GRP Fibreglass Roofing
The Gold Standard in Flat Roofing
GRP (Glass Reinforced Polyester) fibreglass roofing is widely regarded as one of the best flat roofing systems available. At CraftShield Roofing, we are experienced installers of fibreglass roofing systems across Dublin, Meath, Laois & Kildare, delivering seamless, waterproof roofs that last for decades.
Unlike traditional felt roofing, GRP fibreglass creates a completely seamless surface with no joints or seams — meaning there are no weak points for water to penetrate. The result is an incredibly watertight, low-maintenance roof that can withstand Ireland's wet climate year after year.
Fibreglass roofs are also lightweight, extremely strong and resistant to UV damage and foot traffic — making them ideal for extensions, garages, porches, dormer roofs and commercial flat roofs.

What affects the price?
These are the main factors that influence the cost of a fibreglass (GRP) roofing installation.
Existing Roof Condition
If the existing roof deck has deteriorated or suffered water damage, repairs or replacement may be required before the new GRP system is installed.
Roof Design & Details
Rooflights, upstands, parapet walls, outlets, corners and pipe penetrations all require careful detailing to achieve a seamless, watertight finish.
Preparation Required
Removing old roofing materials, preparing the roof deck and ensuring a suitable surface for the GRP system are all factors that influence the overall project.
Project Scope
A small garage roof requires a different level of work than a large extension or commercial flat roof. The size and complexity of the project will affect the installation time.

FAQs
Fibreglass Roofing FAQs
How long does a GRP fibreglass roof last?
A properly installed GRP fibreglass roof can last 40 years or more. Our fibreglass roofs come with a 25-year material guarantee, and with minimal maintenance they often outlast traditional felt roofs significantly.
Is fibreglass roofing more expensive than felt?
GRP fibreglass roofing typically costs more upfront than traditional felt, but it offers far greater longevity and requires much less maintenance over time. When you factor in the 25-year guarantee and minimal upkeep, fibreglass is often the more cost-effective choice in the long run.
Can fibreglass roofing be installed in all weathers?
GRP fibreglass requires dry conditions for installation as the resin needs to cure properly. We schedule installations accordingly and can often work during cooler months. We'll always advise on the best timing for your specific project.
Can I walk on a fibreglass roof?
Yes, GRP fibreglass roofs are strong enough to walk on for maintenance purposes. However, we'd always recommend using proper access equipment and avoiding unnecessary foot traffic. We can also add non-slip walkway strips if required.
