I'm a big fan of you guys but I'd be firing guys if they did a valley like that lol leave the videos on installation up to me 😂😅

Does GAF not recommend the "speed valley" or "lazy man's valley" or "California valley" method? And in those installations, do those tabs catch and hold water being they are perpendicular to the valley?

Other methods weave the first course under the other side. See other GAF valley types video

Is this also called a Boston Cut Valley?

That is definitely not enough roofing cement for tropical central Florida though. Or anywhere actually. Not what tubes of cement are meant for to be exact

"do not put nails within 6" of valley"- immediately shows nails installed about 2 inches from the center of the valley
