Calculators / roof drainage

Roof geometry.
Gutters from the correct system.

Enter real gutter runs and downpipes, or use simple roof geometry only as a helper. System size, fixing spacing, outlet count, elbows and terminations are inputs; Numevaro does not design them.

Import transfers geometry only from the current project.

Quantity takeoff

Gutters and downpipes

A new project contains no default system size, fixing spacing or downpipes.

0. Units and parameter source

Display units System-parameter source

Changing display units does not change canonical quantities or price keys.

1. Geometry and run definition

Run definition Roof type Roof pitch °Building length mBuilding width mEave overhang mGable-end overhang m

2. Real gutter runs

Enter each separate run so stock lengths and connectors are rounded per real run.

3. Gutter system and stock lengths

Enter parameters from the selected source or link a catalog system. Text presets are hints only, not sizing.

System size / designation Gutter stock length mBracket spacing cmGutter waste %

The catalog links a snapshot of whole-system parameters.

4. Gutter fittings

In manual mode enter quantities from geometry, project documentation or the system. In automatic mode basic corners and end caps come only from the selected simple geometry.

External corners Internal corners Left end caps Right end caps Expansion / compensation

5. Real downpipes

Add only real downpipes. A new downpipe starts with zero height, zero elbows and no termination.

Numevaro performs geometry and purchase takeoff. It does not design drainage capacity, falls, diameters, outlet count/location, fixing spacing or expansion details.
