Roof Ventilation

A roof space needs air moving through it. Without enough ventilation, warm, moist air from the house can condense on cold timbers and underlay, which is sometimes mistaken for a leak. We fit tile, ridge, eaves and roof-void ventilation to pitched roofs.

• Tile vents set into the roof slope
• Ridge vents along the top of the roof
• Eaves ventilation at the roof edge
• Roof-void ventilation to move air through the loft

Finding the Cause

• Condensation tends to appear as droplets across the underside of the felt, damp patches spread widely, or black mould on timbers, often worst in cold weather.
• A leak tends to be in one place, follows rain, and often lines up with a fault outside.
• Insulation pushed into the eaves can block airflow; non-breathable felt and sealed loft spaces can make condensation worse.
• Moisture sources in the house, such as bathrooms without extraction, also play a part.

How the Work Is Done

• Tile vents replace standard tiles to let air in or out of the roof space.
• Ridge vents or a vented dry ridge system let air escape along the top of the roof.
• Eaves ventilation lets air in at the roof edge, kept clear of the insulation.
• Ventilation work is planned to suit how the roof is built and insulated.

Repair or Replace?

Ventilation can often be added to an existing roof. Where the felt or covering is being replaced anyway, ventilation is best designed in at the same time.
