504 Malcolm Ave, Sikeston, MO 63801
Prepared for Sample report — contractor review
For contractor review. Confirm the building, complete roof coverage and measurements on site before a final quote or material order. The plan may omit sections hidden or unresolved in the source data.
- Eave
- Rake
- Ridge
- Hip
- Letters name the roof planes in the table; every edge's length is on the next page.
How it was measured. Measured plane by plane from the USGS 2024 aerial laser scan, 16 points per square meter. Area measured, edges measured, pitch measured. The scan was measured twice from separate halves of its laser returns to check the result.

|---|---|
| Eaves | 211 ft |
| Rakes | 7 ft |
| Ridges | 40 ft |
| Hips | 95 ft |
| Drip edge (eaves + rakes) | 218 ft |
| Ridge cap (ridges + hips) | 135 ft |
Roof planes
| Plane | Faces | Pitch | Area | Share | Pitch band |
|---|---|---|---|---|---|
| A | W | 4/12 19° | 1,012 sq ft | 39.4% | Lower pitch |
| B | E | 4/12 19° | 987 sq ft | 38.4% | Lower pitch |
| C | N | 4.1/12 19° | 285 sq ft | 11.1% | Lower pitch |
| D | S | 4/12 18° | 284 sq ft | 11.1% | Lower pitch |
Pitch by area
Moderate roof: 4 planes, 0 ft of valleys, 0% of the roof steeper than 6/12.
Material planning worksheet
Planning quantity for 25.7 squares of roof at 13% waste: 29.3 squares (rounded to full shingle bundles).

| Underlayment rolls | 3 |
| Ice & water rolls | 4 |
| Drip edge (10′ pieces) | 22 |
| Starter bundles | 3 |
| Hip & ridge cap bundles | 5 |
| Ridge vent (4′ pieces) | 10 |
| Coil nail boxes | 2 |
| Pipe boots | 3 |
| Box vents | 4 |
| Decking sheets (4×8) | 5 |
| Waste | 0% | 5% | 10% | 12% | 15% | 20% |
|---|---|---|---|---|---|---|
| Squares | 25.7 | 27.0 | 28.2 | 28.8 | 29.5 | 30.8 |
| Sq ft | 2,567 | 2,696 | 2,824 | 2,875 | 2,952 | 3,081 |
Measurement verification
What the available data supports, and what still needs an on-site check. A remote measurement does not establish the roof's condition.
| Item | Basis and checks |
|---|---|
| Roof area | Measured remotely |
| Edge lengths | Measured remotely |
| Pitch | Measured remotely |
| Stories | Check on site · Estimated — confirm on site |
| Laser scan | 2024 · MO_SE11County_1_B24 |
| Repeat measurement | 0.2% difference between scan halves; repeatability is not proof of accuracy |
Scope and allowances
Quantities used in this estimate. These are planning assumptions and allowances, not findings from a site inspection.
| Included in the calculation | Quantity / allowance |
|---|---|
| Material waste allowance | 13% |
| Tear-off | 25.67 sq |
| Disposal | 25.67 sq |
| Pipe flashing | 3 |
| Box vents | 4 |
| Chimneys | 0 |
| Skylights | 0 |
| Decking replacement allowance (4×8 sheets) | 5 |
Confirm the final scope, concealed damage, permit requirements and any additional work with the contractor. This worksheet does not add an item to a signed roofing agreement.
Site inspection checklist
Complete with the property owner or crew before final pricing and material ordering.
- Confirm the selected building, every attached roof section and any excluded detached structures.
- Inspect flashing, roof penetrations, skylights and leak areas; record the work required.
- Confirm existing roof layers, decking condition and any replacement beyond the allowance.
- Check ventilation, drainage and applicable local requirements for this property.
- Confirm site access, property protection, debris removal and material delivery.
- Check final quantities and product specifications before placing an order.
Measurement notes
- No satellite roof data here. Every roof plane was measured from a 2024 USGS aerial laser scan (16 points per m²); confirm small sections on site.
- Demonstration of a real property from public aerial data, not a customer job. Measurements have not been checked on site. Small or obscured sections may be missed.
Measured from above. Confirm the measurements and the roof's condition on site before ordering materials.
