Mike,
Those could be zinc strips that help deter algae build-up on the shingles. Algae/moss likes to grow on the north and west sides of the roof, since that is where it gets less sunlight.
Only one problem, if these are zinc strips, they are suppose to be installed under the ridge shingles and extended throughout the entire ridge line.

Could be zinc strips but I don’t think so…we don’t have much of an algae problem on roofs here in central Texas. Some, mind you, but not much so I doubt that’s what it is, but it could be. Also, these are way out in the middle of the roof field not anywhere near the ridge. I’m going to wait a week or so and call my client back to see if he took my advice to contact a roofer and then maybe I can learn for sure what they are and I’ll let you know.

I just decided to look at the pics one more time and in pic #1, I can see a gouge on the face of the shingle over this sheetmetal. I now think that this added material is preventing a leak from occuring.

David, I agree, I saw the gouge as well. Only thing is, this is a 4 year old $300k house. Why would anyone patch or allow a patch like that to be made? Why wouldn’t a roofer or even Joe-Homeowner use another similar shingle if it was to address the ding? Just doesn’t make sense to me.

I saw a strange shingle patter on top of said sheet metal. looks like something else is going on (or was). roofers smoke some strange stuff being so close to god and stuff.(kidding, I was a roofer once.)

Hi Mike,
Ran into a similar case this past week. About half a dozen or so pieces of flashing material slid underneath the shingles of a 1800 Sq. Ft., one story. Roof had hail damage that was never repaired also. The pieces I found were near a full mortar chimney that was pulling away from house. Not next to the chimney but within 10 feet of it. Flashing around the chimney was in disrepair.
These were strips of flashing material being used. No damage around shingles but shingles appeared either misaligned or improperly installed. I expect they were experiencing water penetration and tried to fix it. Inside of house freshly painted and no other specific water signs connected to possible roof issue.

It’s just metal flashing to stop leaks and it is a lazy fix.It’s much easier to stick a peice of flashing under a shingle than it is to replace the damaged shingle.Although if one waits for cooler weather, about 60 degrees,the fix is really not that hard. I say 60 degrees because thats when it’s easier to separate the shingle from it’s tar strip without tearing the shingle yet the shingle is still plyable enough to bend so one can nail the course below it without breaking the shingle above it.
