So I'm FINALLY (!!!) getting my new roof. Roofers come tomorrow to tear off; weather is finally cooperating.
Once the cathedral ceiling roof sections are gone, the insulation remover guys will suck/pull out any insulation in the rafter bays.
During all this, the expanding insulation spray foam guys will be in my house filling up stud bays in my living room and the crawl space under my house.
When the roof rafters are clear, they will fill those up as well.
During all this, the solar pool heater guys will be on the uppermost roof roughing in some plumbing and brackets for their install after the roof is done.
Some day down the road, I want to put up PV (photovoltaic) solar panels for electricity generation and this brings me to my question (FINALLY!!!).
I have a 1.5" and 2" vent that I wish to move in order to get them out of the way so that PV panels can be installed more easily and cleanly.
My roof pitch is 3:12 or 15 degrees (as the industry claims but do the math and it is 14 degrees) and I want to move the vents higher up on the roof as close to the crest of the roof as possible.
Basically, I'm looking for some plumbing fittings that give me a 75 ( or more correctly a 76) degree bend but, of course, no such puppy exists.
What we do have are 45, 22.5, and 60 degree bends out there. Or as the industry likes to call them: 1/8, 1/16, and 1/6 bends, respectively. Of course, there are 90 degree ones, too, or 1/4 bends.
So I need to combine these to get me close to 76 degrees so that I can take my vent and run it up along/near the top of my attic before it exits.
22.5 and 60 get me 82.5 (6.5 degrees too low)
45 and 22.5 get me 67.5 (8.5 degrees too high)
Now I realize there might be some code issues with this but I don't care; I'm moving the vents; no one needs to know about it 'cept you fine folks here at SMC. Besides, I honestly don't see how adjusting the vents will hurt anything in the least. They are being moved higher up the roof.
Cheers
