Our Smooth Installation Procedure
At Obsidian Roofing, we feel pride in delivering a flawless GRP fibreglass roofing installation from beginning to end.
Each project starts with comprehensive preparation – cleaning and drying the roof deck for a robust foundation. Once prepped, we apply a superior-quality primer to promote robust adhesion. Next, fibreglass matting is laid out uniformly across the surface before being coated with resin using rollers for a seamless, consistent finish.
The roof is then left to cure, enabling it to harden. A durable topcoat is employed for both protection and a tidy, finished appearance. Our specialists complete the procedure by examining the roof cautiously, addressing any necessary touch-ups, and ensuring that each bond and seal is secure.

FAQ’s​
How long does a fibreglass roof generally last?
At Obsidian Roofing, we install GRP fibreglass roofing designed for lasting effectiveness. These roofs are smooth, extremely water-resistant, and can manage severe weather and UV exposure. With adequate care, a fibreglass flat roof can last over 30 years, outlasting conventional bitumen systems, which typically last around 20 years.
Does a fibreglass roof require frequent upkeep?
Owing to its rigid surface and climate resistance, upkeep is minimal. Occasional cleaning to clear away leaves or moss will help keep your roof looking its finest. Our roof installers suggest an annual inspection, particularly if your system includes a warranty, to keep things in perfect condition.
Is installing a fibreglass roof a complicated procedure?
GRP fibreglass is a lightweight, cold-applied material, meaning there is no requirement for flames or torches. At Obsidian Roofing, our seasoned crew uses rollers and resin to craft a durable finish, decreasing installation time and cost while delivering a tidy, professional result each time.
Is fibreglass roofing more costly than other systems?
Even though the upfront cost may be slightly higher, the long-term value is where GRP fibreglass roofing really shines. With a longer service life and fewer repair requirements, you save more over time. At Obsidian Roofing, we provide detailed guidance and competitive costs to guarantee excellent value for your investment.
