App Concept

AtticVent Seal

A retrofittable, adjustable damper system for ridge vents that allows homeowners to reduce airflow in winter without roof modifications. Installed from the attic side, it provides variable vent control to balance insulation and ventilation needs.

Key Features

Adjustable damper plates that slide to partially block ridge vent openings
Easy attic-side installation with foam seals and fasteners
Temperature-sensitive auto-close mechanism for cold weather
Compatible with standard ridge vent sizes (GAF and others)

Target Users: Homeowners in cold climates with ridge vent installations who experience drafts and want to improve energy efficiency without re-roofing.

Revenue Model: $49-$79 per vent kit, sold direct-to-consumer online and through hardware stores
