Southsea's loft conversion Velux installations face the most aggressive coastal conditions of any Portsmouth suburb. We use BDX copper flashing as standard here — zinc is inadequate in direct Channel salt air. Common Velux failures in Southsea include flashing kit corrosion from salt air, failed dome seals on older units, and condensation between panes indicating failed sealed units. We carry parts for the most common Velux sizes and can carry out same-day repairs on most units.
Standard Velux flashing kits are rated for inland use. For Southsea properties we specify the BDX copper flashing kit or equivalent coastal-grade alternative on new installations and replacements — the salt air environment in this area will corrode standard zinc flashing significantly faster than the inland design life assumes.
We install new Velux windows as part of loft conversion roofing work across Southsea. Full structural assessment, correct flashing specification for coastal conditions, and building regulations compliance certificate provided on completion.
