This one is easy to spot right away. Since shingles are the outside layer of the roof, you should be able to identify damaged (or even missing) shingles by seeing different-colored patches on your roof, typically darker. You may even find the shingles themselves littering your yard after a heavy storm.
Why Shingles come off: Our frequently windy Spartanburg weather, or very heavy rains.
How To Fix It: Slide a pry bar under the row of roofing nails that connects the damaged shingle to the one under it. Lift it up until the nail head comes out and then press down on the shingle while you remove the nail completely. You’ll need to do this for each set of nails around each shingle. Pull out the damaged shingle, replace it with a new one, and secure it with four new standard roofing nails.
What if Your Valleys Are not Sealed Properly?
What Does This Look Like: Any area where two parts of your roof come together. Since, these areas of the roof are usually sloped at an angle, when the valleys are not sealed together properly, rainwater will get inside your attic or home as it runs down the roof. You can detect a problem by searching for wet areas along the seams of your roof.
Why It Happens: Several reasons can cause these issues – the outer sealing may not have been done properly when it was built so it may have cracked when being stepped on for finishing work, or even an excess of rain and ice may have caused it to become eroded over the years.
How To Fix It: This is one of those things that really needs to be done by a professional because of the complexity and we do not recommend homeowners attempting it on your own. This is a common problem, especially with older homes, so our roofing technician will likely fix the problem by laying a new and reliable leak barrier along the valley and the shingling overtop.
