Those dark streaks are likely roof algae, a common issue in our area due to humidity. While it starts as a cosmetic concern, it can trap moisture and slowly degrade your shingles, shortening their lifespan. We recommend a professional roof cleaning to remove the algae safely without damaging the shingles, followed by an inspection to check for any underlying wear or potential leak points, especially in the roof valleys.

Roof valley leaks are a frequent repair for us in Ewing. The solution depends on the extent of the damage. Our process starts with a detailed roof inspection to assess the valley flashing and surrounding shingles. Often, we can perform a targeted roof repair by resealing or replacing the valley flashing. If the leak has caused widespread rot or the roof is near the end of its life, we'll discuss if a roof replacement or reroofing is a more cost-effective, long-term solution.

Proper exterior systems work together to protect your home. For leaks, correctly installed gutters and downspouts are crucial—they channel water away from your roof edge and foundation, preventing overflow that can back up under shingles and into roof valleys. For siding, quality installation and repair maintain a tight seal on your walls, which prevents wind-driven rain from getting behind the exterior and causing moisture issues that can eventually affect the roof structure. We often address these as part of a holistic exterior assessment.
