Exposed nails in headwall flashing

Hi. I am not sure if this is the right place for this question. If so, my apologies. I am taking the roof inspection training course, and am on the essay portion of the course. I was looking for clarification on a possible defect condition. I observed headwall flashing where the lower portion of the flashing is nailed down into the asphalt shingles below, leaving exposed nail heads in the flashing. Is this a defect? Thank you very much.

At a minimum, I would recommend the nail heads be sealed. But after a while that will become a maintenance item. I would be more concerned about the use of shingles on what appears to be a relatively flat or very low slope roof.

Thank you, Richard! Yes indeed, it is a very low slope. Tomorrow I will calculate the slope. I appreciate your feedback!

That’s nice that they are angled, to ensure they collect the most water possible. :+1:

That is the largest residential headwall flashing I have seen. And, the siding does not not come down very far, makes me curious about how far up under the 1st course of siding it goes.

These angled fasteners are an issue in my book, especially with no sealant.

It could be tucked under the 2nd course. Anything is possible Brian.

@tlong11 Yes those exposed fasteners are an issue and should be called out. They may not be leaking today, but in time they will. Recommend they be sealed, using a proper sealant for the application.

I’m leaning towards that. In fact, I think it is a repair over old existing, but that’s just a hunch.

1st course was probably junk so it just got covered to hide it…:roll_eyes:

If they were sealed with a neoprene washer under them, I generally will not call them out if they sit flat. As others have stated, those are not sealed and the angle is just lazy work from install.

Most likely shot in with a nail gun by the looks?

100% agree with that consistency. If hand banged in, they would be at all angles and would maybe have washers used…Just laziness.
