forest paul is right that a pitched roof is much more waterproof and long lasting, even with modern materials
plus if it is constructed with a a south elevation it is far more efficient for solar panels than a flat one

Err - how about a FLAT roof, ie in a single plane, pitched at an angle of say 15*? Excess water runs off but the roof still gains maximal sunlight. A "flat" roof need not be a "horizontal" roof.
We get trapped by language sometimes.

STYRBJORN. | what you are describing is a monopitch roof - flat roofs are horizontal because if they aren then they arent flat to (ie parallel with) the ground. QED

I would think that 'horizontal' is better described as 'a line or plane at right angles to the local direction of the force of gravity'!

STYRBJORN. | By that logic, every roof other than domes and the like are flat 
In this instance, Animartco was patently referring to a "flat" flat roof, i.e. one which is parallel with the floor below it.
For the record, I'm with Eeyore on this. I've been around the building industry all of my working life, and lost count of the number of times I've seen water penetration problems with flat roofs.
Eeyore is correct again with regards to solar energy capture - i.e. the best typical roof structure would be one pitched at right angles to the sun's line of travel across the sky, thus enabling it to "face" the largest possible amount of direct solar radiation.
The best structure overall, would be one that followed the sun's line of travel, (i.e. maintaining itself full face on to the sun), but that is obviously not practical for anything other than purpose built solar power stations.

Mike. |

Well Nyaah to the pair of yez. Would you care to discuss whether the universe follows Euclidean plane geometry, Lobachevskian closed space or Gaussian open curvature?
Replies on a postcard please. A flat space Euclidean one for preference. WITH A STAMP!!! |

OK "the universe in which we happen to exist" If you accept the Everett-Wheeler-Deutsch model of quantum mechanics, as I do, then there are an infinite number of alternative universes but we can never contact any of them. We are still stuck with the one in which we just happen to be.
Anyway what da wot not. It's oh flux in the morning and I am listening to Maddy Prior and Steeleye Span. Bet I'm happier than you!

Regards,
Mike. EDIT - Just realised I've fallen all too easily into the trap of continuing the off topic debate. (On my own thread too  ). Better leave things at that in case anyone wishes to return to the original subject of the thread.
