Roof Inspection & Maintenance in Ontario
Roof inspection and maintenance covers the routine work that keeps a roof from turning into a bigger problem: checking shingles, flashing, and seals for wear, clearing gutters and downspouts, spotting early leaks around vents and chimneys, and documenting the roof's condition before it becomes an insurance issue. In Mississauga, this matters most after winter, when ice damming and freeze-thaw cycles loosen flashing and crack shingles, and after summer storms, when wind and hail can lift or bruise shingles without leaving obvious signs from the ground. We've found 13 businesses in this category serving the city.
A good inspection isn't a five-minute walk-around from the driveway. Look for a contractor who gets on the roof (or uses a drone with clear photo documentation), checks the attic side for moisture and ventilation issues, and gives you a written report with photos, not just a verbal "looks fine." Ask whether the inspection fee is credited toward any repair work, what their maintenance plan includes (gutter cleaning, resealing, minor shingle repair), and whether they carry liability insurance and WSIB coverage, since anyone working at height on your property should. Be wary of anyone who shows up unsolicited after a storm pushing immediate full replacement before a real inspection has happened.
Our scoring weighs factors like verified licensing and insurance, how consistently a company documents its inspections, responsiveness to quotes, and patterns in customer feedback around follow-through and pricing honesty, so you're not just going on a star average.

Common questions about roof inspection & maintenance
- How much does a roof inspection cost in Mississauga?
- A standalone visual inspection typically runs somewhere in the range of free (offered as a lead-in to estimate repair work) up to around $150-$400 for a detailed inspection with a written report and photos. Drone or infrared inspections for larger or steeper roofs tend to cost more. If you're already getting a repair quote, many contractors fold the inspection fee into that estimate.
- How often should a roof be inspected?
- A general rule is once a year, ideally in spring after the freeze-thaw season, plus a check after any major wind or hail event. Roofs older than 15-20 years, or ones with known problem spots like valleys or chimney flashing, benefit from twice-yearly checks.
- What does a roof maintenance visit actually include?
- Typically: clearing debris and checking gutters and downspouts for proper drainage, resealing around vents, pipes, and flashing, checking for lifted or missing shingles, looking for moss or algae growth, and an attic check for signs of moisture, mold, or poor ventilation. You should get a written summary, not just a thumbs-up.
- How do I know if a roofing contractor's inspection is trustworthy?
- Ask for photo documentation rather than a verbal summary, confirm they're insured and WSIB-covered for work at height, and check whether their recommendations match what's visible in the photos rather than jumping straight to full replacement. A contractor willing to explain what's minor versus urgent, in plain terms, is usually a good sign.
