All our Roof Lanterns come with an excellent 10-year guarantee<\/figcaption><\/figure>\n\n\n\n What is a Roof Lantern Upstand?<\/h2>\n\n\n\n
A roof lantern upstand is a crucial structural feature that supports the roof lantern itself. Essentially, it\u2019s a raised frame or kerb that your roof lantern sits on. <\/p>\n\n\n\n
The upstand ensures that the roof lantern is elevated above the roof surface, providing the necessary clearance to prevent water ingress and allowing for proper sealing. <\/p>\n\n\n\n
Without a properly constructed upstand, your roof lantern could be at risk of leaks, poor insulation, and other issues.<\/p>\n\n\n\n
The upstand serves multiple purposes:<\/p>\n\n\n\n
- \n
- Waterproofing<\/strong>: By raising the roof lantern, the upstand helps to prevent water from pooling around the edges, which is vital in maintaining the watertight integrity of your roof.<\/li>\n<\/ul>\n\n\n\n
- \n
- Insulation<\/strong>: The upstand creates a barrier between the roof surface and the interior, improving thermal efficiency.<\/li>\n<\/ul>\n\n\n\n
- \n
- Structural Support<\/strong>: It provides a secure base for the roof lantern, distributing the weight evenly and ensuring stability.<\/li>\n<\/ul>\n\n\n\n
Requirements for Flat Roof Lantern Upstands<\/h2>\n\n\n\n
Installing a roof lantern on a flat roof requires careful consideration of the upstand details to ensure everything functions correctly. <\/p>\n\n\n\n
The upstand must be constructed to a certain height, which is typically specified by building regulations. <\/p>\n\n\n\n
This height ensures that the roof lantern is raised sufficiently above the roof level to allow for proper drainage and prevent water ingress.<\/p>\n\n\n\n
Key Requirements:<\/strong><\/p>\n\n\n\n
- \n
- Height<\/strong>: The upstand height typically ranges between 150mm and 200mm, though this can vary depending on specific building regulations and the type of roof lantern.<\/li>\n<\/ul>\n\n\n\n
- \n
- Material<\/strong>: The upstand should be made from durable materials that can withstand the elements. Common materials include treated timber or pre-formed metal, which are then insulated and waterproofed.<\/li>\n<\/ul>\n\n\n\n
- \n
- Insulation<\/strong>: Insulating the upstand is crucial to prevent heat loss and condensation issues. The insulation should be continuous with the roof to maintain thermal performance. <\/li>\n<\/ul>\n\n\n\n
- \n
- Waterproofing<\/strong>: The upstand must be properly sealed with a waterproof membrane to protect against leaks. This membrane should be extended up the sides of the upstand and securely sealed around the edges of the roof lantern.<\/li>\n<\/ul>\n\n\n\n

Typical Section Through Flat Roof<\/h2>\n\n\n\n
When installing a roof lantern, understanding a typical section through a flat roof can help you visualise how the upstand integrates with the rest of the roofing system.<\/p>\n\n\n\n
Here\u2019s a breakdown of what you might expect to see in a cross-section:<\/p>\n\n\n\n
- \n
- Roof Deck<\/strong>: The base layer of your flat roof, typically made of plywood or OSB (Oriented Strand Board).<\/li>\n<\/ul>\n\n\n\n
- \n
- Vapour Control Layer<\/strong>: This layer prevents moisture from penetrating the insulation and causing damage.<\/li>\n<\/ul>\n\n\n\n
- \n
- Insulation Layer<\/strong>: Provides thermal efficiency, reducing heat loss from your home.<\/li>\n<\/ul>\n\n\n\n
- \n
- Waterproofing Membrane<\/strong>: Protects the roof from water ingress, typically made from materials like EPDM, TPO, or bitumen.<\/li>\n<\/ul>\n\n\n\n
- \n
- Upstand<\/strong>: A raised kerb constructed from timber or metal, insulated and sealed with a waterproof membrane.<\/li>\n<\/ul>\n\n\n\n
- \n
- Roof Lantern<\/strong>: Sits atop the upstand, securely fastened and sealed to prevent leaks.<\/li>\n<\/ul>\n\n\n\n
Each of these elements works together to create a roof system that is both functional and durable, ensuring your roof lantern performs optimally.<\/p>\n\n\n\n
