10 degree roof pitch
Discussion
Need some advice on the roof of a single story extension on my house. I'm converting a garage and making an extension which would change the house footprint from an L shape to more of a square. Problem is the garage has a flat roof which I want to remove and fit a pitched roof along the width of the garage and new extension. Problem is I'm restricted on roof height by the upstairs windows meaning I can only get 10 degrees roof pitch. I can only pitch the roof back towards the house.
The house has grey concrete tiles on the main roof, so would like something similar. If I can't find a suitable option I might just put a flat roof all the way across the front but I would rather have it pitched as I think it looks better.
Other houses have already put a pitched roof on there garages as the flat roof has failed but as I'm going for planning permission, building control need to pass it. So can I pick any of your brains to come up with a suitable way to do this? I hope what I've said makes some sort of sense!

I've had a similar thing on the two places I've done up, where the roof does not allow for a sensible pitch and yet I've not wanted a flat roof.
The answer for me both times was to build a roof with a tiles pitch all the way round to the height required, and then top off with a flat roof. The join between the top of the tiles and the flat roof is finished with ridge tiles.
Gives the look of a proper tiled pitch without the height needed to make the tiles meet at a ridge.

Have seen a few houses done like this lately and it doesn't look too bad.The answer for me both times was to build a roof with a tiles pitch all the way round to the height required, and then top off with a flat roof.

Another option would be a zinc roof which can go onto that roof profile no problem and would be a similar colour to your grey tiles.
I'm just having it done to my extension roof, see here http://www.pistonheads.com/gassing/topic.asp?h=0&a... although my pitch is 20 degrees.
Mine is natural grey although you can get several different colours.

I would be possible but as there are two windows, it all adds to the expense and I'm trying to do it all with a budget in mind.
I'm toying with the idea of just having a new flat roof put all the way across instead of trying go pitched. Was speaking to a roofer today and he said a flat roof done correctly should last many years before it needs re done. I was just looking to see if there were any easy options which wouldn't increase the costs. I'm only at the planning stage but wanted to be definate on it now. Thanks for the replies guys.

What is the height between the flat roof and the window sill? I'm toying with the idea of just having a new flat roof put all the way across instead of trying go pitched.

Here's a front view of my last house where there were two windows stopping me having a sloped roof on the garage. The side view below helps to show how it was built. The height between the falt roof level and the windows sills here was about 2 foot, maybe 3 max.
I have a 10 degree pitch roof on my extension (5m x 16m) and it's been nothing but a nightmare, so if you can avoid it I would.
We had the extension designed and kind of built, I'd bought a load of clay tiles only to be told at the last minute by the builder that having ran the roof trusses through some form of design software it wouldn't take the load at 10 degrees with the clay tiles. Our options then were increase the pitch by either going up above the bottom of the windows (like the picture in the thread above) or have a step down into the extension. Not liking either of those the builder came up with a lightweight tile http://www.metrotile.co.uk/ that allowed the original pitch.
Big mistake. We've had constant leaks which are being blamed on the low pitch despite it being 'okay' when it was built. Trying to get a roofer to work with the metrotiles is really difficult as they don't like them, they don't know them or just don't know how to fit or replace them. I've finally found someone that will touch them and we've had to strip them off, rebatten and refelt and refit the tiles three times now. Don't even think about fitting velux windows on a 10 degree pitch, we've had to remove two 1 metre ones as they leaked terribly. All due to the pitch.
Think carefully!

Hi,
We have the exact same problem as minghis. We bought our house 2 years ago and are now having serious problems with the roof because of the terrible storms we've had over the winter. Have been told lots of different things so much so we paid a surveyor to have look at it. He confirmed a 10 degree pitch :-( it was an extension built in 1989 and has passed all it's building regs despite having tiles on it designed for a minimum pitch of 22.5 degrees.
I was wondering minghis if you could let me know how you've got on with your roof please? Any advice you could give would be much appreciated.
Cheers
