A Leak Almost Never Starts
Where It Shows Up
Repair work begins with finding where water is actually entering the roof — then an honest answer about whether a repair solves it or postpones a replacement.

A worn roof, brought back
Drag the seam across the photograph — or focus it and use your arrow keys — to move between the roof we walked onto and the roof we handed back.
A roof that had been patched from the top for years while the real entry points went unfound.
The leak traced to its source, the damaged area rebuilt, and the surface returned to one continuous, uniform field.
Six things that account for most of the repairs we do
Roofs are large, but they fail in a fairly small number of predictable places. Knowing which one you are dealing with is most of the diagnosis.
Active leaks
Water is inside the building. Whatever the roof looks like from the street, this is the urgent category, because every additional rain event adds to the damage in the ceiling, the insulation and the deck. Containing it indoors buys time; it does not stop the cause.
The first job is tracing the entry point, which is often some distance uphill from the stain.
Missing or damaged shingles
Wind breaks the seal between courses and lifts shingles; debris punctures them. Once the covering is gone in a spot, the underlayment beneath is directly exposed to sun and rain, and it is not designed to be the outer surface. It degrades quickly.
Shingles still in place but no longer bonded down are the ones people miss — they will come off in the next storm.
Cracked or displaced tiles
Broken pieces are usually the result of foot traffic — often from a previous trade working on something unrelated — or falling debris. Slipped tiles have lost their fixing.
On tile the important follow-up question is what condition the underlayment beneath is in, because that determines whether you are looking at a genuine repair or the first symptom of a larger job.
Flashing problems
Wherever the roof meets a wall, a chimney, a skylight or another roof plane, metal has to carry water out onto the covering. This is the single most common source of persistent leaks we are called to, and it is very often the leak that somebody has already tried to fix with sealant more than once.
Low-slope membrane concerns
On a flat porch, Florida room or addition: an open seam, a puncture, a lifted edge or a blocked drain. Because water sits rather than running off, a small failure has time to do far more damage than the same failure on a pitched roof.
The transition between a low-slope section and the pitched roof above it is a particularly common failure point.
Roof penetrations
Every pipe, vent, exhaust, conduit and equipment mount is a hole in the roof that has been closed again. Pipe boots crack from UV exposure and are one of the most frequent leak sources we find. Anything installed after the roof — satellite mounts, solar fixings, attic fans — deserves particular attention, because it was fitted by someone whose main job was not the roof.
How we decide whether to recommend a repair
The same four questions, in the same order, on every roof. If you want to challenge the recommendation, these are the things to challenge it on.
1. Is the cause identified, or only the symptom?
A repair that is not aimed at a confirmed entry point is a guess. If we cannot say where water is getting in, we will say that rather than sell you a repair and hope.
2. Is the failure local or systemic?
One detail failing on a sound roof is a repair. Failures appearing in unrelated places within a short period are a pattern, and patterns do not respond to patching.
3. How much service life is left overall?
The condition of the whole roof, not the damaged area, decides whether repair money is well spent. Repairing an area of a worn-out roof buys months at replacement prices.
4. What is the condition of what is underneath?
On tile, the underlayment. On low-slope, the insulation and deck. Once the layer below the covering has failed or is saturated, surface repairs seal the problem in rather than solve it.
Where we will tell you not to spend
If a roof is close enough to the end of its life that a repair only postpones the inevitable by a season, we will say so and let you decide. Some homeowners choose the repair anyway because the timing is wrong for a replacement — that is a legitimate decision, and it should be made with the facts rather than around them.
What actually happens when we come out
Free, and with no obligation attached to it. Usually an hour or two depending on the roof.
We look at the evidence you have
Where the stains are, when they appear, whether it happens in every rain or only wind-driven rain. That last question narrows the possibilities considerably before anyone goes up a ladder.
Useful to have ready
- Photographs of the stain when it was wet
- Roughly when it started
- Whether it is worse in particular wind directions
- Any previous repair work you know about
The attic or roof space
Looking at the underside of the deck tells you a great deal — staining, damp sheathing, daylight where there should not be any, and the direction water has been running. This is often where an entry point gets confirmed.
The covering, the details and the drainage
The condition of the field, and then every place the roof is interrupted: flashings at walls and chimneys, valleys, ridges, pipe boots, vents, mounts, terminations. Gutters and downspouts too, because blocked drainage causes leaks that look like roof failures.
