Roof leak repair is its own service because the work is diagnostic. General roof repair may already know the broken tiles or the missing tabs. A leak often does not announce the entry. Water runs along underlayment, follows a rafter, and appears in a room several feet away. Commercial roof leak repair adds another path: sideways through insulation under a membrane until it finds a seam in the deck.
If water is coming through during the storm and the ceiling is actively dripping, stabilize first. That visit is emergency roof repair. The permanent close-up still happens here or on the system page that matches the roof. Flat roofs and TPO have their own leak patterns, described on flat roofing and TPO roofing.
Where roof leaks actually start
On houses, the common entries are split pipe boots, open step flashing, counterflashing that has pulled out of a chimney, valley metal that has rusted through, and skylight curbs. Dead valleys and roof-to-wall joints fail more often than the middle of a shingle. On metal roofs, the leak is often a fastener washer, an end lap, or a penetration boot, not a random hole in the panel.
On low-slope roofs, look at seams, patches over patches, pitch pockets, and the area around drains. Ponding does not always mean a puncture. It means water sits long enough to find the weakest joint. Coating over that joint without finding the wet insulation is how leaks get quieter for a month and then return.
How the source is traced
We start with your timeline: which rain, which wind direction, which room. Then the attic, if it can be entered safely, to see whether the deck is wet, stained, or open to daylight. On the roof we test the details that match that stain, not every square of covering. When the source is still ambiguous, a controlled water test isolates one detail at a time.
Roof flashing repair is often the result of that test. The metal is replaced or re-secured, and the covering around it is woven back so the flashing is not a dam. Sealant is a gasket in specific joints. It is not the repair by itself when the metal has a hole in it.
What the repair includes
You get the finding, photos of the entry when we can reach it, and a scope that names the pieces to replace. The opened area is dried in the same day. Interior drywall, paint, and any mold concern are not roofing. We will tell you if the ceiling needs another trade. Pretending to be that trade would only blur who is responsible for the dry-in.
If the tracing shows the field of the roof is used up, we stop selling a leak repair and price replacement. A leak on a brittle roof is a symptom of the system, not a single joint. You should hear that before more sealant goes down.
Cost and property differences
Roof leak repair cost depends on how hard the source is to prove and what has to be opened. A visible boot on a one-story roof is straightforward. A leak that only appears in wind-driven rain, three stories up, at a chimney, is not. Commercial leak repair adds safety planning around equipment and tenants. House leak repair adds occupied rooms and attic access. Both are available in Denver, Colorado and surrounding areas.
After the repair, the same detail should be watched through the next serious rain. If a second stain appears in a new place, that is new information, not automatic proof the first repair failed. Maintenance keeps debris out of the valley we just rebuilt. The routine is on the maintenance page, and a documented look is a roof inspection.
What the ceiling does after the entry is closed
Closing the roof does not dry the ceiling the same afternoon. Wet drywall and insulation can keep dripping stored water after the entry is honest. We will tell you if that is likely, and we will not repaint the room as part of the roof scope. If the stain grows on a dry day, the deck may still be shedding water it already absorbed. If it grows only in the next rain, the entry is not closed and we need to be back on that detail, not on a new theory in another room.
Keep the photos you took before we arrived. They show the original room, which matters if a second stain appears and someone argues it was always there. Note the wind direction on the next storm. A leak that returns only from the north is still a specific detail, often a wall or a ridge, and it is faster to test than a full re-inspection of every slope. That follow-up is included in the way we talk about the repair. It is not a new project invented to extend the invoice, and it is not a reason to jump straight to replacement unless the field itself is finished.
Leak repair questions
Why does the stain not line up with a hole?
Water follows the deck and the framing. The entry can be upslope of the drip. Tracing is the work, not a bigger patch at the stain.
Can you find a leak that only happens in certain wind?
Often, yes. Wind-driven rain points at walls, ridges, and rakes. We use the direction you observed and test those details rather than soaking the whole roof.
Is a leaking skylight always a bad skylight?
No. Many wet ceilings under intact glass are flashing or curb problems. The skylight page separates those cases.
Will sealant stop a commercial roof leak?
Only at a compatible joint that is clean and dry. A wet insulation layer or an open seam needs the membrane repair described under commercial roofing.
What if you cannot reproduce the leak that day?
We document what we ruled out and what still needs a wet test or the next rain. Guessing a location to close the visit is how stains come back.
How do I start?
On the contact form, note the room, the last storm, and the roof type. If it is dripping now, say that it is urgent.
