New Member here, I have a concern about new Chimney flashing


Where's an average "DIY"er, going to get there hands on 20 oz. lead-coated,
copper?!?
Who's going to "form" it to fit?!?
The bricklayers?!?
Sure they will - they all have "Malco" tools!

We ain't here to tell anybody how to do anything - perfect! -
We're here to try and help with problems!

I know, I know. Im just saying what the best materials are, and the best way to do it. 16 oz. Copper is fine, so is cutting in with a right angle grinder about an inch and a half and lead wedge and sealing your counter flashing. You are of course correct. Its hard to get masons to set flashing properly even on commercial projects let alone residential work.

Aluminum can be and is often used, it just isn't the best IMHO due to its lack of malleability, and the effect mortal has on it. Propely set copper or LCC (Prefered) Counter flashing will last the life of the chimney, and many roofs.

Any decent roofing supply will have 16 oz copper, and 3 lb. lead. and it can be broken with a couple of sharp cornered boards like oak, and some C clamps. Its soft, and malleable. For wedges, you just cut off 1 inch strips of sheet lead and roll it. You need duck billed tongs for any metal work, IMO, and right and left snips. Thats a given.

I've got a "brake".
However, I admit that I've had to use the boards and C-clamps -
in a pinch!

Update,
Had a meeting with the roofing company today at the house. They looked over the pictures and info you guys shared and checked the attic. They cant get up to the chimney right now as it is too frosty to climb on the roof. He saw the daylight around the chimney and said it might be clear cauling?? We told him we werent pleased and I said we were advised it was the wrong type of flashing he said if we wanted to go with someone else we could...! He is going to check this afternoon to see if theres anything obvious leaking caulking missed etc. He said it is guaranteed for 10 years I laighed and said it hasnt lasted 3 months! Will see what he finds this afternoon..

It is absolutely amazing to me that this guy apparently does this for a living but he does not care to learn the correct way to do it, and tells you to get somebody else, so he can move on to the next unsuspecting victim.

ABSOLUTELY AMAZING!

Of all the trades, roofing requires no apprenticeship, or formal education to become a "roofer". This may be why 87% of construction litigation involves the roof.

I forgot to mention that there is step flashing underneath that large black cover flashing. You can see the step flashing between the deckboards and chimney in the attic.

Step flashing, or base tins do not go at the deck level, they go between courses of shingles, and redirect water out onto the surface of the roof.

And there would be no way to see light through step flashing.

We can't see any daylight through the step flashing only where the flashing meets the chimney itself. Roofer came back and checked the flashing once the frost was gone from the roof for safety and resealed all the flashing.. We went up in the attic with him and he can still see daylight where the flashing meets the chimney.. funny enough we told thm this mornign we werent happy and wanted it removed and redone and once he tried and fialed to seal it he said HE wasnt happy and it is all coming off tomorrow and being redone correctly... wanted to say told you so but thought better of it......

Reflected daylight can sometimes be seen when looking up the bricks while inside the attic. Direct light isn't good.
And that chimney needs to be flashed. It looks like a kindergartener did it, not a roofer.

Some of the inner details of the chimney flashing. I don't have many 'finished' pix because it's what's underneath that matters for 99% of the project. The counterflashing accounts for the other 1%. These are pix of chimneys without crickets. http://www.albertsroofing.com/Chimney%20Repair.htm

God it irks me anytime I hear someone mention caulk in any situation like this. Caulk has nothing to do with a properly flashed chimney. Caulk should only be considered a secondary seal to anything.

Boy are you correct OldNBroken. You cant believe how many projects I have been on where a client had a small leak, then sent bubba up on the roof with a caulk gun and a case of sealant, and then it rained inside. Caulk in weep holes, caulk in the drain holes in storefront window systems, you name it they seal it. Then you have the morons that clear seal brick in cavity wall construction. You go back in the spring and the wall looks like it had acne, the face of the brick is blown out from frost all over the place. Oh well, I should not complain, they make work for me.
