Roof trim
Rainwater system
Sized for snow-melt, not just rainfall.
Steel half-round gutter with brackets, outlets, stop ends and angles, colour-matched to the roof.
Profile cross-section — schematic, not to scale
Overview
In a Nordic climate a gutter's hardest day is not the heaviest rain — it is the first warm afternoon in March, when the whole roof melts at once and a sheet of snow arrives in the gutter with it. Sizing and bracket spacing follow from that, not from rainfall tables alone.
Supplied as a complete system: gutter, brackets, outlets, stop ends, internal and external angles, unions and expansion joints, in the same coating as the roof.
Bracket centres set for sliding snow, not just water weight.
Every fitting in the run supplied from one source.
Produced from the same coating range as the roof.
