True surface area
Sloped roof area is calculated from the geometry. It stays distinct from the horizontal footprint and ordering allowance.
Precision starts
with the whole picture.
Roof geometry is more than an area number. Understand the planes, slopes and edges that connect to the materials your project needs.

THE ROOF, IN CONTEXTA connected model.
This is a synthetic illustration, not a measured customer property.
A connected model.
A traceable result.
The planned independent engine combines roof-capable observations with geometric reasoning. Each facet and edge has an identity, a measurement status and a place in the report.

READ THE ROOF. UNDERSTAND THE QUANTITIES.
Every feature has a role.
Roof planes & pitch
Each supported plane has a stable ID and slope. Unknown pitch cannot quietly become a regional default.
Eaves & rakes
Roof-edge roles connect to starter and trim rules. Wall outlines and roof overhangs remain different evidence.
Ridges, hips & valleys
Shared edges are counted once. An absent valley and an unobserved valley have different meanings.
Openings & interfaces
Supported penetrations and roof-to-wall contacts carry their own evidence and uncertainty. Hidden conditions remain unknown.
Feature-level context
Strong area evidence does not conceal an uncertain valley or unsupported roof section. Completeness stays separate from a score.
THE ORDER SHOULD FOLLOW THE ROOF.Measure first.
Measure first.
Apply the rules second.
Starter strips, ridge caps, underlayment and other products use their own assembly rules. Adding waste never repairs missing roof geometry.
