Roofing questions Ontario homeowners ask us.
Most Ontario roofs benefit from an inspection twice a year — ideally spring and fall — and after any major storm. Older roofs may need more frequent checks. Cairns Roofing offers a free inspection so you know exactly where your roof stands before any work begins.
