FRP (Fiberglass Reinforced Plastic) roofing is known for being tough, lightweight, and resistant to corrosion. But that doesn’t mean it’s completely maintenance-free. Many people believe certain myths about maintaining FRP roofing, which can lead to unnecessary damage or costly mistakes. In this article, we’ll break down common FRP roofing maintenance myths, explain what actually works, and provide practical advice to help you extend the life of your roof.

Myth #1: FRP Roofing Doesn’t Need Maintenance

Reality: Regular Checkups Keep It in Top Shape

It’s true that FRP roofing is low-maintenance, but that doesn’t mean it requires zero upkeep. Over time, exposure to the elements can cause minor wear and tear. If left unchecked, small issues can turn into bigger problems.

What You Should Do:

• Inspect your roof twice a year to catch small cracks, loose fasteners, or buildup of dirt and debris.
• Clean it with mild detergent and water to prevent dirt from affecting the protective coating.
• Check and replace sealants and fasteners if they show signs of wear.

Myth #2: High-Pressure Washing Is the Best Way to Clean FRP Roofing

Reality: Too Much Pressure Can Damage the Surface

Some people believe blasting an FRP roof with a pressure washer will keep it clean. The truth is, high-pressure water can wear down the protective coating and cause damage over time.

Better Cleaning Methods:

• Use a soft-bristle brush and mild soap to remove dirt and grime.
• If you must use a pressure washer, keep it below 1000 PSI and don’t hold the nozzle too close to the roof.
• Avoid harsh chemicals or abrasive cleaners that can weaken the surface.

Myth #3: FRP Roofing Can’t Be Repaired

Reality: FRP Roofing Can Be Fixed with the Right Materials

Some people think that if an FRP roof is damaged, it needs to be completely replaced. The good news is that most minor damage can be repaired easily, saving you time and money.

How to Fix Minor Damage:

• Small cracks or holes? Use FRP-compatible sealant to patch them up.
• Larger issues? Apply a fiberglass patch with resin and hardener, then smooth it out.
• Check for loose edges or stressed areas and reinforce them before they worsen.

Myth #4: FRP Roofing Can’t Handle Sun Exposure

Reality: UV Protection Keeps It Strong

Yes, long-term sun exposure can weaken some materials, but quality FRP panels come with built-in UV protection. That said, UV resistance can wear down over time, so proper care is key.

How to Maintain UV Protection:

• Choose UV-resistant FRP panels for long-lasting durability.
• Apply a UV-protective gel coat every few years if the surface starts to fade.
• Keep your roof clean—dirt buildup can trap heat and speed up wear.

Myth #5: All FRP Roofing Is the Same

Reality: Quality Varies by Manufacturer

Not all FRP panels are created equal. The strength, durability, and weather resistance of an FRP roof depend on its resin composition, fiberglass content, and manufacturing process.

What to Look for in High-Quality FRP Roofing:

• Multi-layered panels with a high glass-to-resin ratio for better strength.
• Fire-resistant and chemical-resistant panels for added safety.
• Panels that meet industry standards like ASTM D638 for consistency and performance.

Best Practices for FRP Roofing Maintenance

To keep your FRP roof in the best possible condition, follow these simple maintenance tips:

1. Inspect your roof regularly – Check for small cracks, leaks, or loose fasteners at least twice a year.
2. Keep it clean – Remove dirt, algae, and debris to maintain performance.
3. Reapply protective coatings – If your roof’s UV protection is fading, add a fresh gel coat.
4. Ensure structural support – Make sure the roof isn’t carrying excess weight or experiencing stress.
5. Fix small problems early – Address minor damage right away to prevent costly repairs later.

Taking care of an FRP roof isn’t complicated, but avoiding common maintenance myths can make all the difference. Regular inspections, gentle cleaning, and prompt repairs will keep your FRP roofing strong, weather-resistant, and long-lasting for years to come.
