London’s weather is harder on roofs than most of Ontario
London sits in the lake-effect snowbelt east of Lake Huron. Environment Canada’s normals for London International Airport show:
- 194 cm of snow a year. Only Ottawa and Barrie get more among the cities we cover.
- 1,012 mm of total precipitation a year, the wettest of any station we track.
- About 1.2 days a year with hail, the most of any city we cover, plus 28 thunderstorm days.
- 86 days a year when temperatures cross freezing.
In practice that means two seasons of roof problems. Winter brings ice dams and meltwater backing up at the eaves (roof leak repair). Summer brings hail and storm damage that isn’t always visible from the ground (emergency roof repair).
London homes
About half of London’s homes (52%) were built before 1981, in line with Ontario overall, and 22% before 1961 (Statistics Canada, 2021). London also has a large rental market (42% of households rent), so roof repairs on older rental houses are common too.
Permits in London
The City of London lists “re-shingling a roof” among projects that don’t need a building permit. Changes to the roof structure do. City of London: before you apply for a building permit
After a hailstorm
- Look from the ground for dented vents, eavestroughs or downspouts. If those are marked, the shingles may be too.
- Photograph everything, including hail on the ground if you can.
- Book a free roof inspection. Hail bruising often isn’t visible without getting on the roof.
- Talk to your insurer. Sudden hail damage is treated differently from wear and tear.

London roofing questions
How does lake-effect snow affect London roofs? More snow on the roof means more meltwater, and more chance of ice dams when attic heat melts it. Eave protection, attic insulation and ventilation are the defence.
What should I do after hail damage? Photograph it, avoid climbing on the roof, book an inspection and call your insurer. See the steps above.
Do I need a permit to re-shingle in London? No. The City lists re-shingling among projects that don’t need a permit.
