Why Southport Flat Roofs Need GRP Fibreglass
Traditional felt and torch-on flat roofs rely on joints, and joints are exactly where coastal rain, salt air and wind-lift start their work. A GRP (Glass Reinforced Plastic) fibreglass roof is laid as one continuous, seamless membrane across the whole deck: no joints, no seams, no weak points.
We have installed advanced flat roofing systems across Southport for over 45 years, from garage and extension roofs to full commercial decks, and we build every roof to shrug off the worst the Irish Sea sends our way.
