We identify the foam and roof build-up first, then explain how much can be removed and whether the membrane is likely to be affected.
What to look for in a Wimborne loft
- Foam covering rafter faces and underlay
- No clear airflow at the eaves
- Roof timbers hidden from view
- A musty or poorly ventilated roof space
- A survey report requesting further inspection
- Foam bonded firmly to older bitumen felt
Why inspection and ventilation matter
The town is less salt-exposed than the coast, but open approaches and winter weather still test ridges, valleys and roof edges. A roof space needs a moisture strategy, and foam can make both inspection and drying more difficult depending on its type and installation.

- 3Moisture held against the timber
- 4Rafters, battens and underlay cannot be inspected
A careful removal sequence
The access route is protected, foam is removed mechanically from accessible timber, waste is contained, and exposed areas are photographed before ventilation and insulation options are reviewed.
Loft survey
We check the foam type, thickness and how much timber is bonded, and price it from what's actually there.
Strip out
Foam cut back from the rafters, battens and underlay, with the loft and access route protected throughout.
Timber inspection
Once the structure's exposed, we photograph it so the roof can finally be properly assessed.
Reinstate
Waste removed, ventilation reopened at the eaves, and insulation put back at ceiling level.
Removal options
Full and partial removal have different implications for inspection and for fragile underlay. The right scope is established after examining the roof rather than promised from photographs alone.
Leave it
Costs nothing today, but the roof stays hidden and any ventilation or inspection concerns remain to be assessed.
Partial strip
Cheaper, and sometimes it's all that's possible on an awkward roof. Any residue left on the timber will still hide parts of the structure.
Full removal
Removal can expose the timber for inspection and allow ventilation details to be reviewed — and we photograph what was underneath.
