When choosing the right flat roofing material for your property, consider a few options. Some of the most popular choices available are GRP fibreglass roofing and felt roofing. Both materials have their advantages and disadvantages. Now, the question is which one stands out as the better choice for homeowners in 2026? GRP fibreglass roofing in Hertfordshire has gained significant attention for its durability and long lifespan. However, the felt roofing still has its place for some.
Key factors that differentiate GRP and felt roofing
Durability and lifespan
One of the most significant factors in choosing between GRP and felt roofing is their lifespan and durability.
GRP fibreglass roofing is known for its exceptional durability. GRP roofing can last up to 30 years with proper maintenance. Its fibreglass structure is highly resistant to cracks, weathering, and wear. GRP roofs are ideal for homeowners who want a long-term roofing solution.
On the other hand, felt roofing is a functional option. However, it may have a shorter lifespan. It usually ranges between 10 and 15 years. It’s more susceptible to weather-related damage, including temperature fluctuations and UV exposure. Therefore, the material cracks or degrades over time.
Waterproofing and leak resistance
Waterproofing is a critical factor for flat roofs, and the two materials perform differently in this regard.
GRP is a seamless roofing system, which means it doesn’t have joints or seams where water can seep through. Therefore, it is highly waterproof and leak-resistant. Once installed, it provides a strong, continuous barrier against the elements.
Felt roofing has seams and overlaps, which can be vulnerable to water penetration. It is especially true if the felt begins to crack or degrade. While felt roofs are initially waterproof, they require more attention over time to maintain this seal.
Maintenance requirements
The level of maintenance required for each roofing material can significantly impact long-term costs.
Once installed, GRP roofing requires very little maintenance. The surface is smooth and resistant to moss, algae, and dirt buildup. It is also less prone to wear and tear, meaning fewer repairs are needed throughout its lifespan.
Felt roofing typically requires more frequent maintenance. Cracks, splits, and blistering can occur, particularly in areas with extreme weather conditions. Regular inspections and repairs are needed to ensure the roof continues to protect the property effectively.
Installation Costs
Cost is always a key consideration when choosing a roofing solution. Installation costs can vary widely between GRP and felt roofing.
In the case of GRP, the initial installation cost tends to be higher than that of felt roofing. However, given its longevity and minimal maintenance requirements, it can be more cost-effective in the long run.
Felt roofing is generally less expensive to install, making it a more affordable option for those on a tight budget. However, it may cost more over time due to frequent repairs and eventual replacement.
Ultimately, the choice between GRP and felt roofing comes down to your budget, long-term goals, and the weather conditions.
