The skill of the thatcher.
Many roofs have areas near or below this minimum pitch.
Thatching is the craft of building a roof with dry vegetation such as straw water reed sedge cladium mariscus rushes heather or palm branches layering the vegetation so as to shed water away from the inner roof since the bulk of the vegetation stays dry and is densely packed trapping air thatching also functions.
Roof shape and design.
The quality of the material used.
The pitch of the roof might be even higher than 45 but the inclination of the individual reed stalks is just 12 whereas 30 are recommended.
This is normally acceptable.
A steeply pitched roof is of the utmost importance.
Thatched roof reed the material durability criteria for the durability of thatched roofs.
Thatch is used occasionally on new dwellings and demands a roof pitch of at least 45 and more likely 50 to allow the rain to flow off quickly and prevent ingress.
A thatch roof should have a minimum pitch of 45.
The pitch of the roof.
The pitch of a roof is its vertical rise over its horizontal span.
This steep pitch is also an essential ingredient of cottage style.
The proximity of trees.
The typical slope of a thatched roof structure is 50 degrees.
The steep slope is needed so that water will run off from the roof surface with minimum penetration into the thatch.
