When maintaining your roof, one important factor to keep in mind is that it is constantly exposed to organic growth such as moss, fungi, and algae. Certain roofing materials are more prone to these issues, while others — like metal roofing — are less susceptible. In many cases, homeowners attempt to clean their roofs themselves, but it can quickly become a time-consuming and labor-intensive task.
If you need help removing moss or fungi from your roof, RAM Roofing & Exteriors proudly serves homeowners throughout Bucks County, PA and Montgomery County, PA. Before deciding whether to handle the cleaning yourself or call a professional, it’s important to understand how different roofing materials should be treated.
Cleaning Moss and Algae From Asphalt Shingles
Asphalt shingles are one of the most common roofing materials in Pennsylvania. Many asphalt roofs are over a decade old, making them more vulnerable to moss and algae growth.
When moss or algae develop, you may notice:
- Dark streaks or stains
- Shingles that appear weathered
- Granule loss
- Missing or weakened shingles
Moss can gradually break down the protective outer granulation of asphalt shingles, shortening the lifespan of your roof. Routine cleaning helps extend the life of your roofing system.
A diluted bleach-and-water solution is often used to treat asphalt shingles safely. It’s critical not to mix bleach with other chemicals, as this can create harmful fumes. Gentle application and proper rinsing are essential to avoid damaging the shingles.
If you’re unsure about the safest cleaning method, professional roof inspections can identify damage and determine whether cleaning or roof repair services are necessary.
Cedar Roofs Require Extra Care
Cedar roofing is beautiful and highly sought after, but it requires more maintenance than many other materials. While cedar shingles can last a long time, they are still natural wood products and prone to organic breakdown.
Cedar roofs may experience:
- Natural fiber deterioration
- Moss and mildew buildup
- Surface discoloration
When cleaning cedar, it’s important to use gentle treatments. Power washing is often discouraged because it can strip away the natural resins that protect the wood and contribute to its visual appeal.
Specialized cleaning solutions designed for wood roofing are typically recommended to preserve the material while removing harmful growth.
Cleaning Tar and Cement Roofs
Tar and cement roofing systems are generally more durable when it comes to cleaning. These materials can typically withstand power washing and stronger cleaning agents compared to shingle-based systems.
However, while cleaning these roofs, you should inspect for:
- Bubbling or blistering
- Cracked seams
- Splits or punctures
- Areas where the material is separating
These signs may indicate the need for more than just cleaning. In such cases, a professional roof replacement or targeted repair may be required.
