Do you need a Price?

So you’ve decided to install a rooflight in your home, but have you considered how to fit it?

Preparation is key. One wrong move could prove costly so you should plan how to carry out the job before making a start. If you follow the instructions below, it should be relatively easy.

Who Should Install It?

There are two options when it comes to fitting your rooflight: you can hire a contractor to install it for you, or roll up your sleeves and get started.

If you decide to go with the latter, it’s essential to familiarise yourself with the process first. That way you can be confident with the job at hand and with the end result. Download our installation guides here.

However, unless you’re a trained builder or have years of DIY experience, we would recommend seeking the expertise of a contractor, even if it’s purely for consultation.

What Equipment Is Supplied?

This all depends on the manufacturer and style that you go for. However, if you choose to buy your rooflight from EOS, the following equipment will be supplied:

With an upstand

  • One upstand
  • One glass lid
  • Two security screws
  • Six standard screws
  • Four flashing

If you decide to hire a contractor, they should be able to supply the following equipment, but otherwise you need to invest in it:

  • Roof membrane
  • Four arris rails
  • Six to eight brackets
  • Two timber wedges – if your roof’s pitch is below 3º

Without an upstand

  • One glass lid
  • Two security screws
  • Six standard screws
  • Four flashing
  • Eight gaskets

You will also need:

  • Materials to construct an upstand
  • Roof membrane
  • Four arris rails
  • Six to eight brackets
  • Two timber wedges – if your roof’s pitch is below 3º

Tools Needed

Stanley knife, level and elctric drillYour rooflight will come with all the necessary materials but not the tools required for installation. If you don’t already have the following tools, we would recommend hiring or investing in them.

  • Power drill
  • Stanley knife
  • Spirit level

If in any doubt as to the right tool to go for, seek the assistance of your supplier or local hardware store.


Before installing your rooflight, ensure that the areas surrounding it are clean and clear of debris. Any roof joists and decking should be secured fastened down and you need to check that you have enough manpower to safely lift and install your rooflight.

Step 1
Remove all of the packaging and check that you have all the parts required. Then place the lid on a flat surface to avoid damage. If your rooflight has an upstand, be sure to put this out of the way of the lid to reduce the risk of breakage.

Step 2
Place the upstand over the opening in your roof. Check that the pitch of the upstand is between 3 and 15 degrees using a spirit level. If it is any less than 3 degrees, water will simply sit on the glass.

Step 3
Fit the upstand using the brackets provided and secure it using the arris rails.

Step 4
Now you need to weatherproof the upstand using the membrane. Once this is completed you will need to fit the flashings to the upstand.

Step 5
Place the rooflight lid over the upstand to check that it will fit securely. Then secure the lid using the safety screws provided. Next, use the remaining screws to securely fit the unit in place.

And there you go; it’s as easy as that. Remember that if you get stuck at any point you should contact your supplier or contractor for advice and assistance.

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.

Excellent product with a very high finish. EOS were very helpful and we are delighted with the rooflight we ordered. Our room looks amazing now we have so much light flooding in to it. We looked at lots of suppliers but we are glad we chose EOS on recommendation from our builder who had used them before.

The service provided by EOS Rooflights was absolutely outstanding. From the communication via e-mail and telephone, to the quality of the product, I could not fault them one bit. We have now had our rooflights fitted and they look amazing! The joiner said the instructions were easy to follow and the rooflights themselves were easy to fit. Amazing!

We met EOS at the Homebuild Show in Birmingham as we wanted to see the rooflights before we bought them for our extension. We met with Elliot who answered all of our questions and helped out with our plans, as one of the sizes needed amending. The rooflights look beautiful in our kitchen. I would highly recommend EOS to anyone, especially if you this is your first build. Elliot couldn't of been more helpful with answering our queries.
