When to book in Kendal

Book in March and about 76% of days are dry through the working hours in Kendal. Even September, the weakest month, manages 52%.

The longest run of dry working days in a row was 28, ending in May 2025. The longest wait without one was 11 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 Kendal

A noise night is one with at least an hour of moderate rain (0.5 mm or more) between 11pm and 7am. Kendal had 92 a year, more than the 65 of the average town, and 18 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.
