Roof Leak Repair in Windsor, Ontario
A water stain spreading across your ceiling almost never means the leak is directly above it — and that’s why so many homeowners waste money chasing the wrong spot before calling a real roof repair company. We handle cracked and missing shingles, failed flashing around chimneys and vent stacks, ice-damming leaks along the eaves, deteriorated pipe boots, valley leaks where two roof planes meet, sagging or soft spots in the decking, and leaks that only show up during wind-driven rain. If water is getting into your attic or ceiling, we track it down.
Our diagnostic process starts on the roof, not the ceiling. We walk the full roof surface checking shingle condition, flashing seals, fastener pattern, and valley and penetration points, then cross-reference that against where the stain is showing up inside — because water travels along rafters and sheathing before it drips, sometimes several feet from the actual entry point. On older Windsor roofs we also check attic ventilation and insulation, since poor airflow is a leading cause of ice-damming leaks that mimic a shingle failure.
A small roof leak left alone doesn’t stay small — it soaks insulation, rots decking, and eventually shows up as mold or a sagging ceiling, turning a $300 patch into a multi-thousand-dollar repair. Most people find us the same way: searching emergency roof leak repair after spotting a fresh stain during a storm, or looking for local roofing contractors after a home inspection flagged aging shingles. We also field a steady stream of calls from people who tried a handyman roofers fix from a big-box tutorial and made the leak worse.
Windsor sees its share of severe spring and summer storms rolling in off Lake St. Clair and Lake Erie, and wind-driven rain off the water is a leading cause of leaks that wouldn’t happen in a calmer climate — shingles that look fine in dry weather can still let water past the seal line when rain is hitting the roof sideways. Combined with our freeze-thaw winters, which loosen shingle adhesive and crack flashing sealant over time, Windsor roofs age faster than the manufacturer’s rated lifespan often suggests.

What Our Windsor Clients Say
Real feedback from Windsor-Essex homeowners we’ve helped with roof leak repairs.
Serving Windsor and Nearby Areas
We provide roof leak repair across Windsor, Forest Glade, Riverside, South Windsor, Walkerville, Sandwich, Tecumseh, LaSalle, Amherstburg, and Essex, on residential and light commercial roofs alike.
Windsor’s location at the meeting point of Lake St. Clair and the Detroit River means our storms often bring wind-driven rain that finds weaknesses a calmer rainfall never would, and our freeze-thaw winters put real stress on shingle seals and flashing year after year. Add in the older housing stock found throughout Walkerville and Sandwich, where original roof decking and multiple shingle layers are still common, and it’s easy to see why roof leaks here often need an experienced eye rather than a quick shingle swap.
Experienced Gutter Repair Specialists in Windsor
We repair asphalt shingle, cedar shake, and low-slope flat roofing systems, covering flashing failures around chimneys, skylights, and vent stacks, ice-dam damage along eaves, valley leaks, damaged decking, and soffit and fascia issues that let water track into the attic. We also handle commercial roof repairs on flat and low-slope membrane roofs for Windsor-Essex small businesses.
What separates us from other roof contractors is that we won’t quote a full re-roof when a targeted repair will genuinely last. We check the adjacent systems other roofers skip — attic ventilation, insulation depth, gutter backup — because a roof leak is often a symptom of one of those failing first. If your roof really is past its service life, we’ll say so plainly, with photos and a real explanation, not a scare tactic.

Frequently Asked Questions
What's included in a roof leak repair service call?
A typical call includes a full roof inspection to trace the actual source of the leak, an attic check for water tracking and ventilation issues, and a written quote for the repair before any work starts.
How much does roof leak repair cost in Windsor?
Most roof leak repairs in the Windsor area run between $150 and $800 for straightforward fixes like flashing or a small section of shingles. More involved repairs, including decking replacement or valley work, typically run $800 to $2,500. Emergency after-hours calls during active storms usually carry a premium on top of standard rates.
Should I repair my roof or replace the whole thing?
If the leak is isolated to one area and the rest of the shingles are in reasonable shape, a targeted repair is almost always the smarter first move. A full replacement usually only makes sense once a roof is past 20 to 25 years old, has multiple failure points, or has widespread decking damage — we'll show you photos either way.
How often should I have my roof inspected?
We recommend an inspection once a year, ideally in fall before winter storms and ice-damming season, plus a check after any major wind event. Catching a cracked shingle or lifted flashing early is far cheaper than repairing the water damage it causes later.
What are the warning signs of a roof leak?
Watch for water stains or discoloration on ceilings, peeling paint near the roofline, granules collecting in gutters or downspouts, daylight visible through the attic roof deck, and a musty smell in upper rooms or the attic. Any of these is worth a call before the next storm.
What should I do about a roof leak during an active storm?
Move furniture and place a container under the drip if it's safe to do so, and call us for emergency roof leak repair — we prioritize active leaks during storms and can tarp an exposed area to stop further damage until a permanent repair is possible.
Do commercial roofs need a different kind of repair than residential ones?
Yes — commercial roof repairs on flat and low-slope membrane systems require different materials and techniques than sloped shingle roofs, and leaks often travel further before showing up inside. We handle both residential and commercial roof repairs for Windsor-Essex properties.
Why should I call Windsor Handy Wizards instead of another roofing company?
We trace leaks to their real source instead of guessing, we use materials suited to Windsor's storm and freeze-thaw conditions, and we give straight repair-versus-replace advice backed by photos. Compare us to any other local roofing contractors on honesty and follow-through.
