newly installed asphalt looks horrible (See Pics)
Majority of late fall,early winter,winter and early spring installs look like pooh.
The shingles are stiff and don't form to the roof very well.Extra care should be taken when shingles are installed to form into valleys.Ridge cap is another item that cracks if not pre bent.(Holding about 10-15 ridge caps and bending all at once over the knee)
If air pressure is not monitored then fastener blow through due to excessive air pressure will occur.A blown fastener passes thru the shingle fastened and the shingle below.The fastener will leave the hole but will not secure any part of the shingle.
During cold applications the shingle packages will take on the shape as they were loaded on the truck or how the were palletized in the factory,suppliers warehouse and they also take on the form after they have been loaded roof top or in your driveway.
From what I can see with your install the opening of the valley looks like it is broke.,possibly from walking in it due to the steep pitch.However steep pitch or not.,,its never a good idea to walk in a valley regardless of season.
The offset (Stagger) looks a bit funny.The roof shows a vertical pattern.Almost as if the shingles were racked.Another way I can tell that it might possibly had been racked is this.If you look at the rake.The rake can be cut several ways.1st by completing the entire rake then popping a chalk line and cutting it continuous.2nd by installing several courses up the rake then flipping a full shingle vertical flush with the starter then using the straight line from the shingle to make a clean cut.3rd by cutting each individual shingle to fit as your working up the rake.
Your rake shows the entire height of shingles that are sticking out further and shorter then flush from course to course.So that means the factory edge is to the outside rather than the factory on the inside and the cut on the outside.I am sure I just confused the hell outta everybody but I guess its hard to explain.And of course everything I just said is blown out of the water if your roofer was left handed. Hahahaha
Without seeing pix from the roof top and by seeing nail patterns or butts then to me it looks like a run of the mill cold weather application.Hopefulyl for your sake some warm temps will help it relax.
I am not saying that what the other posters are saying isn't true.I am just replying to what I see.
I contacted several manufactures personally about racking limited and lifetime shingles and this is what they said quote "Racking Architectural shingles is NOT a recommended installation procedure for their shingles"
