Pent shed roof pitch

[Lawrence Zarb]

I am going to build a 16 x 10ft pent roof shed and would like to know what pitch I should use for the roof?

[Andrew Mawson]

once you've satisifed the materials minimum pitch angle it's down to aesthetics.

Tiles need 41 degrees, slates a bit less at 35 degrees, and sheeting very much less.

Torch on felt will go down to 10 degs to flat , some roof tiles go down to

12.5 degs and fastnet fibre cement slates go down to 22.5 degs. Or you can go up to 45 degs on all roofing materials or steeper.

Sorry for not making it clear, but it will be a felt roof..

well it will leak whatever pitch its at, so don't worry ;-)

[Lawrence Zarb]

A useful answer!!

[Bob Mannix]

More useful:

"It will leak eventually whatever pitch you use"

But felt is cheap and quick. There's nothing wrong with felting as long as you factor in complete replacement (10 years for professional three layer torch-on felt, 2-3 years for single layer nailed on a shed) as a permanent feature. As others have said, with felt the pitch is (more or less) irrelevant so just make it as convenient. Too steep and getting the felt actually on may be a problem, really flat you'll get pooling, which you don't want.

[The Natural Philosopher]

Agreed.
