I made use of the mid 50's and no rain today, and got my flashing installed. I went under an extra row or two of shingles, and covered about 3/4 of the flashing. I used Through the roof sealer on the bottom of the flashing, running the whole perimeter including the bottom edge (in a V shape on the bottom edge, and left about a 1" gap open to drain any water. Hopefully this will also minimize wind blowing rain up under that edge?)
I also used it on the screw heads, to reseal the shingles to each other, and to seal the shingles to the flashing. I cut a 1" gap between the flashing and the edge of the shingles so nothing gets dammed/caught and stuck.

Should I have used more screws on the edge of the flashing? I figured the less holes i poke the better. I only have the bottom row, and 1 up each side. I don't see how it could go anywhere or leak since its sealed well, but wanted to double check.

The storm collar isn't on in this picture, but it's installed with silicone sealer. I also have two more 36" chimney sections to add, but i'm waiting on my chimney support kit to get here.

Thanks, Will

No more screws are needed, but this looks like the flat roof flashing (6DP-FF) and not the one for the slope of the roof. DuraPlus 6DP-F6 flashing is for a pitch up to 6/12.

The kit said the it's the adjustable flashing for 0/12-6/12. Besides that I don't know. I didn't think to check the sticker on the flashing and double check it was the correct part number. Crap.
 
Was the kit - 6DP-KMFG? They show a sloped roof flashing in the catalog for that kit.

The kit is 6dp-ktup
It shows a sloped roof flashing on the package for that kit. Not that this helps. I found a picture of the contents on eBay and it looks like a flat to 6/12 flashing is what is in the box. What is the roof pitch?

You say you are adding 6 more feet of pipe. That much pipe above the roofline requires those roof brace stilt things. More roofing.

There's no doubt in my mind you can make that work.

you may need a custom storm collar or something, but no need at all to tear that all apart, imo.
 
It is a 6/12 roof
That's what it looked like. It's at the limit for the flashing, but it will be ok. As Highbeam noted, an extended roof bracket is required for the chimney pipe at 5 ft above the roof penetration. DuraPlus part 6DP-XRB

Yep it’s been ordered a couple days ago 👍

Nice clean install. They don't give much of a flange on the roof portion. Some ice & water shield would be a good second barrier of defense, but if it don't leak, that's all that counts. Good job
