A roof space needs air movement. When insulation blocks the eaves or old felt traps moisture, warm damp air from the house condenses on cold surfaces, which can look like a leak and damage timbers over time.
We assess the roof and install suitable ventilation: eaves vents, over-fascia vents, tile vents and ridge vents.

Roof ventilation: common questions
Does a breathable membrane remove the need for vents?
Not always. It depends on the membrane, the roof and how much moisture the house generates.
Will ventilation make my home colder?
Ventilation is above the insulation, so the living space stays insulated.
Can vents be added during roofline replacement?
Yes, it's an ideal time to add over-fascia or soffit ventilation.
