did aliens land on this roof? please help a gal out

Ok so this is an embarassing post. I ought to know what made these marks, but I want to get opinions from you seasoned professionals before I trust my inkling that it's a manufacturer's defect. I could see these marks from the street. They're all over the roof in a random pattern... It was pretty steep so I only dared to get valley shots.. Please tell me what could have damaged the shingles like this. Also, here's a picture of some nail pops.. What causes this and how can it be prevented?

Thanks so much, Cha

I have seen this before. This is a defect in the shingle, and yes their is a class action suit against this defect. I have also seen new construction roofers put on a bad roof right from the pack. They don't care and the mentality is "You can't see it from my house". They get paid by the square and don't care if the roof looks good or not. Seems that it's a dying breed of taking care of your work, the quality of America has gone down. Sure wish I could help, but when I seen this I couldn't help even after following all the levels of red tape... The shingles may still work, but who wants a crappy looking roof on the place they live?

i cant even see the pics

It looks like heat damage.How's the ventilation on that house?

How old is that roof? I guess it could simply be defective shingles that the sun ate up in a hurry! Its weird that every mark seems to be on the double layered portion of the shingles. I dont see any on the single layer portion.

Ole Willie yeah I agree with that.. It's ALL OVER the roof.. Cannot be foot traffic. But if they came out of the pack like that, wouldn't someone have noticed once the job was done? You can literally see the marks from the street. It's nuts. I'm interested in seeing what the adjuster says.. if he climbs it :blink: thanks to everyone who responded.

Those shinlges came out of the pack like that. May be second rate materials. I dunno. But my question is why did the roofer use them when it was obvious they were damaged. Its not foot traffic. If you look at the pics the shingles are damaged on the very edge of the roof including the overhang where even an idiot wouldn't be dumb enough to walk. lol
