Poor Ventilation Causes Condensation and Timber Rot
A roof space without adequate ventilation traps warm, moist air rising from the rooms below. In cold weather, this moisture condenses on the underside of the roof deck, on rafters and on any cold surface. Over time, persistent condensation leads to wet insulation, timber rot, mould growth and staining on ceilings. Many homeowners mistake condensation damage for a roof leak, but the cause is actually insufficient airflow.
Radiant Roofing installs roof ventilation products across Kent, Sussex and Surrey. We fit tile vents, ridge vents, soffit vents and mechanical ventilation units to ensure your roof space has the correct airflow to prevent condensation. We calculate the ventilation requirement based on your roof size and type, and install the right combination of products to meet Building Regulations.

Frequently Asked Questions
Roof ventilation typically costs between £100 and £800. A few tile vents to address a localised condensation issue cost £100 to £300. A full ventilation solution with ridge vents and soffit vents runs £400 to £800. We assess your specific needs and provide a fixed quote.
Signs of poor ventilation include condensation on the underside of the roof felt, damp or wet insulation, mould on roof timbers, musty smells in the loft and staining on upstairs ceilings. If you see any of these, your roof space almost certainly needs better airflow.
Tile vents are individual units that replace a single tile and provide ventilation at specific points on the roof slope. Ridge vents run along the ridge and provide continuous high-level ventilation. The best solution often uses both — soffit vents at the eaves for air intake and ridge vents at the top for extract.
We cover Kent, East Sussex, West Sussex and Surrey. Our teams regularly install roof ventilation in Tunbridge Wells, Crowborough, Sevenoaks, Tonbridge, Uckfield, Haywards Heath, East Grinstead and surrounding areas.
