Eaves ventilation is a simple and effective way of providing the necessary air movement within a cold roof. It is most effective when used in conjunction with high level roof ventilation, provided by Corovent slate, tile and ridge vents,
as it utilises the natural thermal uplift in a roof void. The Building Regulations demand eaves ventilation in most cold roofs and often high level ventilation as well. Appendix 1, Roof Ventilation and the Building Regulations provides basic guidance on the ventilation requirements for different roof types.
