A high-quality, properly installed roof is built to last. Even still, roofs aren’t invincible. By scheduling annual roof inspections and staying on top of homeowner maintenance, you can prolong the life of your roof.
However, most roofs are at the mercy of the weather. After intense storms or gradual wear and tear over many years, your roof can sustain damage. It’s vital to watch for these 15 signs of roof damage so that you can schedule roof repairs ASAP before it turns into a larger, more expensive issue.
Types of Roof Damage on Asphalt Shingles
Asphalt shingles are the most popular roofing material in the country and our material of choice here at Tidds Roofing. Modern architectural shingles can last up to 30 years with proper maintenance and lucky weather. However, asphalt shingles can develop these damages, especially as they age past 12 years old.
1) Curling Shingles
Bad attic ventilation is at the core of curling shingles. You can pinpoint curling shingles by lifted corners that peel upwards. They can also be caused by excess moisture on the roof deck. This issue is most common when asphalt roofs are nearing the end of their lifespan.
2) Cracked Shingles
Splitting shingles are most commonly caused by temperature changes. When the weather gets warmer, the shingles expand, and when it gets colder, the shingles contract. This process can cause the shingles to tear.
3) Blown-Off Shingles
Wind storms are not very friendly to asphalt shingle roofs— especially older roofs or those built with cheaper 3-tab shingles. A strong gust of wind may blow off a shingle (or a few!). You can often spot this issue from the ground, and it should be repaired right away to prevent water damage.
4) Shingle Granule Loss
When a hail storm strikes, the ice can dent your shingles. Most notably, the granules, which make up the sand-like outer layer, get knocked off by the hail. The result looks like small bald spots scattered across your roof. The granules act as the primary layer of UV protection, so if you sustained hail damage, consider filing an insurance claim.
5) Lifted Edges
Sometimes, roofing nails or the caulk can come loose. You may notice certain shingles flapping in the wind. This means that the edges are no longer secured. This is a simple fix for a roofing contractor to complete.
Damage on Other Roofing Materials
Even though asphalt shingles are the most popular material, not everyone has an asphalt roof. The following instances of damage more commonly affect materials like:
- Cedar shakes
- Clay tiles
- Flat roofs
6) Rusted Metal
Metal roofs often last more than 50 years, and they stand up well to wind and hail. Roof damage is less common on metal roofs, but they can experience rusting when exposed to excess moisture. The correct metal coatings help prevent this.
7) Splitting & Rotting Wood Shakes
Cedar shakes or wood shingles are aesthetically pleasing, but they’re more finicky than other materials. One of the most common issues that arise with cedar shakes is splitting after hail impact. Additionally, they can rot when exposed to the elements.
8) Cracked Tiles
Clay, concrete, and slate tiles are incredible materials that can last up to 100 years or more. They’re very durable and rarely sustain damage. However, certain weather impacts like hail may cause a few tiles to crack. Be sure to have the tiles replaced as soon as possible.
9) Pooling Water on Flat Roofs
Flat roofs are most common on commercial buildings and multi-family housing structures. Flat roofs are technically not perfectly flat because they need a low slope in order to properly shed water. If you notice pooling water on your flat roof, that means the drainage is not working correctly.
Damage That Can Affect Any Roof
While some damage is specific to the particular type of roofing material, other types of roof damage don’t discriminate. No matter your roofing material, keep an eye out for these universal signs of damage.
10) Damaged Flashing
Flashing is a thin metal material that gets installed in areas of your roof that are more prone to water damage, such as:
- Roof valleys
- Drip edges
If the caulk or nails come loose or the flashing begins to rust, you can quickly develop a water leak.
11) Falling Debris
Large tree branches are the biggest culprit of falling debris that can damage your roof. If you’re unlucky enough, a large tree branch may puncture a hole in your roof. It’s important to have professionals trim any branches that extend over your roof so that you’re at less risk. Of course, call a professional roofing contractor immediately if this happens to you.
12) Mold or Algae Growth
Over many years and decades, algae can begin to grow on your roof. If spores land on your roof and there’s already excess moisture in your roofing system, mold and algae will thrive. Not only is this unsightly, but it presents a health concern and the potential for water damage inside your home.
13) Rotten Roof Deck
The plywood roof deck is the first layer of your total roofing system. The felt underlayment and your shingles (or other material) are laid on top of the roof decking. Usually, roof decks last a few decades, but if any water seeps under the first few layers, the plywood can start to rot.
Sometimes, this issue isn’t spotted until a roofing contractor is already tearing off your materials for a roof replacement. At its worst, roof deck rot can cause structural damage like roof sagging, which is an incredibly urgent issue that could result in roof collapse if left unaddressed.
14) Clogged Gutters
Gutters are essential for a properly working roofing system. If they’re clogged, the water runoff has nowhere to go and can easily get forced under the edge of your roof. Be sure to clean out your gutters at least twice a year.
15) Ice Dams
Ice dams aren’t as common in North Carolina as they are in areas with more intense winters, but poor insulation and ventilation are at the core of this issue. If snow or ice melts at the top of your roof, trickles down, and then refreezes at the bottom of your roof, you’re dealing with an ice dam that can cause structural damage to your roof. Add more insulation to your attic if you notice ice dams forming in winter.
