Workarounds Described

custom rigid foam chute/blocking system starting at end of top plate and bringing up to 2 inches below roof sheathing
tying a proper baffle into that custom chute
sealing seams with closed-cell spray foam

Implied Software Gaps

Design tool to custom-fit baffle dimensions for unique roof geometries
Mobile app with laser measurement to generate exact baffle specs for low-heel roofs

App Concept

LowHeel Vent Chute

A pre-formed, adjustable rigid foam baffle system designed specifically for low-heel roof pitches. It bridges the gap between top plate and roof sheathing, creating a continuous air channel from soffit to attic, with integrated foam seals for a tight fit.

Key Features

Adjustable length to fit various heel heights (2-6 inches)
Pre-scored for easy trimming to roof pitch (3:12 to 6:12)
Integrated foam gaskets at top and bottom for airtight seal
Lightweight, rigid closed-cell foam with R-value insulation

Target Users: Professional roofers and attic specialists working on residential low-slope roofs with limited heel height

Revenue Model: $12-$18 per unit, sold in packs of 10; direct-to-contractor via roofing supply distributors or online
