How to Know When to Replace Roof Shingles

Shingles are an essential component of any roof, providing protection from the elements and helping to create an aesthetically pleasing exterior. However, over time shingles can become worn and damaged, leaving your home vulnerable to leaks and drafts. So how can you tell when it’s time to replace your roof shingles? There are a few telltale signs to look out for.

Asphalt Shingles

Asphalt shingles generally have an expected useful life.  Three-tab shingles are designed to last approximately twenty years.  Most architectural shingles are designed to last thirty years, although luxury shingles can be rated to last for up to fifty years.  Shingles act as the protective layer for the underlayment, which is the waterproofing agent for your roof.  As shingles wear, the underlayment can be vulnerable to damage and lead to leaks.  Signs that it is time to replace your shingles include the following:

  1. Weathering of the shingles that results in granule loss (the tiny crushed stone and minerals embedded in the asphalt).  The granules act as a protective layer for the asphalt.  As the shingles lose the granules, the underlying asphalt begins to deteriorate more quickly, oxidizing into a gray color rather than a deep black.  This is normal and all part of normal wear and tear on a roof.
  2. Wind damage - Colorado’s high winds can cause shingles to uplift, breaking the adhesive bonds and pulling through the nails that hold the shingles down.  Wind damage can take the form of missing shingles that have blown off or shingles that have lifted up and folded over, leaving a crease in the shingle and breaking the adhesive bond.
  3. Hail damage - Hail impacts to your roof can fracture the shingle and dislodge the granules that act as a protective layer for the asphalt, accelerating the wear of the shingle as well as ruining the shingles aesthetic. Hail also can expose the underlayment of your roof, leaving it vulnerable to roof leaks.
  4. Leaks - It probably goes without saying, but if your roof regularly leaks, it may be time to replace it.  Extensive water damage to the underlying roof deck can necessitate replacement of your roof.  It’s best to repair a leaking roof immediately to prevent further damage.  

The average lifespan of a roof is around 20 years.

The average lifespan of a roof is around 20 years. If your roof is starting to show signs of wear and tear, it might be time for a replacement. You can tell if you need a new roof by looking for the following clues: missing or broken shingles, granular loss, buckling, curling, or excessive algae growth. If you have a leaky roof, that’s another sign that it’s time for a replacement. And finally, if your home is more than 20 years old, it’s probably time for a new roof whether you see any of these other signs or not.
