Location – Winchmore Hill, London

While the sun is still out, we were called in to replace a very old roof window.  The pre-existing roof window had broken hinges and rotting timber.  The window would not even close and was letting in a terrible draft.

The new VELUX we are installing is a GGL U08 3059.  This is a size of 1340mm x 1400mm, so its a big window.

No time to waste, time to get to work…

As you can see from images below, the pre-existing skylight was in a terrible state.

As you can see, this skylight had to be changed, there was no chance of repair, let’s also have a look from the outside.

So we get to work, stripping the tiles off of the roof.  We then remove the window sash from the frame

We then remove the frame from the roof

We then ensure the opening is all neat and tidy and ready for the velux skylight.  We then get the velux out of the box and prepare it for installation

We take the window sash out of the velux skylight and take the frame up to the loft, ready for installation.

The frame is installed.  We now need to apply the flashing kit around the velux skylight

Once the flashing kit is in place, it is time to re-tile around the skylight

Ok tiling is done and looks great

All we have to do now is to install the sash
