Water does not leak straight down. Finding where it got in is most of the work, and it is the part a patch over the stain skips entirely.
How a repair works
A ceiling stain marks the place water finally gave up, not the place it got in. Water lands on the deck, runs down the underside of the sheathing, tracks along a rafter until something interrupts it, and comes through the drywall somewhere else entirely. On a low-slope roof it can travel a long way. Repairing the spot under the stain is the most common way a roof gets “fixed” twice.
So a repair starts with a diagnosis, and the diagnosis usually needs both sides: the roof, where the entry point is, and the attic, where the path is. Daylight through the deck, a clean run of staining down one rafter, a wet patch of insulation that does not line up with the ceiling — those tell you more in five minutes than an hour of walking the field.
Flashing. Where the roof meets something that is not roof: a chimney, a wall, a dormer, a valley. This is where most roofs leak, and it is almost never the shingles’ fault.
Pipe boots and vent collars. The rubber collar around a plumbing vent perishes and splits in well under the life of the shingles around it. It is one of the cheapest components on a roof and one of the most frequent causes of an interior leak.
Wind-damaged shingles. Creased tabs, lifted courses, and shingles that have lost their seal strip. A creased shingle often looks intact from the ground and is already broken through the mat.
Valleys. Where two planes dump their water into one channel. Volume plus debris plus a tired membrane is a predictable leak.
Ridge and hip. Cap shingles and ridge vent, which take the wind first and often fail before the field.
Localised decking. If the sheathing under a long-running leak has gone soft, we cut it out. Fastening a repair into rotten plywood is not a repair.
A repair is the right answer when the roof around the problem still has service life in it: the field holds its granules, the mat is not exposed, and the failure is local. A pipe boot on a nine-year-old roof is a repair, full stop.
It is the wrong answer when the roof is worn out everywhere and the leak is simply the first place it showed. At that point every repair buys a few months and the next one arrives from a different direction. We will tell you honestly which situation you are in, and if the honest answer is “this will need replacing within a year or two, here is what a repair actually buys you,” you will get that answer too — along with the option to just do the repair.
Where leaks start
In rough order of how often they turn out to be the cause, not in order of how dramatic they look.
How it runs
01
On the roof and, where we can get to it, in the attic. We are looking for the entry point, not the stain.
02
Photographs of what we found and a plain explanation of why the water ended up where it did.
03
The failed part is replaced, not sealed over. If the deck under it has gone soft, that comes out too.
04
If the roof around the repair is near the end, you will hear that now rather than at the next leak.
Straight answers
Nothing here is hidden behind a dropdown. If a question you have isn't answered, call and ask.
One section, when the rest of the roof still has life in it. That is the majority of repair calls. Where we will push back is on a roof that is failing everywhere: repairing one corner of it is not a fix, it is a deposit on the next leak, and you deserve to be told that before you spend the money rather than after.
Close, rarely perfect. Asphalt shingles weather, granule colour shifts over years of sun, and manufacturers change their blends. A repair on a ten-year-old roof will be visible if you go looking for it from the right angle. On a visible slope we will tell you what to expect before we start.
Yes, where the roof can be safely accessed. A tarp is a stopgap that keeps water out of your house until the weather clears enough to do the actual repair — it is not the repair, and we will not bill it as one.
Sometimes. It depends entirely on why it is leaking. A split pipe boot on a twenty-year-old roof that is otherwise holding its granules is worth repairing. A leak coming through an exposed mat in the middle of the field on the same roof is not — that is the roof telling you it is done. The inspection is what tells the two apart, and it costs you nothing.
Often not. A dried stain does not disappear on its own; drywall and paint hold the mark. The test is whether the stain grows or darkens after the next real rain. If it does, call us back — on a leak we diagnosed, that is our problem to finish, not a new job.
If the cause is a covered event such as wind or hail, yes, and how the damage is documented matters as much as the damage itself. See insurance restoration. Ordinary wear and age are not covered events, and we will not tell you otherwise to help a claim along.
