The roof is arguably the most important component of your house. If the shingles on your roof curl that’s an indication that something is wrong. Below are 4 reasons why your shingles are curling.
1. The shingles on your roof were improperly installed.
If the shingles on your roof weren’t put on correctly, this is the main culprit for curling. Due to whomever installed the roof probably didn’t use enough nails or placed them inadequately. Consequently, the shingles work themselves out over time, leaving them loose or curled. If the adhesive strip or tar line isn’t lined up next one another, those shingles will eventually curl or even fall off.
2. Your attic space is not properly insulated or ventilated.
A roof ventilation system works by pulling in outside air from intake vents placed on the lower part of the roof. In your home, hot, moisture-filled air typically rises to the attic. This will not be a problem if your attic is well-ventilated. Because a well-ventilated attic circulates excess moisture, whereas a poorly ventilated one, traps moisture in the decking, this causes mold to form and as a result, shingles to curl.
3. Having multiple layered roofs – Yes, you heard that right!
Some homeowners out there that opt to lay a second roof on top of old one. This option shouldn’t be condoned, but people still choose this over getting a new roof because it cost less. Certainly it saves money upfront, but usually leads to premature shingle curling, costing you more in the long run. Another reason to shy away from layering your roof is that the second layer of the roof won’t be as secure. High winds can easily blow them off your roof or curl.
4. Old age is one of the most common causes of curling.
If you have an asphalt roof that was done more than 15-25 years ago, and the shingles are curling, it’s time for a new roof. Don’t wait to get a new roof. Save a lot of time and money if you don’t delay. Not only do shingles fall off and curl, but they also let in water, which can be a bigger headache down the road.
