When it comes to exterior home protection, siding and windows often take the spotlight. But there’s a behind-the-scenes player doing just as much heavy lifting to protect your home from Colorado’s unpredictable weather: flashing.
What is Flashing?
Flashing is a thin, waterproof material—typically made of metal, rubber, or plastic—that’s installed around vulnerable areas of your home’s exterior. Think window and door openings, roof intersections, chimneys, and where siding meets horizontal surfaces like decks. Its job? To direct water away from seams, gaps, and joints—anywhere moisture might sneak into your walls.
Why It Matters in Colorado
With our freeze-thaw cycles, heavy snow, and sudden summer storms, Colorado homes are constantly exposed to moisture threats. Without proper flashing, water can get behind siding or under window frames, causing rot, mold, insulation damage, and even structural problems. Over time, undetected moisture can lead to expensive repairs that insurance may not always cover, especially if poor installation is to blame.
Even high-end siding and windows can’t do their job properly if they aren’t installed with well-placed, high-quality flashing. Flashing acts like the silent guardian, funneling water away and preserving your home’s structure and energy efficiency.
Common Flashing Mistakes
- Skipping It Entirely: Some builders try to cut corners and skip flashing altogether in less visible areas.
- Improper Installation: Flashing must overlap and be angled correctly to allow drainage—not trap water.
- Cheap Materials: Low-quality or incompatible flashing materials may break down over time or react poorly with surrounding materials, accelerating decay instead of preventing it.
