How to Clean Roof Stains | Roofing Company Oakland County, MI

Dark spots on your roof can destroy your curb appeal, and they do not go away on their own. Roof stains may look like black, moldy streaks, or they may look like dark patches on the roof. Either way, there are some steps you can take to rectify the situation and preserve the beauty of your roofing. Check out this guide for how to clean roof stains.

Identify the Source of Roof Stains

Unfortunately, roof stains are usually an indication that your roof needs to be repaired or replaced. If you have black streaks on the north or west side of your roof, it may look like mold. In reality, those black marks are from algae that is growing on the shingles. Most roof shingles are treated with algaecide that can last for 10+ years. If you have an older roof though, the algaecide may have worn away.

If you have a dark area of shingles, that may be a weak area on your roofing. Moisture gets trapped below the shingles and cannot evaporate like it does on the rest of the roof. Assuming the rest of the roof is in good condition, you would only need a roof repair for this – not a complete roof replacement.

Provide Temporary Treatment for the Problem

If you are dealing with algae, you can have your roof cleaned and re-treated as a temporary solution. This may extend your roof’s life for a few years. A roof cleaning company will remove the algae from the shingles and apply a new layer of algaecide. The earlier this happens, the better. Algae can grow rapidly, and the longer you leave it alone, the more it costs to remove.
