Roof leaks have a wide range of potential causes. The most common problems include weather damaged or missing shingles or tiles, cracks in flashing material, insufficient sealing around a skylight or dormer window, water backup resulting from a clogged gutter and failure of a seal in one of the “valleys” formed when two planes of your roof come together. Other possible causes include cracking at the base of a roof vent and cracks in your chimney. Some roofs can also develop leaks if you walk on it repeatedly.
Each potential source of a roof leak in you Coquitlam home has its own typical underlying causes. For example, damaged or missing roof shingles are usually caused by age-related deterioration, high winds and/or heavy downpours.
