Flat roofs in eastern Ontario
Eastern Ontario runs from the Bay of Quinte to Ottawa and the St. Lawrence. Winters are colder than in the GTA, with deep frost, heavier snow and long freeze–thaw seasons.

What this means for your roof
Snow loads are moderate here. Most damage comes from freeze–thaw cycles, ice at the drains in late winter and heavy summer rain.
Whatever the climate, most leaks start at details: seams, flashings, drains, vents and skylights. See roof problems for causes and fixes.
