1. What is the primary roof construction type?

Cut timber roof (traditional rafters and purlins) Trussed rafter roof (modern fink trusses) Vaulted ceiling / Room in roof (plasterboard attached to rafters) Flat roof (timber joists) Scottish sarking (timber boards over rafters)

2. What is the primary external roof covering?

Interlocking concrete tiles Natural slate Clay tiles Plain tiles Other (e.g., metal, felt)

3. What substrate was the foam applied directly onto?

Direct to the underside of tiles/slates (no underlay present) Bitumen/1F non-breathable felt Breathable membrane Timber sarking boards Plasterboard / Lath and plaster

4. What type of foam has been installed?

Open-cell (low density, spongy, easily compressed) Closed-cell (high density, rigid, hard) Combination / Layered (e.g., closed-cell over open-cell) Cannot determine on-site without lab testing

5. What is the average depth/thickness of the foam application?

Under 50mm 50mm – 100mm 100mm – 150mm Over 150mm

6. What is the level of timber encapsulation?

Partial: Sprayed between rafters only (rafter faces fully visible and clear) Moderate: Overspray on rafter faces, but shape of timber is clearly defined Total: Timbers are completely encapsulated (cannot see or locate rafters easily)

7. What is the average Wood Moisture Equivalent (WME) reading of the accessible timbers?

Dry: < 15% WME Borderline / Damp: 16% – 19% WME Wet / At Risk of Decay: 20% – 28% WME Saturated: > 28% WME

8. Are there visible signs of timber decay or fungal growth?

None visible Wet rot (soft, spongy, localized darkening) Dry rot (cuboidal cracking, mycelium, pancake fruiting bodies) Frass or boreholes (active/historic wood-boring insect attack) Delamination of manufactured timbers (e.g., OSB/plywood splitting)

9. What is the state of the existing roof space ventilation?

Adequate: Clear airflow at eaves, ridge, or via tile vents Blocked: Eaves blocked by foam overspray or insulation None: No cross-ventilation present in the void Unvented system (but failing to perform as a warm roof)

10. Are there electrical hazards present within the spray foam?

None visible Lighting cables encapsulated in foam Power cables (e.g., shower, solar PV, ring main) encapsulated in foam Junction boxes buried in foam (High risk)

11. Is there any visible or suspected Asbestos Containing Material (ACM) in the work area?

No suspected ACMs Cement flue pipe passing through the loft Artex/Textured coating visible on ceilings below Asbestos cement roof tiles/slates Asbestos insulating board (AIB) present (e.g., firebreaks)

12. How would you rate the internal access for the removal operatives?

Good: Large hatch, boarded walkways, full standing height at apex Fair: Standard hatch, unboarded (joist walking required), limited head height Poor: Very tight hatch (< 500mm), restrictive truss webs, shallow pitch (crawling only) Restricted: Large obstructions (e.g., header tanks, chimney stacks, MVHR units) blocking access

13. Did the homeowner receive a comprehensive handover pack at the time of installation?

Yes, full documentation pack is available for review. Partial documentation only (e.g., just an invoice or a basic leaflet). No documentation available / Paperwork lost. Unsure (installed by previous owner with no records passed on).

14. Is there a documented, property-specific Condensation Risk Assessment (CRA) available?

Yes, a property-specific CRA is present and appears robust. Yes, but it appears to be a generic/templated document rather than property-specific. No Condensation Risk Assessment was provided.

15. Is there evidence that the installed spray foam is a BBA (British Board of Agrément) or KIWA accredited product?

Yes, BBA or KIWA certificate number is clearly documented for the specific product used. The product is named, but no formal accreditation certificate is included. Product is unnamed / No evidence of BBA or KIWA accreditation.

16. Does the homeowner possess a valid manufacturer or installer warranty?

Yes, Manufacturer Product Warranty (usually 20-25 years). Yes, Installer Workmanship Guarantee. Yes, both Manufacturer and Installer warranties are present. No warranty paperwork is present. The original installation company has ceased trading (installer warranty is likely void).

17. Is there an active Insurance Backed Guarantee (IBG) in place for the installation?

Yes, a valid, independent IBG certificate is present. No IBG was provided or is present. Unsure / Cannot verify from the paperwork provided.

18. Are there pre-installation photographs available showing the condition of the roof structure before the foam was applied?

Yes, comprehensive and clear photos showing healthy timbers and a dry roof space. Yes, but limited in scope, blurry, or missing key structural areas. No pre-installation photographs are available.

19. Based on the available paperwork, does the original installation meet the PCA Inspection Protocol for retainment?

Fully Compliant: All PCA criteria met (CRA, IBG, BBA/KIWA, Photos). Foam may potentially remain if physically sound. Partially Compliant: Missing critical elements (e.g., no CRA or no IBG), but product is accredited. Further investigation required, may require removal.
