A grade needs a defined basis
A simple A-through-F or good/fair/poor label is not enough. The grade should be tied to observable membrane and detail condition, repair burden, moisture concerns, drainage, age, warranty, and consequence of failure.
Use grades to compare, not to oversimplify
Two roofs can receive similar overall grades for different reasons. One may have localized flashing failures while another has broad membrane deterioration. Component-level notes keep the grade from hiding the real issue.
Connect condition to budget timing
Grades are most useful when paired with recommended actions and planning horizons such as immediate repair, monitor, restoration study, or replacement planning. That allows multiple Roof Sections to compete for capital on a common basis.
Practical owner checklist
- Define the grading criteria before scoring roofs.
- Keep component notes behind every overall grade.
- Tie grades to risk, consequence, and timing.
- Update the grade after significant work or new evidence.
Frequently asked questions
Does a poor grade automatically mean replacement?
No. A poor rating should trigger closer review of the causes, extent, repairability, moisture, and economics before a replacement decision is made.
How often should grades be updated?
Update them after meaningful inspections, major repairs, storms, restoration, or replacement so the current record reflects what actually changed.
