofs
A hip roof slopes down on every side. Its layered planes can look beautifully resolved from the street, while their intersections add details that matter when diagnosing a leak.
ROOF SHAPEFlat & low-slope roofs
“Flat” roofs still need a way to move water. For a home addition, shop, office or warehouse, drainage and the complete roof assembly matter more than the label alone.
