Replacing your roof in San Antonio, TX, before it completely deteriorates is the best way to keep your home in top-notch condition.

In fact, roof failures can be costly and leave your home vulnerable until they’re repaired. As a homeowner, it’s essential to pay attention to your roof and conduct preventative maintenance when required. 

We recommend performing roof inspections twice a year, once in the spring and once in the fall. This way, you can find signs of damage before they turn into full-blown leaks or permanent damage. This in-depth guide will discuss the key warning signs that your roof’s lifetime is coming to an end.

1. Leaking Attic

Before you even step outside, it’s important to examine the interior of your home. So head up to your attic with a flashlight and go up under the eaves. 

Examine your attic for beams of light coming through the roof of your home. Furthermore, look for stains or streaks. These indicate that your roof is leaking. If you notice either of these warning signs, there is a high chance you’ll need a roof replacement from professional roofers.

Roof leaks occur for a variety of reasons, ranging from storm damage to worn-out materials. When your roofing materials weaken, water often leaks through your shingles into the rest of your home. Although small leaks are easy to repair for professional roofers, they often go undetected until they evolve into significant problems.

Large leaks in your home may require an entire roof replacement. However, the best way to inspect your roof and know for sure is by calling on a professional roofing company.

2. Aged Roof

Another helpful way of determining whether you need a roof replacement is checking when your roof was installed. Although proper maintenance can extend the lifespan of your roof several years, it will still need to be replaced at some point. 

In fact, asphalt shingle roofs last 20 to 25 years, and roofs installed over a layer of existing shingles need to be replaced after 20 years, so it’s important to have your roof inspected by professional roofers if your roof is older than two decades.

3. Damaged Shingles

Once you’ve examined your attic and the interior of your home, it’s essential to get an in-person look at your actual roof. Examine your roof for mossy, missing, or curly shingles. If you notice any of these issues, it may be time to replace your roof:

  • Curled or damaged shingles
  • Cracked shingles
  • Missing or loose shingles
  • Discoloration or damage around vents
  • Algae or moss growth
  • Damage around skylights or chimneys
  • Missing granules

We also recommend inspecting your home’s gutters for shingle debris. If you find shingle debris in your gutters, it’s a clear warning sign that your shingles are beginning to deteriorate, and you’ll need a roof replacement.

4. Sagging Roofline

If the shape of your roofline isn’t straight, your home may need a roofing replacement. As such, check your roofline to ensure it isn’t sagging, curving, or dipping. Although a potential framing problem can cause a sagging roofline, a water-saturated roof deck can also produce this type of issue. 

Furthermore, if you notice a sagging roofline along with visible shingle damage, water damage, or leaks, it’s important to contact a professional roofer immediately to prevent substantial damages. 

5. Storm Damage

Storm damage may also warrant a roof replacement for your home. Heavy ice storms, hail storms, rainstorms, hurricanes, and tornadoes all have the ability to cause significant and lasting damage to your home’s roof. 

Make sure to examine your roof for visible signs of damage after a storm passes through your hometown of San Antonio, TX. 

6. Organism Growth

If you notice mildew or mold growth on your ceilings or walls, this is an indication of a leaky roof. However, the organism growth could also be caused by a simple plumbing issue. For this reason, it’s vital to get your roof examined by a professional roofing contractor in order to determine the source of the damage. 

Examine your roof for signs of:

  • Algae: This green and black organism can rot your shingles by eating away at them.
  • Mold: Mold can be seen as black, brown, and dark-green blotches.
  • Moss: Moss attracts moisture like a sponge and can cause permanent roof damage.
  • Mildew: This growth is commonly found on wet surfaces and is characterized by light-gray to black or pink blotches.

If any of these growths get too bad, you may require a new roof.
