Beginner Gardening: HELP! I'm about to lose my whole yard!, 1 by garden4moi

Last week we had new sod put down in our backyard. The day afterwards our lawn pest control company showed up to do their routine spraying and I told the guy we just had new sod put down the day before. We've been watering heavily with the sprinklers to help the sod. Problem? The excess water from the yard runs off towards the back wall where I have two trees (lemon and ficus) and a row of rose bushes. I noticed on Sunday that a few of the rose bushes had dark, almost burned looking leaves, then the leaves would just wilt totally and now it looks like the plant's almost dead. Yesterday I noticed the lemon tree (which is in front of the roses) has one side of the tree where the leaves turned yellow and curled and now looks very sparse and wilted. Ficus tree is looking quite wilted too but no discoloration that I can tell. I haven't sprayed these plants & trees with anything except the sprinklers. We've used this lawn service for months and this is the first problem I've had so I don't even know if that's the issue. It's the only thing I can think of because it affects multiple types of plants, all of which get runoff from the lawn. Area gets full sun (zone 9b, so it's hot).

Do you think this is caused by chemicals from the yard? Is there anything I can do to save them?

Thanks,
Kim
Here's a picture of what the rose leaves look like before they start to wilt.
