Slate Roof - pitch

[Raggie]

Hi,

Can anyone advice if there are any design constraints on the maximium pitch of a slate roof.

Anything in building regulation?

We have a very steep and high slate roof, which means in every snow fall we get a substantial weight of snow in te guttering causing the guttering to fail.

I am fighting the builder with regards the guttering is an incorrect design for the pitch of the roof.

If any one can point me at standards or regulations it would be appreciated.
Thanks

You can do vertical slating!

Vertical tiling does not a roof make.. Lol.

If vertical I wouldn't have a build up of snow...and no problem lol.

The roof is probably 15deg off the vertical (need to do some better Calcs to prove that figure), 6m wide at bottom, 9m wide at top, and 12-15m in height

The point I was making was that you can do any pitch from about 17.5° up to vertical. You can slate a roof that's 75°. Surely snow isn't gonna collect on a 75° pitch anyway?

Thanks.

Because of the design of roof, where each side of the roof has what an best be described as "walls" so the roof is recessed between these walls, with guttering at the base means snow collects in an abundance.

I guess if there are no regulations then my fight with the builder will need to move onto the guttering not being suitably specified.

put in snow boards above the gutter problem solved

Thanks. That's the plan. It seems to be the only solution.

My argument is in a two year old house that the builder holds some responsibility. So if I can find a regulation or guideline somewhere I can quote I have chance to hold them to account.

Failing that I will just pick up the bill.

Mind you though. Finding installers for snow boards or snow guards in the south east of Engalnd is a bit tricky. Not that many need them this far south.

Cheers

You can get snow guards from most good builders merchants and a roofer/builder would be able to fit them.
