When to book in Dover

Book in June and about 85% of days are dry through the working hours in Dover. Even February, the weakest month, manages 51%.

The longest run of dry working days in a row was 27, ending in May 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 Dover

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. Dover had 70 a year, more than the 65 of the average town, and 10 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.

Questions from Dover

How many dry days does Dover get for fitting a roof?

Our ledger counts 258 dry working days a year in Dover, days with under 0.2 mm of rain between 8am and 4pm. Most roofs need one; we pick it from the forecast in the week before.

Is a polycarbonate roof noisier in Dover than elsewhere?

The roof is the same anywhere; the rain is not. Dover has 70 noise nights a year against 65 in the average town we track, and 32 hours of heavy rain.

What does a new conservatory roof cost in Dover?

Guide prices are the same as everywhere we work: from £3,000 for a small roof, £4,000 for medium and £5,000 for large, fixed in writing after a free survey.

Do you keep my conservatory frame?

Usually, yes. The bars, the dwarf wall and the frame get tested at the survey, and only a sound frame gets a panel roof price.
