You will also need:

- Four arris rails

Tools Needed
Your 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
Installation
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. Don’t forget to visit download our installation guides here
