Conservatory roof replacement in Calne
Calne had 941 mm of rain a year across 2024 and 2025, about the same as the 911 mm the average town in our ledger had. That still leaves 259 days a year with under 0.2 mm between 8am and 4pm, the kind of day a roof comes off and goes back on.
It also counts 63 noise nights a year, nights with rain hard enough to drum on polycarbonate between 11pm and 7am. We replace polycarbonate and glass conservatory roofs in Calne with 75 mm insulated panel roofs from £3,000, fitted onto the frame you have.

When to book in Calne
In Calne the driest working months were March, August and November, and the wettest was February, when 58% of days stayed dry from 8am to 4pm.
The longest run of dry working days in a row was 34, ending in April 2025. The longest wait without one was 6 days. That is why we book roofs a week or two ahead and confirm the day on the forecast: a dry day turns up in almost every week of the year. When to book a roof swap has the full reasoning.
