Roofing Services in London, ON
London Ontario roofing has to handle humid continental cold winters, hot humid summers, and severe weather including hail and the occasional tornado. Class 4 impact-resistant asphalt shingles dominate the architectural market. GAF, IKO, BP, and CertainTeed are the volume brands. London Building Division handles permits.
London's southwestern Ontario hail risk drives demand for impact-resistant shingles. Reputable roofers work directly with insurance adjusters and document damage with drone photography. The Western University community drives steady demand alongside the broader London economy.
Frequently Asked Questions
- Will hail justify Class 4 shingles?
- Yes, southwestern Ontario sees periodic hail events. Class 4 shingles offer durability benefits.
- How does ice damming affect London roofs?
- Heat loss through poorly insulated attics melts roof snow, which refreezes forming ice dams. R-60+ attic insulation prevents the damage cycle.
- How long does a re-roof take?
- A typical 2,000-2,500 sq ft asphalt re-roof takes one to two days for London crews.
