They did just fine!
Nothing
Before the roof cleaning service, inform the customer to place ground covers wherever moss is not wanted or difficult to remove.
Nothing comes to mind.
Perhaps give an option on whether to charge credit card on record or other means, e.g. write a check.
Not a thing.
I was quoted a price for gutter cleaning and cleaning of my metal roof. What a rip off.
?
I thought there was a whitener used on the gutters, I could have misunderstood, but they are much cleaner. I am not sure how it could be done but there was quite a bit of debris from the roof on my backyard stamped concrete. Although it was washed off, the mess was blown into my rock which is a pain to get out. Not sure if there would be anyway around that,
You don't need any improvement you already do an excellent job. !
They are doing a great job for a great price.
suggestions
I really can't complain about any of the service you provide to me.
