A fibreglass roof is one of the best choices for both homes and businesses. It’s rugged, waterproof, and can last for decades with the proper care. However, just like any other part of your property, it requires some attention to stay in top shape. Whether you’re a homeowner, a business owner, or a property manager, knowing how to maintain and repair fibreglass roofing can save you a lot of stress and money in the long run.
In this guide, you’ll find simple, practical advice straight from the best roofers in London. We’ll cover everything from cleaning and inspections to fibreglass roof repair and when to call in the experts. Let’s get started!
Why Choose Fibreglass Roofing?
Fibreglass roofing, also known as GRP (Glass Reinforced Plastic), is popular for a reason. It’s strong, lightweight, and completely waterproof. The seamless finish means there are no joins for water to sneak through. With proper care, fibreglass roofing panels can last 25 years or more.
But even the toughest roofs need a little TLC. Regular maintenance keeps your roof looking great and working hard, protecting your property from leaks and weather damage.
Simple Cleaning Tips for Your Fibreglass Roof
Cleaning is the first step in keeping your fibreglass roof in top condition. Dirt, leaves, and moss can accumulate over time, making your roof appear old and potentially causing damage if left unchecked.
How to clean your fibreglass roof:
- Use a soft-bristled brush or mop to sweep away loose debris.
- Mix mild detergent with water and gently scrub the roof surface.
- Rinse with a garden hose. Never use a pressure washer with hot steam, as this can damage the roof’s protective coating.
- Avoid harsh chemicals or abrasive tools.
How often?
Aim to clean your fibreglass roof twice a year, once in spring and once in autumn. If trees surround your property, you might need to clean more often to remove fallen leaves and twigs.
Regular Inspections: Catch Problems Early
You can’t always see your roof, but that doesn’t mean you should forget about it. Regular inspections help you identify minor issues before they escalate into major, expensive problems.
What to look for:
- Cracks or pinholes in the fibreglass surface
- Blisters or bubbles (these can let water in)
- Fading or chalky patches on the coating
- Water pooling or slow drainage
- Loose or damaged flashing around edges and joints.
Tip:
Set a reminder to check your fibreglass roof every six months. Take notes or photos to track any changes over time.
Maintaining Drainage and Gutters
A clean roof is only part of the story. Good drainage is just as important.
- Clear leaves, twigs, and debris from gutters and downpipes regularly.
- Check that water flows freely and doesn’t pool on the roof.
- Make sure drainage points are not blocked, as standing water can cause blisters or cracks in the fibreglass.
This is especially important for commercial properties, where blocked drainage can result in significantly higher repair bills.
Protective Coatings: Keeping Your Roof Strong
Every 5 to 10 years, your fibreglass roof will benefit from a fresh protective coating. This keeps it waterproof and protects against UV rays, which can cause fading and cracks over time.
Types of coatings:
- Gel coat: Easy to apply, gives a smooth finish.
- Acrylic paint: Lasts longer and offers extra protection.
Always follow the manufacturer’s instructions or consult with the best roofers in London for assistance with recoating. It’s a small job that can add years to your roof’s life.
How to Repair Minor Damage on Fibreglass Roofs
Even with reasonable care, small cracks or holes can appear over time. The good news? Most minor fibreglass roof repair jobs are simple if you catch them early.
Step-by-step repair guide:
- Clean the area: Remove dirt and debris from the damaged spot.
- Dry the surface: Ensure the area is completely dry before you begin.
- Sand lightly: Use fine sandpaper to roughen the area around the crack for better adhesion.
- Apply repair compound: Use a fibreglass repair kit to fill cracks or holes. Follow the instructions carefully.
- Seal the repair: Once dry, apply a coat of sealant or topcoat to prevent water from entering.
Important:
If you find significant cracks, blisters, or leaks, it’s time to call in the best roofers in London. They have the tools and experience to address larger problems safely and efficiently.
