Several top Markham roofers, including Cherry & Clark (GAF Master Elite), Guildwood (IKO/CertainTeed/BP), and Unique Roofing (GAF/CertainTeed), hold these designations. Before freezing weather hits Ontario, clear your gutters and downspouts of all fallen leaves and twigs. Blocked drainage channels cause water to back up under the bottom edge of your shingles, creating massive ice dams during winter freeze-thaw cycles. Ensure your soffit intakes are completely unblocked to allow continuous air movement through your attic space. Dark stains on upper ceilings, damp structural beams, or a regular buildup of winter attic frost usually point to poor attic ventilation underneath the roof deck.
