Some of the most common causes of roof leaks in Brantford include damaged shingles, worn or failed flashing, ice damming, roof-to-wall transitions, and aging sealants around penetrations like vents or chimneys. Weather also plays a big role. Snow, freeze-thaw cycles, wind, and heavy rain can all expose weak points in the roof over time. At Aucoin Roofing, we focus on finding the actual source of the leak rather than just repairing the area where the water shows up inside.
