Many homeowners assume that if their roof is not leaking, it must be fine. However, you can save yourself a lot of headaches--and money spent on repairing water damage--if you learn to spot signs of roofing damage before leaks even occur. Here are four more subtle signs that indicate it's time to call your roofing company because leaks are just around the corner.

Granules In the Gutters

As your shingles age, the granules on their surface start becoming detached, rinsing off the roof and into your gutters. A couple of granules here and there are generally not a cause for concern, but if you're scooping handfuls of granules out of your gutters, your shingles are near the end of their life and it's time to call your roofing company. Chances are, you'll need to have your roof replaced because without the granules, the shingles won't be able to do their job of repelling water much longer.

Pay attention to whether the granules are found evenly throughout your gutters, or if one side or section of the roof seems to be "shedding" more than the others. If just one area is shedding, this could indicate that this section of roof is being exposed to more sunlight or moisture than the rest of the roof. Your roofing contractor may recommend using a more durable, heat-resistant shingle to prevent the same issue from happening with your new roof.

Peeling Shingles

Before shingles completely go missing and lead to leaks, they often start to peel up along the edges or in the corners. If there are just a few shingles peeling, your roofing contractor may be able to just replace those shingles rather than replacing the whole roof. It's important to replace peeling shingles promptly because if they are left in place and leaks develop, the wooden underlayment could begin to rot, causing the roof to sag.

If the shingles along the edge of your roof are peeling, especially after winter, this could be a sign that your attic is not properly insulated. Inadequate attic insulation causes ice dams to form along the edge of the roof. The ice can work its way under shingles, leading to peeling and eventually leaks. Adding more insulation to your attic will help ensure your new shingles don't suffer the same fate.

Missing or Damaged Flashing

Flashing is the metal material that you see around the edges of chimneys and in valleys where two sections of your roof joint together. Sometimes, this flashing starts to peel away or work itself loose. When this occurs, water can begin seeping under the nearby shingles, leading to leaks and underlayment damage.

If you act quickly, your roofing contractor can probably just replace the flashing and perhaps a few of the surrounding shingles. Ignore this issue, and you may find yourself in need of extensive roof repairs down the road.

Excessive Moss Growth

A little moss here and there won't typically lead to leaks, but what starts as a little moss can quickly turn into a whole colony of moss--and before you know it, a whole roof full of damaged shingles. The moss eats away at the shingle material as it grows. If you're confident on a ladder, you can generally scrape and sweep away the beginnings of a moss problem on your own.

However, if there's more than a patch of moss here and there, you're best off calling your roofing company. They may need to not only remove the moss, but also replace some of the more damaged shingles before leaks begin to develop.

Don't wait until your roof is leaking to call a roofing company. If you ever notice any peeling shingles, damaged flashing, moss growth, or excessive granule loss, contact Recommended Roofers before things get any worse.
