Mississauga has 105 businesses listed under roof inspection and maintenance, ranging from one-truck operators who focus on repairs to larger crews that also handle full replacements. This category covers the ongoing care side of roofing: visual and physical inspections, minor repairs, gutter and flashing checks, moss or debris removal, and the kind of preventive work that catches problems before they turn into a leak in your attic.
What's typically included
A proper inspection covers the shingles or membrane, flashing around chimneys and vents, valleys, eavestroughs, soffit and fascia, and attic ventilation. Most contractors will check for granule loss, cracked or curling shingles, nail pops, and signs of water intrusion from the underside. Maintenance visits often bundle in gutter clearing, minor caulking or flashing repair, and removing branches or debris that trap moisture against the roof deck.
What to look for before hiring
Check that the company is insured and carries WSIB coverage for anyone climbing on your roof. Ask whether the inspection includes a written report with photos, not just a verbal summary. Get a sense of how they handle Mississauga's freeze-thaw cycles and ice damming specifically, since that's the issue most local roofs deal with each winter. A contractor who gives you options (patch now versus plan for replacement in a few years) is usually more useful than one who pushes a full re-roof on the first visit.
