Limited data — grade D

We could not measure this roof well enough to print quantities. This report states what is known, what is missing and why.

Why the data is limited
- About 42% of the roof is hidden by tree canopy, over the 30% limit for a graded measurement (05 §6).
- 2 roof lines could not be classified from the geometry; a graded report allows none.
- The imagery source rates its own quality MEDIUM.
What would fix it
- Newer or leaf-off imagery for this address, re-measured and re-graded as a new version at no charge.
- An on-site measurement of the slopes under the canopy.
- A contractor edit that classifies the flagged lines; the edited version is graded on its own merits.
- Acknowledging this notice cannot unlock quantities or prices (VIEW-08).

Why this grade
Grade D: the roof is too hidden to measure from above and some lines could not be typed. Grade D withholds sizes, lengths, prices and orderable quantities.
Automated quality checks
| Automated check | Result | Detail |
|---|---|---|
| Canopy obstruction at most 30% | Failed | About 42% of the roof is under tree canopy in the imagery. |
| Every facet closes | Passed | All 4 facets are closed planar polygons. |
| Every line is classified | Flagged | 11.3% of line length is unclassified. |
| Shared lines counted once | Passed | Ridges, hips and valleys shared by two facets are single lines in every total. |
| Pitch within 0/12 to 24/12 | Passed | Every facet pitch is within the modelled range. |
| Totals recompute exactly | Passed | Withheld: it states a roof quantity (grade D). |
| Structures in scope | Note | Every structure on the property is included. |
| Source | Note | Synthetic sample geometry. A real report states its imagery source, date and quality here. |

What this report leaves out, and why
88 Example Grove Court, Allen, TX 75013
Not in this report
| Not included | Why |
|---|---|
| Roof area and squares | Withheld at grade D: an untrusted size would be ordered from. |
| Line lengths | Withheld: lines under the canopy are inferred, not seen. |
| Waste allowance | Not computed: it scales an area this report does not state. |
| Material estimate | Not produced: grade D never yields an orderable quantity. |
| Price or cost range | Not shown at grade D, and no acknowledgement unlocks one. |
What would fix it
- Newer or leaf-off imagery for this address, re-measured and re-graded as a new version at no charge.
- An on-site measurement of the slopes under the canopy.
- A contractor edit that classifies the flagged lines; the edited version is graded on its own merits.
- Acknowledging this notice cannot unlock quantities or prices (VIEW-08).
Check at the property
- Measure the slopes under the canopy on site; they are inferred here.
- Confirm how the roof sections meet where lines are flagged as unclassified.
- Confirm the pitch of each slope and the number of roofing layers.
- Note overhanging limbs that affect access, debris and future wear.
Limitations
- Every figure in this sample comes from an invented house built to exercise the report; it is not a surveyed property.
- Measurements come from above: wall heights, decking condition and the number of layers are not visible from the air.
- No accuracy or certification is claimed; a roofer confirms quantities on site before ordering.
