What is this on Roof?

[Michael J. Merino]

This is device is on a roof, and the cable from the device runs to the controls for the watering sprinkler system. Is this some type of moisture monitoring device? The pin can be depressed and you can see where you can choose a depth.

The world's most simple, accurate, rugged, and reliable rain sensors. . costly–than an irrigation system that runs when it doesn't have to.in the rain. .　->

[Bobby G. Michael]

Yep, rain sensor.

Rain sensor lets that sprinklers know when not to run.

Those shingles do scream DIY.

[Paul Pendley]

Same here...looks like those shingles were a DIY job or billy bob contractor.

OK all you roofer wannabes.

If you're going to pontificate on the quality of roof installation, you should at least tell the poor guy what you think you see in stead of just patting each other on the back.

OK, I'll start, that way you'll know too.

Has to do with exposure - how much of the tab is showing. In this case the entire tab (and then some) is showing. The tabbed part makes up roughly half of the shingle.

You should never see the top part of the shingle.

Here's an article about installation. I didn't read the whole thing, but the pics are good to see what I mean.
