Stainless steel chimney crown cover

[Chimchimery]

Below is the chase! Arrived in a pallet and was held upright. It is pictured now in my entrance way as it takes a lot of room.

Even at 22 gauge there is pretzel flex with it. Two things I noticed after getting it unwrapped. Lots of scratches on the top. A few more than just surface scratches. Second thing was the short ends where the drip edge runs -- maybe that is the way it is designed -- but the drip edge looks almost bent (IE. bottom left in the picture and top right on the other side).

Don't know if either the scratches or the 'bent' end is normal. The long ends don't have the bent. Yes, the price was high; but mine was customized to fit my chimney because it is not square. I didn't want to contend with too much gap on one side. That alone added $150, plus the extra gauge.

I have to get prepared next buying the tapcon screws, create pvc spacers if needed, pre-drill the holes perhaps in the chase. Don't figure it will be picnic. Have to get it up there as well as use my clamps to hold it at just the right height.

And we are in the 100's temperature these last few days. So going to wait until we are back in the low 90's.!

Trying to again visualize the mounting procedure I need to follow before carrying the chase to the roof.

I understand I can purchase stainless steel tapcons and could use stainless steel washers.

My chief concerns are:

1) How long of tapcons should I purchase and the diameter. Intend to go into the brick.

2) If I pre-drill any or all holes in the chase, which diameter should they be?

3) How to I make sure my holes line up with the holes I have to drill for the tapcons? I understand there is not any room for play with tapcon screws going into brick. The alignment is a big concern of mine.

4) Spacers - I assume I should have an array of different lengths? Possible the PVC pipe could be cut to length on-site on the roof.

I plan on purchasing a HF Brauer Hammer drill and I already the an impact driver.

Son-in-law might offer his services around Father's Day, so I want everything ready to go if he volunteers.
