Proper siding installation creates a critical protective barrier. In Seattle's wet climate, it works in tandem with your roof system to direct water away from your home's structure. By ensuring tight integration with roof flashings and providing a dry wall surface, quality siding reduces the overall moisture load that can contribute to moss growth on your roof and corrosion of metal components.

If you're dealing with roof flashing corrosion, check the siding directly below and adjacent to roof valleys, chimneys, and vents. Look for stains, soft spots, warping, or mold on the siding surface. These are often signs that compromised flashings are allowing water to seep behind your siding. Prompt repair of both the flashing and the affected siding is crucial to prevent rot and structural damage common in our local climate.

In Seattle, a full replacement is often recommended when frequent repairs are needed, the substrate (the wall behind the siding) shows signs of rot from chronic moisture exposure, or the existing materials can no longer be effectively sealed. Replacement allows us to install modern, water-resistant barriers and integrate them perfectly with your roofing system, offering a comprehensive, long-term solution against moss-promoting moisture and corrosion.
