New roof question

[2515R Dude]

I want to replace my roof. I noticed some roof contractors make valley with metal (sorry, i dont know the terms, i guess it is valley flashing but might be wrong) and some just overlap shingles.
Does it make any difference and which one is the way to go in your opinion?

As long as you're looking for opinions, I don't use valley flashing at all. I'm a homeowner not a roofer so I can take the time to weave the shingles across the valley. If not properly installed with enough flashing on each side of the valley the roof may leak in a good rain. I put on a new roof to eliminate leaks.

That's the way I have done mine also, and I am not a roofer either.

I don't know why all roofing companies don't weave the shingles in the valleys.

Sometimes having metal in the valley is a plus. Leaves don’t hang on it as much as a woven valley.

I put rubber snow and ice shield in the valleys on my house and then laced the shingles over that being careful to not step or nail in the center of the valley. Maybe overkill but we have frequent freeze thaw cycles during winter so doing everything I could to reduce potential for ice dams backing water under shingles in the valleys.

In CA EVERY roof has valley flashing. In 13 years as a real estate appraiser I never saw other way.
Here in KY, 90% or more weave the shingles.
Now i want to put a new roof on my house and need to make an educated decision.

When I worked as a roofer in Vt. we always had metal in the valleys.

Is there any advantages? I guess the right question is: What is the best way of doing it?

I did some roofing years ago for a contractor and my wife had family in the commercial business of roofing. They all used metal valleys. Also tapered it a bit so it was wider at the bottom than at the top to aid snow from sticking/daming and good water flow. Also slicker than asphalt.
I suspect with the speed asphalt/fiberglass roofing is done today it is just faster, cheaper and requires less type of materials etc.
Choice is yours however. Both do work. Certainly make sure there is appropriate and wide enough underlayment in that area and near the gutters.

Peel and stick and then weave.
