excellent picture demonstrating how to do a closed valley.
We all do things different. The only thing i would have done different is i wouldn’t have brought all my shingles so far to the other side of that valley.
That roofer likes to bring his shingles a lil farther than the halfway center point of the valley.
I bring mine a lil shorter than the halfway point of the valley.
We do the same thing on the popping of lines.
PB, you said you didn’t understand what axiom meant with the lines. Look at his picture and you will see blue chalk lines popped on the felt in line with how the shingles go.
Axiom uses the first line measurement of 18 inches
up from the very bottom part of the roof.
I would do this too if i wasn’t using evedrip metal.
I use evedrip around the entire perimeter of every shingle structure i do.
So i start my first line measurement at 19 inches.
Axiom pops each new line up at every 22 1/4 inches.
I make mine at 22 1/8.
The crew if i am not there, will pop 22 inches even.
According to “manufacture specs” lol 22 1/4 would be the measurement. But i find that there are too many exposed nails at that measurement. Because
I am a stickler for “NO HIGH NAILING”
I would rather have exposed nails(low nails), that i can fix and hide rather than the roof all being
"high nailed" = not nailed every time through the double thickness of the shingle)
and the roof leaks or blows off or falls out.
i dont care how many low nails there are.
No high nails.
And i tell my crew not to fix their low nails.
I fix every low nail on the job personally.
I make it look nice.
Other roofers(most) will argue with me
and they will tell you they dont have any low nails on their jobs. But the truth is, all their jobs are high nailed and crap in my opinion.
And i can run a hitachi/bostitch roofing gun like you have NEVER seen in your life. Fast and perfection.
The nails are in the double thickness of the shingle and flush.
If i shoot high(rare), i stop and put roofing cement over the nail area that i thought shot too deep. I am not afraid to get my finger dirty.
I keep some roofing cement on a spare shingle piece next to me at all times while i shingle.
Only one man have i seen besides me that does that
and i trained that man.
