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'll bet that the asphalt had cooled when they put on the second layer of granules and the granules just sloughed off. That is probaby the reason they don't make them anymore.

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

I think the one with the holes in it by the gutter is just pressure due to the fact it is being forced down as it is tucked behind the gutter. The way the valley lies leads me to believe it is a go over which can contribute to the nails rising due to the extra heat. "Nail pops" are due to the rate of expansion of the metal nail being quicker (and more dramatic) than the wood deck. The skuff marks leave me puzzled.

Some of the smudged areas look very similar in pattern. I wonder if the manufacturer's granule applicator in the manufacturing line had an issue?

the one by the gutters,looks like holes left from a scaffold pole roof brace,tha rest looks like foot traffic in the hot sun,the horizon scar easily when its hot,more so on the applied pieces

That looks like the certainteed horizon line that has been discontinued -- If the marks are in the double thickness area it is a known manufacture defect (blister) Certainteed is going through a class action right now saying "The shingle still performs and will continue to perform" So there settlements are prorated like 2-5 years max and just materials-- i do see some mechanical as well from walking on it? The one in the gutter has probably had them tiny holes since day one? your guess is as good as mine with that?
