Curling shingles are a design feature to make roofs more resistant to hail storms, snow, and ice. When the snow melts and falls on the roof it travels down the chimney or through the vents in the roof and causes excess moisture in the attic. If not caught early enough, this water can cause damage to the interior of the house by causing water damage to drywall, paint, and ceilings. This is why the design of curling shingles is so important for protecting your home.
If you notice that your new roof leaks, then this is a sign that you need to repair the roof immediately. A small leak may not seem like a big deal but when you add up all of the water damage that can occur, it’s definitely more than worth it. Take note of where the leak is though. It’s not necessarily where the leak is but rather where it’s coming from. For example, if the leak is coming from the bottom of the attic then you need to check the ceiling to ensure that the problem is with the tacks underneath the roofing instead of somewhere else.
If you have an asphalt shingle roof then the most likely cause of the leak is some form of cupping. When water makes contact with the asphalt shingles, it will form a protective layer against the moisture. The moisture then slowly seep out and get trapped at the edges of the shingles, which causes them to curl up. While this is a great design feature for asphalt shingles, they are not the only type that can develop cupping. If you notice any signs of cupping shingles, then it is highly recommended that you replace the shingles immediately.
Another common cause of roof damage is damaged or missing shingles. When you replace shingles, the first thing you should do is make sure you have a layout plan for your job. This will allow you to know exactly how many tiles you will need to cover the area, which will in turn dictate the materials that you purchase. For example, if you are replacing single tiles then you will want to purchase a high-quality tingling material, while if you are replacing entire roofing sections then you will want to use a low-quality material such as fiberglass.
As with asphalt shingles, older roofs can also develop problems with their tiles becoming cupped. In older roofs, however, the damage may not be readily apparent. Asphalt roofing tiles are generally covered over and often sealed so that they cannot be seen. However, for the proper installation of a new roof, the older roofs will usually have to be removed before replacement.
It is very important that when removing the old roof that you make sure there are no items such as nails or shingles within your work area. These items can cause granules to build up around the nails and shingles, causing premature roof failure. Once the old roof is removed, it will be your responsibility to install the new roof over the top of the existing one. During this time it will be your responsibility to check the ceiling for any leaks. If any leaks are found, it is important to repair these leaks right away to prevent damage from occurring down the road.
As you are installing the new roof, it will be necessary to inspect the ceiling for any missing granules. Sometimes this is caused by poorly installed flashing around the ceiling. In other cases, the missing granules are caused by the improper cutting of the shingle pattern.
Although blistering can occur with shingles it is usually less than with other types of roofing. Blistering can occur with any type of roofing whether you have organic, fiberglass, or wood shake. If you have any questions about how your roof may be leaking you should consult a roofer. There are some cases where blistering can occur even with organic materials but in most cases, organic materials do not cause blistering issues.
