roof leaking 5 ft. below exhaust vent


Also note that the improperly nailed shingle was sliding, hence the slot below the nail.

roof leaking 5 ft. below exhaust vent


You lucky dog, you! I was writing a proposal this morning and spotted a roof I did 12 years ago with the same vent in it. It was probably black when I installed it. Obviously, my plan 'B' was the correct one to follow as I stated earlier.
No storm shield, no caulk, no leak. I didn't even caulk the nails which won't rust because I only used roofing nails, not those EG you see in Lowes, or elsewhere.

Spoken like a true contractor. "I don't follow those, they are for people who dont know what they're doing"...haha. Remember that abundant experience doing it the wrong way doesn't make it the right way. I've done lots of jobs where contractor's have to remove and replace things they've done because "I didn't read the plans, I just did it the way I always do it."

As I said, any flashing system should be installed to not need caulking. Caulk should and always be a secondary measure. If it leaks without caulk, it will leak with caulk. If it doesn't leak without caulk it shouldn't leak with caulk. I've never known caulk to create problems when it was installed as a secondary measure unless, of course, it was installed poorly as shown in tinner's pic....

There could also be another explanation. Those vents are made of cheap metal with a single hem, and maybe tack-welds. When I looked at the one I installed, I realized there are two other things I do as normal as breathing and would never remember to comment on.
1st.- At the hemmed joints, I apply a gutter sealer on those joints inside AND outside hours before the install. 9Backup plan #1)
2nd. No matter what color it already is, I then paint it to match again because the coating they come with will allow them to rust through within a few years. Many never make it for the shingles' lifetime. My records show that I painted the one I installed silver.

These are things I do as second nature and never list them on my proposals. They are so necessary and so redundant that 'it goes without mention' so to speak that I will do them.

Thank You.

If done correctly, you won't need a second measure.

Some people are just not cut out to do roofing, but they still do it anyways. Those types usually aren't in business for 30+ years either.

Well, lots and lots of rain, no leaks. I'll keep an eye on it. Not sure if I should rip it all up and re do it or not.
