Roof Windows on Port Talbot Roofs

A roof window sits in the plane of the covering with a flashing kit weathering it in on all four sides, and on slate in the older streets and tile on the estates that kit has to suit the covering it is set into. On these works-built terraces a leak around one is far more often the flashing, the seals or condensation than the window itself having failed.
What This Covers
- Roof-window leaks
- Flashing issues
- Water ingress around roof windows
- Water ingress connected with the affected detail
- Localised weathering or damage requiring repair
Leak or Condensation
These two get confused constantly and they need opposite responses, which under salt and industrial atmosphere together is an expensive thing to get wrong. With the south-westerly straight off the bay, water appearing only in driving rain is a flashing problem. Water appearing on cold still mornings on slate in the older streets and tile on the estates is condensation running off the glass, and no amount of sealant outside will change it.
Checking It Properly

A roof window can be inspected from inside and out, which on these works-built terraces makes diagnosis easier than most roof leaks. Where access is level near the front and steep behind, the external flashing check still needs somebody on the roof to see whether the apron and soakers are sitting as they should.
Flashing Kits, Seals and Replacement
A failed flashing kit is replaced with the correct kit for that window and that covering, and on slate in the older streets and tile on the estates using the right profile for slate or tile is what makes it weather. Perished gaskets can be renewed on most units, and where a frame has rotted or a unit misted, replacement is the honest answer — particularly given metal fixings corrode faster here than anywhere on the list.
