Satellite roof facets
Locate the property, trace each visible roof plane and apply the pitch that belongs to that facet. Footprint area is converted into true sloped area.
Roof measurement workspace
Measure the roof before you climb it.
Trace roof planes from above, enter verified field dimensions, import LiDAR geometry and build a structured Ottawa roofing takeoff in one browser-based tool.

Three ways in
Use the measurement source you actually have.
RoofOttawa is not locked to one perfect data source. Start remotely, confirm in the field, or import measured geometry—and keep the source grade visible.
Manual field dimensions
Use tape, laser or blueprint dimensions when accuracy is already in your hands. Length, run and pitch stay visible instead of disappearing into a black-box estimate.
Enter dimensionsLiDAR import
Bring in pre-measured facets as structured JSON. Imported planes retain their measurement source and enter the takeoff without applying a second pitch correction.
Import geometryCross-reference engine
Top view gives the footprint. Elevation gives the pitch.
The useful measurement is where separate views agree. RoofOttawa keeps those inputs visible so a remote trace can be checked against a gable view, field dimension or LiDAR scan.

Ottawa-specific logic
The material sheet should understand the climate.
The calculator separates geometry from local planning assumptions. Ottawa’s winter exposure matters, but every climate convention remains clearly labelled for field and municipal confirmation.
Freeze–thaw planning, without pretending it is a permit.
Ice-and-water protection, waste allowance, eaves, valleys and complex roof geometry all affect the material list. RoofOttawa brings those planning inputs forward while keeping the final verification boundary obvious.
EavesMembrane quantity based on measured eave length
WasteSimple, typical or cut-up roof allowances
RidgeSeparate linear quantity for ridge-cap planning
GradeL0–L4 source confidence remains visible

Start with the roof you have
One address. Multiple measurements. One defensible takeoff.
Build the first pass remotely, then improve the grade as field dimensions, pitch confirmation or LiDAR geometry become available.
