Reasons Why Fibreglass Roofs Leak and How to Identify Them
Leaking flat roofs can cause extensive damage to the underlying structure if not addressed promptly. It’s important to identify the cause of the leak before proceeding with repairs. Here are some common causes of fibreglass roof leaks and how to identify them:
Punctures
Punctures in a fibreglass roof can occur due to various reasons, such as falling debris or foot traffic. Look for visible holes or tears in the roof surface. Inspect the surrounding area for any signs of impact, like dents or dislodged materials.
Wear and Tear
Over time, fibreglass roofs can deteriorate due to exposure to harsh weather conditions and UV rays. Inspect the roof for signs of fading, cracking, or blistering. Pay attention to areas that receive the most direct sunlight or are prone to pooling water, as these are common areas for wear and tear.
Leaks in Gutters
Leaking gutters or faulty downspouts can lead to water seeping into the roof. Check for signs of water stains or damage near the gutters and downspouts. Regularly clean and maintain the gutters to prevent clogs and ensure proper water drainage.
Poor Installation
Improper installation techniques can compromise the integrity of a fibreglass roof. Look for signs of poor workmanship, such as uneven surfaces, gaps, or loose joints. If your roof was recently installed and you suspect poor installation, contact the original roofer to address any issues under warranty.
The key to preventing further damage from roof leaks is early detection. Regular inspections and maintenance programs can help identify and eliminate sources of leaks before they cause significant damage.
If your fibreglass roof is still under warranty, it’s worth checking the coverage to determine if the damage is eligible for repair. Remember, addressing the underlying cause of the leak is essential for a successful and long-lasting repair.
| Causes of Fibreglass Roof Leaks | Identification |
|---|---|
| Punctures | Visible holes or tears, impact marks |
| Wear and Tear | Fading, cracking, blistering |
| Leaks in Gutters | Water stains, damage near gutters and downspouts |
| Poor Installation | Uneven surfaces, gaps, loose joints |
Benefits of Repairing a Fibreglass Roof versus Replacement
When it comes to fibreglass roofs, repair can often be a more cost-effective option than replacement. While a new fibreglass roof offers benefits such as improved energy efficiency and a long lifespan, the cost involved in completely replacing the roof can be a significant deterrent. Repairing a fibreglass roof, especially through pre-emptive repairs, can extend its lifespan by a decade or more, saving you the expense of a full replacement.
Benefits of Roof Repair:
- Cost-effective solution: Repairing specific areas of the roof is a more cost-effective option, especially if the roof was recently installed or if the underlying structure is still intact. Instead of the high cost of a complete replacement, you can address the damaged areas specifically, saving money in the process.
- Longer lifespan: Properly repaired fibreglass roofs can last for many more years, giving you peace of mind knowing that your roof is protected and secure. Pre-emptive repairs can help prevent further damage and extend the overall lifespan of your roof.
- Preserves the existing structure: By repairing your fibreglass roof instead of replacing it, you can keep the existing supporting structure in place, saving on the cost and time associated with a full tear-off and replacement. This is especially beneficial if the underlying structure is still in good condition.
It’s important to weigh the pros and cons of repair versus replacement before making a decision. Repairing your fibreglass roof can often be a cost-effective solution that not only saves you money but also extends the life of your roof, providing long-term benefits.
Comparison of Fibreglass Roof Repair and Replacement Costs
| Repairing a Fibreglass Roof | Replacing a Fibreglass Roof |
|---|---|
| Lower cost | Higher cost |
| Preserves the existing structure | Requires a complete tear-off and replacement |
| Extends the lifespan of the roof | Provides a brand new roof |
| Can be targeted to specific areas of damage | Involves replacing the entire roof surface |
Types of Leaks in Fibreglass Roofs and How to Repair Them
Different types of leaks can occur in a fibreglass roof, and each requires a specific repair method. It’s essential to identify the type of leak accurately to ensure effective repairs. Here are some common types of leaks in fibreglass roofs and how to repair them:
Punctures
Punctures can happen due to various reasons, such as falling debris or foot traffic on the roof. To repair a puncture, you can use a fibreglass repair kit. Start by thoroughly cleaning the damaged area and allowing it to dry. Apply the repair kit’s adhesive and fibreglass patch over the puncture, ensuring a tight seal. Finally, apply a topcoat of protective sealant to prevent further damage and ensure the roof remains watertight.
Roofing Membrane Wear, Cracks, and Multiple Leaks
In cases where the fibreglass roof shows signs of wear, extensive cracking, or leaks in multiple regions, a more comprehensive repair approach may be necessary. Depending on the severity of the damage, you might consider a full roof replacement or an overlay/over deck system. Consult a professional roofer to assess the extent of the damage and determine the most appropriate repair method.
Leaking Gutters
Before repairing any leaks in the fibreglass roof, it’s crucial to address any issues with the gutters. Leaking gutters can exacerbate roof leaks, leading to further damage. Inspect and fix any gutter leaks before proceeding with repairs to ensure the effectiveness of the fibreglass roof repair.
Poor Installation
Poor installation practices can also contribute to roof leaks. If you suspect that the roof’s original installation was done incorrectly, it’s best to contact the original roofer for assessment and repairs. They will have the necessary expertise to identify and address any installation-related issues that might be causing leaks.
When repairing leaks in a fibreglass roof, it is essential to assess the extent of the damage and choose the appropriate repair method accordingly. If you are unsure or the damage is significant, it’s always recommended to consult a professional roofer for expert advice and assistance.
