[ongley]

Hi i have been told i have a low pitch roof and have the wrong tiles on it for that pitch, could you tell me what sort of tiles in need.
Thanks

35 degrees is too low for hand made clay Plain tiles

30 degrees is too low for machine made Plain tiles

20 degrees is too low for natural slates

17.5 degrees is too low for man made slates

15 degrees is too low for most concrete tiles

It's all comparative. What's your pitch and what type of tile have you got?

marley wessex can go lo pitch, wouldn't win any beauty contests though! about 17.5deg with normal underslaters felt.

just mesured my roof seems to be about 10 degrees does this mean it is to low for tiles, if so what sort of roof does it need

looks like copper or lead then! seriously, tiling a 10 deg roof is not an option, its almost flat.

no my roof was like it when we bought it
Why do you want some tiles looks like I might have to replace mine

 

[noseall]

what sort of tiles?

sorry only joking they look well used and i probably wont get round to doing anything till summer any way

I think the only way for that low pitch is to use metal sheeting tile effect. Available up to 6m in length and 1m wide.

Best thing to do is ask Building Control, i've just submitted an application (up here in the windy north) for a 14 degree lean to roof with artificial slate.

Now the min. required for slate is 17.5 degrees. But my local BCO has said that if we put on a plywood decking & 2 layers of bonded roof felt, with the battens & tiles over - we're ok.

The thing u gotta remember is that in windy + / or heavy rain areas you might constantly get problems, esp. with a 10 degree roof.

Maybe speak to your BCO + offer what i've said above + increase your headlap of the tiles from the min. 75mm to say 100mm???

I know this is an old topic, but one of the problems with searching for info is the plethora of possibly relevant results, so tagging onto an existing one which is completely relevant may help people searching in the future.

My council's Building Control advice for residential stuff says, when talking about single-storey rear extensions like wot I want:

Generally roof designs must not obstruct
any adjoining properties (house and
garden) right to sunlight and daylight. To
help prevent this it is recommended that
the roof pitch is set to an angle as
shallow as possible (depending on the
roof type, construction and material).

Now I don't mind using some special system, nor do I mind if it costs a bit more, nor do I mind if the tiles are only decorative, but I really, really want a roof with a 10-11° pitch (rising 0.7m in 3.7m).

Does anybody have any pointers to systems/design details such as Onduline?

Are there any effective water-repelling treatments that can be applied to tiles to reduce the risk of them getting too wet?

i can't think of anything that will last.

i guess this is why there is a minimum pitch for fragmented roof coverings. single skin roofs will deal with any pitch.

unfortunately those that are fragmented and shallow pitched need to resist fluctuations in temperature, persistent rain, the odd covering of snow AND still remain watertight.

don't be surprised if some company has a miracle cure.

You can go a lot lower with roof tiles if you use the onduline undertile system
