How Attic Baffles Benefit Your Roof And Home
- Less Mould and Mildew – Moisture can build up in the attic even with a well-sealed roof. It can build up to the point that mould and mildew spores find an ideal environment to grow if it isn’t removed through ventilation. Mould and mildew eat organic materials like timber rafters and/or a roof deck that support your roof. Over time, they can cause enough damage to the roof to weaken the rafters and/or roof deck.
- Fewer Ice Dams – Ice dams develop when snow and ice on the roof that is higher up melts, rolls down the roof and then refreezes when it flows over the soffit area, which is not heated by the heat of the house. Your roof and eaves troughs may be harmed by ice dams. Ice dams are less likely to form in the attic thanks to good ventilation made possible by baffles that maintain a more constant temperature.
- A Cozier Home – Your home will be warmer in the winter and cooler in the summer if your attic is properly aired, which will improve the effectiveness of the attic insulation.
