Skylight - leak - fixed - but questions remain

House built in 1984, two Anderson skylights.roof windows (operable). In 2007 we had the roof redone, opted not to replace the skylights. 10/12 pitch roof.

A leak in one developed this past year, so we had a contractor out to check it / reflash it. He told us the head flashing was never tucked under the shingles. I called the roofing company and the owner told me "since it didn't leak in 15 years, they don't see how they could have installed it incorrectly". They want $200 to come out and inspect, and $400 to reflash the top.

Now - could there be a leak we just don't see? My question is - who do I believe? I can't find an installation manual for these windows, they are out of production (since 2009). That top piece of flashing that doesn't tuck under the roof looks suspicious, but perhaps that was the design?

How do you know you have a leak if you don't see it? If you have a leak it doesn't matter. It needs to be fixed.

Either the contractor or roofing company should be able to do the repair. It probably will need to be re-flashed. The flashing on top of the shingles at the top of the skylight in your photo isn't doing anything except collecting leaves.

Not sure if this is what you have.

I don't know what that extra flashing on top is, but its not a factory head flashing. The head flashing is part of the piece that wraps around the top of the skylight and its under the wrong row of shingles. Should be under the next row down. Unknown why any other flashing was added. Maybe to try to fix their mistake.

Was the former roof also asphalt shingles, or something else?

@johnam - unfortunately that's not the same window - the guide is for 1999 to present... our windows were installed in 1984.

@XSleeper - the former roof was asphalt. The color of that extra flashing on top is the same as the aluminum flashing used around the skylight - and I doubt the roofing company put it on there - that is it was either factory or done by the original builder. When the weather gets nicer I'm going to get up on the roof and inspect it myself, probably will end up doing the repair on the second skylight myself.

I couldn't justify paying the first contractor who came over any more to do the second window - I think he overcharged me as the quote was to redo all the flashing, but he only needed to do the top flashing of the skylight. I am not opposed to paying someone to do this - but at a certain point when you (feel like you) get screwed over you lose any faith you have in contractors, no matter how nice they are.

Also - technically it's a "Roof window" that opens (not stationary):

Here's the real odd thing - when talking with the Andersen company - the date code on the glass told them it was manufactured in... 1996. House was built in 1984 and the windows have never been changed/repaired. I'm guessing either the code was etched incorrectly or their database is wrong.

I found a thread on a different forum that claims Andersen bought out Roto: https://www.contractortalk.com/threa...anyone.151347/

OK - so I did a bit more googling:

https://www.andersenwindows.com/~/me...ionaryroof.pdf

Looking at the diagrams (page 5, 7) the piece of aluminum might be a "Water Deflector"? That's for a modern version of their skylight, however.

Page 23/25/28/29 show diagrams that correspond to the skylight we have. No mention of a "Water Deflector".
