Starter shingles are specially designed roofing materials installed at the edges of a roof before the main shingles are applied. Their purpose is to provide a sealed base that prevents wind uplift and water infiltration at vulnerable roof edges. In rainy and windy climates like Vancouver, starter shingles are essential for ensuring proper roof sealing and long-term performance. They create a uniform edge that supports the first row of shingles and enhances overall system durability.
