Hey All,

So I'm installing a Duratech chimney for my new stove, and wondering if anyone can guide me on flashing choice. The two options are the low-slope, which accommodates anything from flat (0/12) to 6/12 pitch. The steep slope one accommodates 7/12 to 12/12. My roof, however, is exactly 6.5/12. I called Duravent, but they were no help. The rep seemed to not understand that the numbers represent real life measurements.

As always, thank you in advance.
 
That's not a bad idea, thank you moe. I guess I was hoping that someone might say something like, "When it says 6/12, that actually just means anything up to 6.99/12." I have a hard time believing Duravent wouldn't have accounted for the fact that there are surely roofs like mine out there.

Is there any consensus on using an off-brand flashing? I'm happy to spend the big bucks on the quality class A pipe and roof support bracket, but for things like flashing and storm collars, couldn't I fairly safely go off-brand, as long as diameters match? Seems like an extra tube of high-temp caulk is nothing compared to what I'd be saving.
 
I generally like to stay with a complete system from one manufacturer.
Although others may fit, lots to be said for quality.
 
Because, as he described, the brand name flashing goes either up to 6/12 or starts from 7/12 pitch, and his is 6.5/12...
 
If it was on the ground and easy to access I'd take a chance on the cheaper one.

If there really is a gap in the compatible roof pitches, I'd go with the 7-12 one. That way if you end up having to cut it the notch will be on the downhill (taller) side.
 
Thanks for the replies. Yeah I tend to agree, all things considered, that it's better to go with the OEM when you're talking about parts that gear togethter in some way, and which are safety-critical. But if it's more or less just a piece of metal which keeps the weather out, and which will need to be fudged anyway--bent, cut, caulked--I have a hard time justifying paying the Duravent premium.

It's pretty easy access, so maybe I will go cheap. But that's a good tip, gthomas, thank you.

Thanks again, everyone.

If you go with Selkirk /duravent there’s a cheap kit at Lowes that includes it. Let me find it. Also note that the Selkirk pipe is like half of Lowes price on Amazon.

Edit, here’s the kit: https://www.lowes.com/pd/SuperVent-5-Piece-Chimney-Pipe-Accessory-Kit-for-Ceiling-Support/3134415

In guessing that either kit will work fine, the flashing is flexible, and easy to manipulate.
