A well-installed roof window transforms a dark loft into a bright, ventilated living space. Poorly fitted, it becomes a source of leaks, condensation and heat loss. TOIT DES DÔMES installs and repairs all types of roof windows — Velux, Fakro, Roto — on tiles, slates and zinc. Every installation includes the full flashing kit (apron, skirt, collar) and is backed by a 10-year warranty.
Velux roof window installation in Clermont‑Ferrand costs between €800 and €1,800 (supply + fit). Leak repair from €200. Free estimate — fast response across Puy‑de‑Dôme.
Clear and transparent guidance, from your first call to project completion.
We evaluate your roof pitch, covering type and sun exposure to recommend the most suitable format and model. We also check local planning rules if your property is in a protected zone.
We remove tiles or slates around the future opening, cut the boarding and adapt the framework if needed. The opening is cut to millimetre precision for the chosen Velux frame.
The frame is secured to the framework. The full flashing kit (zinc apron, skirt, collar) is installed for a perfect seal around the entire window perimeter.
Tiles are carefully replaced around the window. The interior is sealed. We test opening, closing and weathertightness. You receive the Velux documentation and 10-year warranty.
Velux is the global reference for roof windows with over 80 years of expertise. Their products are built to withstand the most severe weather — wind, rain, snow — while delivering superior thermal and acoustic insulation. In Auvergne, where winters are harsh and summers hot, a well-sized Velux brings natural light and ventilation without compromising insulation.
A 78 × 98 cm Velux roof window brings as much natural light as three standard wall windows. Triple Pane ranges achieve a Uw coefficient of 1.0 W/m²K, well below RE2020 requirements. Electric or solar-powered models integrate with home automation and enable automatic ventilation on hot days.
A well-maintained Velux lasts over 30 years, but peripheral seals and opening mechanisms can degrade after 10 to 15 years. A detached seal or damaged zinc flashing causes leaks visible as damp patches on the ceiling or walls around the window. These must be addressed quickly to prevent damage to the insulation and framework.
We work on all roof window brands: Velux, Fakro, Roto, Rooflite. Depending on the condition, we replace the seal, redo the zinc flashing, or — if the frame is too degraded — replace the whole unit with a new window. Free diagnosis.
