The answer to 'ridge vent algae growth' is that algae growth on ridge vents is a common problem caused by moisture, lack of sunlight, and organic debris buildup. The algae can cause the ridge vent to become discolored, unsightly, and potentially reduce its effectiveness in ventilating the attic. To address this issue, you can try cleaning the ridge vent yourself, but in some cases, it may be necessary to call a professional roofing contractor.
The first step in addressing ridge vent algae growth is to identify the root cause. Excess moisture, lack of sunlight, and organic debris buildup can all contribute to the problem. Once the cause is identified, you can take steps to address it, such as improving attic ventilation, trimming nearby trees or bushes, or cleaning the ridge vent.
