Roof Pitch Angle Recommendation

When it comes to the roof pitch for a thatched roof and its ridge, it is recommended that is it constructed at an angle between 45 and 60 degrees to make sure that water run-off is rapid so that roof life is prolonged.

Here is a picture of a Flax roof in County Donegal which unfortunately does not come anywhere near this. As one would guess it is the plastic lining below the thatch which is keeping this property dry!

In contrast here is a ridge we did in the Cotswolds which has a nice steep pitch.
