What a New Roof Costs in Kansas City

Roof area. Measured in squares, where one square is one hundred square feet of roof surface, not floor area. A roof's area is always larger than the house footprint because of pitch and overhangs.

Pitch. A roof steep enough that a crew cannot walk it requires fall protection, staging, and slower work. That is real labor cost, not a surcharge.

Complexity. Valleys, dormers, transitions, hips and penetrations all add cut waste, flashing work and labor. A cut-up thirty-square roof costs more than a simple thirty-square roof, sometimes considerably more.

Decking. Nobody knows how much is bad until the roof is open. An honest estimate states a per-sheet price so the exposure is known up front.

Flashing. Rebuilding flashing costs money. Reusing it costs nothing. This is the single biggest hidden difference between two bids.

Product. Three-tab, architectural, and impact-rated Class 4 are three different price tiers with three different service lives.

When homeowners show us three bids with a wide spread, the cheap one is almost never cheaper because that company is more efficient. It is cheaper because it is a smaller scope.

The things typically missing: new flashing, ice-and-water membrane, a decking allowance, ventilation correction, permit fees, and proper disposal. Any one of those can be a four-figure difference, and none of them are visible in a bottom-line number.

Ask each bidder the same five questions. What flashing is being replaced? Where does ice-and-water go? What is the per-sheet decking price? What is the ventilation plan? Who pulls the permit? The answers sort the bids faster than the prices do.

Impact-rated Class 4 shingle costs more up front and most carriers discount the premium for it. In a metro that takes hail as regularly as this one, that math often works out inside the life of the roof.

Six-inch gutter over five-inch is a small upcharge that meaningfully changes performance on a large roof. Correcting ventilation is inexpensive during a replacement and impossible to do cheaply later. Synthetic underlayment over felt is a modest cost for a real durability difference.

Where paying more is usually not worth it: extended warranty products that duplicate coverage you already have, and premium shingle lines whose advantage over standard architectural is mostly aesthetic.

On a covered storm claim the economics are different. The carrier pays their scope less your deductible, typically in two payments, and your out-of-pocket is largely the deductible plus any upgrades you elect.

Upgrades are where you have real choice. Going from standard architectural to impact-rated on a claim job usually costs you only the difference, which is often the cheapest opportunity you will ever have to put a better roof on the house.
