Perhaps you were entering your driveway when you noticed the shingles on your roof. “Is it supposed to look like that?” you had probably wondered. When taking a detailed overview, you realize that the shingles on parts of your roof appear to be curling upwards. Curling shingles are an indication of a problematic situations, and it is a sign that you must repair before bad weathers worsens the condition of your roof. But on another note, you’re probably pondering how your roof came to be in the condition it is now.
The first common reason for the curling of your roof’s shingles is poor attic ventilation. Inside of your home, hot, moisture-filled air commonly rises to the attic. If your attic is well-ventilated, this should not be a complication for the fact that the excess moisture will be circulated around and pushed back out of the attic. On the other hand, if your attic is poorly ventilated, all of the moisture from the rising air tends to get trapped in the decking, which will cause mold to form, and as a result shingles curl.
Another familiar reason your shingles might be curling because of is if you are the owner of multiple layered roofs. In many cases, homeowners opt to lay a second roof on top of an old, decrepit one. While it’s not frequently recommended, many people choose this option because it’s much cheaper than stripping the old roof and starting over. And although this action saves on upfront cost, this usually leads to premature shingle curling. The shingles on the second layer of the roof won’t be as secure, and are easily blown and curled by high winds.
Improperly installed shingles is one of the most common reasons that shingles curl. The problem begins when whoever installed your roof didn’t use enough nails per shingle, or improperly placed the nail. Either way, this will surely cause your shingles to curl. If there aren’t enough nails holding the shingle down or the nails are placed in the wrong spot, it’s likely to work itself out over time, leaving the shingle loose.
The cause of your shingles curling may also be because your shingles were not lined up correctly. There’s an adhesive strip called a tar line on each shingle. If the tar line isn’t lined up by a professional on each shingle, it won’t adhere properly. Which means your shingles will eventually curl or could potentially fly off.
Age is the most popular reasons for curling shingles. Putting it simply your roof just might be too old. If you have an asphalt roof that was done more than 12-15 years ago, and the shingles are curling, it’s probably time to get it re-roofed. You’ll save yourself a lot of time and money if you redo it now, before the shingles become a real problem and begin to let in water.
If your roof’s shingles have begun to curl, no matter the reason, it’s probably a good idea to get them replaced. Curling and missing shingles mean possible leaks in your roof, which can eventually lead to water damage – a much bigger problem.
