Some of the most common commercial and condo roofing issues in Hamilton include drainage problems, flashing failures, seam wear on low-slope systems, standing water, and deterioration caused by freeze-thaw cycles and seasonal weather exposure. On larger properties, small weaknesses can affect more than one unit or common area if they are left unaddressed. Aucoin Roofing looks at the roof as a full system so we can identify where the real risks are and recommend the most practical next step for protecting the building.
