GRP roofing is gaining traction among homeowners and business owners alike. But what is it, and why is it becoming so popular? This guide will delve deep into GRP roofing, helping both our existing and prospective customers understand its intricacies.
What is GRP Roofing?
GRP stands for Glass Reinforced Polyester. It’s a composite material made of polyester resin reinforced with fine strands of glass. GRP roofing is not only strong but also watertight, making it a favourite for flat roofs and other applications.
Performance Characteristics of GRP Roofing
- Durable: One of the most significant advantages of GRP roofing is its durability. It resists common wear and tear and can withstand varying weather conditions.
- Watertight: GRP roofs provide a seamless finish, which means no leaks. This seamless nature ensures a waterproof surface that keeps your interior dry.
- UV Resistant: GRP roofing also offers protection against harmful UV rays. This feature not only safeguards the roof’s integrity but also ensures a longer lifespan.
Like any other roofing system, GRP roofing can also face some issues:
- Cracks: Over time, small cracks can appear, especially if the roof experiences heavy foot traffic.
- Delamination: This refers to the separation of the GRP layers, which can lead to leaks.
- Pinholes: Tiny holes might develop during the curing process or due to wear over time.
Life Expectancy and Insurance Implications
GRP Roofing is known for its longevity. With proper care and maintenance, a GRP roof can last upwards of 20-30 years. Moreover, thanks to its robust and watertight nature, many insurance companies view GRP roofing favourably. This positive outlook can translate to lower premiums for properties with GRP roofs.
Regular Inspection and Maintenance
For optimal performance, regular checks are crucial:
- Bi-annual Inspection: Hire a roofer to inspect the roof at least twice a year. This way, any potential issues can be caught early on.
- Clear Debris: Ensure the roof is free from debris like leaves, which can trap moisture.
- Check for Damage: Especially after extreme weather events, inspect for cracks or any signs of damage.
- Re-coating: Over time, the top layer might wear out. Consider re-coating to maintain the roof’s integrity.
Installation Process and Systems
The installation of a GRP roof involves several steps:
- Decking: A good, solid base, typically made of OSB3 boards, is laid.
- Edge Trims: These are fixed in place to guide water runoff.
- Applying the Resin: The resin, infused with the glass fibre mat, is applied.
- Top coating: Once cured, a topcoat is applied, which gives the roof its waterproof and finished look.
Various systems available on the market cater to different needs and budgets. Some popular choices include Cure It, Topseal, and Scott Bader. When selecting a system, consider factors like warranty, finish, and overall cost.
GRP roofing stands out for its resilience, longevity, and ease of maintenance. By understanding its features and ensuring regular upkeep, you can benefit from a roofing system that has served you well for decades. Whether you’re considering a new roofing solution or looking to maintain your existing GRP roof, this guide aims to steer you in the right direction.
