Residential steep-slope takeoffs
- Roof area by facet with pitch factors, converted to squares.
- Starter, field shingles, hip and ridge cap, by product.
- Underlayment and ice barrier at eaves, valleys and penetrations as required by the local code and manufacturer.
- Drip edge, step and counter flashing, valley metal, pipe boots, vents and ridge vent.
- Tear-off by layer, dumpsters and steep or high charges where applicable.
Commercial low-slope takeoffs
- Membrane by system and thickness, mechanically attached, adhered or ballasted.
- Tapered insulation layouts, crickets and saddles, cover board.
- Perimeter edge metal, coping, counterflashing and expansion joints.
- Curbs, drains, scuppers, pipe penetrations and walkway pads.
- Wind-uplift attachment patterns at corners and perimeters, which are critical in Kansas wind exposure.
Kansas-specific roofing considerations
Hail
Kansas regularly ranks among the states with the most large-hail reports. Owners and insurers increasingly specify UL 2218 Class 4 impact-resistant shingles, heavier-gauge metal and hail-resistant membranes. We price the specified class and flag it when a spec calls for something different from the insurance scope. Read our Kansas hail roofing estimating guide.
Wind
High straight-line winds and tornado exposure mean wind uplift matters. Corner and perimeter zones on commercial roofs need enhanced fastening, and residential shingles may need high-wind nailing patterns depending on the manufacturer's warranty and local code.
Registration
Roofing contractors offering services in Kansas must register with the Kansas Attorney General under the Kansas Roofing Registration Act. Include registration costs in overhead if you are expanding into Kansas.
Waste factors we typically apply
| Roof type | Typical shingle waste |
|---|---|
| Simple gable | About 10% |
| Hip roof | About 12% to 15% |
| Cut-up roof with dormers and valleys | 15% or more |

Frequently asked questions
How do you measure a roof from plans?
We measure each roof facet in plan, apply the pitch factor for its slope, and total the true surface area in squares. Linear items such as ridge, hip, valley, eave and rake are measured separately, along with flashing and penetrations.
Do you price Class 4 impact-resistant shingles?
Yes. Class 4 shingles tested to UL 2218 are common in Kansas because of hail. We price the exact product line specified or provide an alternate for comparison.
Do you estimate commercial low-slope roofs?
Yes. We take off TPO, EPDM, PVC and modified bitumen systems including tapered insulation, cover board, edge metal, curbs, drains and walkway pads.
