Bespoke Lead Flashing Kits

Bespoke Lead Flashing

A rooflight is only ever as good as the detail that surrounds it.

While the frame and glazing define performance, it is the flashing that determines how successfully the rooflight is integrated into the fabric of the building. Poorly executed detailing can compromise both appearance and weathering. Done properly, it becomes almost invisible, allowing the rooflight to sit naturally within the roof.

For this reason, Stella Rooflight offers bespoke lead flashing kits, designed specifically for each rooflight we manufacture.

Designed as Part of the Rooflight - Not an Afterthought

Every Stella flashing kit is made to order alongside the rooflight itself. It is not a generic add on or a standardised solution.

Each kit is carefully prepared to suit the exact dimensions of the rooflight, the pitch of the roof, and the roofing material. Where slate is used, particular attention is given to slate size and coursing, including diminishing slates where required. The result is a set of components that align precisely on site, allowing the rooflight to be installed cleanly and correctly, without compromise.

This level of consideration ensures that the detailing feels resolved from the outset, rather than adapted during installation.

Prepared for Traditional Installation

Stella flashing kits are designed to support established roofing practices, not replace them.

All elements are formed in lead using traditional methods, allowing experienced roofers to install the rooflight in a way that is entirely consistent with heritage and conservation requirements. The difference is that the key components are already accurately prepared, reducing the need for time consuming cutting and shaping on site.

This approach improves consistency across the installation and helps achieve a more refined final result.

A More Efficient Process on Site

By preparing the flashing components in advance, Stella reduces the level of on site fabrication required.

Installers are not starting from raw materials. Instead, they are working with elements that have already been cut and formed to suit the specific rooflight and roof covering. This not only saves time, but also reduces the risk of inconsistency and unnecessary waste.

For projects with multiple rooflights, this consistency becomes particularly valuable, ensuring that each installation is carried out to the same standard.

Suitable for Slate and Tile Roofs

Each flashing kit is tailored to the specific roof covering.

On slate roofs, the detailing is carefully considered to integrate with the coursing, ensuring that soakers sit naturally within the build up of the roof. On tiled roofs, the flashing is prepared to suit the profile and spacing of the tiles, maintaining both performance and visual balance.

This level of adjustment is what allows the rooflight to feel properly embedded within the roof, rather than applied to it.

Part of a Complete Stella Rooflight

The lead flashing kit forms part of a wider, fully considered system.

Alongside the stainless steel rooflight, hardwood internal liner and high performance glazing, it ensures that every element, both visible and concealed, has been designed to work together.

Nothing is left to chance, and nothing is left to be improvised on site.

FAQs
What is a bespoke lead flashing kit for a rooflight?
A bespoke lead flashing kit is a set of pre-prepared lead components designed specifically to weatherproof a rooflight where it meets the roof covering. Unlike standard flashing, a bespoke kit is made to suit the exact size of the rooflight, the roof pitch, and the type of roofing material, ensuring a precise fit and reliable long-term performance.
Why is lead used for rooflight flashing instead of other materials?
Lead is widely regarded as the best material for rooflight flashing because of its durability, flexibility and longevity. It can last over 100 years when installed correctly, withstands harsh weather conditions, and can be shaped to form watertight seals around complex roof details. Alternatives such as aluminium or plastic typically have a much shorter lifespan and are less suited to traditional or conservation projects.
Are Stella Rooflight flashing kits made to measure?
Yes, every Stella Rooflight lead flashing kit is made to measure. Each kit is designed alongside the rooflight itself, taking into account the exact dimensions, roof pitch and roofing material. This ensures that all components align correctly during installation and eliminates the need for on-site modification.
What is included in a bespoke lead flashing kit?
A typical bespoke lead flashing kit includes a pre-cut lead apron for the cill, a formed back gutter at the head of the rooflight, and individually prepared lead soakers for the sides. These components are designed to work together as a complete system, allowing the rooflight to be integrated into the roof using traditional leadwork techniques.
Do bespoke flashing kits make installation easier?
Yes, bespoke flashing kits significantly simplify the installation process. Because the lead components are already cut and formed to suit the rooflight and roof covering, installers spend less time shaping materials on site. This reduces installation time, improves accuracy and helps achieve a more consistent and professional finish.
Can lead flashing kits be used on both slate and tile roofs?
Bespoke lead flashing kits can be designed for both slate and tile roofs. For slate roofs, the flashing is tailored to match the slate size and coursing, including diminishing slates where applicable. For tiled roofs, the flashing is prepared to suit the tile profile and spacing, ensuring proper integration and weatherproofing.
What information is needed to design a bespoke flashing kit?
To design a bespoke lead flashing kit, key information includes the size of the rooflight, the type of roof covering (such as slate or tile), the roof pitch, and if applicable, the slate dimensions. This allows the flashing to be accurately prepared so that it fits seamlessly with the roof construction.
Are lead flashing kits suitable for conservation and listed buildings?
Yes, lead flashing kits are particularly well suited to conservation and listed building projects. Lead is a traditional roofing material that is widely accepted by conservation officers, and bespoke kits allow rooflights to be installed in a way that respects the character and detailing of historic buildings.
How long does lead flashing last on a rooflight?
When correctly specified and installed, lead flashing can last well over 100 years. Its durability and resistance to weathering make it one of the most reliable materials available for roof detailing, particularly in exposed environments such as the UK.
Is a bespoke flashing kit necessary or can roofers create flashing on site?
While experienced roofers can form flashing on site, a bespoke flashing kit ensures greater accuracy, consistency and efficiency. It removes guesswork, reduces material waste and helps ensure that the rooflight is installed exactly as intended. For high-quality or design-led projects, a bespoke solution provides a more reliable and refined result.
