What Causes Roof Stains in Wisconsin?

Wondering why your roof has suddenly developed noticeable stains? Factors such as moisture, humidity, and the local climate create an ideal environment for roof staining.

1. Wisconsin’s humid climate can lead to algae growth forming dark streaks or black stains on the roof’s surface.
2. Damp conditions and limited sunlight also cause moss and lichen, which appear as green patches or white and green spots.
3. Heavy winter snow and rainfall can lead to excessive moisture accumulation that creates a favorable environment for mold and mildew when it doesn’t dry properly.
4. Overhanging tree branches that create shade and falling leaves make the roof more likely to retain moisture and develop stains.
5. Some areas of Wisconsin have higher pollution levels. Pollutants, dust, and other airborne particles settle on roofs, creating a layer that promotes stains and discoloration.

Roof Stain Cleaning and Removal Techniques

Homeowners have several options for removing roof stains. Some are DIY, while others require professional services.

Note: If you decide to perform roof maintenance or cleaning yourself, it’s essential to exercise caution, follow safety guidelines, and familiarize yourself with proper techniques to avoid injury and minimize risk.

• Mild stains can often be removed with a soft-bristle brush and a mixture of water and mild detergent. Some people prefer a solution of one part bleach and three parts water. Let the formula sit for about 15 to 20 minutes and then rinse thoroughly with water. For more stubborn stains, a professional roof cleaner can use pressure washing to clean the roof’s surface without causing damage.
• Roof cleaners often employ biodegradable and environmentally friendly cleaners to target and eliminate moss, algae, and lichen.
• You might consider installing zinc or copper strips near the roof ridge. When it rains, the water runs over the strips, which then release ions that inhibit algae growth. Protective coatings can also be a barrier against staining agents.

Routine professional maintenance and repair can also play a critical role in preventing roof stains, and regular inspections by an experienced roofer can identify the early signs of staining. Quick repair of damaged or deteriorated areas ensures a properly functioning roof that minimizes the risk of water intrusion or subsequent staining.

Lastly, if you’re replacing your existing roof, talk to your roofing contractor about whether certain materials are more stain resistant than others. For instance, metal roofs are generally highly resistant to staining, as are certain types of asphalt shingles with built-in stain inhibitors. Synthetic roofing materials like composite or polymer-based shingles also offer increased stain resistance.
