Flat Roofing in Romsey
Flat-roofed rear extensions are common across Romsey's Victorian terrace stock — single-storey kitchen extensions added throughout the 20th century, many with felt that has been patched repeatedly. The town's position in the Test Valley means persistent ground moisture and humidity, which accelerates felt deterioration faster than in drier inland towns. GRP and EPDM are both fully resistant to these conditions.
GRP Fibreglass in Romsey
GRP is our primary recommendation for most Romsey residential flat roofs. The seamless installation and fully waterproof membrane perform well in the damp Test Valley conditions. No maintenance required for 25-plus years.
EPDM for Larger Extensions in Romsey
For extensions over 30 square metres, EPDM single-ply rubber is our preferred system. It handles the temperature variation and persistent moisture that Romsey roofs experience across the seasons.
