Your roof is the unsung hero of your home, protecting you and your loved ones from the elements year-round. But like any hero, it too can fall victim to wear and tear over time. As roofing experts in Riverside, CA we know the importance of keeping a watchful eye on your roof’s condition. While some signs of damage may be glaringly obvious, others can creep up on you without warning. In this article, we’ll unveil four hidden red flags of a damaged roof that you may have never considered. Pay attention to the signs we discuss below to avoid costly repairs down the road and keep your roof in tip-top shape.

  1. Loss of GranulesAged Asphalt Shingle Granules

Asphalt shingles are the most commonly used shingles in residential homes to shield the property from the weather. The granules on the surface of the shingles are a crucial component, as they reflect the sun’s rays and prevent the shingles from deteriorating rapidly.

Over time, these granules can loosen or wear away, leading to bare spots on your shingles or granules in your gutters or downspouts. This can result in premature aging and cracking of your shingles, causing leaks and water damage to the interior of your home.

  1. Curling Shingles

Another issue with asphalt shingles is curling, which can occur when the edges turn up or the middle sags down. This can happen due to exposure to the sun, age, or poor ventilation in the attic. Curling shingles can allow water to seep underneath, damaging the underlying roof structure. Moreover, they are more prone to wind damage and can easily blow off during a storm.

If you notice any of these issues, it’s crucial to have your roof inspected by a professional roofing contractor like Gary Thompson at Thompson Roofing to determine the extent of the damage. Allowing minor damage to your roof could cost you more in the long run. Give us a call at 909-377-4402 for a free inspection.

If flashing is damaged or missing, water can easily seep into your home and cause damage to the interior. Flashing can become damaged due to age, exposure to the elements, or improper installation.

One of the most common signs of damage is the appearance of exposed or loose nail heads. These nails may become dislodged due to weather conditions like high winds or improper installation, leaving behind holes and spaces that are vulnerable to water penetration.

When water seeps through these gaps, it can cause damage to the underlayment of the roof and eventually lead to leaks. If left unaddressed, this moisture can cause severe damage to your roof, and you may be forced to replace it sooner than expected.

So, it’s essential to inspect your asphalt shingle roof regularly and take action promptly if you notice any signs of damage, such as exposed or loose nail heads.
