Velux install from inside

[RichA]

Is it standard to install a velux from the inside? The contractor is recommending a tower which is presumably adding significantly to the cost.

Supply and erect tower
Supply Velux MK04 roof window & flashing kit
Remove insulation and roof tiles, trim opening, alter insulation and reboard
Install roof window including roof tiling and installation of flashings
Supply tile fittings (eaves and gables)
Remove tower​

The towers to tile it too.

Are these not installed from through the window?

Would the tower be inside? How high is the window...

 

[RichA]

Inside it is 1500mm from floor (on 2nd floor)

How are they going to remove the tiles from the inside?

 

[SpecialK]

I did two about 20 years ago from the inside, assume its still do-able?

Get some more quotes or go back to the builder for an explanation?

I believe you break-through one tile, and then have access to remove the remainder.

I did mine entirely from the inside, 25 years ago. Lift one tile up, bring it inside, rinse and repeat until enough tiles have been removed for window, plus a few. Cut and reinforce roof timbers, insert window, fix, then flashing. Finally reinstall tiles close up to flashing. Most difficult part, is lifting the window into place they can be heavy.

Yes, but easy enough to tease them loose, not all will be fixed down. My roof as a minimum three tile depth throughout.

And maybe ask about his RAMS? (Risk Assessment and Method Statement)

These days every tile is nailed in, mine certainly are.

If it makes a difference, my roof is a mid 1950's and despite being in a quiet exposed location, I have never had a tile come off.
