One Dry Day

Conservatory roof replacement in Tonbridge

Tonbridge had 701 mm of rain a year across 2024 and 2025, less than the 911 mm the average town in our ledger had. That still leaves 269 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 62 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 Tonbridge with 75 mm insulated panel roofs from £3,000, fitted onto the frame you have.

When to book in Tonbridge

In Tonbridge the driest working months were June, August and April, and the wettest was September, when 62% of days stayed dry from 8am to 4pm.

The longest run of dry working days in a row was 24, ending in March 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.

Rain at night in Tonbridge

We count a noise night whenever an hour between 11pm and 7am brings 0.5 mm of rain or more, the Met Office's moderate band. Tonbridge had 62 a year, about the same as the 65 of the average town, and 4 nights with a heavy hour over 4 mm.

In the lab, heavy rain on 25 mm polycarbonate measures 64.6 dB against 52.0 dB for double glazed roof glass. Nobody has published the same test for aluminium panel roofs, so we will not put a number on ours. How loud rain is on each kind of roof sets out what is measured.
