Few things are more misunderstood about the home than roof ventilation. With winter approaching, saving on energy costs and preventing winter damage to roofs are high priorities for owners.

A proper roof ventilation may help reduce many of the costs and dangers attributed to winter weather. Even in summer: without proper ventilation, heat can rise into the attic and cause moisture build up. That is the reason why some degree of roof ventilation is always a good idea.

Slate vents are by far the easiest professional solution to roof ventilation problems. They are super easy to fit either for new roofs or renovating an existing one.

It’s said that one of the best places to fit slate roof vents is normally the bottom third of a roof just above insulation level. This allows air to circulate over the insulation taking away any moisture evaporating upwards. Positioning a vent too low in the insulation may create cold spots resulting in condensation dripping back onto the insulation or ceiling below.


It depends on the house, the location, the weather… but for most situations a simple 2 vents front and back seems to be a good starting point. Some roofers recommend two low and one high per elevation, making a total of 3 front and 3 back.
