GRP ROOFING RANGE
GRP (Glass Reinforced Polyester) roofing is a popular roofing solution that offers exceptional durability, weather resistance, and longevity. Made from a combination of polyester resin and chopped strand mat glass fibers, GRP roofing systems are lightweight, seamless, and easy to install. They're also highly flexible, making them an ideal choice for roofs with unusual shapes or contours
