As summer heat and humidity intensify across Florida, PRO Roofing, one of the state’s most trusted roofing contractors, is alerting homeowners to the increasing threat of moss and algae buildup on roofs. The company’s latest blog article, “How to Stop Moss and Algae From Damaging Your Roof This Summer,” provides critical insights into the causes of this seasonal issue, as well as preventive and treatment strategies that protect roof longevity and home value.

Moss and algae not only affect the appearance of a roof but also compromise its structural integrity. As they take hold, these organic materials can trap moisture, loosen shingles, and lead to mold or rot—problems that can become serious if not addressed in a timely and effective manner.

Common Causes of Moss and Algae on Florida Roofing Systems

Florida's humid climate, combined with heavy rainfall and frequent shade from vegetation, creates optimal conditions for moss and algae to thrive. Moss tends to develop in areas with limited sun exposure and can retain moisture against roofing materials. Algae, often appearing as black or dark green streaks, can spread rapidly during the summer months and feed on the limestone filler found in many asphalt shingles.

These types of growth not only stain roofs but also break down protective layers, potentially reducing the overall lifespan of the roofing system.

Recommended Treatments from Professional Roofing Contractors

In addition to professional services, PRO Roofing encourages homeowners to consider safe, effective methods for removing moss and algae on their own—when conditions allow:

• Apply Vinegar or Bleach Solutions: A diluted 50/50 mixture of water with white vinegar or bleach can be used to spot-treat growth. Application should be done carefully, followed by a thorough rinse to protect surrounding plants.

• Install Zinc or Copper Strips: These metal strips, placed near roof ridges, release ions during rain that prevent future growth.

• Trim Overhanging Branches: Reducing the amount of shade on a roof allows for faster drying and less moisture accumulation.

• Avoid Pressure Washing: While tempting, high-pressure cleaning methods may damage shingles and void manufacturer warranties.

Homeowners are encouraged to consult with licensed roofing contractors before attempting any DIY method, especially in the case of steep or aging roofs.

Expert Insight from PRO Roofing Leadership

“Moss and algae can be far more than cosmetic concerns. On a recent project in Clearwater, moss buildup had lifted a section of shingles, allowing water to seep into the attic and cause extensive internal damage,” said Melissa Parker, owner of PRO Roofing. “What might have been a simple $200 cleaning turned into several thousand dollars in repair costs due to delayed maintenance.”

“Simple actions such as tree trimming and the use of zinc strips are highly effective when applied early. If using any chemical treatment, it is critical to apply it safely, wear proper protection, and rinse surrounding areas thoroughly. However, safety must always come first—roofs are best evaluated and treated by qualified roofing contractors when possible.”

Long-Term Preventive Measures to Extend Roof Lifespan

Prevention remains the most effective strategy when protecting roofing systems from environmental damage. PRO Roofing recommends the following steps to maintain durable and clean roofs throughout Florida’s long summers:

• Schedule Annual Roof Inspections: Regular check-ups by trained roofing contractors can detect issues before they escalate.

• Maintain Clean Gutters and Downspouts: Blocked drainage causes water pooling that accelerates moss and algae growth.

• Upgrade to Algae-Resistant Shingles: Modern materials are designed to resist staining and microbial growth for long-term performance.

• Ensure Proper Ventilation: Adequate attic and roof ventilation reduces internal moisture and helps roofs dry more quickly after rain.

These practices are critical for homeowners aiming to preserve curb appeal, avoid premature roof replacement, and minimize ongoing maintenance costs.
