Open-Cell Spray Foam Removal and Re-Roofing in Wrexham
Countrywide Roofing & Insulation removed approximately 80m² of open-cell spray foam from a property in Wrexham and replaced the roof covering, with new loft insulation and roofline improvements completed as part of the same project. The foam had been sprayed directly onto the tiles and roof structure.

Why the roof covering needed replacing
The existing tiles were bonded to the spray foam and identified as unsuitable for reuse. The solution was to remove the covering and rebuild the roof above the timber framework.
Our team stripped the tiles and foam-covered battens, then removed the remaining foam from the rafters, ridge boards, hips and apex. The exposed timber surfaces were cleaned before reinstatement.
The replacement roof
The new roof was built up with breathable membrane, 25mm × 50mm treated battens, over-fascia ventilation strips and felt support trays at the eaves. Marley concrete interlocking tiles, half-round concrete ridge tiles and a ventilated dry ridge system completed the roof covering.
Scaffolding, waste disposal and temporary weather protection were included within the project.
Loft insulation and roofline work
We installed Knauf mineral wool to a minimum depth of 300mm within the loft areas. New guttering was fitted and the existing fascia boards and soffits were over-capped in uPVC, making use of the same scaffold access.
The handover included a photographic record, Building Control completion documentation where required and a 10-year insurance-backed guarantee on the new roof.
