Polycarbonate roof?
We moved into our bungalow in 2004 which has a Sun room. Two of the sheets have water droplets between the sheet walling I've been told they have come to their sell by date and will need replacing at cost of £200, am I being conned? It's a flat or pent not a fancy profiled one with each section about 2.2mt in legth
