If you are like a lot of homeowners, when you think about a damaged roof you envision things like shingles showing up in the yard or other problems a bit more obvious. However, when it comes to an asphalt shingle roof, there can be damages that are not so apparent. As a homeowner, it is a good idea to get to know the not-so-obvious signs that your asphalt shingle roof is in trouble, as the faster you tackle issues, the less likely it will be that you see further problems. Here are a few of the sneaky signs that your asphalt shingle roof is in need of a few repairs.

You notice a sudden spike in your cooling or heating bills. 

In some cases, the damages to a roof will be so well hidden that you will have no idea that anything is happening until you see a major spike in your heating and cooling costs. It is not uncommon for damages in a roof that are unseen to lead to heat loss in the winter or allow more hot air in than usual in the summer. So if you see a sudden and unexpected jump in how much your heating or cooling costs are, it is best to check out your attic inside the house and the roof on the outside to look for signs of damages. 

Your roof appears wavy from the ground. 

Asphalt shingle roofs are installed in a way that the end result is a completely uniform and level appearance. Therefore, if when standing from the ground you notice the roof seems wavy or uneven, there is a good chance something is awry. It could be a few missing shingles throwing the surface off kilter or something as simple as a few shingles which have curled or bowed. Either way, it is important to have any discrepancies checked out right away. 

You start noticing a hefty amount of roofing granules in your gutters. 

The sand-like granules that are adhered to the surface of asphalt shingle roofs are fairly resilient, but if a shingle itself gets damaged by wind or excessive amounts of moisture or ice, these granules can detach and make their way to the gutters. While a lot of granules will show up naturally as a roof ages, if your roof is fairly new and you start seeing this symptom, it is a good indication that something is wrong.