Inspecting and Assessing the Damage in a Fibreglass Roof
Before you begin repairing your fibreglass roof, it’s essential to conduct a thorough inspection and assessment of the damage. This will help you identify weak areas, cracks, and potential causes of further damage, such as plant growth or debris buildup. Pay close attention to the condition of the roofing membrane and look for signs of wear or deterioration. By conducting this initial assessment, you can determine the extent of the repairs required and develop a comprehensive repair plan.
During the inspection, take note of any areas that appear weakened or structurally compromised. These weak areas may require additional reinforcement or targeted repair methods to ensure the longevity and stability of your roof. Identifying these weak points early on can help prevent future issues and potential roof failures.
If you notice any cracks in the fibreglass surface, measure their length and width to assess their severity. This will assist you in determining the appropriate repair method needed to address each specific crack. Additionally, be on the lookout for any signs of water leaks or stains in your interior spaces, as these can indicate areas of damage on the roof’s exterior.
Inspect the roof for any signs of ponding or standing water, as this can be an indication of poor drainage and potential areas of weakness. Look for any clogged or damaged gutters and downspouts that may be contributing to these issues. Addressing proper drainage is vital to maintaining the integrity of your fibreglass roof and preventing future damage.
Tip: Regularly inspecting your fibreglass roof and addressing any damage promptly can help extend its lifespan and prevent costly repairs in the future.
Consider the surrounding environment and potential sources of damage, such as nearby trees or branches that may rub against the roof during periods of high winds. Trim back any overhanging branches to avoid potential damage to your fibreglass roof. Additionally, check for any debris or vegetation that may have accumulated on the roof, as this can trap moisture and contribute to further deterioration.
Signs to look for during the inspection:
- Cracks or fractures in the fibreglass surface
- Visible signs of wear or delamination
- Water stains or leaks in interior spaces
- Ponding or standing water on the roof
- Clogged or damaged gutters and downspouts
- Overhanging tree branches or vegetation
By thoroughly inspecting and assessing the damage in your fibreglass roof, you can gain a clear understanding of the repairs needed and plan accordingly. Remember to consult a professional if you encounter any significant damage or if you’re unsure of the appropriate repair methods.

Knowing When to Replace a Fibreglass Roof Instead of Repairing It
While repairing a fibreglass roof is often a cost-effective solution, there are instances where replacement is a better option.
If the existing roof is more than 20 years old, in poor condition with multiple areas of damage, or requires extensive repairs (exceeding 50% of the roof area), it may be more practical to consider replacing the roof.
Additionally, if the roof lacks adequate insulation or ventilation, replacement can improve energy efficiency.
Assessing the overall condition of the roof and weighing replacement costs against repair costs will help inform your decision.
“Sometimes, repair may no longer be feasible or cost-effective. By understanding the signs that indicate a need for replacement, you can make an informed choice that ensures the long-term integrity and performance of your fibreglass roof.” – Robert Johnson, Roofing Expert
Signs it may be time to replace your fibreglass roof:
- Extensive cracks or significant damage covering a large portion of the roof
- Multiple recurring leaks even after repair attempts
- Visible signs of sagging or structural issues
- Frequent repairs that are becoming increasingly costly
- Loss of insulation or poor energy efficiency
The cost of fibreglass roof replacement:
The cost of replacing a fibreglass roof can vary depending on factors such as the size of the roof, complexity of the installation, and choice of materials. On average, homeowners can expect to pay between £70 and £100 per square meter for a professional fibreglass roof replacement. It’s important to obtain quotes from reputable roofing contractors to get an accurate estimate for your specific project.
Common Defects in GRP Fibreglass Roofs and How to Fix Them
While fibreglass roofs are durable, they can develop a variety of defects over time. Common defects include cracking, delamination, and blistering. Regular inspections are essential to detect and repair these defects promptly.
Cracks and pinholes can usually be repaired with a resin topcoat. For larger defects, cutting out the affected area and applying a primer, fibreglass resin, and matting may be necessary.
Repairing Cracks and Pinholes
- Thoroughly clean the damaged area, removing any debris or loose material.
- Apply a resin topcoat to the cracked or pinholed area, ensuring it covers the entire damaged section.
- Allow the resin to dry completely before applying additional coats, if necessary.
Repairing Larger Defects
- Cut out the affected area using a saw or utility knife, ensuring the cut is clean and straight.
- Apply a primer to the exposed surface, allowing it to dry according to the manufacturer’s instructions.
- Apply a layer of fibreglass resin to the primer, followed by fibreglass matting.
- Ensure the fibreglass matting is fully saturated with resin and pressed firmly onto the roof surface.
- Repeat the process for additional layers, if necessary, until the repaired area is level with the surrounding roof surface.
Fixing Delamination
Delamination occurs when the layers of fibreglass separate, resulting in weak spots on the roof. To fix delamination:
- Scrape away the loose material using a scraper or putty knife, ensuring all delaminated areas are removed.
- Inspect the remaining fibreglass layers for any defects or damage. Repair any defects using the appropriate method.
- Apply a new layer of flow coat, ensuring it covers the delaminated area and blends seamlessly with the surrounding roof surface.
- Allow the flow coat to cure according to the manufacturer’s instructions before exposing the roof to any moisture.
Remember to follow detailed instructions and use appropriate repair products for each specific defect. Proper repairs will ensure the longevity and structural integrity of your fibreglass roof.
