How you know its time to replace your roof

The massive granular loss was found from being exposed to weather elements for so many years.

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

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

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

The two pictures on 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 then the center of the shingles should be cut out. See the bottom picture for a proper pipe boot installation.

The step flashing is designed to go between each shingle. In this way, the watersheds can go down to the roof all the way to the shingles. The step flashing is sitting right on the wood decking. If they were between each shingle then I would not be able 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 and as you can see all was smashed and bent up under the shingles. This will be the reason that the water can go directly inside.

In the top picture, you can see that the shingles are starting to slide down in 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 will hold them down, then gravity will be going to pull the shingles down to the roof that could possibly be the cause of the collapse.

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

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

These shingles are overlapped but most probably it should 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 shingles that are sticking up. This will happen due to the worst overlapping of shingles.
