Do you need a Price?

If you are adding a skylight to a flat roof, you must decide on whether to construct your own upstand or purchase one from your rooflight supplier.

An Upstand or Kerb is what keeps the rooflight off of the roof’s surface, and is required by building regulations for safety and weathering reasons. The upstand must protrude at least 150mm above the roof and a recommended minimum pitch of at least 3 degrees.

Should I make my own upstand?

There are advantages to both making your own and purchasing via your supplier.

Cost is generally the main reason people choose to make their own. A simple upstand can be constructed from excess timber on site minimising waste or using standard timbers found at any local wood supplier. Creating your own upstand also allows your to weather your roof without the rooflight being on site protecting it from any potential damage.

walk on cross sectionA purpose manufactured upstand benefits from improved thermal performance, weathering and air tightness. The profile has been designed and engineered to fit your exact rooflight  giving you peace of mind that your skylight is going to fit perfectly.

Our Opening Hinged Rooflight, Tripple Glazed Rooflight and Access Rooflights are all supplied with an insulated timber upstand as standard. If you are purchasing a Fixed Rooflight from us, we can provide this as an optional extra.

If you would like to build your own upstand, you can use this guide or visit our technical downloads page for specific measurements.

Looking For An Easier Way?

The easiest way to ensure your rooflight is installed correctly is to purchase a made to measure insulated upstand from your rooflight supplier. At EOS Rooflights all of our stock products are available as lid only or with optional upstand.

How do i create my own upstand?

There will be lots of ways to make an upstand but we will give a quick guide to the most basic option and also show the recommended way of creating your upstand, we will not show a step by step guide as this should be done by someone with more advanced carpentry skills.

Please Note: We only recommend attempting to build this yourself if you are confident in basic carpentry.

Basic Upstand Guide

We are basing this upstand to suit our EOS rooflights – fixed (lid only). Different systems will have slightly different requirements (upstand width and frame details) so make sure to study the relevant technical drawings.

Stanley knife, level and elctric drill

Equipment Required:

  • Drill
  • Stanley Knife
  • Spirit Level

Plus:

  • Screws to fix timber pieces together. These will need to be long enough to affix two pieces of 47mm each.
  • 8 Gaskets

Materials Required:

  • Timber – 47mm (width) by 150mm (height). The total length will need to cover the dimensions of your roof light twice, plus an excess of 752mm (we’ll explain why later!).

Example:

If you have an EOS F3 (1000mm x 1500mm) unit which is 1000mm in length (A and B in the above image), and 1500mm wide (C and D), the total length of timber you will need is:

(A+B+C+D) x 2 + 752mm = 10,752mm (just under 11 metres)

You Might Also Need:

  • Furring strips – these will be useful if you need to pack the upstand to reach the required minimum 3 degree drop.

Cutting Timber Lengths:

The first step to putting together the upstand is to cut the timber to the correct size.

  • The timber kerb will need to be 84mm – 94mm in depth, this is easily achieved by screwing 2 lengths of timber together (e.g 2 x 47mm timbers = 94mm)

Width

  • Cut four lengths of timber at A and B length, plus 188mm per piece (this is where the stray 752mm comes in – 188mm x 4 = 752mm). In the given example (EOS F3), this would mean cutting four pieces that are 1188mm each.

Length

  • Cut four lengths of timber at C and D length, E.G. An EOS F3 Rooflight, requires four pieces at 1500mm each.

Preparing For The Build:

The upstand will need to be completely flat, so be certain that the wood is also sanded so that it is level and stands at a minimum of 150mm.

You might wish to check each piece using your spirit level.

Putting The Frame Together:

  • Fix the matching lengths of timber along the long side. This will create four pieces that are 94mm in width, maintaining the 150mm height.
  • Next, fix all the timber pieces together to make a box shape. This should make the inside edge of your upstand the same dimensions as the structural roof opening. Ensure the frame is square by measuring corner to corner.

Checking The Pitch:

Now that you have constructed your upstand, you need to ensure that there is at least a 3 degree drop on the roof light (at least 5mm over every metre). The maximum pitch of our roof lights is 15 degrees.

Check this using the spirit level, and if it is below 3 degrees, you will need to pack the space using furrings.

Ready For Use:

You are now ready to position and fix the upstand over the structural opening. Before doing so, be sure to measure diagonally across the opening and adjust accordingly to check that the upstand is square in line.

Once ready to affix the skylight unit, you will need to refer to your individual product’s installation guide. You can find a Fixed installation guide here.

Recommended Upstand Detail

The more advanced detail is the equivalent of creating a mini stud wall. The purpose of this is being able to insulate the inner cavity which gives greater thermal performance and sound insulation. We will not give a step by step guide but you can find some resources to assist you creating this.

All contact with EOS was dealt with efficiently and by friendly staff. The quality of the rooflight is excellent. In a different league to the alternatives I have seen. A couple of points to improve on below, however these do not detract from how the quality of the roof light lifts the whole build..... - Rooflight did not arrive on the advised date, arriving the following morning instead. This required a number of builders to return the following day to lift off the van. - Do not underestimate the weight. Very challenging for my builder just to get off the box van. - The ordering instructions make it clear to provide the size of the hole. That will then equate to clear glass when fitted. However on arrival length and width of clear glass were both 3cm shorter than ordered. This was explained by phone as relating to the rebate for plaster board, however this should be made clearer ahead of ordering as we could have ordered 3cm larger to get the clear glass size originally envisaged.

Their customer service was good. I was able to speak with someone quickly and easily by telephone or email to clarify points before I ordered my items. The ordering process was very easy and the items were delivered on time. Upon delivery there was a scratch on one of my rooflights. I contacted EOS immediately and they were happy to send a repair kit to me, free of charge, which arrived in the post within a few days of me speaking with them. I'm very pleased with the service I've received and the product looks great in my new extension!

Swift. Delivery. Arrived as described. Straight forward payment arrangement. Great advice and support when planning project. Motorised rooflight works remarkably quietly. A little costly however compared to some competition.

I actually bought my roof lights on the back of EOS’s reviews section, and now my extension is nearing completion, (finally) I wanted to pass on my experience. I couldn’t be happier with my decision, its clearly a very high quality product and they look amazing in our new kitchen. They are heavy so make sure you have lots of strong guys on site. The staff are all very helpful and seem very knowledgable. Highly recommended them.

Excellent customer service. Really took the time to listen to our needs and help us find exactly what we wanted, within the time schedule from our builders. They were also flexible as the schedule shifted and always available for any questions. And beyond that, our roof lights look so amazing! So, I'm a very happy customer.

EOS were very helpful during the sales process, liaising directly with my builder to confirm requirements (when I was way out of my depth). My builder’s feedback post installation is that the windows are heavy duty and top quality, even when compared with more expensive options he’s fitted in the past. He’ll be recommending EOS for future builds.
