The general rule of thumb to replace your roof is after 25 years. However, this is not a set rule, as there are various factors involved that can reduce the lifespan of the roof. They include your local weather, yearly maintenance, age and quality of materials, pest and rodent infestation, and accumulation of debris on the roof.
Therefore, it is necessary to recognize the signs that tell you when to replace your roof. You need to remain vigilant when it comes to your roof, keeping a look out for the following signs, according to the expert South Jersey roofers at High Point Roofing:
1. Missing Shingles
You can replace old shingles with new ones, but you’ll run into a problem. Finding a new shingle that matches the color of your old shingles is not easy because granule colors have changed over the years. Additionally, the weather also changes the color of shingles.
You can keep replacing the missing shingles with a color that’s similar to the existing shingles, but if it keeps happening, you’ll have a checkboard for a roof. It’s better to replace the entire roof.
2. Curling Shingles
Curling shingles is another problem. Shingles can curl in two ways, cupping and clawing. Cupping occurs when the shingles’ edges turn upward, and clawing occurs when the shingles’ edges remain flat with its center up. This can result in leaks, if not fixed. It’s safe to say you will need a new roof within 5 years or less, depending on the severity of the curling.
3. Accumulation of Moisture and Mold Growth
An improperly vented attic causes warm and moist air to become trapped inside. This causes condensation on the underside of the roof, which then results in mold growth. Failure to fix the problem can cause the plywood to rot, leading you to buy a new roof. If the problem has gotten out of hand, you’ll have to replace your roof with a new one as well as look into insulating your attic properly.
4. Daylight Streaming through the Roof
If daylight is streaming through your roof, it signals that the nails have come loose, or corrosive materials used no longer have their weatherproof properties. You’ll need to replace your roof to prevent moisture from entering your home.
5. Sagging Roof
One of the biggest indications on when to replace your roof is when it starts to sag. A sagging roof means that you’re dealing with a structural issue. Look for a droop or depression in the roof to determine if your roof is sagging. There could be an issue with the supports in the foundation of the house or the decking in the attic. Even though you’re not in any immediate danger, you should still get a new roof right away.
