Roof leak? We'll diagnose it fast.

Guided, not a certain diagnosis. We confirm the cause on site · Leaking right now? Call us
Water coming in right now?
If it's actively leaking, the fastest path is a phone call. We'll give you a few safe steps to limit damage and an honest window for when we can be there.
Where GTA roof leaks usually start
Most leaks come from a short list of failure points. Knowing the likely cause helps you spot whether you need a small repair or a closer look.
Failed flashing
Metal around chimneys, walls, and skylights is the most common leak point. Old or reused flashing lets water in long before the shingles fail.
Cracked or worn valleys
Valleys carry the most water on your roof. When the valley liner cracks or the shingles wear, water finds the seam underneath.
Missing or wind-lifted shingles
A GTA windstorm can lift or tear shingles and expose the underlayment. Even one open spot can stain a ceiling after the next rain.
Plumbing & vent boots
The rubber collars around vent pipes dry out and split after about 10 years — a small, cheap part that causes a surprising number of leaks.
Ice dams
In winter, melt refreezes at the cold eave and backs water up under the shingles. The fix is often ventilation and ice-and-water coverage, not just a patch.
Attic condensation (not a leak)
Sometimes the water is warm indoor air condensing on a cold deck — a ventilation problem that looks like a leak. We check for this before recommending any repair.
What to expect
Three steps, in order: stop the water, find the real cause, then fix it with the scope written down first.
Stop the water (mitigation first)
If it is actively leaking, we focus on protecting your home first — a temporary cover or seal to stop the water. We tell you honestly what can and cannot be done safely in the rain or after dark.
Photo-backed diagnosis
We get on the roof and in the attic, find the real source, and photograph it. You see the same pictures we do — no vague "trust us, it is bad up there."
A written scope and a fix that lasts
You get a clear scope with the cause, the repair, and the price before any work starts. If a repair will not hold, we say so — and show you why.
Honest repair cost ranges
These are planning ranges for the GTA, not a quote. Your confirmed price comes after we see the roof and photograph the cause. Prices are before 13% HST.
Minor repairs
$300–$1,500
A split vent boot, a length of flashing, a few wind-lifted shingles, or a small sealing repair. In the GTA, repair visits commonly start around $495.
Major repairs
$2,000–$10,000+
Rebuilding a chimney saddle, re-doing a valley, or replacing a section with rotted decking. Deck replacement is the #1 hidden cost, billed around $3–$6 / sq ft once we can see it.
When repair stops paying off
If your shingles are near the end of their life or there are leaks in several places, repeated repairs cost more than a planned replacement.
Repair or replace? Decide here →We never quote a fixed number sight-unseen. Anything concealed — rotted decking, a second shingle layer — is named as a variable and priced only after we've seen it.
Roof repair questions, answered
How fast can you come out for a roof leak?
We respond as quickly as our real coverage hours allow and give you an honest time window — never a "same-day" promise we cannot keep. If it is after hours, we walk you through safe steps to limit damage until we arrive.
Can you tell me what is wrong from photos?
Photos help us prepare, but we do not present a remote guess as a certain diagnosis. The real cause is confirmed on site, in the attic and on the roof, with photos you keep.
Should I repair or replace my roof?
If the roof is generally sound and the leak is local — a vent boot, a length of flashing, a few shingles — a repair is usually the right call. If the shingles are near the end of their life or there are leaks in several spots, repairs stop paying off. Our repair-or-replace guide walks through how to decide.
Why do some roof leaks keep coming back?
Because the patch covered the symptom, not the source. Water often travels along the deck before it drips, so the stain is rarely under the actual hole. We trace it to the source and photograph it, which is how we avoid repeat visits.
