The black could be algae or dirt line from all the water/dirt running down the center of the shingle due to the curling, or tar - the latter in hot areas only, where it gets hot enough in the sun to melt the tar.


I would call the roofer back to look at it - with respect to whether he thinks this is a materials defect or not, though at that age most warranties would not cover labor - only possibly eligible for replacement shingles from the manufacturer.


As for "fixing" it - no, you cannot do anything within reason to uncurl shingles. However, while curled shingles are generally an indication that they are starting to weather significantly and starting to near their lifespan (though manuy go a decade or more after start of curling), as long as they are not actually trapping water in the "cup" formed by the curl, it actually may not daramatically affect the roof life or cause problem, because there is another layer of shingles underneath to catch the water missed by the curled edge. If it starts curling up at the tip is where it quickly starts deteriorating, because the curled tip retains water so the shingle gets soft (so blows back easier) and starts deteriorating from the constant water exposure and algae growth.


However, curled shingles ARE more prone to wind damage because the curled corners/ends catch the wind better, so in some areas that can lead to more blowoff in strong winds.


But, unless the manufacturer will replace them as defective materials, up to you whether to replace now or wait till they start showing significant surface deterioratioin and cracking. Personally, I would not if they are not showing trapping of water due to end cupping, or significant surface deterioration including possibly major loss of granules or swelling up of the shingle due to water absorption. Of course, organic (naturall fiber) shingles are a lot more prone to this absorption issue than synthetic fiber (usually fiberglass) ones.


There is a Class Action against Certainteed for their organic shingle line - which if you have not already filed a claim might cover you up to the original shingle wrranty period, but the claim period expired in 2011 for some types/classes of claimants - link here for more info -

There is also an attempt to start another class action suit basedon some homeowners not knowing of the first one or reasonably being notified - google "curling Certainteed shingles suit" for more info on that.



BTW - copuple of links here on black streaks and extending the life of your roof FYI:
