Roofing prices in Johnson County rose sharply between 2020 and 2024 and have been comparatively flat since. These are the ranges we are actually quoting in Olathe in 2026 on a typical 2,000 to 2,600 square-foot house.
| Roof type | Typical Olathe home | Per square (100 sq ft) installed |
|---|---|---|
| Architectural asphalt shingle | $11,500 – $19,500 | $420 – $620 |
| Class 4 impact-resistant shingle | $14,000 – $24,000 | $520 – $760 |
| Stone-coated steel | $24,000 – $38,000 | $900 – $1,300 |
| Standing-seam metal | $28,000 – $48,000 | $1,050 – $1,600 |
| Exposed-fastener metal panel (outbuilding) | — | $900 – $1,500 |
What moves your number
- Pitch. Anything over about 7:12 needs staging and slows everything down. A steep Cedar Creek two-story can cost 25 to 40 percent more than the same square footage on a Havencroft ranch.
- Layers coming off. Two layers is roughly double the tear-off labour and double the disposal.
- Decking. Priced per sheet. On a 1950s or '60s house with plank decking, an overlay of sheathing may be needed, which is a real line item.
- Complexity. Valleys, dormers, skylights, chimneys, crickets, porch returns. Flashing and cutting is where the hours go — two roofs of identical area can differ by thousands.
- Access. Where the dumpster can sit, and whether a landscaped garden has to be protected.
- Ventilation corrections, if the attic needs intake opened up while we are there.
Where a cheap quote is cutting
If one bid comes in thousands under the others, it is not because they found a cheaper supplier. Ask these four questions and the gap usually explains itself.
- Is it a tear-off or a recover? Going over the existing layer saves a day of labour and all of the disposal, and hides whatever the decking is doing. Under the 2018 IRC it is not even permitted where there are already two layers or the existing roof is deteriorated.
- Is the ice barrier in there, and how far does it run? Code requires it from the eave to 24 inches inside the exterior wall line. A token strip along the edge is cheaper and does nothing when water backs up.
- Is the flashing new? Re-using step flashing and pipe boots and sealing them with caulk is the single most common cut. It looks identical on day one and leaks in year three.
- How many nails per shingle, and is there a decking allowance? Four nails instead of six voids most wind warranties. And a bid with no per-sheet decking price is a bid that will grow on the day.
Financing and claims
If hail did this, most of the above is academic — on an approved claim you pay your deductible and the carrier pays the approved scope. See the Kansas claims guide. If you are paying out of pocket, we offer fixed-rate financing, and it is worth pricing the Class 4 upgrade at the same time because the premium credit offsets part of the difference every year.
Related questions
Why is my neighbour's roof so much cheaper?
Usually area, pitch and complexity rather than price per square. A simple gable ranch and a steep two-story with four valleys and two chimneys can differ by a factor of two on the same street. The other common reason is scope - a recover versus a tear-off, or a bid without a decking allowance that grows once the crew is on site.
Does a new roof add value when I sell?
It removes a deduction more than it adds a premium. Buyers and their lenders discount heavily for a roof at end of life, and a failed roof can hold up financing altogether. A documented new roof, ideally with a transferable manufacturer warranty and a Class 4 certificate, takes the argument off the table.
Is spring or autumn cheaper?
Late autumn and winter are quieter and scheduling is easier, but Kansas cold limits shingle sealing below about 40 degrees, so we plan around it. The genuinely expensive time to buy a roof is the fortnight after a county-wide hail event, when demand spikes and out-of-state crews arrive. Buying a roof on a calm Tuesday in November is a better experience than buying one in a queue.
