Conservatory roofs and rain: noise, leaks, timing and damp
Rain is the one thing every conservatory roof deals with daily. Our ledger of 100 English towns counts 1,014 wet hours a year in the average town, 65 noise nights and 26 hours of heavy rain. These pages cover what that rain does to the roof you have now, and how we plan a new one around it.

Two numbers to know first
A noise night is a night with an hour of moderate or heavier rain between 11pm and 7am: the average town gets 65. A dry working day has under 0.2 mm between 8am and 4pm: the average town gets 263, which is plenty to book a roof around.
