Roof Repair in Windsor, ON

Roof repair in Windsor is defined by a climate that is deceptively demanding despite the city's reputation for mild Ontario winters. The key dynamic is not cold — it is freeze-thaw cycling combined with one of Ontario's heaviest ice storm exposures. Windsor's southerly position and Lake Erie moisture make it particularly susceptible to freezing rain events, where rain falls on surfaces already below freezing, creating ice dams and ice loading that asphalt shingles and flashings were not necessarily designed to handle. An ice storm in Walkerville can deposit 30–40mm of clear ice on a roof in a single event — enough weight to stress aged sheathing in the century-old homes along Devonshire and Kildare Roads.

The city's housing stock — with a median construction year of 1965 — means a substantial portion of Windsor roofs are approaching or have passed their first full replacement cycle. Three-tab asphalt shingles installed in the 1980s and 1990s have typical lifespans of 20–25 years; those roofs have been requiring replacement on an accelerating schedule through the 2010s and 2020s. The more recent architectural shingle generation, with 30–40 year warranties, is being specified across Windsor's renovation market but requires proper deck preparation in older homes where original 1×6 skip sheathing may need to be overlaid or replaced with OSB for proper nailing base.

Windsor's hot, humid summers add a second dimension to roof wear that northern Ontario cities don't experience as intensely. UV degradation at Windsor's latitude — combined with temperatures that can superheat south-facing shingle surfaces to 65–70°C on an August afternoon — accelerates granule loss and surface oxidation in asphalt shingles faster than in cooler climates. Algae and moss growth, facilitated by the region's humidity, is a common cosmetic and minor structural issue on north-facing roof planes in established Windsor neighbourhoods with mature tree canopy.
