​​How To Know Your Shingles Are Aging or Damaged?

Keep an eye out for these key signs of roof damage:

Balding Roof Shingles


Asphalt shingles consist of fiberglass mat, asphalt coating, and protective granules. Over time, granules deteriorate, exposing the fiberglass. This indicates your shingles are nearing the end of its lifespan, which happens quicker in hot climates. Lack of proper attic ventilation can also accelerate this process, heating your roof from the top and bottom.

Wood Rot


Look for signs of wood rot on the eaves, fascia (boards behind gutters), or exposed beams. This can be caused by repeated water exposure or improper ventilation. We typically recommend to keep things well-painted to avoid water from getting to the wood. Over time, this can be hard to keep an eye on so its important to have roof inspections throughout your roof’s lifetime.

Missing or Damaged Shingles


Shingles can detach due to wind, old age, improper installation, or overhanging tree branches that can disrupt the integrity of your roof. With missing shingles, you can compromise your roof's protection against water and extreme sun exposure wearing down your underlayment.

Exposed Nail Heads


​​​​A nail head doesn’t seem like a huge deal, but this couldn’t be further from the truth. Shingles should fully cover nail heads. Exposed heads, left out to overexposure, are susceptible to rust which breaks down the nail and creates water entry points. This can be the silent culprit to many roof leaks.

Improper Roof Installation


Incorrect or missing nail placement weakens the shingle's hold and can lead to them blowing off or allowing water to run through them. Additionally, uneven coursing (shingle rows not lining up) is usually a sign of a rushed or careless installation as we can see on this Simi Valley home.

Missing Ridge Cap


The ridge cap covers the peak of the roof. A missing cap exposes the underlying shingles to the elements and increases your risk of getting roof leaks.

Lack of Flashing


Flashing is commonly used around chimneys, pipes, and roof transitions (like where shingles meet a flat roof). Missing flashing creates vulnerabilities for water infiltration. If you have solar, proper flashing is even more important due to the penetrations your solar panel mounts are making into your roof.

Roof Repairs


While minor repairs are ok, they aren’t a permanent fix. Extensive patching can indicate underlying problems especially when they are recurring and suggests your roof is nearing the end of its useful life.
