Why Are There Waves In My Roof?

We went by the house today and noticed that the roof over the garage has waves in it.  This worries me.  I'll have to ask about this on Monday.   Other than that, the garage doors were installed and the HVAC work has begun.

  3. I noticed the same on my old house when we replaced the roof and a little bit on the new one during construction. Eventually they both went away. I think the shingle strips need a good hot day to stick to each other or something... Don't worry about it too much though.

    1. It worries me, because the rest of roof appears flat.

  4. The waves in the roof are one thing and may clear up as Mike says, but I have to be frank that the shingles at the apex roof would also concern me since it looks like there are several that are not secured. Maybe it is nothing, but it is something I know I would bring up with the PM.

    1. I spoke with my PM about this today. He said that the framers are going to take a look at it this week.

  5. On our old house 4 years ago we put on a roof and it can be like that. It's normal and will lay better over time.

    1. My PM is sending the framers out to look at it this week. The roofs in my mom's neighborhood look like this, because they used flimsy plywood on their roofs.

  6. That is a very good question. Roof waves can be caused by warping shingles, and there are lots of reasons for that to happen. One is sunlight and the high moisture level on the roof. Another is improper nailing. It can be that the shingles are nailed too tightly or the nails popped up, creating a buckling effect on the roof. Depending on the cause of buckling, improving attic ventilation to eliminate excess humidity, or refastening distorted shingles are some possible solutions.

    1. Thanks for the insight. My PM said that the hot sun will heat up the shingles and glue them down. I'm going too see if it has improved any.

  7. It is good that you spotted this early on, Maria. Roof waves are a minor problem at the beginning, but they can cause some major roof issues in the future, such as leaks and mold formation due to moisture trapped under the shingles. It is also unpleasant to look at, that is why it is best to repair it immediately.

  8. Hi Chantay,
    I have to check it again to make sure they are gone. They said that they fixed it and that the heat should help it lay down flat. Thanks for the tips.

  9. From the photo, the roof really doesn’t look right. It is a good thing that you have a keen eye and spotted it right away. It would be very troublesome to redo the roofing again if you did not notice the problem after the house is completed. I just hope the problem with the roof is already settled. And that you post some pictures of your house when it will be finished.

  10. I’ve seen your latest post about the house, and your house is looking beautiful! You seem to have settled down quite nicely, and it definitely seems like the waves on the roof above your garage have flattened out quite nicely. It seems you’re working on the making lawn greener right now, and that’s definitely going to take some time to work out. But be patient and hang in there. Before you know it, everything will be finished and you’ll have a place you can truly call your own!

  11. That is troubling. Warped roofs can be caused by too much heat or exposure to moisture. But I think the heat is the culprit here because of the color of your roof. Dark colored roofs are known to attract too much heat, which can shorten the lifespan of the roof. Anyway, what did your PM say about it? It is a costly mistake, just think of the effort and time redoing the job.

    1. The roof looked like that right after it was installed. My PM said that the heat should help melt the tar and flatten it out.
