Roof seal and drain cleaning.

[Jabberwocky]

How fastidious are you about keeping your roof seals and drains clean and clear? If you are not that good at keeping these areas clean and clear you should read page 72 in my T6 (Jun 19 build) California Supplement. I attach for interest.
Call me a cynic, and bear in mind I don't remember seeing this in my previous Cali's supplement (Feb 17 build), but this insertion could be used to try and wriggle out of certain warranty repairs if there is evidence of poor maintenance on the part of the owner.
