Roof Leak Repair in Kansas City

Nearly every homeowner who calls us about a leak points at the ceiling and asks what is wrong with the roof right above it. Fair question. It is also, most of the time, the wrong place to look.

Water that gets through the roof surface lands on the underside of the decking or on top of a rafter. It does not fall straight down. It runs along the wood until it hits something that stops it, and then it soaks into insulation, follows a wire, or finds the drywall seam. We have traced leaks that entered eleven feet uphill of the stain. On a low-pitch roof over a finished bonus room, that distance can be greater still.

That is why we do not price leak work by guessing. We go into the attic where there is access, we look for the staining pattern on the sheathing, and we follow it up. On the roof side we lift courses where we have to. A leak repair that skips the tracing step is just a sealant patch on the closest thing that looked bad, and those come back.

Pipe boots are first, and it is not close. The rubber collar around a plumbing vent stack dries out and splits, usually on the sun side, and once it opens the stack becomes a funnel straight into the attic. Most of the split boots we replace are between eight and fifteen years old on a roof that still has plenty of shingle life left.

Step flashing at a sidewall is second. Where a roof plane runs into a wall, individual pieces of metal are supposed to be woven in with each shingle course. When siding gets replaced by someone in a hurry, that flashing often gets face-nailed or caulked instead of woven, and the wall dumps water behind the roof rather than onto it.

Then chimneys. Counterflashing has to sit in a cut mortar joint. On older brick around here the joints go soft, the metal loosens, and water walks in behind it. Valleys wear through where two planes concentrate runoff, especially on steep-to-shallow transitions. And exposed nail heads back out over years of thermal movement, lift the shingle slightly, and let water under the course.

Ice dams are their own category and they are seasonal. If your only leaking happens in January along the eave, the roof surface may be fine and the problem is heat escaping into the attic.

Someone answers the phone. That is not a small thing at eleven at night in the middle of a storm, and it is the reason a lot of people call us in the first place.

On site we start inside if you have an active drip, because the interior tells us the elevation and the direction the water is running. Then we get on the roof. We photograph every suspect condition, we mark it, and we show you the pictures on the tailgate before we quote anything. If the fix is a forty-dollar boot and an hour of labor, we tell you that.

If weather is still coming and the opening is significant, we can dry it in temporarily so the inside stops taking damage, then come back and do the permanent repair in workable conditions. Tarping is a holding action, not a repair, and we say so plainly rather than leaving one up for a month and calling it done.

Sometimes it is. A repair makes sense when the roof around the failure is sound: the mat is intact, the granule cover is even, the shingles still seal down, and the leak is one identifiable defect.

A repair stops making sense when the field is brittle enough that walking it creates new damage, when there are leaks at three unrelated locations, when the decking has gone soft across a wide area, or when the shingle line has been discontinued and nothing available will lie flat next to it. Patching a roof in that condition buys a season and costs you the money twice.

We will tell you when your roof is fine, too. That happens more often than people expect. A stain that has been there since before you bought the house, with dry decking above it and no active path, is a painting problem, not a roofing one.
