discolored shingles

Need some advice, Have a 2 story home in upstate NY and my shingles are getting darker in the vincinity of the attic vents. Was wondering, if this is something to be concerned about?
I checked the attic area and nothing seems amiss

Thanks in advance Twodogs

Havent done any roofing in your humid climate, but I can offer a guess...... We have the same thing here in Arizona.....They're called pigeons...... OK, OK maybe thats not it.......I will guess that the discoloration is mainly below and maybe a lil on the sides of the vents.....Likely staining from the oils in the mastic or stained from the metal "aging"
