Creased Asphalt Roof Shingle – Lincolnshire IL

In the previous article we discussed being called out to inspect a wind damaged asphalt shingle roof on a Lincolnshire, IL house. We posted two pictures we took from the ground. The first showed the shingles apparently lying flat on the roof while another showed a shingle tab obviously missing from the roof. Of course, we could not determine the extent of damage until we actually got up on the roof and inspected further.

The pictures taken on the roof indicate several types of damage to the roof’s asphalt shingles caused by high winds.

In the first picture (above) notice the crease in the shingles. This crease, or fold, indicates the shingles were lifted by the wind pressures and bent up and down until the crease formed below the nail line. Think about folding a piece of paper back and forth and then tearing it.

In some instances the shingles may also be creased so badly that they “flip” over and lay flat on the roof with the normal underside exposed to the sky as shown in the picture to the left.

During exposure to very severe wind storms, failure in the form of detaching or dislodging full or partial strip of asphalt shingles can occur. Tearing occurs where the shingle, or entire tab, is not only creased or flipped, but pulls over or tears away from the nail heads. It then detaches from the shingle strip. Notice in the picture below the portion of the shingle that slid down the roof line in this picture.

Manufacturer warranties for wind resistance vary by grade of the asphalt shingles installed on your house. How long shingles are rated to resist high wind speeds depends on the grade of shingle installed. The better (and probably more expensive) shingle will resist higher wind speeds for a longer period of time. When looking to re-roof your home inquire about these ratings before deciding.

We will continue this discussion with additional photos taken during the inspection. To read the first article go to Wind Damage To Asphalt Shingles On The Roof Of Your House
