Homeowner wants to add insulation under roof sheathing in a vented attic to reduce heat transfer, but is unsure of the best approach and materials.
Existing blown-in insulation (4-5 inches) is insufficient to reduce heat gain in south-facing rooms, and the homeowner lacks clear guidance on adding rigid foam insulation under roof sheathing in a vented attic while maintaining proper ventilation.
AtticInsight Roof Insulation Planner
An interactive tool that guides homeowners through selecting and installing roof insulation for vented attics. It assesses existing conditions (e.g., attic dimensions, current insulation, roof pitch) and recommends materials (rigid foam, etc.) with step-by-step installation instructions and ventilation best practices. Integrates a materials calculator and local climate adjustments.
- Attic assessment questionnaire (dimensions, current insulation, roof pitch, vent type)
- Personalized insulation material recommendation (rigid foam R-value, thickness, fit) with ventilation compatibility check
- Step-by-step installation guide with diagrams and safety tips
- Materials and cost estimator based on local pricing
- Climate-specific advice for heat reduction and moisture control
