No mail delivery, or anything else human for that matter.
Daughter, husband, dog and small child were in a park for a family photo shoot not long ago. Lovely photos until the end when dog found something yummy behind a stone wall. Last few photos show Mom, Dad and baby sitting on the wall. Mom and Dad have rather strange expressions. Dog is no longer part of family group.
You should have taken pictures! Blow them up to 2’ by 3’ and sneak over to their shop. and paste them on the sides of their van! 
Thankfully, I haven’t had that exact problem, but I have a wooded side lot that, while my property, looks wild and abandoned. The only unnatural thing we do with that bit of ground is kill any poison ivy. (Yes, I use Round Up. I have a twenty five year old one gallon bottle of the stuff and it still kills with one application.)
For years I’ve had to pick up discarded garbage along the roadside there. People just thought it was free dumping ground. Two weeks ago I spent $1,600 having a Belgium block border placed at the road’s edge to inform workers who throw their lunchtime trash, high school kids who throw their empty beer cans and bottles, and neighbors with grass bags the town won’t pick up, that someone owns the property.
A minor negative consequence is that from now on, water rushing down hill on the road will no longer be partially absorbed by my property and will continue on down the hill doing a bit more damage than previously to the road. So be it.
I took photos. Public shaming is plan B. Plan A is to get them to come clean up their shit. I’m waiting for my neighbor to return for him to deal with the roofers or to give me their name and contact info. If they prevaricate, then I will be advertising their services.
I’m just wondering, what self help remedy does a homeowner have when he catches someone taking a dump in his yard?
Never mind answering for Florida, I realize you can probably claim fear of turds and shoot the pooper and his turd there.
Sounds like you’ve already backed them into a corner. For best results, post them on your Facebook page! :eek : 
Post them on THEIR Facebook page
It’s easier to wash a dog than teach it to gargle.
Hey, THERE you go!
I don’t wish to rain on your parade but unless you can prove who did it, the roofing company could successfully sue you for libel. just sayin’
I don’t want to stop, or encourage, you but maybe you should talk to a lawyer before beginning your plan B public shaming campaign.
On top of the legal aspects of blaming the roofers with just opportunity and implied motive as evidence, it’s not the worst offense in the world.
I don’t think that we should encourage everyone to poop outside or pooper scooper laws should be abolished, but everything that isn’t human or a house pet is out there pooping every day. Get a garden hose and a plastic bag and move on.
Of course, do this after you’ve mentioned to your neighbor that he might like to get a port-a-san the next time he has construction done*, and offered him the use of your hose and plastic bag. He’s the one who brought in contractors on the cheap, and didn’t supply facilities.
*I have one in my front yard right now. It’s originally there for the roofers, who didn’t need to be in the house. It’s still there because I’m not always there for the remodel. I love the thing, and wish I could somehow keep it there after there’s no building permit. Who wants to go all the way inside to use the bathroom?
Let the lawyer see the photos–they should be incriminating enough.
Denial of squatters rights
slow clap
First, the OP is a lawyer. Second, he doesn’t have to prove who did it. He has to prove his belief the roofer did it is reasonable. Third, no.
