Heavy Rain, Moisture & Prolonged Wet Conditions
Vancouver's frequent rainfall can expose small weaknesses in roofing systems and allow moisture to enter areas that are difficult to see.
Seal Degradation
Caulk and sealants around vents, skylights and chimneys can deteriorate through UV exposure and repeated moisture. When seals fail, water can enter around roof penetrations and create the need for proper repair or flashing replacement.
Hidden Leaks
Water does not always appear directly below the point where it enters the roof. It can travel along roof framing before becoming visible inside the home, meaning a small leak can remain unnoticed while moisture damage develops.
Roofing tip: A visible ceiling stain may not identify the actual point where water entered the roof. Finding the source is an important part of effective roof leak repair.
