One Dry Day

Conservatory roof replacement in Weymouth

Across 2024 and 2025 the Met Office 2 km model puts 1,160 mm a year on Weymouth, which makes it the 21st wettest of the 100 towns we counted. On 265 days a year the hours from 8am to 4pm stay dry, so finding a fitting day is a question of watching the forecast, not waiting for summer.

At night it is a different story: 72 nights a year bring an hour of moderate or heavier rain, 27th highest of 100. We replace polycarbonate and glass conservatory roofs in Weymouth with 75 mm insulated panel roofs from £3,000, fitted onto the frame you have.

When to book in Weymouth

August, June and July gave Weymouth the best odds of a dry working day; September gave the worst, at 58%.

The longest run of dry working days in a row was 38, ending in July 2025. The longest wait without one was 7 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 Weymouth

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. Weymouth had 72 a year, more than the 65 of the average town, and 11 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 Weymouth

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

Our ledger counts 265 dry working days a year in Weymouth, 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 Weymouth than elsewhere?

The roof is the same anywhere; the rain is not. Weymouth has 72 noise nights a year against 65 in the average town we track, and 39 hours of heavy rain.

What does a new conservatory roof cost in Weymouth?

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.
