A Small Damage Can Signal a Big Problem.
Visible damage is almost always a symptom of a deeper failure within the roof system. The shingle you can see lifting isn't the problem; it's the evidence of a deeper issue. What matters is what's happening underneath: it could be failed underlayment, rotted decking, compromised flashing, or a ventilation imbalance that's been trapping moisture for months.
Active roof leaks
Water stains, drips, or damp spots on ceilings and walls
Missing or lifted shingles
Wind-blown tabs that expose the underlayment to UV and rain
Hail and storm damage
Bruised shingles, dented vents, and damaged flashing after a weather event
Flashing failures
Leaks around chimneys, skylights, and plumbing vents — the most common leak source
Chimney or skylight flashing leaks
Failed or improperly sealed flashing allowing water to enter at roof penetrations
Pipe boot/roof vent failure
Cracked or deteriorated rubber seals around vents leading to slow, hidden leaks
Ice dam-related damage
Water backing up under shingles due to freeze-thaw cycles, causing interior leaks
Age-related wear
Curling edges, granule loss, and brittleness on roofs 15+ years old
Animal damage
Raccoons, squirrels, and birds creating entry points at soffits and ridges
The hidden damage rule:
Water travels along the path of least resistance—across rafters and underlayment—before it ever shows up as a ceiling stain. The actual roof defect may be metres away from where the interior damage appears. This is why a ground-level inspection misses almost everything that matters.
The Advanced Level Roofing Repair Process
Every repair begins the same way: find the real source before touching a single shingle. Our process is systematic, transparent, and designed to give you a lasting fix, not a patch that sends you back to square one next season.
01 | Meticulous Inspection To Find the Source
We get on the roof and into the attic. We trace the leak to its actual source, not just the most obvious spot. High-resolution photos document every finding before any work begins.
02 | Systematic Deconstruction To Expose the Damage
We remove the surrounding materials to expose the full extent of the damage. There’s no guesswork. We discuss with you what we've found and give you an honest Repair vs. Replacement assessment.
03 | System Rebuild — IKO Layers & Code Compliance
New IKO ice-and-water shield. New underlayment. New flashing at every affected penetration. New shingles colour-matched to your existing roof. Every layer is installed to code and according to manufacturer’s specifications.
04 | Final Validation & Cleanup
We complete a final quality inspection, confirm the fix is watertight, and hand over your written inspection report and workmanship warranty. Magnetic nail sweep of the full yard. Site left cleaner than we found it.
What a Proper Roof Repair Includes
Repair or Replace? We'll Tell You the Truth.
A lot of contractors will repair a roof that should be replaced simply because “a repair is a sale today”. We give you an honest assessment every time. If fixing the visible damage won’t extend the roof’s functional life, we’ll tell you. And explain exactly why roof replacement is the more economical long-term decision.
30%
The replacement threshold
When repair estimates exceed 30% of the cost of a full replacement on a roof older than 15 years, replacement is almost always the more economically sound decision. We calculate this for you upfront.

Here’s why home owners trust us with their homes...
SANDRA K. , McKenzie Towne, SE Calgary
Three different companies came out and each one threw caulk at the flashing around our chimney. It leaked again within six months every time. Advanced Level Roofing pulled everything back, found that the chimney saddle had completely failed and the decking behind it was rotted through. They rebuilt the whole section properly. That was two winters ago and not a single drip — including through a hailstorm.
Blair Loney , Calgary
From first contact to job complete, Advanced Level Roofing has been courteous, efficient, and professional. Despite our obvious need for a new roof, their associate wasn't pushy or overbearing, and provided his best price as well as a creative payment structure. ALR was willing to work with us on the initial deposit because we had been burned years earlier by a less-than-stellar contractor. Communication throughout the job was excellent and my questions were answered promptly by text, email or phone. All insurances were in place and WCB compliance was guaranteed. The entire job, including old material disposal, was wrapped up in a single day. Our yard was spotless and the new shingles looked amazing. Highly recommended.
Jill Caine , Calgary
Everything was seamless, from setting up the financing, to being informed before the work, to the work itself and the final inspection report with pictures of the completed job. The replacement actually happened on a day we were out of town, and you couldn't even tell they had been there when we got home except for the beautiful new roof.