Checked on every inspection
- Covering condition across the whole roof
- All wall and chimney flashings
- Valleys, ridges and hips
- Every penetration and anything mounted after the roof
- Gutters, outlets and downspouts
Photographs of everything that matters
You do not have to take our word for what is up there. Anything we recommend acting on is photographed, so you can see it yourself and get a second opinion on the same evidence if you want one.
Findings, and what we would do
What we found, what is causing the problem, what needs doing now, what can wait, and whether a repair genuinely solves it. If there is a scope, it is itemised so you can see what each part is for.
If water is coming in right now
Send a request and say clearly that the leak is active. Urgent situations are handled differently from planning enquiries, and knowing which one you are is the most useful thing you can tell us.
What to do while you wait
- Contain the water. A container under the drip, towels, whatever keeps it off the floor.
- Move what you can. Furniture, electronics and anything with value away from below the leak.
- Photograph everything. The ceiling, the water, the affected contents. Do it while it is wet — it matters for insurance and it fades.
- Stay clear of a bulging ceiling. A ceiling holding trapped water can come down suddenly. Keep people and pets out from underneath.
- Do not go on the roof. A wet roof is dangerous, and a person walking on it while investigating usually causes new damage.
We do not advertise 24/7 emergency service, and we do not publish a guaranteed response time. Both are claims that only mean something if they hold during the week after a storm, when every roofer in the county is booked — which is exactly when they usually stop meaning anything.
What we will do is tell you honestly when we can get to you when you contact us, and treat active water intrusion as more urgent than a planning enquiry.
If a ceiling is at risk of collapse, if there is standing water near electrical fittings, or if anyone is in danger, contact the appropriate emergency service rather than a roofer.
What repair means on each system
The diagnosis is similar. What can actually be done varies quite a lot.
| System | Typical repair | The limiting factor |
|---|---|---|
| Tile | Replacing cracked or slipped tiles; re-bedding ridge and hip pieces. | The underlayment beneath. If it has failed, surface repairs do not reach the problem. |
| Metal | Fasteners, seam closures, trim refixing, penetration flashings. | Whether the panel profile is still available if a panel needs replacing. |
| Shingle | Replacing damaged shingles; rebuilding flashing and valley detail. | Colour matching on a weathered roof, and how much life the general field has left. |
| Low-slope | Seam repairs, patching, flashing rebuilds, clearing drainage. | Whether moisture has reached the insulation. Once it has, patching seals it in. |
| Gutters | Refixing hangers, sealing joints, clearing outlets, correcting fall. | The condition of the fascia behind the gutter, and whether the run was ever sized correctly. |
What people ask when something is leaking
Because water travels. It enters at one point, runs along the underside of the deck, down a rafter or across a ceiling joist, and drops through wherever it finds a gap. Several feet of horizontal travel is normal, and on a low-slope roof it can be considerably more. This is why chasing the stain rather than the entry point produces repairs that do not work.
Usually, yes. Most leaks leave physical evidence — failed sealant, a cracked boot, a lifted flashing, staining on the deck, a compromised valley. A dry-day inspection finds the great majority of them. Where a leak is genuinely intermittent and nothing on the roof explains it, we will say that rather than guess, and we may want to see the roof under rain conditions.
Very common, and it usually means the sealant was applied where the water appeared rather than where it entered. Sealant is a finishing material, not a waterproofing system. When it is used to substitute for flashing it fails, and it also makes the original problem harder to see. We will show you where the previous work was done and what it was covering.
Sometimes it is exactly the right call. If the roof is generally sound and the failure is local, repair it. If the roof is at the end of its life and the failures are spreading, repairs become a running cost with no end. We will tell you which of those you are in and roughly how much time a repair buys, so it is your decision with real information behind it.
It depends on the current schedule and where the property is. When you send a request, tell us that water is coming in — active leaks are treated differently from planning enquiries. What we will not do is publish a guaranteed response time on this page, because a promise like that is only meaningful if it holds on the worst week of the year.
Contain rather than climb. Put a container under the drip, move furniture and anything valuable clear, and photograph the damage — including the ceiling and any wet contents — for your own records. If a ceiling is visibly bulging with trapped water, keep people away from underneath it. Do not go onto the roof.
Tell us what you are seeing
A stain, a drip, a missing tile, water behind the gutter — whatever it is, describe it in the form and we will come and find the cause. You get the photographs and the findings whether or not any work follows.
