Roof Insulation Scope Builder

Build a focused roof insulation scope

This tool is intentionally narrow. It does not estimate a price, guess at code requirements, or pretend a checkbox can inspect an attic. It organizes the first decision: what should be investigated before insulation material is added or removed.

Choose the conditions that match the home. The recommendation changes as symptoms point toward air leakage, ventilation obstruction, moisture, contamination, or simple depth loss.

How to read the result

The result is a starting point, not a final specification. If the home has moisture, staining, frost, or odour, adding insulation without diagnosis can bury the evidence. If the home is simply shallow and dry, a top-up may be reasonable after baffles and air leakage are checked.
