6 Signs That Your Roof Shingles Need Replacing

Roof shingles are a popular, aesthetically pleasing, and cost-effective choice for many homeowners. Roof shingles are durable and impervious to rust, making them suitable for various climate and environmental conditions.

But, like with any roofing system, it is essential to know when to replace them. Knowing when to replace a roof shingle can be tricky, but there are certain signs to look for that can indicate it is time for a new roof.

1. Cracked, Curled, or Missing Shingles

Cracked or curled shingles are the most common signs of aging and deterioration. Shingles usually develop cracks because of extreme weather conditions such as high winds, hail, or heat. These issues can weaken your roof and lead to water damage and other problems. 

Missing shingles can also be a sign of aging and deterioration. This could be caused by extreme weather, but it could also be a sign of inadequate installation or poor maintenance. Missing shingles can expose your roof to water damage and other issues, so it’s essential to address them as soon as possible. 

2. Granule Loss

Granule loss is a common problem that can occur with asphalt shingles caused by the breakdown of the protective granules that coat the roof shingles. This results in the exposed asphalt being exposed to the elements. This can lead to accelerated wear and tear of the shingles, resulting in premature roof failure.

Various factors, including age, weather, and improper installation, can cause granule loss. If you’ve had your roof for over ten years, it may be time to replace the shingles. In addition, if the previous roofer did not install the shingles properly, the granules may not have been securely attached to the shingles and can be more easily removed.

3. Sagging Roof

Sagging roofs are typically a sign of structural damage and can be caused by various things, such as inadequate insulation, improper installation, or water damage. Even if your roof shingles still look relatively in good shape, you’ll need to repair your roofing to address the underlying structural damage.

4. Moss or Algae Growth

Moss and algae growth on roof shingles indicates a moisture problem that can quickly escalate into more severe issues if not taken care of. Moss and algae growth on a roof can cause various problems, from cosmetic damage to the roof’s structure. Another serious problem caused by moss and algae growth is the potential for rot and decay. The organisms can trap moisture beneath the shingles and cause the underlying wood to rot. This can cause significant damage to the roof structure and can even cause leaks.

5. Sunlight Coming through the Roof

This can signify a damaged or worn roof that needs to be replaced. Keep in mind that where sunshine can pass through, water can easily penetrate as well. If you see sunlight coming through the roof, address it immediately before the rain. This way, you won’t be stuck with a leaky roof during stormy weather.

6. Leaks or Water Damage

Leaks and water damage are a surefire way to tell if your roof needs replacing and should be addressed immediately, as they can lead to more extensive damage if left untreated. Water entering the roof space can cause structural damage, mold, and eventually rot. This can lead to costly repairs and cause health concerns for anyone living or working in the building.


Roof shingles are a great way to protect your home from the elements, but over time it can become worn and damaged and need replacing. Replacing a shingle roof is a big job, but it can be done with the help of a professional roofer. They will be able to inspect the roof, recommend the best materials, and install the new shingles.
