Total area of the roof in squares; defines material coverage.

Predominant Pitch (/12)

Steeper roofs can alter code requirements for underlayment overlap.

Valley Length (LF)

Total linear footage of valleys—critical leak zones that always need protection.

Eave Length (LF)

Linear feet along roof edges where Ice & Water Shield is commonly mandated.

Soffit Depth (IN)

Determines how far the membrane must extend past the exterior wall.

Determines how far the membrane must extend past the exterior wall.

Default 24 inches, referencing IRC R905.1.2 for required extension.

Exterior Type (Brick, Vinyl, etc.)

Exterior materials influence moisture and fastening considerations.

Why Accurate Exterior Codes Matter

Getting it right the first time prevents expensive consequences.

  • Failed inspections and compliance issues that can trigger stop-work orders and halt the project.
  • Costly tear-outs and rework that erode profit margins, including removal and reinstallation of materials at the contractor’s expense.
  • Negative client reviews and increased liability exposure.
  • Significant delays in claim approvals.
