Gutter profiles
Half-round, square, ogee and higher-capacity forms may be available. Appearance is only one selection factor.
Rainwater · Connected system ordering
Gutters. Outlets. Downpipes.
One connected route.
Choose the rainwater system around roof catchment, profile, falls, outlets, downpipes and final discharge. Compatible components matter more than mixing parts that merely look similar.
Choose the system, then schedule every fitting
Exact profiles, dimensions, colours and technical limits depend on the selected range. Confirm them before assuming a replacement component will connect to an older system.
Outlets and angles
Running or stop-end outlets, internal and external angles, unions and stop ends must match the chosen range.
Downpipe system
Pipe, sockets, bends, branches, clips and shoes are scheduled around the outlet and discharge route.
Brackets and fixings
Support centres, fascia condition, falls, building height and fixing substrate are installer checks.
Information needed before ordering
- Roof plan or dimensions, pitch and valleys feeding each run
- Straight lengths, internal and external corners, and stop-end positions
- Number and location of outlets, downpipe route and final discharge
- Existing system manufacturer or a clean sample with accurate dimensions
- Colour, building height, access, full postcode and unloading constraints
Rainwater problems and decisions
Leaking gutters and joints
Trace failed seals, movement, poor falls and support before replacing isolated fittings.
Choosing a gutter profile
Compare catchment, outlet layout, capacity information, appearance and compatibility.
System compatibility
Identify the manufacturer and dimensions before mixing old and new components.

Local routes help customers prepare an accurate order while making no claim of a Forti Nova branch outside Blackburn.
Rainwater system questions
Which gutter profile should I choose?
Profile selection depends on roof catchment, pitch, valleys, run length, outlet position, appearance and the selected system’s capacity information. Larger or unusual roofs may need a drainage calculation by the responsible designer.
Can a new gutter join an old system?
Only when dimensions, seals and fittings are confirmed compatible. Similar profile names or appearance do not prove that components from separate systems will connect reliably.
Why does a gutter overflow even when it is not broken?
Possible causes include debris, poor falls, inadequate support, too few or blocked outlets, concentrated flow from valleys, or a downstream restriction. The whole route should be inspected before parts are selected.
Does Forti Nova install gutters and downpipes?
This page describes product supply. Survey, hydraulic design where required, lawful discharge, access and installation remain the responsibility of the customer’s contractor or designer.
