I know how it goes. And they probably expect you to do it the next day, as if you've been keeping your schedule open just for them.

We did two jobs this week, and have one tomorrow, it's December 1st and we are still getting calls and hits, when you live in the mid west with all the wacky weather this summer, getting all in we can. This time of the year is great, we can mess the mulch up, leafs are down. I hope that it stays like this all winter, high 40's, mid 50's, frost is on the roofs, we just rinse it off, let it drain down and let it bake a little, then spay. Might try a pre-heat with some hot water, maybe about 100 degrees to see if that loosen up the shingles. Added some IPA today, hard to tell if it made a difference.
