Chimney flashing

Does anyone see anything wrong with this chimney flashing? The roofer didn’t seem to…

the flashing is fine the roof is just going the wrong way…

LOL. That about sums it up :wink:


Maybe it looks better this way.


Still not a good picture. But it appears that the flashing is on top of the shingles instead of the other way around. The upper shingles should overlap the flashing.

This one from Inachi is better. :slight_smile:

…be familiar with good roofing practices?

Not to difficult to figure flashing should be below tile upsteam.
Lack of step flashing is more common than not, as step flashing takes work.
In Chicago a wrap around is the standard.(yes wrong but common)

I’m not even surprised to see how many roofers that simply do not have logical knowledge in “GRAVITY”. The percentage is pretty high.

That’s why so many fall off roofs.

Man I have bent many chimney flashing ,and I also use counter flashing.
Takes 20 minutes on a job like that.
This should have been started from the bottom ‘‘lowest part of the chimney and then 2 sides and end full strip on top.’’
It is sealed or bonded with a wrist lock bend. Very simple.
I have not seen 1 roofer doing shingles roofs, able to do a wrist lock for over 20 years.
The tin work is the weakest link in the chain on roofs.
As for step flashing, its the best but takes time and you have to cut into the brick masonry and roofers are roofers and tinsmiths usually apply wrap or step flashing.
With a gum edge on the wrap flashing to hold a liberal amount of good caulking its is the best’’ fast method’’ for flashing and I have seen it last over 15 years.
Its a dying art . Step flashing and tin-smiths in general.

Remember we want to educate on this thread. So what should have been done first?

  1. Head flashing needs to be under the shingles.
    2 Cut a slot into the brick ready for the counter flashing.


There is a solution to this problem. I found it in one of the attics I inspected. When it leaks, you collect the water.

Of course, there is some criteria for doing it this way:

1)You have to add additional bracing so the 800 lbs won’t fall through and kill someone.

  1. You build the container large enough that it won’t overflow during a long rain.

  2. You build the container large enough that it can hold the water and evaporate between rains

  3. And last, you have to build a funnel of sorts to direct the leak into the container.

  4. Oh, I forgot, you have to patch the ceiling where you brought this container up as it is too large for the access opening.

But when you are done, you can sit back and admire your feat of engineering, maybe even show it off to you visitors to impress them! :mrgreen:

That’s a good one Mark. :slight_smile:

Would not it have been a good idea to install a cricket due to the potential to collect debris and snow.

With the humor of my previous post aside (the photo is real - about 4 years ago), my practice when encountering these issues is just as has been used in this post by previous members, 1) photo the issue, 2) report the defect & 3) give the client a photo from the NACHI library or Code library of how it should be, and 4) Recommend repair by a professional. I try to not only point out what is wrong, but give the client clear direction when standards are so easily available.
