Two year old shingles lifting
Hello everyone,
I have a question about my shingles.
We had them installed a year and a half ago in the fall. The first spring we noticed them lifting a bit. We called the contractor and the installer came back to look at them. He said that they should lay back down as the weather warmed up.
This spring it is worse. More sections are starting to lift (see pictures as long as they worked). Is this something I can fix with some nails and some tar or should I be holding the installer accountable?
Thanks for your help.
Andrew

It wouldn't surprise me if the lifting is caused by sheathing joints that aren't flush with each other. A slight discrepancy, even just 1/8" difference between adjacent panels of plywood, and the shingles will never lay down flush. Was new sheathing installed during the installation? And if so, were plywood clips used at alternate rafter (or truss) spaces?

Welcome to the forums.
I'd have to agree with Bridgeman as you can see that the shingles are lifting in rows. More than likely right at the seam locations.

It can also be caused by moisture escaping those plywood joints when you have high humidity and not enough ventilation. Wind turbines are often not the best at ventilating attics evenly. I've never seen one put that low on a roof.

Thanks for the input. New sheathing was not installed. All they did was remove our old shingles and install the new ones. Our old shingles did not look like that before they were removed.
Sounds like I will need to get in touch with the contractor so I can get this fixed properly.
I'm glad there are forums like this.

You might be able to get a better grasp of what's causing the problem if you ask the shingle manufacturer's regional technical rep to come out to take a look at it. A good one with some experience under his belt will know what the roofer did wrong (if that's the case). He/she will at least have some suggestions for correcting the problem.
What weight of roofing paper (felt) was installed before the shingles went on? And was it allowed to weather, or otherwise improperly fastened?
