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.

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!
