An older city with older roofs
St. Catharines has some of the oldest housing of any city we cover (Statistics Canada, 2021):
- 71% of homes were built before 1981, and 33% before 1961 (Ontario: 49% and 23%).
- Only 5% were built in 2011–2021.
- 56% of households live in single-detached houses.
With housing that age, roofing problems tend to come from age rather than extreme weather: multiple layers of old shingles, chimneys and flashing that have been patched over the years, older decking, and attics built long before modern insulation standards.
A milder, lake-moderated climate
Between Lake Ontario and the Niagara Escarpment, the St. Catharines area has a gentler climate than most of Ontario. The nearest long-term Environment Canada station (Vineland) records about 112 cm of snow and 75 freeze-thaw days a year. That’s easier on roofs than Ottawa or Barrie, but still enough to open up old flashing and push water under worn shingles.
What older-home owners should know
- Expect a proper tear-off. On an older roof, removing old layers lets the roofer check the decking underneath.
- Look at the attic too. Poor insulation and ventilation shorten a roof’s life and cause winter ice at the eaves.
- Chimneys and flashing on older brick homes are the most common leak points. Roof leak repair
- Repair or replace? An honest free inspection is the best place to start.
