A spray foam survey checks foam sprayed on the underside of a roof and records what it is and how the timber behind it is coping.
The inspector enters the roof space, records the foam type, thickness and spread, takes moisture readings on reachable timber and photographs what can be seen.
A written report with findings, the limits of the inspection and a clear recommendation, ready to pass to a lender, buyer, solicitor or contractor.
Before a sale or remortgage, after a valuer mentions foam, when you notice damp or staining, or before solar panels or a loft conversion.
