When should you replace your roof?

Nail pops, worn out shingles, lots of granular loss

  1. 1
    exposed fiberglass from granular loss

    The massive, granular loss was found from exposure to weather elements for many years.

    As you can see on this shingle, there is about 60 to 70 percent granular loss.

    Nail pops all over the roof

    As you can see in these pictures, there are nails that are just popping everywhere on the roof. If they don’t push through the shingle, they will push it up, creating a gap under it. As you can see in the bottom picture!

    Improper pipe boot installation

    The top picture shows the pipe boot that was exposed for too long. Massive rain and storm can make it under the edges and on the roof.

    In the two pictures in the center: the pipe boot should never be under all the shingles as this can allow rain to enter under the shingles. You can see the outlined bottom where the pipe boot should be coming out, and the center of the shingles should be cut out. See the bottom picture for a proper pipe boot installation.

    Improper chimney flashing

    The step flashing is designed to go between each shingle. This way, the watersheds can go down to the roof to the shingles. The step flashing is sitting right on the wood decking. If they were between each shingle, I would be unable to pick up the edges of 3 or 4 shingles at a time. I’m doing that in the second picture.

    The bottom picture shows the flashing at the top of the chimney; as you can see, all were smashed and bent up under the shingles. This will be the reason that the water can go directly inside.

    Sliding shingles

    In the top picture, you can see that the shingles are starting to slide down on the roof. In the second one, you can see that the nails were put in with too much pressure causing the nails to shoot through the shingles. If nothing holds them down, then gravity will be going to pull the shingles down to the roof, which could be the cause of the collapse.

    Moss growing on shingles

    Moss is horrible for a roof. The root system to moss growth is under and in between the shingles; it will cause them to be moist and will let the nails rust away.

    More nail pops

    They say that for every nail that popped, you can probably see 1-2 nails, but I noticed more than that.

    Improper installation of shingles

    These shingles are overlapped, but they should probably be butted up together. This can cause premature wear due to overheating, and the shingles will not seal down as they should. The bottom picture is the same as the top one, but I outlined the sticking shingles. This will happen due to the worst overlapping of shingles.
