Planning to build a woodshed, model 24 sqm. I would really like to have tiles on the roof, but the pitch angle will only be eight degrees, and someone claims that it's way too small an angle for roof tiles. How dumb on a scale of 1 to 10 (10 being idiotic) is it to do it anyway? Located in southern Sweden, zone 2/3.
10 votes I.
You have too little of an inclination, it should be at least 14 degrees I believe.
This is to ensure good drainage of snow and rainwater.
Also, I believe the wind has an easier time catching the "tiles" at shallower angles.

I might as well be kinder and lower a couple of steps, but as mentioned, the slope is too low for tiles, so it can't be right. A suitable slope is between 10 and 27 degrees depending on the tile model and underlay, but generally, I wouldn't go below 14 either, and I would preferably want 22 for tiles.
Is there an increased risk of the wind taking the tiles then?
Besides any potential problems with wind, I think the level of foolishness is determined by the building's design and its use.
Residential house - completely foolish
Uninsulated shed with good opportunities to dry out - not as foolish.
edit:
LaFarge roofing says 14° for concrete tiles and some of the clay tiles in their range, 22° applies for Vittinge and Dantegel clay tiles.

The storage area should not be insulated. It will be very airy. Furthermore, completely open in both directions, year-round. I don't believe in the wind problem, but maybe water can blow in under the tiles a bit more easily? Right now I am set on 14 degrees, which could work.
If it's only going to be wood in the shed, you can actually nail only battens (thicker than usual, perhaps 45*70 or 45*95) onto the rafters, and lay the tiles so you can see the underside of the tiles from inside the shed. Screw each tile in place so you don't have to worry much about the wind. I think it's nice and tidy, and also very well-ventilated ;-)
I have a shed with a 9-degree roof slope. On that, I have laid vittingtegel (two-paned) that I had lying around. I built it two years ago, and it's also a wood shed. Works great with that slope. Ok, maybe a little more snow gathers, but so what, add some larger beams etc. if you're worried (I'm not). Mine is sheltered, so I can't say if the wind would take them, but I can't believe it would.
Incidentally, I have 12 degrees or maybe it was 11 on my dormers, and they've "only" been on the house for 103 years without any issues, so it definitely works.
The only problem I have with the shed is that it stands under a tree and therefore a lot of debris falls on the roof, and the water flow is too weak to carry the leaves away, so I'll probably have to brush it off at some point in the autumn (haven't bothered so far).
I vote 1 on the stupidity scale

Can't the slope be increased a little then?
On the other hand, I don't think it matters at all. On a residential house, you should probably try to avoid it, but on a wood shed, it doesn't matter. Nail down the tiles if you're worried about them being blown away. I think the risk is minimal, especially with concrete tiles. Firstly, they are very heavy, and secondly, the fit is so good that they stay in place just for that reason. I'd probably give it a 1 on the idiot scale too.

Suitability for the individual. (or building in this case )
Use brick, ensure there are decent opportunities for moisture to dry if the underroof happens to get a little wet sometime when it storms and rains.
Secure a few more tiles if you're worried about tiles blowing away.
I take zero responsibility for the advice but I'd probably dare myself anyway.

According to the plan, our garage should have a slope of 10 degrees (monopitched roof), and I've been considering using concrete tiles there (same as the house).
What is it that actually makes it unwise to have less than a 14-degree slope?
Of course, I've planned to have proper underlayment below the tiles, possibly more robust materials than YAP 2200, and I'm considering nailing all the tiles.
