After a concrete deck is screeded and waterproofed, residual moisture often remains trapped within the structure. Without proper ventilation, this trapped moisture can cause a range of problems, including:\n\nBlistering of asphalt or felt roof coverings\n\nStress and damage from expansion and contraction on the weathering membrane\n\nCondensation forming at ceiling level, leading to dampness and potential mould growth\n\nBy installing Breather Vents in the waterproofing layers of the roof, this moisture is given a safe escape route, significantly extending the life of your roof and maintaining a healthy internal environment.\n\n\u003ch3\u003ePreparation Before Installation\u003c\/h3\u003e\n\nBefore installation, ensure that the roof surface is clean, stable, and prepared for vent integration. For new roofs, consider the moisture present in screeded concrete decks. Proper placement and sealing of the breather vent will allow effective moisture escape and prevent future roofing complications.\n\n\u003ch3\u003eFAQs\u003c\/h3\u003e \u003ch4\u003e1.
