flat roof overhang purpose

[Larry1990]

Hi folks,

I had a query around flat roof overhangs on garden offices/rooms please if anyone can enlighten me?

I found on Google they can provide shade in South facing gardens, but other than this does the small overhang on garden rooms serve any purpose or is it purely a matter of aesthetics? Does it aid in venting a cold roof? I saw some videos where they vent through the sofit of the overhang.

Cheers

Its going to depend on what you want it to do!

Does not provide meaningful shade unless the overhang is over 600mm (why shade a wall anyway? )

Does nothing for ventilation.

It protects the wall from rain and staining

Thanks woody and catlad. I'm not after it doing anything if I can get away with it. It'll make the build a little simpler and use a bit less materials so a win for me. Pretty much every video seems to have an overhang so I just wanted to make sure I'm not missing a trick by not having an overhang.

Cheers

You'll have a white stained mess of a wall if you don't.

You can't even manage a 50mm overhang?

Thanks Woody, yes I will now! That's the trick I was missing right there. Cheers appreciate that.

A reasonable overhang may be useful when its raining and your looking for your keys!