Materials and Work to Be Carried Out by Others<\/h2>\n\n\n\n
When installing a roof lantern, several materials and tasks will typically be handled by other trades or contractors. Understanding these can help you manage your project more effectively.<\/p>\n\n\n\n
Preparing the Roof<\/h3>\n\n\n\n
To prepare your roof for a roof lantern upstand, first a hole needs to be cut into either an existing flat roof, or during the construction of a new flat roof extension<\/a>.<\/p>\n\n\n\n
Upstand Construction <\/h3>\n\n\n\n
This might be handled by a carpenter or roofer, depending on the materials used.<\/p>\n\n\n\n
Although metal can be used for the construction of the upstand, the most common and cost-effective material used is timber. <\/p>\n\n\n\n
Insulation Installation <\/h3>\n\n\n\n
Often a rigid board or spray foam, that is designed to fit snugly within and around the upstand. <\/p>\n\n\n\n
A professional installer ensures that the insulation is fitted correctly, avoiding any thermal bridges.<\/p>\n\n\n\n
Waterproofing <\/h3>\n\n\n\n
Usually applied by a qualified roofer to ensure the upstand is sealed and watertight. This step is crucial to prevent leaks and ensure longevity.<\/p>\n\n\n\n
Roof lantern installation<\/h3>\n\n\n\n
By coordinating with the right professionals, you can ensure that your roof lantern upstand is constructed to the highest standards, providing a solid foundation for your roof lantern to be installed.<\/p>\n\n\n\n

FAQs About Roof Lantern Upstand Details<\/h2>\n\n\n\n
What is the Upstand Height for a Roof Lantern?<\/h3>\n\n\n\n
The upstand height for a roof lantern typically ranges between 150mm and 200mm. <\/p>\n\n\n\n
This height is sufficient to ensure that the roof lantern is raised above the roof surface, providing adequate clearance for drainage and preventing water ingress. <\/p>\n\n\n\n
The exact height can vary depending on local building regulations and the design of the roof lantern.<\/p>\n\n\n\n
What is the Minimum Upstand for a Rooflight?<\/h3>\n\n\n\n
The minimum upstand height for a rooflight, which includes roof lanterns, is generally around 150mm. <\/p>\n\n\n\n
However, this can vary depending on the specific requirements of your roof and the type of rooflight being installed. <\/p>\n\n\n\n
It\u2019s important to check local building regulations and consult with a professional to ensure compliance.<\/p>\n\n\n\n
If you’re considering rooflights, why not check out our Korniche roof light<\/a><\/em> range.<\/p>\n\n\n\n
How to Build a Rooflight Upstand?<\/h3>\n\n\n\n
Building a rooflight upstand involves several key steps:<\/p>\n\n\n\n
- \n
- Construct the Frame<\/strong>: The upstand is typically constructed from treated timber or metal, forming a raised kerb that outlines the rooflight’s base.<\/li>\n\n\n\n
- Insulate<\/strong>: Fit insulation within and around the upstand to ensure thermal efficiency.<\/li>\n\n\n\n
- Apply Waterproofing<\/strong>: A waterproof membrane is applied over the upstand, extending up the sides and securely sealed around the edges to prevent leaks.<\/li>\n\n\n\n
- Install the Rooflight<\/strong>: The rooflight is then placed on top of the upstand, securely fixed, and sealed to ensure a watertight fit.<\/li>\n<\/ol>\n\n\n\n
While this sounds like a straightforward process, we\u2019d recommend hiring a professional to minimise future problems such as roof lantern leaking<\/a>.<\/p>\n\n\n\n
What is the Height of an Upstand in Building Regulations?<\/h3>\n\n\n\n
Building regulations typically require a minimum upstand height of 150mm for rooflights and roof lanterns. <\/p>\n\n\n\n
This height ensures that the rooflight is sufficiently elevated above the roof surface to allow for proper drainage and prevent water ingress. <\/p>\n\n\n\n
However, regulations can vary, so it\u2019s essential to consult local guidelines and ensure your installation complies with the specific requirements for your area.<\/p>\n\n\n\n
