Moisture damage spreads quickly

Once water gets behind the trim, it soaks into the wall sheathing and framing. Left unchecked, hidden moisture leads to mold, rot, and costly repairs. In our rainy climate, even a small gap can cause big problems over time.

Proper window and door flashing in this area protects the entire wall assembly. A tight seal stops cold drafts, lowers energy bills, and keeps out insects and pollen.

Protecting your home's exterior

The rotting trim you see isn’t just a surface issue. It shows that water is getting between your window frames and siding, damaging the sheathing behind it. Properly installed flashing directs rain away, protecting your home’s exterior from decay. It’s the hidden shield that keeps your walls dry long after a storm.

We replace old caulking and rusted metal with custom-bent aluminum or galvanized steel. This is tucked under the siding and over the window flange in a shingle pattern. This layered window and door flashing in Vancouver creates a drainage plane that lets gravity do its job. You get a watertight exterior that protects your siding and paint, stopping rot before it spreads to the framing.

Local climate challenges

Homes near Deer Lake are in a microclimate where damp air collects against the hillside, keeping outside surfaces wet for long periods each winter. This constant moisture, along with the mix of old lakefront bungalows and newer homes, means flashing details often fail first. A small leak can quickly lead to peeling paint and soft trim.

The older wood-framed windows in this area depend on their exterior flashing to last through our rainy season. Without a continuous metal cap over the top trim and step flashing down the sides, wind-driven rain can get behind the siding. A proper installation considers Deer Lake’s heavy exposure by overlapping every joint so water can only move down and out, never in.

Flashing installation in Deer Lake

Flashing around a window or door starts with the rough opening. We use a self-adhered membrane tape that covers the sill and goes up the sides. This tape works with the building paper to create a second layer that helps keep water out behind the siding.

Next, we place a sloped metal pan flashing at the sill. This has end dams to direct water away from the wall. After we install the window unit, we add a head flashing piece that overlaps the top flange and goes under the building paper above. This setup ensures that every joint directs water outward.

We then apply side flashings at the sides of the opening. The bottom of each side flashing overlaps the sill pan, and the top goes under the head flashing. For Deer Lake’s damp climate, we choose 26-gauge aluminum with a baked-enamel finish and use stainless steel fasteners to avoid rust and streaks.

Moisture management in Deer Lake

In Deer Lake’s wet climate, the building must manage moisture all the time. A drainage layer behind the siding lets any water that gets in flow down and out safely. At each window and door, our flashing components connect to this layer without blocking it.

The sill pan flashing creates a sloped surface that directs water out over the siding below. Its upturned back leg stops water from rising back up. The head flashing overlaps the window and goes under the weather-resistant barrier, so water from above is directed outward.

Because wind-driven rain from the lake can push moisture up, all flashing overlaps are made to resist that pressure. Self-adhered flexible tape at the sides provides an extra seal that doesn’t depend only on the head lap, keeping the structural sheathing dry even in severe weather.
