SPECIFICATIONS

Pitched Roof Skylight / Rooflight 1200 x 2500 mm

Our pitched roof skylights are manufactured to the highest standard making them frameless from the inside and out. They are easily installed with lead flashing, that’s cut on-site that is suitable for all roofs. As they are frameless internally they let in more light.

This high-performance, non-opening frameless skylight is triple glazed with 6mm toughened, self-cleaning glass and a U Value of only 0.9 W/m²K. The internal quoted glass size is 1200 x 2500 mm, see the structural diagram below.

When purchasing a pitched roof skylight for a tiled roof from us it is very simple.

All our skylights come triple-glazed as standard and have solar protection.

The upstand is formed with the same opening as you can see in our drawings.

All you need to add is the flashing of your choice in our accessories section.

The flashing is then wrapped around your upstand sealing the upstand to your roof tiles.

Make sure you have added the right amount of flashing, the full circumference of your skylight will require flashing.

Our rolls come in 7.5-meter lengths. Let’s say you have bought a 1000 x 2000mm skylight you then require a total of 6 meters as you have 2x 1 meter sides and 2x 2 meters becoming a total of six lineal meters therefore one roll of flashing will be required.

  1. Mia Evans –

    I’ve been a roofer for over 20 years and Saris Extension’s skylights are among the best I’ve ever installed. They’re high quality, energy efficient, and visually stunning.

  2. Edward Remington –

    The sleek design of my frameless skylight from Saris Extension is a complete showstopper. It fits perfectly with my pitched roof, creating a stunning visual effect that has made my home the envy of my friends.

Our own drivers deliver within London (M25) in order to guarantee the safe arrival of all our products.

Please be aware that as our drivers are alone and pre-loaded in our warehouse, we will require you or your builders to be on-site for the acceptance of all orders.

For orders outside M25, we use an external shipping network. Once sent, they will call you to book a suitable date and time for delivery. 

The Extra Economy Shipping options work for all areas, except Northern Ireland and Scotland.

 Some of these companies may not have the correct vans in place and might not be able to deliver to your door, so we might have to ask you to pick it up from the local depot (usually within 20 min drive) however this is rare.  

Most of our products weigh a considerable amount varying from 10kg to 280kg, therefore it may need more than two, four, or even six people to unload depending on the size and weight of your product.

We will not accept liability for any broken skylights during the unloading process, as it is down to the customer to organise this process.

In the event that the customer does not attend the delivery appointment or no one is there to accept your product, we will try and contact you via phone, text, and voicemail before our driver leaves your delivery address.

If no contact is made, we will have no option but to return your product to our warehouse.

INSTALLATION GUIDE

How to Install our Skylights on Pitched Roof

Through the years we have seen mistakes and poor practices in Skylight installations, which lead to many issues in the following months and years.

We feel obligated to share our experience and knowledge with you to avoid these issues. That's why we have prepared a detailed “Step-by-Step Installation Guide” for a professional Skylight installation.

We can, and do guarantee the quality of the glazing unit itself, but we can't take responsibility for the installation, it falls on the builder/fitter's shoulders.

You are not required to fully comply with our guidance below, however, we recommend you to follow it as fully as possible.

Step-by-Step

INSTALLATION GUIDE

Structural opening - provided By builder

Bear in mind our Skylights sizes are the sizes of the bottom (internal) glass panel. The top panel is stepped by 100mm on each side, and the overall externally visible size is 200mm bigger in both directions:

For example, only in this guide will we present installation sketches for a Skylight 600mm x 600 mm. For all other sizes, we provide installation sketches in the gallery of each size separately.

DOUBLE/TRIPLE GLAZED SKYLIGHT 600x600mm has the following sizes:

The upstand should protrude a minimum of 150mm above the roof level.

A minimum pitch of 6 degrees relative to the horizon must be provided to avoid water pooling in the middle of the glass panel (for every meter of Skylight a 10cm fall is required). It is worth spending a few extra minutes before applying the silicone to run a water test to ensure the water is not pooling (even though you are installing glass it will still bend in the middle)

Upstand opening should allow for 5mm tolerance on each side:

The internal distance upstand to upstand needs to be 10mm bigger than the quoted skylight size (in our example: 610mm by 610mm)

Skylight Support - provided By builder

The Skylight support is a 25x50mm (2”x1”) timber:

Install the support in such a way that the top of support is as follows:

-Triple Glazed Skylight            - 42mm below the top of upstand

Weather the upstand

Apply the roof covering material to cover the external face and top of the upstand:

Once you finish weathering the upstand, you are ready to install the Skylight.

Make sure all surfaces where the silicone will be applied are clean of dirt, dust, moisture, etc.

  1. Apply the foam rope on top of the 2”x1” timber support to level off any discrepancies which will prevent any pressure and stop cracking on the bottom glass laminated pane. THE WARRANTY WILL BE VOID IF A FOAM ROPE IS NOT USED.
  2. Apply, generously, on top of the upstand weatherproof sealant, usually, 1 tube is enough for 6 linear meters.
  3. Lower the skylight with suction cups, and make sure you check the load on each cup.
  4. Apply waterproof sealant on the underside of the overhang and smooth it over once more to make sure it is watertight.

For a pitched roof please follow the technical diagram below:

Skylight installation on pitched roof

* With regards to the silicones we recommend the following products:

  • Black weather silicone - DOWSIL 791 Weatherproofing Sealant

DO NOT USE ACRYLIC SEALANTS!

Be careful what silicones you are using to install and weather tight your Skylight. We recommend the above products as fully compatible with our glazing unit silicones.

A chemical incompatibility between silicones used in manufacturing the glazing unit and installing it can lead to discoloration and/or loss of adhesion to the substrate. This means possible depressurization of the glazing unit (allowing moisture to penetrate inside the glazing unit and internal condense), not sufficient bonding to the support structure, and poor weather tightness (possible leaks).

THE WARRANTY WILL BE VOID IF A FOAM ROPE IS NOT USED AND NOT PURCHASED FROM US.
