Choose the main task. Existing foam problems take a separate path.

Project conditions

The attic floor and roof deck create different enclosure boundaries.

Include the cavity, substrate, utilities, and where expanding material could travel.

Include old stains, seasonal leaks, mold-like growth, rot, and unexplained dampness.

Include people, pets, adjacent units, and connected heating or cooling air paths.

Check for natural-draft combustion appliances, flues, high heat, electrical equipment, and fire-rated walls or penetrations.

A small container does not make a whole-room project a small task.

How the planner works

Good questions lead
to better decisions.

Moisture and unknown boundaries come first. Concealed conditions, work-zone controls, special hazards, large projects, and roof or crawlspace changes lead to professional review. A simple gap-sealing task can lead to product-format research.

These are conservative editorial routing rules, informed by EPA spray foam guidance (archived), EPA moisture guidance, and DOE Building America’s roof-assembly guidance. The planner covers walls, attic floors, roof decks, crawlspaces, basement walls, and rim joists. It does not evaluate vehicles, pools, cold rooms, specialty roofing, or every area in the application atlas. Those projects need their own assessment. Your site may need additional checks.
