Roof Replacement in Kansas City

The words "roof replacement" cover a wide range of work, and the gap between the cheapest quote and the most expensive one in your stack is almost never about the shingle. It is about what is underneath and what gets replaced versus reused.

A complete tear-off takes the old roof down to bare decking. That matters because decking is the only place the real condition of a roof is visible. Water that has been getting in around a failed pipe boot for three years has been soaking the plywood the entire time, and no inspection from on top of the shingles will find it. Once the roof is open we can see it, and we replace what has gone soft.

From there the assembly goes back together in a specific order: ice-and-water membrane along the eaves and in the valleys, synthetic underlayment across the field, new drip edge at the eaves and rakes, new starter course, then the field shingle installed with the fastener count and placement the manufacturer specifies. Skipping or economizing on any one of those layers produces a roof that looks identical on day one and behaves very differently in year eight.

Shingles shed water. Flashing is what keeps water out where the roof meets something else, and it is where the overwhelming majority of leaks originate. Chimneys, sidewalls, dormers, skylights, plumbing vents, exhaust terminations.

Reusing existing flashing on a new roof is the single most common corner cut in this trade, and it is invisible to a homeowner. The new shingles look perfect. Underneath, twenty-five-year-old step flashing has been slid back into place and sealed. It will hold for a while. It is not a new roof.

We price new pipe boots, new step flashing, new counterflashing and new valley metal as standard on a replacement, and where something genuinely can be retained we say so and explain why. On houses with masonry chimneys we also look at the condition of the mortar, because counterflashing has to be cut into a sound joint and there is nothing to cut into if the joints are failing.

An attic needs to breathe, with intake low at the soffits and exhaust high at the ridge, and the two have to be balanced. When they are not, the attic runs extremely hot in a Kansas City July and holds moisture through the winter. Both of those shorten shingle life from underneath, where no warranty inspection is going to look.

The common failure we find across this metro is exhaust without intake: a ridge vent installed on a house whose soffit vents are painted over or packed solid with insulation. That configuration does not move air, and in some cases it pulls conditioned air out of the house instead.

We calculate the required net free vent area against your actual attic square footage and correct the balance as part of the replacement. It is not an upsell, it is the difference between a shingle reaching its rated life and falling several years short of it.

Before you sign with anyone, the estimate should tell you the shingle manufacturer, line and color; the underlayment type; where ice-and-water membrane is going; which flashings are being replaced versus reused; the ventilation plan; a stated per-sheet price for any decking that has to be replaced; who pulls the permit; and how debris and nails are handled at cleanup.

A one-line quote with a number on it is not a scope. It is also, in our experience, the leading cause of change orders, because everything that was not specified becomes an extra once the roof is open.

Two houses with the same square footage can have very different roof prices. The factors that matter most are the size of the roof measured in squares, the pitch (steeper roofs need more safety setup and work more slowly), how many layers are being torn off, how much decking turns out to be rotted, how many valleys, chimneys and skylights need flashing, and which shingle line you choose.

That is why we measure the roof and look at it before we give you a number. A written estimate should list each of those items, so you can compare bids on what is actually included rather than on the total alone.

Most residential replacements take a single day, with larger or steeper roofs running into a second. The crew protects landscaping and the driveway, tears the old roof down to the deck, replaces any soft decking, installs ice and water barrier at the eaves and valleys, lays underlayment, then new flashing, shingles, ventilation and ridge.

At the end of the day the yard is swept with magnets for nails and you get photos of the work, including the parts you will never see once the shingles are on. Our roof replacement timeline walks through each step.
