Hey look, another leak thread

Had some storms today with wind blowing the rain a bit. This caused a drip in the garage. Cut a hole in the ceiling and found part of the wate . Very little, but enough to wet out some insulation and drip onto drywal. Made its exit through a nail hole in the drywall.

I'm pretty sure it's coming from where some coax cables enter the room above. The wood around that hole is wet. Love people that drill through the side and shove it throug . The wide part thats supposed to help seal it came off pretty easy and somebody shoved a bunch of clear silicone in the hole.

It is potentially coming from a raised shingle in the same spot.

Pics attached.

I'm trying to buy some time before we redo parts of the siding and paint the whole place. we don't use that cable as it runs from a satellite we don't use either.

I'm thinking cut the coax, clean out the hole, dap sealant to fill the hole, prime and pain . Reseal around the window above it, prime and paint the trim which is wet. Also the vent further up is loose so reattach that properly. Use some roof sealant to seal where they ran screw into the shingle and to tack the lifted shingle down.

Good plan? Bad plan?

Stopping the leak is always a good plan. Yes, if the cable is no longer used, get rid of it. Nice they cut right into the wall flashing. Brilliant.

One question, can you tell if there is one or two layers of shingles on the roof? Look along the gable end, you get a good side view there. I see no reason why- if there is only one layer- why those shingles would be sticking up like they are. That's what you typically see when people roof over with a 2nd layer. And roof overs are notorious for leaking at the wall. (Around the corner to the left, not pictured.)

Unrelated, but it also looks like your shingles dont overhang the drip edge much, if at all.

I certainly am no roofer so here is a pic. I expected I would see 2 complete roofs if it was reroofsd. To my eye, that's not what I saw. If there was a reroof then it looks like they pushed a new shingle under and the old one. Perhaps that is how they do i . House is 18 years old so I would be surprised. Then again nothing surprises me. Wasn't noted in home inspection last year either. The sellers disclosure stated it was original.

As far as overhang over the drip edge. It could be an illusion from how they did the gutters.

That looks like a single layer. There goes that theory.

Thanks for confirming. I need to push on that shingle area to make sure it is not soft and swollen causing that issue.

In the meantime, I see some cleaning, filling, caulking, sealing and painting in my future. Not what I really want to do, but it beats the alternative.

Got up there today. Cut the wires and pushed them back through. Trying to decide best way to patch the hole. Use exterior siding sealant after giving the wood a week to dry?

Just use roof patch in the hole? Does that cause future issues?

Also see they stapled the last row of shingles through the top. Seems odd to me. Wondering if I should coat the tops of those with some sealant since I'll be up there.
