Spray Foam Removal
Griffith Avenue

Spray foam roof insulation was widely applied in Irish homes from the 1980s through to the 2000s, marketed as an energy-saving measure for the attic space. Peak Roofing and Building carries out professional spray foam removal across Griffith Avenue, covering both open-cell and closed-cell foam systems. Two types were commonly used: open-cell foam, which is soft and slightly permeable, and closed-cell foam, which sets hard and is completely impermeable to water vapour. Closed-cell foam in particular is the more serious problem — it creates a sealed vapour barrier across the underside of the roof structure, trapping moisture inside the roof void. Over time, that trapped moisture condenses and causes rot in the roof timbers beneath. The critical issue is that the foam physically encases the rafters, making it impossible for surveyors or structural engineers to see the condition of the timber underneath — which is precisely why so many lenders in Ireland and the UK will now decline to mortgage or remortgage a property until the foam has been professionally removed and the underlying timber structure assessed and certified.
