Done correctly, the foam is hand-stripped from the rafters with zero damage to the timber, restoring your roof to mortgageable, inspectable condition. ## Why spray foam should not be left on a roof Spray foam — particularly closed-cell — traps moisture between the foam and the timber. UK roof spaces are designed to breathe, and once that ventilation is blocked, condensation accumulates against the rafters, leading to fungal decay over 5–15 years. UK mortgage lenders refuse to lend on roofs with spray foam for this exact reason. ## The professional removal method 1. Full property protection — dust sheets, sealed access, negative-pressure extraction 2. Hand stripping using purpose-made scrapers (no grinders, no chemicals) 3. Foam removed in sections and bagged for disposal 4. Timber inspection — moisture readings, decay check, fixings check 5. Optional borate-based timber treatment if required 6. Final clean-down and removal certificate issued ## Why never DIY - Risk of falling through ceiling joists - Risk of damaging slate, tile or membrane from above - Hand strain — full closed-cell removal can take 40+ hours - No mortgage-acceptable certification at the end - VOC and dust exposure ## Cost expectation Roof spray foam removal costs typically £40–£110 per m² depending on foam type. Most UK homes fall between £2,500 and £6,500. See the full [UK cost guide](/spray-foam-removal-cost-uk). ## Frequently Asked Questions Can spray foam be removed from a roof without damaging tiles?
