Top Signs Your Roof is Past Its Prime

Curled or Buckling Shingles

If you notice that the shingles on your roof are curling or buckling, it may be a sign of more significant problems. These symptoms usually indicate an excess of moisture or inadequate ventilation in the attic. Excess moisture is particularly concerning because it means that the shingles are absorbing water instead of repelling it. This absorption can cause the underlying wood decking to deteriorate and rot over time, leading to even more severe issues. Additionally, poor ventilation or insufficient insulation in the attic can contribute to these problems. Proper ventilation is crucial for allowing the attic to "breathe" and remove any moisture that naturally accumulates in the home, preventing it from damaging the wood decking.

Missing Shingles

When a roof is missing shingles, it is in a highly vulnerable state and is likely to start leaking soon, if it hasn't aready. Roofing shingles are all installed as part of a unified system where each shingle relies on the others to form a truly waterproof barrier. When shingles are absent, typically as a result of storms or strong winds, it undermines the strength and effectiveness of the entire roofing system. If you notice any missing shingles on your roof, it is crucial to take immediate action to repair or replace them. Delaying the necessary repairs could lead to further damage and costly consequences in the future.

Excess Granules in the Gutter

While it is common to find small granules from your roof shingles in the gutter occasionally, if you observe significant amounts of granules in the downspouts or gutters after a rainfall, it is a clear indication that the shingles are deteriorating and aging. These granules act as the primary layer of protection for your roof, and their loss raises concerns about the overall integrity of the shingles. Once you notice a buildup of granules in the gutters or downspouts, it is advisable to seek estimates for a replacement. At this point, the roof is no longer fulfilling its intended purpose and requires immediate attention.

Interior Water Leaks or Staining

If your roof is already leaking and allowing water to come into your home, it is a clear sign that you require immediate attention. At this stage, a serious repair or even a complete roof replacement might be necessary. The fact that water is infiltrating your home indicates that the roof is no longer providing adequate protection against the elements. It is crucial to contact a professional roofing expert who can conduct a comprehensive inspection to determine the extent of the roofing issues or damage. Delaying this inspection any further could have disastrous consequences for the interior of your home. Take immediate action to ensure the safety and integrity of your property.

Bowing or Sagging of the Roof

If you notice sections of your roof starting to dip or sag, you are most likely experiencing significant problems with your roofing system. The bowing or sagging of the roof is a result of the underlying plywood or wood decking absorbing water over a prolonged period. This continuous water absorption has compromised the integrity of the wood, leaving it waterlogged and vulnerable. It is only a matter of time before this compromised wood starts to leak, allowing water to enter your home. It is crucial to address this issue promptly to prevent further damage and protect your property from potential water damage.

Missing Granules on Shingles

As noted with granules in your gutters, a small amount of granules off the shingles is not a major concern. However, if your shingles resemble the one shown in the picture above, it is a clear indication that your roof is no longer in good condition and overdue for a replacement. Granules play a crucial role in protecting the shingles, and once they are gone, the underlying fiberglass mat is left exposed. This makes your roof vulnerable to leaks, and it is only a matter of time before water seeps through if it hasn't already. It is important to address this issue promptly to avoid further damage and costly repairs.

Moss or Algae Growth on the Roof

Moss or algae growth on your roof could be a sign of excessive moisture being retained by the shingles. While the presence of a few spots might not be cause for concern, consistent patterns or extensive areas covered in growth indicate that the shingles are retaining water. Left unattended, this can lead to damage to the underlying wood decking, increasing the cost of future replacement. If you observe such growth, it is a telltale sign that the roof is past it's useful life, and time to be replaced.
